The name most likely derived from the mythical island of California in the fictional story of Queen Calafia , as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo . Queen Calafia's kingdom was said to be a remote land rich in gold and pearls, inhabited by beautiful Black women who wore gold armor and lived like Amazons , as well as griffins and other strange beasts. Abbreviations of

436-676: A boom in using nitrogen fertilizers. In the latter half of the 20th century, increased use of nitrogen fertilizers (800% increase between 1961 and 2019) has been a crucial component of the increased productivity of conventional food systems (more than 30% per capita) as part of the so-called " Green Revolution ". The use of artificial and industrially-applied fertilizers has caused environmental consequences such as water pollution and eutrophication due to nutritional runoff; carbon and other emissions from fertilizer production and mining; and contamination and pollution of soil . Various sustainable agriculture practices can be implemented to reduce

545-598: A commodity until the 1849 California Gold Rush . From the 1820s, trappers and settlers from the United States and Canada began to arrive in Northern California. These new arrivals used the Siskiyou Trail , California Trail , Oregon Trail and Old Spanish Trail to cross the rugged mountains and harsh deserts in and surrounding California. The early government of the newly independent Mexico

Egyptians, Romans, Babylonians, and early Germans are all recorded as using minerals or manure to enhance the productivity of their farms. The scientific research of plant nutrition started well before the work of German chemist Justus von Liebig although his name

763-757: A fourth number for sulfur, and uses elemental values for all values including P and K. Micronutrients are consumed in smaller quantities and are present in plant tissue on the order of parts-per-million (ppm), ranging from 0.15 to 400 ppm or less than 0.04% dry matter. These elements are often required for enzymes essential to the plant's metabolism. Because these elements enable catalysts (enzymes), their impact far exceeds their weight%age. Typical micronutrients are boron , zinc , molybdenum , iron , and manganese . These elements are provided as water-soluble salts. Iron presents special problems because it converts to insoluble (bio-unavailable) compounds at moderate soil pH and phosphate concentrations. For this reason, iron

872-576: A free state, the "loitering or orphaned Indians", were de facto enslaved by their new Anglo-American masters under the 1850 Act for the Government and Protection of Indians . One of these de facto slave auctions was approved by the Los Angeles City Council and occurred for nearly twenty years. There were many massacres in which hundreds of indigenous people were killed by settlers for their land. Between 1850 and 1860,

It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With nearly 39   million residents across an area of 163,696 square miles (423,970 km ), it is the most populous U.S. state, the third-largest by area, and most populated subnational entity in North America . Prior to European colonization , California

2180-419: Is a rating system describing the amount of nitrogen, phosphorus, and potassium in a fertilizer. NPK ratings consist of three numbers separated by dashes (e.g., 10-10-10 or 16-4-8) describing the chemical content of fertilizers. The first number represents the percentage of nitrogen in the product; the second number, P 2 O 5 ; the third, K 2 O. Fertilizers do not actually contain P 2 O 5 or K 2 O, but

2289-441: Is an advantage for mechanical application. Urea is usually spread at rates of between 40 and 300 kg/ha (35 to 270 lbs/acre) but rates vary. Smaller applications incur lower losses due to leaching. During summer, urea is often spread just before or during rain to minimize losses from volatilization (a process wherein nitrogen is lost to the atmosphere as ammonia gas). Because of the high nitrogen concentration in urea, it

2398-549: Is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients . Fertilizers may be distinct from liming materials or other non-nutrient soil amendments . Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in

2507-420: Is called " fertigation ". Granulated fertilizers are more economical to ship and store, not to mention easier to apply. Urea is highly soluble in water and is therefore also very suitable for use in fertilizer solutions (in combination with ammonium nitrate: UAN), e.g., in 'foliar feed' fertilizers. For fertilizer use, granules are preferred over prills because of their narrower particle size distribution, which

2616-438: Is expected, urea can be side- or top-dressed during the growing season. Top-dressing is also popular on pasture and forage crops. In cultivating sugarcane, urea is side dressed after planting and applied to each ratoon crop. Because it absorbs moisture from the atmosphere, urea is often stored in closed containers. Overdose or placing urea near seed is harmful. Foliar fertilizers are applied directly to leaves. This method

2725-832: Is extremely soluble and mobile and is a major cause of eutrophication and algal bloom . Fertilizers are classified in several ways. They are classified according to whether they provide a single nutrient (e.g., K, P, or N), in which case they are classified as "straight fertilizers". "Multinutrient fertilizers" (or "complex fertilizers") provide two or more nutrients, for example, N and P. Fertilizers are also sometimes classified as inorganic (the topic of most of this article) versus organic. Inorganic fertilizers exclude carbon-containing materials except ureas . Organic fertilizers are usually (recycled) plant- or animal-derived matter. Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture. The main nitrogen-based straight fertilizer

2834-546: Is important to remove the calcium nitrate because calcium nitrate is extremely hygroscopic . " Organic fertilizers " can describe those fertilizers with a biologic origin—derived from living or formerly living materials. Organic fertilizers can also describe commercially available and frequently packaged products that strive to follow the expectations and restrictions adopted by " organic agriculture " and " environmentally friendly " gardening – related systems of food and plant production that significantly limit or strictly avoid

2943-468: Is most mentioned as the "father of the fertilizer industry". Nicolas Théodore de Saussure and scientific colleagues at the time were quick to disprove the simplifications of von Liebig. Prominent scientists whom von Liebig drew were Carl Ludwig Sprenger and Hermann Hellriegel . In this field, a 'knowledge erosion' took place, partly driven by an intermingling of economics and research. John Bennet Lawes , an English entrepreneur , began experimenting on

3052-512: Is often administered as a chelate complex , e.g., the EDTA or EDDHA derivatives. The micronutrient needs depend on the plant and the environment. For example, sugar beets appear to require boron , and legumes require cobalt , while environmental conditions such as heat or drought make boron less available for plants. The production of synthetic, or inorganic, fertilizers require prepared chemicals, whereas organic fertilizers are derived from

3161-450: Is required for the production of DNA ( genetic code ) and ATP , the main energy carrier in cells , as well as certain lipids ( phospholipids , the main components of the lipidic double layer of the cell membranes ). Two sets of enzymatic reactions are highly relevant to the efficiency of nitrogen-based fertilizers. The first is the hydrolysis (reaction with water) of urea ( CO(NH 2 ) 2 ). Many soil bacteria possess

The San Francisco Bay and the Greater Los Angeles areas are seen as the centers of the global technology and U.S. film industries, respectively. The Spaniards gave the name Las Californias to the peninsula of Baja California (in modern-day Mexico). As Spanish explorers and settlers moved north and inland,

3379-712: Is typically available as 0-0-60 or 0-0-62 fertilizer. These fertilizers are common. They consist of two or more nutrient components. Major two-component fertilizers provide both nitrogen and phosphorus to the plants. These are called NP fertilizers. The main NP fertilizers are About 85% of MAP and DAP fertilizers are soluble in water. NPK fertilizers are three-component fertilizers providing nitrogen, phosphorus, and potassium. There exist two types of NPK fertilizers: compound and blends. Compound NPK fertilizers contain chemically bound ingredients, while blended NPK fertilizers are physical mixtures of single nutrient components. NPK rating

3488-457: Is typically granulated or powdered. Often solids are available as prills , a solid globule. Liquid fertilizers comprise anhydrous ammonia, aqueous solutions of ammonia, aqueous solutions of ammonium nitrate or urea. These concentrated products may be diluted with water to form a concentrated liquid fertilizer (e.g., UAN ). Advantages of liquid fertilizer are its more rapid effect and easier coverage. The addition of fertilizer to irrigation water

3597-450: Is very important to achieve an even spread. Drilling must not occur on contact with or close to seed, due to the risk of germination damage. Urea dissolves in water for application as a spray or through irrigation systems. In grain and cotton crops, urea is often applied at the time of the last cultivation before planting. In high rainfall areas and on sandy soils (where nitrogen can be lost through leaching) and where good in-season rainfall

7848-410: The indigenous peoples developed complex forms of ecosystem management, including forest gardening to ensure the regular availability of food and medicinal plants . This was a form of sustainable agriculture . To mitigate destructive large wildfires from ravaging the natural environment, indigenous peoples developed a practice of controlled burning . This practice was recognized for its benefits by

7957-572: The interior and north of California. The Anza expedition selected numerous sites for missions, presidios, and pueblos, which subsequently would be established by settlers. Gabriel Moraga , a member of the expedition, would also christen many of California's prominent rivers with their names in 1775–1776, such as the Sacramento River and the San Joaquin River . After the expedition, Gabriel's son, José Joaquín Moraga , would found

8066-531: The largest dam removal and river restoration project in US history was announced for the Klamath River , as a win for California tribes. Covering an area of 163,696 sq mi (423,970 km ), California is the third-largest state in the United States in area, after Alaska and Texas . California is one of the most geographically diverse states in the union and is often geographically bisected into two regions, Southern California , comprising

8175-407: The largest producer and consumer of nitrogen fertilizers while Africa has little reliance on nitrogen fertilizers. Agricultural and chemical minerals are very important in industrial use of fertilizers, which is valued at approximately $ 200 billion. Nitrogen has a significant impact in the global mineral use, followed by potash and phosphate. The production of nitrogen has drastically increased since

8284-409: The largest user of each nutrient. A maize crop yielding 6–9 tonnes of grain per hectare (2.5 acres) requires 31–50 kilograms (68–110 lb) of phosphate fertilizer to be applied; soybean crops require about half, 20–25 kg per hectare. Yara International is the world's largest producer of nitrogen-based fertilizers. Fertilizers enhance the growth of plants. This goal is met in two ways,

8393-439: The materials have consumer appeal. No matter the definition nor composition, most of these products contain less-concentrated nutrients, and the nutrients are not as easily quantified. They can offer soil-building advantages as well as be appealing to those who are trying to farm / garden more "naturally". In terms of volume, peat is the most widely used packaged organic soil amendment. It is an immature form of coal and improves

8502-844: The middle of the state lies the California Central Valley , bounded by the Sierra Nevada in the east, the coastal mountain ranges in the west, the Cascade Range to the north and by the Tehachapi Mountains in the south. The Central Valley is California's productive agricultural heartland. Divided in two by the Sacramento-San Joaquin River Delta , the northern portion, the Sacramento Valley serves as

8611-537: The ore involves some purification steps, e.g., to remove sodium chloride (NaCl) (common salt ). Sometimes potash is referred to as K 2 O, as a matter of convenience to those describing the potassium content. In fact, potash fertilizers are usually potassium chloride , potassium sulfate , potassium carbonate , or potassium nitrate . There are three major routes for manufacturing NPK fertilizers (named for their main ingredients: nitrogen (N), phosphorus (P), and potassium (K)): Step 2. Removal of Calcium Nitrate. It

8720-629: The organic processes of plants and animals in biological processes using biochemicals. Nitrogen fertilizers are made from ammonia (NH 3 ) produced by the Haber–Bosch process . In this energy-intensive process, natural gas (CH 4 ) usually supplies the hydrogen , and the nitrogen (N 2 ) is derived from the air . This ammonia is used as a feedstock for all other nitrogen fertilizers, such as anhydrous ammonium nitrate (NH 4 NO 3 ) and urea (CO(NH 2 ) 2 ). Deposits of sodium nitrate (NaNO 3 ) ( Chilean saltpeter ) are also found in

8829-414: The population of San Francisco increased from 500 to 150,000. The seat of government for California under Spanish and later Mexican rule had been located in Monterey from 1777 until 1845. Pio Pico, the last Mexican governor of Alta California, had briefly moved the capital to Los Angeles in 1845. The United States consulate had also been located in Monterey, under consul Thomas O. Larkin . In 1849,

8938-594: The process was built in Rjukan and Notodden in Norway and large hydroelectric power facilities were built. The 1910s and 1920s witnessed the rise of the Haber process and the Ostwald process . The Haber process produces ammonia (NH 3 ) from methane (CH 4 ) ( natural gas ) gas and molecular nitrogen (N 2 ) from the air. The ammonia from the Haber process is then partially converted into nitric acid (HNO 3 ) in

9047-733: The pueblo of San Jose in 1777, making it the first civilian-established city in California. During this same period, sailors from the Russian Empire explored along the northern coast of California. In 1812, the Russian-American Company established a trading post and small fortification at Fort Ross on the North Coast . Fort Ross was primarily used to supply Russia's Alaskan colonies with food supplies. The settlement did not meet much success, failing to attract settlers or establish long term trade viability, and

9156-469: The races until the Indian race becomes extinct must be expected. While we cannot anticipate the result with but painful regret, the inevitable destiny of the race is beyond the power and wisdom of man to avert." As in other American states, indigenous peoples were forcibly removed from their lands by American settlers , like miners, ranchers, and farmers. Although California had entered the American union as

9265-403: The region known as California , or Las Californias , grew. Eventually it included lands north of the peninsula, Alta California , part of which became the present-day U.S. state of California. A 2017 state legislative document states, "Numerous theories exist as to the origin and meaning of the word 'California, ' " and that all anyone knows is the name was added to a map by 1541 "presumably by

9374-410: The size and quality of the remaining ore is decreasing. These minerals are converted into water-soluble phosphate salts by treatment with acids . The large production of sulfuric acid is primarily motivated by this application. In the nitrophosphate process or Odda process (invented in 1927), phosphate rock with up to a 20% phosphorus (P) content is dissolved with nitric acid (HNO 3 ) to produce

9483-442: The slaughter of animals – bloodmeal , bone meal , feather meal , hides, hoofs, and horns all are typical components. Organically derived materials available to industry such as sewage sludge may not be acceptable components of organic farming and gardening, because of factors ranging from residual contaminants to public perception. On the other hand, marketed "organic fertilizers" may include, and promote, processed organics because

9592-456: The soil by aeration and absorbing water but confers no nutritional value to the plants. It is therefore not a fertilizer as defined in the beginning of the article, but rather an amendment. Coir , (derived from coconut husks), bark, and sawdust when added to soil all act similarly (but not identically) to peat and are also considered organic soil amendments – or texturizers – because of their limited nutritive inputs. Some organic additives can have

9701-654: The state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882 Chinese Exclusion Act . Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which

9810-521: The state on March 4, 2020, and remained in effect until Governor Gavin Newsom ended it in February 2023. A mandatory statewide stay-at-home order was issued on March 19, 2020, which was ended in January 2021. Cultural and language revitalization efforts among indigenous Californians have progressed among tribes as of 2022. Some land returns to indigenous stewardship have occurred. In 2022,

9919-430: The state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains . Droughts and wildfires are an ongoing issue. California's economy is the largest of any U.S. state, with a $ 4.0 trillion gross state product as of 2024 . It is the largest sub-national economy in the world. California's agricultural industry has

10028-515: The state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Middle Easterns, Chinese and other immigrants during the great California gold rush . By the time of California's application for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854, more than 300,000 settlers had come. Between 1847 and 1870,

10137-522: The state's name include CA, Cal., Calif., Califas , and US-CA . California was one of the most culturally and linguistically diverse areas in pre-Columbian North America . Historians generally agree that there were at least 300,000 people living in California prior to European colonization. The Indigenous peoples of California included more than 70 distinct ethnic groups , inhabiting environments ranging from mountains and deserts to islands and redwood forests. Living in these diverse geographic areas,

10246-620: The state, and develop a high-tech region, now known as Silicon Valley . As a result of this, California is a world center of the entertainment and music industries, of technology, engineering, and the aerospace industry, and as the US center of agricultural production. Just before the Dot Com Bust , California had the fifth-largest economy in the world. In the mid and late twentieth century, race-related incidents occurred. Tensions between police and African Americans, combined with unemployment and poverty in inner cities, led to riots, such as

10355-499: The system is a conventional shorthand for the amount of the phosphorus (P) or potassium (K) in a fertilizer. A 50-pound (23 kg) bag of fertilizer labeled 16-4-8 contains 8 lb (3.6 kg) of nitrogen (16% of the 50 pounds), an amount of phosphorus equivalent to that in 2 pounds of P 2 O 5 (4% of 50 pounds), and 4 pounds of K 2 O (8% of 50 pounds). Most fertilizers are labeled according to this N-P-K convention, although Australian convention, following an N-P-K-S system, adds

10464-511: The ten southernmost counties, and Northern California , comprising the 48 northernmost counties. It is bordered by Oregon to the north, Nevada to the east and northeast, Arizona to the southeast, the Pacific Ocean to the west and shares an international border with the Mexican state of Baja California to the south (with which it makes up part of The Californias region of North America , alongside Baja California Sur ). In

10573-407: The time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the first transcontinental railroad was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state

10682-407: The traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration. This article, like many on fertilizers, emphasizes the nutritional aspect. Fertilizers typically provide, in varying proportions : The nutrients required for healthy plant life are classified according to

10791-570: The transition from Spanish colonial rule to independent Mexican rule. In 1821, the Mexican War of Independence gave the Mexican Empire (which included California) independence from Spain. For the next 25 years, Alta California remained a remote, sparsely populated, northwestern administrative district of the newly independent country of Mexico, which shortly after independence became a republic. The missions , which controlled most of

10900-568: The use of synthetic fertilizers and pesticides. The "organic fertilizer" products typically contain both some organic materials as well as acceptable additives such as nutritive rock powders, ground seashells (crab, oyster, etc.), other prepared products such as seed meal or kelp, and cultivated microorganisms and derivatives. Fertilizers of an organic origin (the first definition) include animal wastes , plant wastes from agriculture, seaweed , compost , and treated sewage sludge ( biosolids ). Beyond manures, animal sources can include products from

11009-572: The watershed of the Sacramento River , while the southern portion, the San Joaquin Valley is the watershed for the San Joaquin River . Both valleys derive their names from the rivers that flow through them. With dredging, the Sacramento and the San Joaquin Rivers have remained deep enough for several inland cities to be seaports . Fertilizer A fertilizer ( American English ) or fertiliser ( British English )

11118-496: Was 195 million tonnes of nutrients, of which 56% was nitrogen. Asia represented 53% of the world's total agricultural use of inorganic fertilizers in 2021, followed by the Americas (29%), Europe (12%), Africa (4%) and Oceania (2%). This ranking of the regions is the same for all nutrients. The main users of inorganic fertilizers are, in descending order, China, India, Brazil, and the United States of America (see Table 15), with China

11227-544: Was abandoned by 1841. During the War of Mexican Independence , Alta California was largely unaffected and uninvolved in the revolution, though many Californios supported independence from Spain , which many believed had neglected California and limited its development. Spain's trade monopoly on California had limited local trade prospects. Following Mexican independence, California ports were freely able to trade with foreign merchants. Governor Pablo Vicente de Solá presided over

11336-552: Was extremely well suited to fruit cultivation and agriculture in general. Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere. In the nineteenth century, a large number of migrants from China traveled to

11445-607: Was highly unstable, and in a reflection of this, from 1831 onwards, California also experienced a series of armed disputes, both internal and with the central Mexican government. During this tumultuous political period Juan Bautista Alvarado was able to secure the governorship during 1836–1842. The military action which first brought Alvarado to power had momentarily declared California to be an independent state, and had been aided by Anglo-American residents of California, including Isaac Graham . In 1840, one hundred of those residents who did not have passports were arrested, leading to

11554-714: Was not usually the purpose of these small-scale battles. Men and women generally had different roles in society. Women were often responsible for weaving, harvesting, processing, and preparing food, while men for hunting and other forms of physical labor. Most societies also had roles for people whom the Spanish referred to as joyas , who they saw as "men who dressed as women". Joyas were responsible for death , burial , and mourning rituals , and they performed women's social roles. Indigenous societies had terms such as two-spirit to refer to them. The Chumash referred to them as 'aqi. The early Spanish settlers detested and sought to eliminate them. The first Europeans to explore

11663-666: Was one of the most culturally and linguistically diverse areas in pre-Columbian North America . European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire . The area became a part of Mexico in 1821, following its successful war for independence , but was ceded to the United States in 1848 after the Mexican–American War . The California gold rush started in 1848 and led to social and demographic changes, including depopulation of Indigenous tribes. The western portion of Alta California

11772-502: Was short-lived; the same year marked the outbreak of the Mexican–American War (1846–1848). Commodore John D. Sloat of the United States Navy sailed into Monterey Bay in 1846 and began the U.S. military invasion of California , with Northern California capitulating in less than a month to the United States forces. In Southern California, Californios continued to resist American forces. Notable military engagements of

11881-399: Was then organized and admitted as the 31st state in 1850 , as a free state , following the Compromise of 1850 . The Greater Los Angeles and San Francisco Bay areas are the nation's second- and fifth-most populous urban regions , with 19 million and 10 million residents respectively. Los Angeles is the state's most populous city and the nation's second-most ; California's capital
