Studien av mikronäringsämnen började i början av 20 -talet av detta århundrade och är bara cirka 60 år gammal . Mikronäringsämnen är en del av växtnäringsforskning .
Studien av spårelement går utöver forskningen från jordforskare, jordbrukskemister och fysiologer, och ägnar också stor uppmärksamhet åt ekologer och experter inom miljövetenskap . Produktionen och utvecklingen av mikro-fertilisatorer är samma som för kväve, fosfor och kaliumdiktion, men det är bara födda med de bekräftade micronen) (nitrogen {)) Micro-Fertilizer har blivit ett av de stora framstegen inom växtmineraler, som har främjat en betydande ökning av grödor .
Micro-fertilizer has practical significance in agricultural production, so it was demonstrated and popularized in agriculture in the 30s. For example, in the Soviet Union, 2,700 tons of boron fertilizer (boron-magnesium fertilizer) were applied in 1937~1939. In the late 40s, the annual application of borax in the United States reached 4148 tons, and the annual use of zinc sulfate reached 3311 tons in the 50s. The annual use of micro-fertilizer in the Soviet Union amounted to 120,000 tons, and in the United States up to 200,000 tons. The production of micro-fertilizers in China has a history of more than 20 years. In 1964, the production of molybdenum fertilizer was first started in Jilin germanium plant, which had a significant effect on soybean yield. Since the 70s, the agricultural department and the relevant units of the Chinese Academy of Sciences have successively discovered that crops have symptoms of zinc, boron, iron, and manganese deficiency, which has attracted the attention of relevant departments. In 1981, the State Economic Commission and others jointly convened the first national conference on trace element fertilizers. In 1983, the total output of micro-fertilizer in China reached more than 20,000 tons, with 24 varieties and an application area of about 40 million mu.
