It has become an important measure for high quality and high yield of contemporary agriculture by applying micro-fertilizer to meet crop demand. The trace element needs are very small, and it is easily fixed by the soil. The foliar application effect is better than the soil application. The types and application methods of trace element fertilizers are mainly as follows:
Boron fertilizer: varieties include borax, boric acid, boron magnesium fertilizer, etc. Borax and boric acid are commonly used boron fertilizers. The soil application is 0.5-0.75kg per mu, the foliar spray concentration is 0.1%-0.3%, the soaking concentration is 0.01%-0.1%, and the seed dressing is 0.2-0.5g per kg of seeds.
î—¥ î—¥ manganese fertilizer: varieties of manganese sulfate, manganese carbonate, manganese chloride, manganese oxide and so on. Manganese sulfate is a commonly used manganese fertilizer. The soil application is 1-2kg per mu, the foliar spray concentration is 0.05%-0.2%, the soaking concentration is 0.05%-0.1%, and the seed dressing is 4-8g per kg of seeds.
î—¥ î—¥ copper fertilizer: varieties of copper sulfate, copper oxide, chelated copper, copper slag and so on. Copper sulphate is commonly used copper fertilizer, soil application is 0.8-1.5kg per mu, foliar spray concentration is 0.01%-0.05%, soaking concentration is 0.01%-0.05%, and seed dressing is 300mg per kg of seed.
Iron fertilizer: varieties include ferrous sulfate, ammonium ferrous sulfate, iron chelate and so on. Ferrous sulfate is a common variety, the soil application is 5kg per acre, and the foliar spray concentration is 0.5%-0.3%.
î—¥ î—¥ zinc fertilizer: varieties of zinc sulfate, zinc oxide, zinc chloride and so on. Zinc sulphate is commonly used zinc fertilizer, soil application is 1-2kg per mu, foliar spray concentration is 0.01%-0.05%, soaking concentration is 0.02%-0.05%, and seed dressing is 1-3g per kg of seed.
Molybdenum fertilizer: The varieties include ammonium molybdate, sodium molybdate, and molybdenum trioxide. Ammonium molybdate is a commonly used molybdenum fertilizer. The soil application is 50-150g per mu, the spraying concentration is 0.01%-0.1%, the soaking concentration is 0.05%-0.1%, and the seed dressing is 2-5g per kg of seeds. Source: Hebei Farmers Daily
