Safe application of micro-fertilizer on vegetables

Although the demand for trace elements is very small in the growth and development of vegetables, it has a great effect, and its role is not replaced by a large number of elements such as nitrogen, phosphorus and potassium. However, vegetables have a narrow range of concentrations from a lack of excess to a certain amount of trace elements, and if applied excessively or unevenly applied, they can cause toxic side effects on vegetables. In order to enable farmers to safely use micro-fertilizers on vegetables, the safe application of several micro-fertilizers on vegetables is described below.
First, molybdenum fertilizer. Common ammonium molybdate. The soil use is 30-200 grams per acre, the soaking concentration is 0.05-0.1%; the seed dressing is 2-6 grams per kilogram of seeds; the foliar spray concentration is 0.02-0.05%.
Second, iron fertilizer. Commonly used ferrous sulfate. The amount of soil applied is 1.5-3.75 kg per seed; the soaking concentration is 0.02-0.05%.
Third, zinc fertilizer. Commonly used zinc sulfate. The soil use amount is 1.5-2.0 kg per acre; the soaking concentration is 0.02-0.05%; the foliar spray concentration is 0.1-0.5%.
Fourth, boron fertilizer. Commonly used borax or boric acid. The soil use amount is 0.75-1.25 kg per acre; the soaking concentration is 0.02-0.05%; the foliar spray concentration is 0.3-0.5%.
Five, manganese fertilizer. Commonly used manganese sulfate or manganese chloride. The soil use amount is 1-1.25 kg per mu; the soaking concentration is 0.01-0.05%; the foliar spray concentration is 0.3-0.5%.
Sixth, copper fertilizer. Commonly used copper sulfate. The soil use amount is 1.5-2.0 kg per mu; the soaking concentration is 0.01-0.05%; the foliar spray concentration is 0.02-0.04%.
