It is advisable to apply high yield and high yield of crops.

Q: If you want high yield and high yield of crops, how much is it appropriate?

A: As the saying goes, crops and flowers are all dependent on fat. There are more than 20 kinds of nutrients needed for crop growth, among which carbon, hydrogen and oxygen can be obtained from the air, and generally do not need to be provided in the form of fertilizer. Nitrogen, phosphorus and potassium are high in the body of the crop and are absorbed more. They are called “mass elements” and are less abundant in the soil. They need to be supplemented in the form of fertilizers, so they are called “three elements of fertilizer”. Copper, zinc, iron, manganese, boron, molybdenum and other elements, the amount of crops required is called “trace elements”. Generally, the medium and trace elements contained in the soil can meet the needs of crops, and soils that are particularly sensitive to some trace elements. It must be supplemented with the corresponding medium and trace element fertilizer.
