First, the modification of the reasons from the biological characteristics of soybeans and the nature of the decision, many years ago in agricultural production proposed that the same species of fertilizer can not be sown together with the soil, to the side of the seed 3 cm, 5 cm deeper than the seed Agronomic requirements. Over the years, various units have carried out various forms of deep fertilizer modification on seed drill, and all have achieved some success.
