【Abstract】 The focus of the study is on the effect of the dosage of two complexants on the concentration of secondary and micro-nutrients in foliar fertilizers. The results show that the addition of a complexant at a rational dosage will markedly increase the concentration of secondary and trace elements in foliar fertilizers. A method is also proposed to formulate foliar fertilizers based on NPK with the addition of secondary and micro-nutrients in line with the results of the theoretical study.更多还原
