Abstract:

To solve the excessive use of chemical fertilizer and reduce environmental pollution, we promote precise fertilization. In this study, a formula fertilization system was developed by using Visual Basic language and nutrient balance fertilization method, fertilizer application was calculated by five parameters: fertilizer demand, soil fertilizer supply, fertilizer utilization, target yield and available nutrient content in fertilizer. Under the premise of constant yield, it provided the most scientific and minimum fertilizer application. This system could accurately, efficiently and scientifically complete the work of formula fertilization.
