Advisory System for Corn Quantitative Fertilization in Hilly Red Soil Region in Zhejiang Province

Advisory system for corn quantitative fertilization was developed with the data of mutiple site field experiments of corn grown on hilly red soils in Zhejiang. The rate of P and K was computed with nutrient balance fertilization formula, and N was computed accoring to yield level of corn. System face design and integrated was completed with Visual Basic.
