Abstract: The objective is to study balancing fertilization scenario by determining the appropriate dosage of nitrogen, phosphor and potassium after balancing microelements which are deficient in soil according to soil nutrients status from result of soil nutrients systematic evaluation method that adopted to study soil nutrients. results of the experiment show that balancing application of nitrogen, phosphor, potassium and microelements can improve economic character of wheat and maize seeds and increase thousands grain weight of wheat and maize seeds, seeds number and seeds weight per spike of maize. Nitrogen and phosphor are the main limited factors to increase wheat yield. Nitrogen, phosphor and potassium are the main limited factors to increase maize yield after balancing microelement. The yield and product value and net income of treatments with balancing fertilization increased, of which treated by N2P2K2 is the highest, which are 17085 Yuan/hm2 and 15240 Yuan/hm2 respectively. The high yield balancing fertilization scenario should be N2P2K2 according to the integrated analysis of above result.
