摘要： An experiment was conducted by fertilizer packet burying method to determine the nitrogen release of SCU, PSCU and PCU in the soil during corn and wheat planting period. Results showed that Packet burying method can be used to measure the nitrogen release characteristics of coated controlled release urea in soil. This test method can simulate the nutrient release situation of controlled release fertilizer applied in soil. It plays an important role in fitting fertilizer demand with fertilizer supply during plant growth period as well as improving the precision of controlled release fertilizer using.
