Fertilizer Utilization Rate in Formula Fertilization by Soil Testing on Maize in Yuqing

Wang Sen-f

Abstract

To study formula fertilization by soil testing and NPK fertilizer utilization rate on maize,formula fertilization by soil testing and traditional fertilization were comparatively studied.The results showed that yield of formula fertilization by soil testing is 65.3kg/667m2 greater than traditional fertilization,greater 11.25%,and NPK fertilizer ultization of formula fertilization by soi testing are 9.40 %,3.08 %,6.22 % greater than traditional fertilization.It's indicated that the fertilizer rate and proportion is reasonable,which can increase the yield of maize,decrease the cost and increase the benefits,and increase the NPK fertilizer utilization rate.
