Studies on the effect of the fertilizer synergist that using proper prescription of zeolite,sodium humic and other inorganic and organic materials on spring soybeans showed that the fertilizer synergist could significantly increased the yield of soybeans compared with no fertilizer applied treatment.Under the three conditions of applied 300 kg per hectare of urea,diammonium orthophosphate,calcium superphosphate,substitution these three kinds of fertilizers with fertilizer synergist in the scale of 25%,50% and 75% in amounts showed that treatments of 75% fertilizer substituted with fertilizer synergist could get the highest soybeans yield,and increasing yield by 20.3%,5.7% and 1.2% higher than 100% urea,100% diammonium orthophosphate and 100% calcium superphosphate application,representing good effects of fertilizer-saving and increasing fertilizer efficiency.
