A Systematic Study on Nutrient Status and its Application in Balanced Fertilization |
| |
| Abstract: | Flove-aquic soil and Castano-cinnamon soil,which were collected from Linyi and Liulin respectively were studied with a systematic approach technique on soil nutrient status.It indicates that the effect of use this method is good.Use of this technique can relatively comprehensively reflect soil nutrient status and further indicate the limiting factor of trial so as to enhance the veracity of filed experiment.So it provides the new and powerful theory and method for fertilizer recommendation and balanced fertilization,and its applying foreground is very broad. |
