Abstract: In order to test and verify application effect of fertilization on soybean by TRPF system of soil testing and fertilizer recommendation in sanjiang plain,and to test soft system, setting up different fertilization treatments in different fields between 2013 and 2014. By testing and analyzing on yield, outup value, fertilizer input amounts , economic benefits and so on, the result showed that the fertilizer input amounts of fertilization treatment on hight fertilization amount(HF) had been maximum at jiamusi experiment plot,and they were 1380 yuan per hectare in 2013,and 1374 yuan per hectare in 2014.The profits of TRPF treatment were largest in those two years. The increase income of TRPF treatment was 706.9 yuan per hectare comparing with the conventional fertilization in 2013, and 1254.1 yuan per hectare in 2014. The outup value of HF was the second,but the economic profit was lower comparing with these three treatment of TRPF. At the 853 farm experiment plot, the fertilizer input amounts of experience fertilization had been maximum ,and they were 780 yuan per hectare in 2013,and 765 yuan per hectare in 2014.The profits of TRPF treatment were largest in those two years.The increase income of TRPF treatment was 2102.2 yuan per hectare comparing with the conventional fertilization in 2013, and 1567.3 yuan per hectare in 2014. The increase income of TRPF treatment was 1184.2 yuan per hectare comparing with the experience fertilization in 2013, and 1266.1 yuan per hectare in 2014.This research had proved the good effect on TRPF system by analysing increaserate,fertilizer input amounts and economic profit.The income aspect of formula on TRPF are better than HF,LF,TR, EF and CK.
