Recently, the Ministry of Agriculture of the Fertilization early rice soil testing results of the application of scheduling, involving nine early rice-producing province 379 project counties. According to the analysis, 379 project counties early rice acreage 8682 acres, soil testing Fertilization to promote an area of 6130 mu. Among them, the establishment of soil testing and fertilizer formulation the core area of 659.3 mu demonstration area. The findings show that early rice soil testing and fertilizer application effects formula obviously.
     (A) to optimize the structure fertilization. Through soil testing, fertilizer formula to optimize the fertilizer ratio, improved fertilization structures. From the survey data analysis, in 2009, used to fertilize areas of 24.5 kilograms per acre fertilizer, nitrogen fertilizer, phosphate fertilizer, potash fertilizer were 12.8 kilograms, 6.4 kilograms, 5.3 kilograms. Fertilization of early rice soil testing the core demonstration areas dosage of 22.9 kilograms per acre fertilizer, nitrogen fertilizer, phosphate fertilizer, potash fertilizer was 10.7 kilograms, 5.0 kilograms, 7.2 kilograms of nitrogen, phosphorus and potash fertilizer used to feed formula proportion of 1:0.50: 0.41 optimal adjustment of 1:0.46:0.67.
     (B) to promote increased yields. Fertilization through the implementation of soil testing, the core demonstration areas, radiation, promote the area to increase yields in varying degrees. The core demonstration areas, compared with the fertilizer practice, mu yield 42.4 kilograms, an increase of 8.5%.
     (C) increase fertilizer efficiency. Fertilization through the implementation of soil testing, fertilizer contribution to food production has improved significantly. According to statistics, soil testing and fertilizer formulation of radiation zone and the core demonstration areas to promote the contribution rate of fertilizer, respectively 62% and 68%, respectively, than the habit of fertilizing areas increased by 10 percentage points and 16 percentage points. Meanwhile, the fertilizer quantity and structure of the more reasonable. The core demonstration areas fertilizer use per mu compared with customary fertilizer area decreased by 1.6 kg, of which 2.1 kg reduction in nitrogen fertilizer, phosphate fertilizer consumption decreased by 1.4 kilograms and 1.9 kilograms and the increased use of potash fertilizer.
     (Iv) the promotion of peasant incomes. Fertilization through the implementation of soil testing to promote the efficiency of the section of agriculture and peasant incomes. Fertilization, in comparison with the habit of early rice soil testing the core demonstration areas Fertilization efficiency of the section 60.0 yuan per mu, of which 54.0 yuan per mu yield income, abridged income 6.0 yuan.
