Abstract: In the purpose of rapidly increasing soil nutrient concentration and rapid fertilization of newly-increased cultivated land. And ensure crop growth and food production. Different fertilizers were put into soil to form a fertilizer test and the effect on soil nutrient concentration were analyzed. The result showed thatsoil organic mater increasing was the highest and pH was lowest with commercial organic fertilizer input. It is better for rice growth. Soil nitrate nitrogen and ammonium nitrogen was the highest with urea+superphosphate+muriate+commercial organic fertilizer input. It is good for increasing available N concentration. The urea+superphosphate+muriate+commercial organic fertilizer treatment was the best for new arable land fertilizer. Available potassium was higher in muriate input treatment than in potassium sulphate treatment.

Key words: nutrient, fertility, organic mater, available potassium, nitrate nitrogen, ammonium nitrogen
