| Abstract: | Soil nutrient analysis was carried out in Kunshan City in 2009.The results showed that the mean value of soil organic matter, total nitrogen, alkaline hydrolysis nitrogen, Olsen-P, HA-K and pH was 35.5 g·kg-1, 2.22 g·kg-1, 162 mg·kg-1, 15.1 mg·kg-1, 115 mg·kg-1and 6.0,respectively. Compared with the results of 1981, the soil organic matter,total nitrogen content showed a tendency of increasing, and alka-line hydrolysis nitrogen, Olsen-P, HA-K content showed a sharp rise, but pH value showed a tendency of decreasing. |
