Abstract

Soil and fertilizer station of Donzhi County collected and analysed 3780 soil samples after autumn harvest from 2006 to 2012 in Dongzhi county. The results showed that the average organic matter level in paddy field soil was 26.78 g/kg; the average total nitrogen level was 1.67 g/kg, the average available phosphorus level was 19.16 mg/kg, the average available potassium level was 88.42 mg/kg, and the average pH value was 5.23. Compared to the results of the second national soil survey, the contents of organic matter, total nitrogen, available phosphorus and available potassium increased, and the increasing order of the growth rate were available phosphorus > available potassium> total nitrogen > organic matter. However, the pH value of paddy field soil decreased.
