Title: Characteristics of peat soil nutrients in Gahai wetland of Gansu Province
Abstract: The characteristics of peat soil nutrients in Gahai wetland of Gansu Province were studied by the methods of field sampling and lab measurement.The results showed that the mean contents of organic matter,total nitrogen,total phosphorus and total potassium of peat soil were 302.04 g·kg-1,10.37 g·kg-1,0.81 g·kg-1 and 13.93 g·kg-1 respectively,and their spatial variabilities were all on the middle level.With the increasing of soil depth,the contents of organic matter,total nitrogen and total phosphorus were all decreased gradually while that of total potassium declined firstly and then increased.In different site conditions,the contents of soil organic matter,total nitrogen and total phosphorus were in the order of sunny slopeshady slopethe interdune depression,while the total potassium content was oppsite.The spatial variabilities of most soil nutrient contents in different site conditions were medium.The variation extent of soil nutrient contents in shady slope was higher than that in sunny slope.
