By the method of soil sampling and laboratory analysis
effects of different land use types on soil nutrients have been discussed. The result indicated
the different land use types have significant impacts on soil nutrient. The content of soil organic matter and total N decline in sequence from paddy land
forest land
vegetable land
dry land to grassland. The content of soil total K and available K decline in sequence from paddy land
vegetable land
dry land
forest land to grassland. The content of soil total P decline in sequence from vegetable land
