Evaluation of soil nutrients about typical economic forest lands of low hilly areas in eastern part of Zhejiang Province

Abstract

Through sampling of seven economic forest lands in low hilly areas of Zhejiang province the samples were tested, including soil organic matter, total nitrogen, available phosphorus and available potassium. The characteristics of soil nutrients in different economic forest lands were analysed by statistical method and the comprehensive evaluation of soil nutrient quality was carried out. The results showed that there were differences in soil nutrient contents in different economic forest lands. The overall status of soil nutrients in the economic forest land is in the "good" level; Among them, the content of soil organic matter and total nitrogen in the economic forest land were relatively abundant, However, the content of available potassium in soil was not enough, which was the main limiting factor for the development of economic forest land.
