Fertility of Red Upland Soil and Effects of Fertilization and Utilization on its Fertility

Red upland soil is an important soil type in the South China,but the acidity is strong and exchange acid content is over 4.41 cmol(+) kg~(-1). There is lower organic matter and nutrient contents in red upland soil.Application of fertilizer is one of the most important practices for red upland soil,and combied use of organic aod inorganic fertilizers can improve the fertility of red upland soil.The utilization mode can also impact the fertility of red upland soil.Therefor,we conducted a study aiming to improving soil fertility and reducing nutrient coss by proper fertilizatoin and land use.
