Conservation tillage influence on topsoil aggregation and carbon content on the Loess Plateau,China

摘要：

In the Loess Plateau, the deterioration of the environment and in particular soil erosion are severe.In addition to frequent droughts in the area, soil is characterized as both having poor structural stability and as being infertile.Conservation tillage is believed to have beneficial effects on agricultural production, the environment and the economy.This paper reports the findings of a study which investigated the soil aggregation stability, total carbon, organic carbon and inorganic carbon under different tillage methods, in doing so it has aimed to confirm which tillage method and soil management program is most suited to the Loess Plateau.
