[Construction effect of fertile cultivated layer in albic soil Ⅰ Effects of inversion tillage with organic mate-rials on the redistribution of organic matter in surface layer of albic soil].

Soil organic matter serves as a crucial indicator for soil quality. Albic soil, characterized by a barrier layer, exhibits limitations in organic matter content, which can adversely affect crop growth and development. To elucidate the impact of deep mixing of various organic materials on the redistribution of organic matter in the surface soil of albic soil could provide theoretical and technical insights for establishing suitable plough layers for albic soil in Northeast China.
