Abstract: | The black soil in northeast China is considered one of the most fertile soils in China. Consequently, the black soil region has become one of the most important regions for cereal grain production in China. Agriculture has developed rapidly since the early part of the nineteenth century. To date, approximately 70 percent of total land in the area is cultivated. Even though the agricultural production in this region is increasing continuously, some soil fertility quality problems have become serious. This is hampering agricultural development and sustainability in the region. A brief history of population growth and agricultural development in the region is presented. Major soil quality problems, particularly soil degradation and soil erosion, are analyzed. Based on studies, suggestions for improving soil quality and for promoting sustainable agricultural development in the region are presented. These suggestions include improving agricultural landscape patterns, developing conservation cultivation, promoting combinations of crop production with combinations of forestry and animal husbandry, and implementing integrated management for soil and water conservation. |
