Investigations on soil fertility of Medicago varia and Bromus inermis stands

摘要：

The effects of forage cropping on soil fertility have not been well determined even though positive results have been reported for some spieces in certain areas (Cadisch et al.,1994 ; Jianguo Han et al.,2004).The objective of this study was to determine the changes of soil organic matter and soil available nitrogen of Medicago v aria and Bromus inermis stands during the subsequent years after establishment.
