All the mulches improved the water storage to some extent and led to warmer soils. However, the organic C and total N contents of the soils declined significantly under the mulches, particularly the plastic film mulches,and this could have long-term detrimental effects on soil quality and the sustainability of the some mulching practices.展开更多
