Effects of agricultural activities and transgenic crops on agricultural biodiversity. Effects of whole field soil-plastic mulching on soil thermal-moisture status and wheat yield in semiarid region on Northwest Loess Plateau Effects of potato-fababean intercropping on crop productivity and soil water under a plastic mulch and ridge-furrow planting system in a semiarid area Effects of Mini-ditch Planting with Plastic Mulching in Ridges on Soil Water Content, Temperature and Potato Yield in Rain-fed Semiarid Region Effect of plastic mulching along with deep burial of straw on dynamics of salinized soil respiration and its affecting factors Study on physiological and biochemical mechanism of increasing yield of spring wheat by using plastic mulching Effect of long-term conservation tillage on soil water regimes and leaf water potential of crops in rainfed areas of the Loess Plateau Effects of straw and plastic-film mulching on soil micro-bioactivity and organic carbon and nitrogen in northwest dryland areas of China Coupling effect of water and nitrogen of cotton under plastic mulching by drip irrigation Effects of conservation tillage on soil water regimes in rainfed areas
