A study was made of the effect of various methods of irrigation on yields of spring wheat and development of soil microorganisms in the cultivated layer and the layers below of dark-chestnut soil of the Saratov Oblast. Irrigation increases the number of microorganisms in the plowed layer and the layer beneath. Sprinkling has a greater effect on yield of agricultural crops and on microbiological processes.
对萨拉托夫州暗栗钙土耕层及下层采用不同灌溉方法对春小麦产量和土壤微生物发育的影响进行了研究。灌溉增加了耕层及其下一层的微生物数量。喷灌对农作物产量和微生物过程的影响更大。
