In the process of retrieving soil moisture (Mv) by active microwave, surface roughness is an important parameter affecting the accuracy of mv retrieval.Using effective roughness to replace the origina...
Cultivar Differences in Dependence on Nitrogen Fixation of Soybeans in the Field with a High Soil Nitrate Level Determinated by the Relative Ureide Abundance Method
Cultivar difference High soil nitrogen Nitrogen fixation Nodule Relative abundance of ureide
