Acetylene reduction Nitrogen Nitrogen fixation Soybean Top-dressing
2009/8/6
Effects of (NH4)2SO4 top-dressing at the flowering stage to soybeans were investigated in view of its nitrogen fixation and assimilation. Possibility of estimating nitrogen fixation by time course mea...
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
2009/7/8
Nitrogen fixation by soybeans is reduced by high soil nitrate levels. This reduced nitrogen fixation capacity increases the dependence on soil nitrogen, which may result in depletion of soil nitrogen...
