DOI: 10.1007/s11104-018-03918-6
Abstract: AimsCereal can stimulate legume N fixation through competition for soil mineral N. In addition, organic acids in the rhizosphere can mobilize external nutrients, which may help nodulation. However, how much NO3− and NH4+ competition and… read more here.

DOI: 10.1186/s13007-019-0473-1
Abstract: BackgroundThe primary sources of nitrogen for plants have been suggested to be nitrate (NO3−) and ammonium (NH4+). However, when both nitrate and ammonium are simultaneously available to plants, it is very difficult to differentially quantify… read more here.
