Regulation of nitrogen acquisition in vegetables by different impacts on autotrophic and heterotrophic nitrification

Xiaoqian Dan et al.

Summary: The study revealed significant feedback between vegetable N uptake and soil gross N transformation rates. Plant NO3- uptake rates were higher than NH4+ uptake rates, while NH4+ uptake still accounted for a portion of total N uptake. Additionally, heterotrophic nitrification rate was stimulated and played a significant role in NO3- production in plant treatments.

Maize Seedlings Prefer NO3- Over NH4+ Independent of pH Changes

Mengqiu He et al.

Summary: The study found that the uptake rate of different forms of nitrogen by maize is affected by soil pH, and maize generally prefers NO3- over NH4+. The longer residence time of NH4+ in acidic soil can explain the higher NH4+ and total N uptake rates. Maize planting can reduce the rate of autotrophic nitrification by prolonging NH4+ residence time, while the rate of heterotrophic nitrification is stimulated by maize plants.
