Maize uptake ammonium and nitrate
Web1 jun. 2024 · 1. Introduction. Nitrogen (N) is a key mineral nutrient for plant growth and development. For most higher plants, NH 4 + and NO 3 − in the soil solution are the two major inorganic N forms for plant absorption (Miller and Cramer, 2004).Their uptake and metabolism depend upon the presence of water and its mobility in the soil because NH 4 … Web1 mei 2024 · To investigate this effect, we performed a pot experiment with maize in slightly acidic soil (pH 6.9) with one water-soluble (triple superphosphate [TSP]) and two water-insoluble (sewage sludge-based and hyperphosphate [Hyp]) P fertilizers and an ammonium sulfate nitrate with or without a nitrification inhibitor (NI).
