Form of nitrogen absorbed by plants
WebAmmonium (NH 4 +) and nitrate (NO 3 –) are the predominate inorganic forms of nitrogen in soils. Ammonium exists in exchangeable and nonexchangeable forms. Nitrite (NO 2) and nitrous oxide (N 2 O) are … WebPlant Nitrogen Needs and Uptake. Plants absorb nitrogen from the soil as both NH₄⁺ and NO₃⁻ ions, but because nitrification is so pervasive in agricultural soils, most of the nitrogen is taken up as nitrate. Nitrate …
