  • Understanding nitrogen in soils

     · Plants can absorb NH 4 + -N. Also, because ammonium has a positive charge, it''s attracted or held by negatively charged soil and soil organic matter. This means that NH 4 + -N doesn''t move downward in soils. Nitrogen in the NH 4 + -N form that isn''t taken up by plants is subject to other changes in the soil system.
