Note the various forms of N -:- 1. Ammonium (NH4+) cation in the soil solution and fixed in secondary clays 2. Nitrate (NO3-) anion in the soil solution 3. Organic N in the soil 4. Ammonia (NH3) gas (released to atmosphere) 5. NO, N2O, N2 gases (released to atmosphere) anion- nitrogen -:- it is not held by soil colloids and can be lost from the soil through leaching. However in well aerated soils (plenty of oxygen), most of the NH4+-N (applied for example as fertilizer) changes to the...
