Mineral nitrogen is simply calculated by adding together the nitrate (NO3-) and the ammonium (NH4+) levels measured through standard chemical analysis.These forms of nitrogen are most important to land-users as it gives an indication of plant available N in the soil.
Over 98% of all nitrogen present in the soil is in an organic form (i.e. contains carbon in its molecular structure). Organic nitrogen cannot be taken up by the plant until it is mineralized by micr
