Web15 dec. 2014 · Nitrates can be readily absorbed by the plant and do not need to undergo any further conversion, as is the case with urea and ammonium, before plant uptake. No acidification of the soil if all the nitrogen is applied as nitrate-nitrogen. Nitrates limit the uptake of harmful elements, such as chloride, into large quantities. Plants absorb nitrogen from the soil in the form of nitrate (NO3 ) and ammonium (NH4 ). In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed.
