Once nitrogen is fixed, it is subject to several chemical reactions which can convert it to different organic or inorganic forms. Mineralization occurs in soil as microorganisms convert organic nitrogen to inorganic forms.
Of all the essential plant nutrients, nitrogen is the one most often limiting to potato production on sandy soils. Nitrogen fertilizer recommendations for irrigated soils are based on crop yield goal and previous crop (table 3).he amount of nutrients removed by a potato crop is closely related to yield (table 1). Usually, twice the yield will result in twice the removal of nutrients. The vines take up a portion of the nutrients needed for production. The rest goes to the tuber and is removed with harvest.
