PREPARATION OF SOLID FERTILISER BASED SOLUTION FERTILISERS UNDER GRASS ROOTS FIELD CONDITIONS

The aim of this work was to examine the preparation of mixed fertilizer solutions based on cheap solid fertilizers available in the market, where the solutions would be prepared on the farm site with limited facilities under “grass roots” field conditions, with minimal mixing. Urea, ammonium sulphate, phosphoric acid and potassium chloride (white, suitable for fertigation) as N, P, and K sources, respectively, were examined for the preparation of clear liquid solutions.
