Abstract:
The application of FYM also maintained or increased phosphorus status of LTFE soils. In treatments of FYM (T₈, T₉), the status of phosphorus fractions increased. Available-P status of LTFE soil at Initial stage was low in category (< 28 Kg P₂O₅ ha^-1) in most of the treatments, after long run (20^th year) it was more decreased except in treatments which were received FYM (T₈ & T₉). Due to application of FYM available status of P₂O₅ in LTFE soil increased up to medium category (28-56 Kg P₂O₅ ha^-1) from low category. There were overall increased in Inorganic-P & Total-P status of LTFE soils, but status of Available-P was decreased, which might be due to calcareousness of soil, which fixed phosphorus that applied as a fertilizers and transformed it in unavailable form to the plant, because of this reaction, available status of LTFE soil decreased, except in treatments where application of FYM, full dose of P and biofertilizer were there due to chelating effect of organic material and solubilizing reaction of microorganisms which protect available-P form to fixed in unavailable form.
