The principle of this study was to investigate the effect of moisture regimes, FYM and levels of P carriers on phosphorus fractions status of loamy sand in vitro condition. Incubation study was carried out during 2017, in the Laboratory of Department of Agricultural Chemistry and Soil Science, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar. Treatments comprising of three levels of moisture regimes, three levels of phosphorus of two P carriers, two levels of FYM and five incubation intervals were evaluated under a completely randomized design (with factorial concept) with three replications. Available phosphorus content in soil was increased significantly with the application of FYM (10 t/ha) with P2 (2.68 mg P/100 g soil) levels of P and maintenance of moisture at W3 (25 % Available water capacity) level was found significantly higher as compared to without FYM. Available P increased up to 3rd DAI then decreased concerning phosphorus availability in loamy sand. Under the different forms of phosphorus, maintenance of W1 (100 % Available water capacity) moisture regime, FYM @ 10 t/ha and P level with 2.68 mg P/100 g soil increased the in Organic-P and Total-P up to 14th DAI therefor, scarcity of available P increased at initial stage. The concentration and contribution of each fraction to Total-P was in the order: Occluded-P < Al-P < Saloid-P < Reductant-P < Fe-P < Organic-P < Ca-P.
