Max.P adsorption capacity ranged from 1250¿1834 µg g-1. Energy of adsorption varied from 0.223-1.00 µg ml¿1, P buffering capacity ranged from 139-243 and P saturation ranged from 0.27-1.59 µmol g-1. Acid although extracted the highest amount of both native and applied P, showed the poorest relationship with relative dry matter and P uptake by rice. The critical level for Olsen P was found 5 mg kg¿1 for the coastal soils of Bangladesh. Tidal floodplain soils, on an average of 12 samples, contained 887 mg kg-1 of total P of which only 0.01% remained in solution form, 1.84% in NaHCO3 extractable, 4.24% in NaOH extracted Pi fraction, 46.65% in NaOH Po, 28.19% in acid pool and 18.97% in residual pool. Continuous rice cultivation without P application, decreased the conc. of labile P, moderately labile P and stable P but with the addition of P increased the labile and moderately labile P. The labile P and stable P estimated through plant based approach explained the variability of relative dry matter yield of rice and P uptake better than the soil test approach.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659218613\"\u003e\u003ch3\u003ePhosphorus sorption, desorption, fractions and supplying capacity of tidal floodplain soil\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659218613","offer_id":39487718391901,"sku":"9783659218613","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b40242d2-8f0a-41ce-8d51-8e0ddc631c88.jpg?v=1776920344","url":"https:\/\/shop.autorenwelt.de\/products\/phosphorus-dynamics-in-trial-floodplain-soils-of-bangladesh-von-md-fazlul-hoque","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
