Availability of phosphorus for lowland rice evaluated by the methods of Mehlich and ion-exchange resin in waterlogged soils

, : Availability of phosphorus for lowland rice evaluated by the methods of Mehlich and ion-exchange resin in waterlogged soils. Revista Brasileira de Ciencia do Solo 10(1): 45-50

An experiment was carried out in greenhouse conditions using surface samples of eight soils from the Careacu and Bela Vista polders in Minas Gerais State, Brazil. The soils were air dried, passed through a 2 mm sieve and packed in five liter pots. Two phosphorus treatments were applied (0 and 800 mg/pot of P2O5), to determine the phosphorus response by rice under waterlogged conditions after 70 days of growth.
