Sorghum was grown in pots containing fifty-one soils from the following families: Latosolic Reddish Prairie and Latosolic Brown Forest, Low Humic Latosol, Humic Latosol and Humic Ferruginous Latosol. Truog's and Saunder's "available" phosphates, the inorganic phosphate fractions and labile phosphate were determined in these soils, and each correlated with phosphorus uptake by the plants. Saunder's available phosphate assessments were significantly correlated with short-term phosphorus uptake values in all the latosolic soils and latosols. Phosphorus uptake was related to Truog phosphate status only in the soil families occurring under low rainfall whereas its relationship with L value was significant in the latosols. The correlation between iron phosphate fractions and phosphorus uptake increased as the degree of weathering of the soils increased but was significant only in the highly weathered soils. Calcium phosphate and aluminium phosphate fractions were each poorly related to phosphorus uptake. There was generally good correlation between total inorganic phosphate and phosphorus uptake. | |
