| Abstract: | Pot culture experiments for the investigation of methods of applicationof powdered rock phosphate were conducted on a red earth and a slightlycalcareous alluvial soil.The former is extremely deficiency in phosphaticnutrients,having a pH of 4.8,while the latter is a very fertile soil ofabout neutral reaction.Both soils received pretty supply of nitrogeneousand potassic fertilizers with following variations of phosphorus treatment.Rice was used as an indicating crop.(1)No phosphorus;(2)Superphosphate;(3)Powde... |
