Leaching and residual value of superphosphate and rock phosphate under high rainfall conditionsTools Bruce, R.C. (1968) Leaching and residual value of superphosphate and rock phosphate under high rainfall conditions. Queensland Journal of Agricultural and Animal Sciences, 25 (2). pp. 77-79.
AbstractLeaching of superphosphate and of rock phosphate ran fairly parallel. Residual phosphorus after 3 years from the application of 200 lb. P205 per acre was appreciable, but there was little retention from amounts of 100 lb and lower.
