Abstract
The effects of source of phosphorus (P) (monocalcium phosphate or sheep faeces), degree of land slope, and season (autumn or spring) on plant uptake of P were investigated. During the relatively short time span of the trials (17 and 8 weeks for the autumn and spring trials, respectively), faecal inorganic P appeared to be less available to pasture than that from monocalcium phosphate. The proportion of P in the plants derived from faeces or fertiliser was little affected by degree of land slope or season.
