Tian, J., Boitt, G., Black, A., Wakelin, S.A., Chen, L. and Condron, L.M. 2017. Accumulation and distribution of phosphorus in the soil profile under fertilized grazed pasture. – Agriculture, Ecosystems and Environment 239: 228-235.
The fate of P from long-term fertilizer inputs to the soil is of great economic and environmental concern but remains poorly understood. This publication discusses how sequential fractionation was used to investigate P accumulation and distribution in the soil profile to 100cm and its results. Findings indicated that P applied in excess of agronomic requirements and soil retention capacity was transferred below the topsoil and root zone by leaching.
