1. Efficiency of soil and fertilizer phosphorus use : reconciling changing concepts of soil phosphorus behaviour with agronomic informationJohn Keith Syers, A.E. Johnston, David Y. Curtin, 2008 Opis: The efficient use of phosphorus (P) is essential to many agricultural and environmental issues. This bulletin reviews, analyzes and synthesizes information on the efficient use of soil and fertilizer P. It presents information on the plant availability of soil and fertilizer P, with an emphasis on soil plant interactions. The focus is on the changing concepts of the behavior of both soil and fertilizer P and on the need to define and assess their recovery and, thus, P-use efficiency more appropriately.--Publisher's description.
