Description In recent years, scientists and extension agencies have become much more aware of the
high potential productivity of Vertisols and associated soils. However, one gap in
current knowledge is how best to assess the phosphorus status of these heavy black
clay soils. Crops on Vertisols have appeared to be less responsive to phosphorus
fertilizers than those grown on other soils. This difference has been explained by
various hypotheses, notably high fixation of fertilizer phosphorus and poor prediction
of soil-available phosphorus by the Olsen test. As yet no hypothesis has been unanimously
accepted. Part of the difficulty lies in the fact that much of the information is
scattered. By bringing together scientists who have actually studied some aspect of
phosphorus in Vertisols, this workshop aimed to develop a better understanding of
past work and future research needs.
