Abstract
The possibility of using soil extractants to monitor the transformation of phosphorus (P) fertilizer on a Bungor series soil was investigated. Three soil extractants - Bray 2 Ammonium acetate lactate (AAL) and Olsen - were evaluated. The soil was treated with three levels of Peach from rock phosphate and superphosphate at 0 150 and 3000 kg P/ha no lime and limed at 4 tons/ha and P applications with a higher amount of P being extracted from the recent. These extracts were able to differentiate between the 150 and 3000 kg P/ha treatments but were not able to distinguish the forms of P. Olsen extractant on the other hand was able to detect the two P forms and showed P release from rock phosphate with time.
