Soil test phosphorus (STP) finds its agronomic utility for the recommendation of phosphorus (P) fertilizer to crops and in risk assessment of offsite soil P movement from an environmental perspective. The aim of this research was to understand the influence of P from several P sources applied on Soil test phosphorus (STP) in 6 different soils both before crop P removal (NBP0) and after the first (NBP1) and seventh harvest (NBP7) of corn (Zea mays L.). The P was extracted with Bray1 solution from animal P sources alone as well as from soils amended with P sources. The results suggested that monogastric P sources contained relatively large proportions of Bray1 than ruminants. It is shown that all soils amended with turkey litter contained the least amounts of NBP0 and NBP1; The greatest proportion of residual P measured as Bray1P was seen in hog manure
