    Abstract/Description
    The initial effectiveness of two rock phosphate samples from Morocco (MRP) and North Carolina (NCRP) was compared with concentrated superhposphate (CSP) in greenhouse using two Alfisols and one Ultisol from southern Nigeria. Under similar pH condition (pH 6), the two rock phosphates were more effective P sources for maize plant in the two Alfisols than in the limed Ultisol. The relative effectiveness of the three P sources followed the order of CSP>NCRP>MRP. A larger portion of rock P (Ca‐P) applied to soils was transformed into Al‐P and Fe‐P from NCRP source than from MRP source after 90 days.
