Adepoju, A.Y. | Afolabi, F.A.
Surface soil materials from 12 sites were each incubated with a known quantity of P for 6 weeks, after which the availability was estimated using 5 different chemical extractants. The soil were then cropped in the greenhouse to determine actual plant P removal and to correlate the chemical test values with total plant P removal.
