Distribution of Forms of Potassium in Soils Cultivated to Shea (vitellaria Paradoxa C.f. Gaertn) Trees at Bida, Niger State, Nigeria

OSAYANDE P.E.^*, P.O. Oviasogie, Orhue E. R., Udoh, J. J

The distribution of potassium forms was studied at Bida, Niger state as part of the Shea butter tree domestication effort of the Nigerian Institute for Oil Palm Research. Soil samples were obtained with the aid of a soil auger at 0-15 and 15-30 cm. The soil samples were air dried, sieved with a 2 mm sieve and analyzed for some physical, chemical an...

Phosphorus Status in Some Soils of Mid - Western Agro - Ecological Zone of Nigeria

Orhue E. R.^*, John Kingsley

The trial was carried out to determine the status of various forms of P in soils formed on 3 types of parent materials in Southern Nigeria. Soil samples were obtained from3 ha area in each of the locations at 0-15 cm and 15-30 cm depth and then subjected to routine physical and chemical analysis. Results revealed that the sand component of the soil...
