EFFECT OF SEED PHOSPHORUS CONCENTRATION, SOIL pH, AND SOIL PHOSPHORUS STATUS ON THE YIELD OF WHITE LUPIN

Influence of <i>Bacillus megaterium</i>and pH on the solubility of Sokoto rock phosphate in soil

“…This could be attributed to decline pH values.Therefore it was shown that Soil pH is one of the determinant factor in the plant nutrient availability in the soil and this was seriously observed especially at 4 th weeks were the pH is within the range of 7.4-7.5 with the highest p availability in soil which may tend to favors' the activities of this organisms.This result contradicts the findings of Omar, (1998) who reported a greatest soluble phosphorus following inoculation with bacteria. The findings do not conform to the work carried out by Mullins et al (2001), who reported that P concentrations were not affected by soil pH.…”
