Contents and Distribution of Phosphorus Forms in Some Haplic Plinthaquults in Bauchi Local Government Area, Bauchi State, Nigeria

Abstract:
Studies were conducted to determine the contents and distribution of forms of phosphorus (P) in some Haplaquults in Bauchi Local Government Area (LGA) of Bauchi State, Nigeria. A total of 50 composite soil samples comprising five each of surface 0-15 cm and subsurface 15-30 cm samples were collected from each of five representative locations, namely: Luda, Bayara, Mun, Liman Katagum and Zungur, in the LGA. The soil samples were analysed in the Laboratory using standard procedures. The results indicated that the soils were mostly clay loam, slightly acidic (pH = 4.8-6.6) and low to medium in organic carbon (1.8-12.0 g kg-1). Except for Al-bound (CV = 22.15%) and reductant soluble Fe-P (CV = 37.75%), all the P forms were fairly uniformly distributed in the locations studied. Although both location and depth did not significantly (p>0.05) influence the distribution of the P forms, the contents followed the order: total P>Fe-bound P>Al bound P> occluded Fe-Al-P> reductant soluble-P> Ca-bound P> available P. The results also indicated that sand fraction significantly (p<0.05) and positively correlated with Ca- and Al-bound P. Improving the drainage condition of the fadama lands and liming are recommended to improve the organic matter mineralization and reduce P fixation, hence, increase the availability of P in the soil.
