Determine Phosphorus and Calcium in Soil of the Grazing Area, El-Khuwei locality, west Kordofan State, Sudan

Abstract

A two stages flowering and seed setting field experiment was conducted to determine of some macro minerals in soil phosphorus P and calcium Ca in the natural range land, during 2011 in El-khuwei locality, west Kordofan State, Sudan. The data was analyzed used a completely randomized design (CRD) with the effect of stages as the whole plots and effects of sampling as the sub-plots. Sampling was done on two stages at the flowering and seed setting in selected locations (2km2 each), within each stage randomly selected and collected thirty samples of soil. (SPSS) Statistical Package for Social Sciences was used for the statistical analysis. The results indicated that growth stages were effect of macro minerals in the soil phosphorus concentrations and calcium concentrations in the natural range land was significantly difference (P<0.001) higher phosphorus P (0.15-0.10ppm) level at the flowering stage and least phosphorus P level at the seed setting stage respectively, also growth stages were effect of calcium Ca (110.22-99.75ppm) level was higher calcium Ca level at the flowering stage and least calcium Ca level at the seed setting stage respectively.
