Determine phosphorus and calcium in soil of the grazing area, El-Khuwei locality, West Kordofan State, Sudan

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-khuweilocality, west Kordofan State, Sudan. The data was analyzed used a completely randomized design (CRD) with the effect of stages as thewhole plots and effects of sampling as the sub-plots. Sampling was done on two stages at the flowering and seed setting in selectedlocations (2km2 each), within each stage randomly selected and collected thirty samples of soil. (SPSS) Statistical Package for SocialSciences was used for the statistical analysis. The results indicated that growth stages were effect of macro minerals in the soilphosphorus concentrations and calcium concentrations in the natural range land was significantly difference (P<0.001) higherphosphorus P (0.15-0.10ppm) level at the flowering stage and leastphosphorus 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
