Soil Fertility Assessment of Research and Teaching Farm of Audu Bako College of Agriculture Danbatta, Kano State, Nigeria
The most important variables in the soil are the plant nutrient elements. But Savannah soils are known to be low in these variables. Laboratory study was conducted to evaluate the soil fertility status of Audu Bako College of Agriculture Research and Teaching Farm, aimed at assessing these variables. The results of this study shows that all the variables tested, which includes among others exchangeable bases, organic carbon, total nitrogen, available phosphorus and cation exchange capacity (CEC), were low due to high leaching and excessive volatilization, which could be arrested by some practices like mulching, application of more organic manure and supplementing with inorganic fertilizers.
