Organic Carbon Status of Lowland Area of the Research Farm, Kano University of Science and Technology Wudil, Kano State, Nigeria

The upland soils of the Nigerian savanna zones are low in fertility and their agricultural potentials for sustainable crops production are low. One of the most important factors in maintaining long term productivity of soils of such nature and such environment is the improvement of their organic matter content. In spite of low content of organic matter in tropical soils, organic matter is probably the life-wire of agricultural production in tropical agriculture. Research work was conducted at Kano University of Science and Technology newly established Research Farm to evaluate the status of organic content of the lowland area of the research farm. Walkley-Black method was used to determine the organic matter content of the soil samples Twenty soil samples were randomly collected at different depth of (0- 15 cm, 15 – 30 cm) the particle size analysis indicated that the soil of the area is sandy loam and sandy loam texture. The lowest organic matter contents obtained from the area is 1.67% and the highest is 2.01%. The results obtained indicate that the level of organic carbon content in the area is generally low as compared to standard for ratings soil fertility in the Nigerian Savanna.
