dc.description The authors discuss organic matter is soil, how in grass lands the content of such is higher than none and the increased need for cropping, tillage and management treatments are needed in order to effect any measurable changes.In semi-arid regions on their fields, wind erosion may be serious concern. Stubble mulching may be helpful in addressing this. This article discusses the effects of stubble mulching and conventional tillage on soil properties and the the changes, if any, in their soil properties. the soil properties that were measured in this study were organic carbon, total nitrogen and bulk density. The rebuilding of soil organic matter levels in cultivated soils under dry land agriculture in the studied area was deemed a very slow process. The differences in organic mater level of the moderately course-textured soils between the two system will widen under certain management systems. The opportunity for erosion is much greater under the conventional tillage than under stubble mulch. the productivity of the conventionally tilled fields is already lowered. Thus, the amount of the residue returned will be lower than be returned to the stubble mulched fields. On fine textured soils, the total nitrogen content was higher in stubble mulched than conventionally tilled fields. Bulk densities were higher on crop land than grass lands. The largest difference was on moderately coarse textured soils. On these, the bulk density was higher than on grass land. No difference in bulk density existed between the stubble mulched and conventional tillage crop land. The outcome of soil organic matter equilibrium level can be altered by tillage practices and that erosion control with stubble mulching over conventional tillage management is a major factor contributing to the difference of the level.
