Yield Decline Trends of Eroded Ultisols in Owerri, Southeastern Nigeria: Maize Response to Artificial Erosion

Nnenna Nnannaya Oti^*

The artificial incremental removal of surface soil to varying depths to simulate erosion followed by subsequent evaluation of crop growth and performance under uniform management is a common agronomic technique to study erosion/soil productivity relationships. However, because its results tend to exaggerate yield decline rates it is being replaced ...

Yield Decline of Major Crops Induced by Erosion on the Ultisols of Owerri, Southeastern Nigeria: Maize Response to Natural Erosion

Nnenna Nnannaya Oti^*

Few studies have been made to quantify the yield decline trends of major stable crops induced by erosion (natural and artificial) on the ultisols of Southeastern Nigeria, it is known that erosion’s impact on soil productivity is crop, environment and soil specific. This paper reports an aspect of a larger body of research work conducted between 199...
