Runoff & Soil Conservation on Maize Growth in Ile-Ife, Nigeria
These techniques are able to control runoff and erosion. The Contour bunds system consists of semi-circular earth-bunds embankments constructed along the contour lines. The Infiltration pits are trenches dug along the row of the plant-stand, filled with grasses, plant residue, stubbles or stover and covered back by a thin layer of soil. The mulched plots involves covering of the soil with crop residues and leftovers on the field and dried grasses. The Tied-ridges consists of earth ridges made across the slope.
