Soil and Water Management – Grass Strip in Mango

Abstract

Grass strips are 1 m-wide strip of grass planted on terraces along contours to reduce the amount of water flowing down the slope and conserve soil. This technique can be practiced in wet and moist areas. Grass strips are planted with fodder grass such as napier or are left with natural grass, thereby providing fodder for livestock (cut and carry). Grass strips are widely used as vegetative barriers to reduce soil loss and increase infiltration and soil moisture. Due to increased soil moisture, there is more water available for the crops which leads to increased agricultural production. The grass is grown in alternating strips following contour lines. Depending on the grass used, the strips may provide fodder for livestock as well. Compared to other interventions grass strips can be easily crossed by oxen and ploughs. Grass strips can filter sediment, evacuate excess runoff, and can also withstand inundation. They may ultimately form into bench terraces.
