Yes, you can stop soil erosion on your farm

The first measures of soil erosion control involves good agronomic practices that include contour ploughing, surface mulching with crop residue which will protect the soil against rain drops impact and also slow down surface runoff, planting grass strips that will hold eroded soil and slow down the surface runoff. Terraces Second, is using conservation structures where surface runoff is very high and would cause serious damage to the land. The recommended structures include terraces, cutoff drains and waterways. Terraces will protect soil from being eroded.

Cutoff drains and waterways have to be designed and constructed for safe disposal of excess runoff during heavy rains without causing further erosion. Third, are gully erosion control structures where there has been severe erosion due to high volumes of surface runoff. Gully erosion control The aim of gully control structures is to reduce the velocity of surface runoff in the gully channel to control further channel erosion and enlargement of the gully, cause deposition of the eroded soil in the gully which will finally fill up and vegetation established. Gully control structures are referred to as check dams which can be constructed using locally available vegetation and woody material or stones. They are designed and constructed starting from the top end of the gully and working downwards to the whole length. They have to be properly spaced for effective control of runoff velocity in the gully. There are cases where gullies can be effectively controlled and be put back into production again. Measures should be put in place to allow more rainwater infiltration into the soil profile and minimise surface runoff accumulation. Every gully has a catchment from where surface runoff accumulates and flows into defined channels which enlarge to form big gullies. Maintaining vegetation cover and applying good agronomic practices as described above will reduce the volume of surface runoff into the gully. [email protected]]
