What kind of ploughing could help minimise erosion on these slope?

Contour ploughing is a technique that could help minimise erosion on slopes. This involves ploughing along the contour lines of the land, rather than up and down the slope. This helps to slow down the flow of water and reduce the risk of soil erosion. Additionally, using cover crops or planting vegetation on the slope can also help to stabilise the soil and prevent erosion.

Contour Ploughing

Contour ploughing involves ploughing along the contours of the slope, rather than up and down. This creates small ridges that run perpendicular to the slope, which help to slow down the flow of water and prevent soil erosion.

Other Techniques:

Terracing: Building terraces on the slope can also help reduce erosion by creating level areas that break up the slope and reduce the steepness.

Mulching: Applying a layer of organic matter, such as straw or wood chips, to the soil surface can help slow down erosion by protecting it from the impact of raindrops and wind.

Cover Crops: Planting cover crops on bare slopes during the off-season can help protect the soil from erosion and improve soil structure.

Vegetative Barriers: Planting shrubs or trees along the contours of the slope can create a vegetative barrier that helps to intercept runoff and reduce erosion.
