Question

why should be done to prevent the buns on a farm getting washed away in the rainy season

Answer 1

When you bund the drains or loe lying areas, you have to either insert stones and enclose the stones with a strong wire mesh, stones should be stacked of various sizes depending on the length of the bund or the amount of water and the velocity of water flowing , if not make the bunds with a larger base and tapering to the top and plant Vetiver grass , this roots of the grass grow deep into the base soil and the roots also helps in binding the soil thus strengthening the bund
