How do you make a bund?
Construct no wider and taller than 50 cm x 30 cm bunds, around the field. Make sure that bunds are well compacted and properly sealed, with no cracks, holes, etc. This will minimize water losses through seepage (particularly in sloping lands). Adjust the spillway height to 3−5 cm for storing the same depth of water.
Which soil is not suitable for bund construction?
From the experience, it has been found that bunds could stand well in shallow, medium and medium deep soils. In deep black soil, due to cracks in dry condition, the bunds fail.
How are bunds helpful in conservation of soil?
The stone bunds form a barrier that slows down water runoff, allowing rainwater to seep into the soil and spread more evenly over the land. This slowing down of water runoff helps with building-up a layer of fine soil and manure particles, rich in nutrients.
