Agronomic measures is that vegetation is used, either alive or dead, in sufficient quantities to shield the soil surface from the direct impact of raindrops and to create a rough surface which will physically impede run-off and slow it down to non-erosive velocities. The role of agronomic measures n achieving soil and water conservation has immense importance. It is important to understand and disseminate the different soil management practices used to cultivate the soil and grow crops.
Agronomic conservation measures function by:
- reducing the impact of raindrops through interception and thus reducing soil erosion and
- increasing infiltration rates and thereby reducing surface runoff and soil erosion
