Overview
This e-lesson is part of Crop Production Level 3, Learning Unit 4: Apply Mechanical Soil Erosion Control Measures, Learning Outcome 4.3: Proper implementation of suitable mechanical soil erosion control measures according to collected data and following procedures.
Did you know that soil erosion can be controlled by constructing structures on the field to reduce land slope?
Introduction
Soil erosion reduces soil fertility, which may lead to poor crop quality, reduced crop yield, and low income for farmers. The risk of soil erosion increases with steeper terrain.
Mechanical soil erosion control measures are designed to reduce land slope, control runoff and increase infiltration. When used with appropriate agricultural practices, these measures are effective in protecting cropland and reducing soil erosion.
Learning Objectives
By the end of this e-lesson, you will be able to:
- Identify mechanical soil erosion control measures
- Measure the slope of land using appropriate tools and equipment
- Correctly set contour and grade lines using appropriate tools and equipment
- Construct bench terraces and trenches as mechanical erosion control measures
