WHAT IS LAND DEGRADATION
Land degradation occurs when the topography of the soil is destroyed through the use of high end machinery, continuous tillage of a given piece of land and the effects of volcanic eruptions. The issue with land degradation and its effects on agriculture cannot be over emphasize.
When you enter inside a land you want to use for agricultural activities and the landscape is not uniform, it is the result of land degradation. Land degradation can lead to loss of soil nutrients. The effect of soil erosion is one major cause of land degradation. A land that is degraded will not be easy to make good roads within the farm settlement.
CAUSES OF LAND DEGRADATION
- Degradation of soil as a result of Erosion
- Continuous tillage of the soil definitely lead to land degradation and leaching which in turn leads to loss of soil nutrients.
- Continuous cropping activities on a piece of land leads to land degradation. This land degradation is a result of uprooting of farm produce, use farm machine, wearing away of topmost soil due to erosion.
Land degradation that is due to continuous cropping can be corrected through manuring, crop rotation, bush fallowing and the application of organic fertilizers.
4. Land degradation can be caused by Sedimentation which can lead to the land becoming either acidic, clayed or sandy in most cases.
EFFECTS OF LAND DEGRADATION
- Land degradation leads to poor crop yield
- Land degradation causes leaching
- Land degradation destroys the landscape for farming activities
- The implication of land degradation due to erosion causes loss of soil nutrient. When a land is degraded, it affects every agricultural activity on the land.
• 5. A degraded land is also very difficult to erect farm buildings
How to correct land degradation
- Land degradation checkmated by planting tall trees that can prevent wind erosion
- Planting of cover crops to prevent sheet erosion is one major way to correct land degradation
- The use of proper drainage system in the farm prevents soil erosion which would have led to land degradation.
- Avoid excessive use of large farm machines in order to curb land degradation
- Land degradation can be corrected by using terraces and bolds within the farm.
- Apart from using crop rotation, cover cropping and good drainage system to correct land degradation, it advised to always plan you land by surveying and taking soil samples be any farming activity.
For any farming or agricultural activities on a land, there are basic principles of agriculture that needs to be followed, in order to avoid land degradation, they are
