What is soil erosion and what are the causes of soil erosion?

Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

What are some soil conservation methods?

4 Types of Soil Conservation

  • Why Soil Conservation? Good soil conservation helps to put nutrients back into the soil.
  • No-Till Farming. Farming land without tilling, or no-till farming, is something soil conservation professionals recommend.
  • Crop Rotation and Cover Crops.
  • Windbreaks and Stream Buffers.

What is meant by soil conservation?

Soil Conservation is a combination of practices used to protect the soil from degradation. This means returning organic matter to the soil on a continual basis. Soil conservation can be compared to preventive maintenance on a car.

What are aims of soil conservation?

Soil conservation practices are those farming operations and management strategies conducted with the goal to control soil erosion by preventing or limiting soil particle detachment and transport in water or air.

What is mechanical soil conservation?

The objective of mechanical soil conservation strategies is to protect the soil from the impacts of heavy rain and wind and prevent soil erosion. Soil conservation will help to maintain nutrients and structure, which will contribute maintaining the crop yield under stable conditions.

What is soil degradation and conservation?

Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.

What are the strategies to reduce soil erosion and preserve land?

You can reduce soil erosion by:

  • Maintaining a healthy, perennial plant cover.
  • Mulching.
  • Planting a cover crop – such as winter rye in vegetable gardens.
  • Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
