What is soil conservation?

From the pages earlier, we learned about the role of soils and how essential they are for life on earth. Unfortunately, soils are under threat in many ways, from excessive farming practices, use of chemicals during agricultural practices, water, land and air pollution, erosion and so on. These upset the natural function of soils and affect many ecosystems that depend on it for survival.

This is why soil conservation is very important. It is the process or activities we can do or apply to our use of soils and lands to ensure their sustained health and quality.

Here are a few:

Planting vegetative cover:

how plants conserve soils

The root systems of vegetative cover holds soils in place and prevents wind and water erosion. It also ensures its supply of organic matter from dead leaves and dropping of animals waste. Vegetative cover also shelters the soils from excessive heat form the sun. It helps to reduce evaporation and retain soil moisture, needed for the breakdown of organic matter.

Careful waste disposal and management:
When we recycle more and compost our food waste, we reduce the amount of contaminants that we introduce to soils. We also give back to the land, rich humus from composts that we do. This is why we need to manage our waste well to ensure that our soils are alive and healthy.


soil conservation farming methods
Farming practices:

No till farming, terrace and contour farming are all great ways to conserve soil quality. Regarding no-tilling, crops are allowed to stay after the harvest season, to shed off naturally, thereby holding the soil together and sheltering the soils from wind and water action. Terrace and contour farms take into account the slope of the land to reduce run-off after the rains. In many places, wind breaks, usually composed of trees or shrubs planted along specific distances in farms are effective ways in controlling wind erosion.
