Prevention of Soil Erosion:

The prevention of soil erosion may also be referred to a process termed conservation of soil.

Recall that soil erosion is defined as a process that leads to the removal of topsoil through agents like water, wind, animals and human beings. The causes of soil erosion can be both natural and artificial.

Please read on an Introduction to Soil Erosion and Types of Soil Erosion here.

Soil conservation (or prevention of soil erosion) can be achieved via the following ways:

  1. Education of farmers on soil erosion and other agricultural practices.

    It is important to state that education is vital towards the development of every sector in a society. Without education, a farmer ends up lacking knowledge on soil erosion, let alone the means of preventing it.
    Please read on Illiteracy and Causes of Illiteracy here.

  2. Practice of terrace farming.

    Terrace farming can be implemented in hilly areas by cutting or creating 'steps' on the slope of a hill. It is typically practiced on sloped or mountainous farmlands, thus making farming possible on such lands. This is shown in the image below:
    Terrace Farming - Len Academy
    You can read on Problems of Agriculture in Nigeria here.

    The practice of terrace farming requires the use of steps typically referred to as terraces on a sloped, hilly or mountainous land. Whenever it rains, soil nutrients and plants are not swept along the slope; rather they flow to the next terrace.

    Note: Each terrace has an outlet through which water is channeled out.

  3. Avoidance of overgrazing on farmlands.

    Overgrazing is a process whereby herbivorous animals excessively feed on grasses, crops and other kind of plants to an extent that exposes the topsoil.
    Please read on the Differences between Plants and Crops here.

    The end result of overgrazing is an exposure of the topsoil to agents of erosion like water and wind.

  4. The planting of trees should be encouraged. This process (of planting trees) is referred to as afforestation and such trees acts as windbreaks.
    You can check out various Agricutural Terms and Meanings here.

  5. Land tillage should be carefully done. It should also be reduced to its barest minimum.

    Tillage refers to the agricultural preparation of farmland (to be planted upon) by various mechanical techniques like, digging, mixing, stirring and overturning via the use of instruments like shovels, axe, rake, hoe and so on.
    Please read on various Agricultural Tools and their Uses here.

  6. Practice of strip cropping.

    Strip cropping refers to a farming method whereby grasses (or other small crops) are planted on farmlands in a long partitioned rows; typically at right angles to the direction of the prevailing wind, or in line with the natural contours of the farmland so as to prevent wind and water erosion.
    Please read on the Causes of Soil Erosion here.

    In strip cropping, grass strips are planted between ploughed lands. This is shown below:

    Please read on Agricultural Land and its Uses here.

  7. Implemention crop rotation on farmlands.

    Crop rotation is a farming system whereby different crops are grown on the same piece of land at different intervals over a long period of time.
    You can read on Agricultural Pest and Crops Attacked here.

    Note: The continuous planting of one type of crop (termed mono cropping) on a piece of farmland will result in the loss of soil nutrients on such farmlands. This is true because soil whose nutrients are lost cannot support the growth of plants. As a result, the soil becomes exposed to water and wind erosion.

  8. Planting of cover crops on bare soils. This is shown below:
    Cover Crop - Len Academy

    Cover crop refers to grasses, legumes or (small green plants) that are grown prior to a planting season in order to protect the soil (for the new planting season).
    Please read on Asexual Propagation in Plants here.

    Farmers are encouraged to plant cover crops prior to a planting season. This is important because cover crops aid in maintaining soil structure by protecting the topsoil, thus preventing an exposure of the topsoil from the agents of erosion.

    Note: Cover crops acts as shelterbelts when planted on exposed soils.

  9. Use of runoff pipes and specialized chutes to direct excess water away from farmlands.

  10. Building of dams to prevent flood.

  11. Creation of embankments along the banks of the river in order to protect agricultural lands from being flooded.

Amazing facts in Agricultural Science

Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments 🤔

Squirrels do plant more 🌲 trees 🌲 (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them 😁

🐄 Cows 🐄 have got the ability to walk up stairs, but not down stairs

A group of cows 🐄 🐄 🐄  is called a team, drove or herd.

People just prefer to call them herd

NOTABLE POINTS IN Agricultural Science

There are about 630 different kinds of carnivorous plants.

Carnivorous plants are plants that derive some or most of their nutrients by consuming small animals, especially insects.

Carnivorous plants are also referred to as insectivorous plants.

Some example of carnivorous plants include sundew and Venus flytrap.
