    The strength/power of the soil to provide vital nutrients values(nitrogen, phosphorus, and potassium) to the plant’s roots, keeping it fresh and alive is known as soil fertility. When there is agricultural production, the ground needs to be solid and in check. Fertile soil also plays a major role in retaining moisture and maintaining the apt pH value. If the soil underneath the crops is not in the right state then that might hamper the entire farming.

    Whenever the soil fertility components get tampered, and essential elements are taken away from the soil, without making efforts for its re-establishment, depletion of soil fertility occurs. It is the removal of nutrients and essential components of the soil from itself.


    The major causes of soil fertility are listed below:

    1. Inadequate fertilizer use

    2. Total removal of crop and inadequate cropping methods

    3. Non-efficient methods of crop rotations

    Methods through which the soil fertility can be conserved:

    1. Protecting the topsoil by planting trees on left-out spaces of fields.

    2. By implementing crop rotation, through which many different types of plants can be planted on the same field.

    3. No-tilling.

    4. Stopping to dig unnecessarily in the field.

    5. Creating a compacted soil surface.

    6. Planting more and more indigenous crops.

    7. Adding organic material to provide additional richness.

    The technology is working very hard for improving soil fertility. These include:

    -nutrient management

    -crop residue management

    -applications of chemical fertilizers


    Thus, we as citizens of India should work collectively and prevent our soil from losing its rich nutrient values.

    Soil depletion or erosion is the process by which the topmost fertile layer of the soil is removed due to any physical impacts such as wind water or any animal. Due to this process the soil loses it’s nutrition. It also takes place due to some of the human activities such as deforestation. It can be said that Deforestation is the major problem that is causing erosion . People cut trees for there needs due to which the roots leave the soil and phenomenons like floods and landslides take place.Even agriculture causes soil erosion as for agriculture tress are removed and seeds are sowned in the on month of spring with causes it be barrened in the months of winter. Grazing of animals like sheeps and cows also also causes soil erosion as while grazing they remove the plants from there roots. For construction of buildings tractors are been drove in order to level the ground causing the fertile soil to get eroded.
    There are various impacts of soil erosion. The soil looses its nutrients while effects the growth of the crops. It also causes natural calamities such as earthquakes and landslides.
    There are ways in which soil can be prevented from eroding. The soil should not be left barrened instead grasses and shrub should be grown on the land. Keep the drainage system of you building our house clear so that the wasted water is not gone to the garden as the overflow of water can cause erosion. Do not over water the plants. The older plants which have the roots attached to the ground are more helpfull in controlling the erosion than the plants which are new and there roots are not very strong. Fertilisers and nutrients should be added to the soil in order to maintain it’s nutritive value of the soil so that it can give rise to a healthy plant.
