Erosion can be a very great disaster to any farm and farm manager if it is not put into consideration when planning the farm landscape or if not properly managed. Aside the grievous effects it do have on the crop on the field, it causes a lot of harm to the farm land itself. Therefore, erosion prevention, control and management is very crucial for farmers to note when planning for the planting season or year.
Erosion can be very injurious to the crop especially at the juvenile stage, at this stage the plants get uprooted easily by wind or water pressure. Erosion can also cause weeds to the vegetation as it displaces everything along it path. It can easily introduce unwanted plants to the field of desirable crops. Hence erosion should be prevented, controlled properly.
There are many causes of erosion both natural and man-cause, either of these causes are very disastrous to the crop, farm land therefore it should be prevented and controlled
Below are ways of controlling erosion on the farm.
#1 planting of wind breakers.
One of the effective way of preventing erosion is by planting trees along its path. The trees serve as wind breakers, they help to reduce the speed and impact of the erosion on the crops and also reduce the amount of damages done on the farmland. For water erosion they help to slow down the flow of water and diver the water from flowing down hills. Examples of trees that can be planted are timbers and other tree crops. These plants also help to anchor the soil together.
#2 Practicing crop rotation.
Crop rotation is the planting of the different plants on the same piece of land at different period of time. The different crop has different depth which help to maintain the compactibility of the soil, some of the crops may serve as cover to the top soil which help to prevent run off and the soil from leasing. Crop rotation have serve as one of the most effective way of controlling erosion therefore it is advised to practice. Crop rotation is effective mainly against water erosion.
#3 Planting cover crop.
Another way of preventing erosion is by planting cover crops on the soil. Cover crops are leguminous creeping crop on the soil surface. They are usually grow creeping on the soil surface thereby help to cover the soil from being eroded. They prevent the washing away or leasing of the top soil nutrients. Example is melon.
#4 Shifting cultivation.
Another way of preventing erosion is shifting cultivation, this is when a piece of land is left uncultivated for a particular number of year after it has been previously used to regain it used or lost fertility. When the land is left to fallow it help it to regain its fertility used over the years. One if the causes of erosion is continuous cropping, it makes land become bare thereby exposing it erosion and leashing easy. But the land is left to fallow, it revegetates and regains it lost fertility.
