Methods Used In Countering The Issue Of Soil Erosion.
Soil erosion is the ununiformed displacement of the soil’s top most layer. It is normal for soil to be displaced at any point. Erosion however can seem to be a slow process and can be continuous without notice. Cause for alarm comes in when soil erosion makes a lot of damage.
Every time soil is formed, cut or exposed, there is usually a risk of soil erosion from the agents of soil erosion. When this is left unattended to, either naturally or artificially, the results could be tragic to that particular environment but when noticed and attended to, there would be little or no damage. Both human and natural activities can cause soil erosion.
Human activities that may lead to erosion include deforestation, excessive tillage on a single land for a very long period of time and even construction. There are two main natural causes of soil erosion. Soil erosion is enhanced by certain things. They are.;
The feel of soil. When soil particles are heavy and big, it is hard for them to be eroded.
Ground levelness has a great effect if soil will or will not be eroded. Steep lands makes it easy for erosion to occur.
Excessive use of soil makes it easy for it to be eroded.
The amount of rain n area receives will dictate the amount of erosion that will occur there.
The presence of trees in an area makes it hard for wind to blow there. When there is excessive deforestation, this makes it easy for the wind to displace soil.
Soil erosion has very serious effects on land both where it displaces to the point the displaced soil is deposited known as on-site and off-site effects respectively. On-site effects includes the degradation of soil nutrients in that particular area and also decrease in productivity as rich soil is taken away. Off-site effects could include blockages of drainage systems depending on the amount of soil deposited, the destruction and damage of roads and even housing among other features and could also mean that the new land becomes rich in nutrients.
One has to know what causes soil erosion in order to deal with it. People deal with soil erosion in the following ways.;
Ensuring that there is a lot of vegetation on land. Moving crops from one area to another helps soils retain fertility and avoids being loose. Learning that many trees can prevent excessive winds from blowing is a major boost of preventing soil erosion.
For water erosion, one of the main control measures that can be taken is the construction of gabions and other. Technology has enhanced the prevention of erosion by providing some products that counter the effects of erosion. Grass enforcement and plantation of artificial grass that do not leave the soil exposed. Collaborative measure in the universe help in dealing with erosion.
