Human impact on soil
The human impact on the soil, the human being is the most important element in life, as he influences everything around him, including the agricultural land and soil, he can affect the agricultural land and soil negatively or his impact can be a positive effect, so the human being can It harms the agricultural soil and can benefit it. As for the negative aspect, people may not care about education and they may do some wrong things that greatly help in the emergence of many negative aspects of it. The negative side.
How does man affect the soil
Humans can affect soil quality either in a positive way or in a negative way, the consequences of which will accrue to them in any case. Man works to expand in all fields, the most important of which is in agricultural reclamation in agricultural lands in order to preserve agriculture, and thus this is evidence of an increase in fertile soil in dry areas. Thus, it improves the quality of agricultural and non-agricultural soils, but on the contrary, man works to cut down forests and increase buildings, which affects the agricultural and non-agricultural soils, and thus eroding the soil and being affected by it.
positive effect
Man has a very big role to play in preserving agricultural soil, because he is trying hard to provide many of the needs that agricultural soil requires, and man was able to succeed in that and to preserve the soil and its fertility, as a result of many things that man does in order to preserve it, including The most important positive effects of humans on soil are:
- Protecting the soil indirectly by recycling waste and removing it from the soil, which reduces the impact of this waste on the soil, and preserves its fertility.
- The use of pesticides that help kill pests in the soil, which have negative damage to the soil, which increases crop production in the soil.
- Increasing the agricultural area and thus increasing the quality of agricultural soil and soil in general.
- Planting trees and exploiting their fruits and wood after a period of time.
The negative impact
Also, despite the positive role played by man towards the soil and its impact on preserving it, there are many negative effects that also affected the soil.
agricultural consumption
It is a stressful type of farming, and this stressful form is a kind of agricultural consumption, as the soil is weakened, the cultivation processes are irregular in it. If you plant the same crop in succession, the soil will become weaker. The soil loves variety constantly and likes to change plantings from time to time. Negatively affect the yield and thus affect the soil Soil can also be affected by the lack of proper aeration.
Forest trees cut down
The percentage of forest destruction and tree cutting has increased due to population growth. And work to evacuate forests and agricultural places, without paying attention to the environmental damage resulting from cutting down trees, as it is trees that give us clean air, and the presence of forests causes rain, so because of cutting down trees and destroying forests, human life and the environment are endangered.
Soil pollution:
Among the negative effects that occurred to the soil is its pollution, and this was the result of many wrong things practiced by humans, including the excessive use of pesticides that we talked about, whose role is basically to protect the soil from harmful insects, but in the case of excessive use It greatly affects soil health.
Summary of human impact on soil
Anyone can positively or negatively affect soil quality, which will have consequences anyway. If man weakens the soil, this results in less fertile soil that may be arable. In addition, the presence of felling types in forests causes natural disasters such as increased flood waters, increased soil erosion and efforts to increase earthquake rates.
