O ground it corresponds to the superficial layer of the earth's crust, being very important for the development of life on earth, as we take from it the necessary food for our survival.
Note that we use the soil not only for the production of food, but also as raw material for various constructions.
In addition, the soil has important functions, from storage and drainage and infiltration of water on the surface, being a fundamental component for the development of several ecosystems.
For this reason, proper management and soil preservation become essential tasks, as it is a resource non-renewable natural, that is, it is limited, and unbridled exploitation can cause many problems futures.
Federal Law 7867 of November 13, 1989, implemented in Brazil the “National Day of Soil Conservation” which is celebrated every April 15th.
The date alerts to the importance of this resource, so important for the development of life on Earth, as well as water, air, fauna and flora.
Composition and Types of Soil
Soil is a complex composed of minerals and organic matter arising from a slow process resulting from the degradation of rocks and the decomposition of various animals and plants.
There are several types of soil, resulting from the action of elements such as water, climate and relief. Thus, the main soil types, are classified into:
- sandy soil
- clayey soil
- Organic Soil
The Importance of Soil for the Human Being
In human life, the soil participates almost entirely because we take the food we need for our survival.
In addition, we use this resource in civil construction, that is, in the construction of houses, buildings, among others.
The Importance of Soil for Animals
For animals, as well as for humans, the soil is a very important resource for development, as it is from it that they take their food to survive.
The Importance of Soil for Agriculture
The soil is fundamental in the composition of the terrestrial ecosystem, as it is from it that plants get all the nutrients they need to develop.
Soil type is very important for plantations and agricultural development. In this sense, not all soils help plant reproduction. This is because there are soils poor in nutrients, which impede the development of flora.
To improve the environmental problems caused in the soil, sustainable food production through organic farming has been a good alternative.
You organic food they are produced by the absence of chemical products (pesticides, insecticides, chemical fertilizers). The most used agricultural system not only affects the soil, impoverishing it, but can also generate various diseases in human beings.
Ground pollution
THE ground pollution it can occur in different ways, and human action has been an important factor of degradation.
The fires, the logging, the development of pastures (for animals) or plantations and the contamination of water resources (water) generate several environmental problems, such as erosion, which directly affects the soil, unbalancing ecosystems.
Some important measures must be taken, for example:
- reduction of fires and the use of pesticides in agriculture;
- reforestation of certain areas;
- do not throw garbage and chemical products (usually caused by industries) in inappropriate places;
- separate the waste according to selective collect.
