In this chapter we are going to talk about the conservation of soil and its importance. What do you think if we first start by defining what soil is? Well, it is the material that is on the earth's surface, on which we can grow our food, where trees grow and without which we would not have where to plant. So that's why it's so important that we take care of it. Soil is not a resource that lasts forever.

One centimeter of it is formed in approximately 300 years. And if we don't take care of it, we can lose it until we have a completely eroded area that will be unproductive and will not be able to be used. This happens if we remove the plant cover to cultivate or build, which causes the soil to erode, the water to drain and not infiltrate.
1:02
To prevent that from happening in eroded lands, it is necessary to carry out some works of conservation of soils and waters in your lands, such as border sandstone, stone dams, material accommodation, among others. Consider that the works in your land should be worked in basins, or in other words, in the areas where the water flows to a single site.

Based on that, you will have to plan your works to counteract laminar erosion in ladders and erosion in craters and ditches.
1:34
Once you have chosen the land where you will do your work, it is necessary to make a tour with a technician to recognize the erosion problems you have in your lands, the different slopes and the materials. Once you determine the works you will do, you must measure the slope of the land for which there are different tools. Among the easiest to build are the A device and the hose level.
2:03
The A-app consists of three woods, two of two meters and one of one meter, a thread and a lead, which can be up to a stone. Calibrating it is very simple, as you can see. You point the two feet of the device and take the lead mark. You turn the device, take the lead mark again, and the center of both will be the level.

Now, the level of the hose is built with two 2-meter woods and a 14-meter transparent hose, like the ones used in albañilería. You have to fill the hose carefully so that no bubbles form and fix each end to a wood. Put the woods together at the same height and mark the level of the bubbles.
2:51
And so, ready, we have level. Another important point to consider is the material with which the area is counted for construction of the works. For example, if your interest is to make stone barriers in curves at level, and in your land there is no stone, this practice is not recommended.
3:11
Once the work that is going to be done is defined, it should start from the highest part to the lowest part, so that in a heavy rain, the works will resist more. We must know that the works that are built, in addition to helping us to take care of our soil, will also contribute to capturing water, with which the reforestations that are carried out will be more successful and the springs will contain more water for longer.

Muy bien, ahora sí estamos listos para conservar suelos, cuidar nuestros terrenos y arrancar con las obras necesarias para que no se erosionen más nuestro suelo. Así, también podremos captar más agua para nuestras plantas y manantiales.
