Welcome, dear readers who are passionate about scientific content with practical contributions at a social, environmental and economic level. The present publication is directed to the study of soils, their permeability and the supply of nutrients according to the capacity of water they can absorb.
In order to introduce the reader to the study of this process, we will rely on research developed from the University of Granada in Spain, where they have currently managed to establish technological processes to monitor and predict the flow of water through simulations that allow to address the growth of different items in these plantemos.
The team of scientists who carry out this project, have managed to establish clear criteria to achieve the development of healthy and more nutritious vegetation based on proper hydration of soils, allowing the reduction of the amounts of water used in a conventional agricultural process, while establishing to have achieved a lower demand in the amounts of nitrous dioxide that affects our planet through the phenomenon of the greenhouse effect.

As Jesús Fernández Gálvez, professor and active researcher of the project, puts it:
"The proper management of water resources in the soil, generates a sustainable agriculture, where simulation processes allow us to predict the properties of storage, distribution and transmission of water in the porous cavities of our soils".
Through the simulators associated with soil functioning, these have focused on water conductivity, addressing variables of establishment, saturation and over-saturation, which respond to the amount of water that soils possess, hence the results yielded by the researchers show that those soils where irrigation is exaggerated, causes economic losses, in the first instance by the amount of water used and secondly, because the soil becomes unproductive, since they do not have the capacity to drain the excess water that has been injected by natural processes or by risks of the hand of man.
On the other hand, when we manage to establish an adequate saturation of the water resource, we could think that we are facing ideal conditions, however the reality is different, and the results allow us to establish that in saturated soils the roots of the plants decrease due to the lack of oxygen that circulates around them.

In this sense, the hydric establishment generates an ideal condition, if you will, where the porous capacity of the soil, being half empty, provides the flow of gases and nutrients needed in the root area, which favors vegetative growth.
At this point, the information provided represents a suitable alternative in agricultural areas, where perhaps we abuse the use of water resources due to ignorance in many cases of the water capacity of our soils.
