I componenti del TERRENO - Fase Solida, Liquida e Gassosa

The soil is not composed of 100% earth, but, to be fertile, it must have a precise ratio between its solid, liquid and gaseous components. The ideal soil must in fact be half composed of air and water.... counterintuitive, right? Today we will see the phases of the soil, from liquid to solid, passing through the gaseous one; in this way when your agronomy teacher asks you what the soil is composed of, you will know what to answer. The solid phase of the soil is essentially composed of minerals such as silicates and organic matter often stored as humus. The growth of crops depends on the liquid phase, which find their optimum between the field capacity and the permanent wilting point. Finally, the most obvious phase, that is the gaseous phase... did you imagine this was also important for fertility? #agriculture #soil #agronomist Subscribe to this channel to access the benefits:    / @agronomix_   SOCIAL: Instagram:   / agricoltori_e_simpatizzanti   Facebook:   / agricoltoriesimpatizzanti   Mail: [email protected] TrattoriWeb:    / @trattori_web   My website: filippoballardin.com Hi, I'm Filippo, a third year student of animal science and technology at the University of Padua.
