WHAT IS SOIL? Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. It forms at the surface of land – it is the “skin of the earth.” Soil is capable of supporting plant life and is vital to life on earth. Soil, as formally defined in the Soil Science Society of America Glossary of Soil Science Terms, is: The unconsolidated mineral or organic material on the immediate surface of the earth that serves as a natural medium for the growth of land plants. The unconsolidated mineral or organic matter on the surface of the earth that has been subjected to and shows effects of genetic and environmental factors of: climate (including water and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time.

At the beginning there was only one student who started the research, in 2011 another 3 students joined us, constituting our group. Soil education is often forgotten in schools, or treated in a simple way, which can generate students disinterest. We will disseminate in this space the results of our research, guidance to teachers, experiments and exchange of experiences for soil education, after all it is a finite natural resource, as many others that must be respected and preserved. Beyond academic research we want to disseminate and make accessible materials and teaching methods that help teachers, students, and even other researchers in Soil Education. We will do this by addressing the subject of soil in a ...
