Forest Soils
Forest soils, where soil formation has been influenced by forest vegetation, are generally characterized by deeply rooted trees, significant ‘litter layers’ or O horizons, recycling of organic matter and nutrients, including wood, and wide varieties of soil-dwelling organisms. There are also soils now covered with forest vegetation, often plantations, on lands that were not naturally forested. These soils are probably undergoing processes that give them ‘forest soil-like’ characteristics, e.g., litter layers from trees, woody organic residues from deep roots, and associated soil microbe and fauna populations. Like other soils, forest soils have developed, and are developing, from geological parent materials in various topographic positions interacting with climates and organisms. Forest soils may be young, from ‘raw’ talus, recent glacial till or alluvium, or ‘mature,’ in relatively stable landscape positions. Just as forest vegetation of the world varies greatly, so do forest...
The birth of our project
Hello guys! Starting the activities of this blog, nothing more fair than a presentation about who we are and what we want! The research project on Soil Education, started in the Department of Geography of USP, under the initiative of Prof. Dr. Déborah de Oliveira in 2010. 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 ...
