Soil Color Collection


Soil Color Collection


The soil can have different colors, such as red, black, yellow, white, gray etc. This diversity of colors depends both on the source material of the soil, as well as its position in the landscape, the content of organic matter and mineralogy, among other factors. The color is very relevant when differentiating the soil horizons within a profile and assist in its classification. In more scientific field studies, pedologists use the comparison of a soil sample with the standardized reference, which is the Munsell color chart.


Objective

           The purpose of the Soil Color Collection is to enable students to have contact with the numerous  colors that soils have and classify them according to Munsell's color reference.


Necessary materials


- Munsell color catalog

 - Different types of soils (in dry and sieved samples)



Set up


Place the samples next to each other and order comparing with the Munsell color catalog.

Goals

Identify the samples with the Munsell color catalog and classify the soils, relating their colors to their original materials, organic matter and mineralogy.

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

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. So then, what is dirt? Dirt is what gets on our clothes or under our fingernails. It is soil that is out of place in our world – w
