Soil and republic managment Soil and Land Management The skank triangle is graph that helps the person gibe the type of soil they betesting. This type of graph be a triangle has three inclines. The first side, or right side is the percent of foul found inthe soil sample. The second side, or the bottom is the percent of sand found in the soil sample. The tercet side, orthe right side is the percent of clay found in the soil sample. You read the graph from right to left being silt, sand,to clay. in that respect are twelve different classes of soil. The classes are sand, loamy sand, sandy loam, loam, silt loam,silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay, and clay. The particle size analysis we did Ithought was real confusing, and unnecessary. The opine of the soil underneath the microscope wasnt very such(prenominal)different from the dupe without it, or at least I couldnt tell much difference. The two millimeter mark on the paperwas also ver y confusing. I had no idea of what I was doing during the particle size analysis. The mechanic soilanalysis was much more to my liking. I understood the livelong process and loved the project we did with it. Fromthe begging when we went outside to collect the soil samples to when we were finished waiting the 24 hours forthe water and soil particles to settle. After we complex the right amount of dirt and water into the sample tube wehad do two recordings of the percent of sand, silt, and clay. After that we took the readings over to the soiltriangle to determine the type of soil that we had collected. The way soil is formed is not all in all that complicated.First soil begins as a careen and so is at sea dependent upon the weathering factors. Soil types are based uponthe type of rock from which they are made. Rock particles are further broken into various smaller sizes of rocksand minerals, then small builds such as lichens and mosses begin to grow on the rock surfaces. Dea d rigmaterials or organic matter are coalesce with rock fragments, and as more organic matter is formed, larger plantforms such as ferns, grasses, and shrubs take root. After that process bacteria and fungus kingdom break down the organicmatter into simpler nutrients that are released into the soil, further aiding plant growth. The downside to this is that
