Soil and land managment Soil and Land Management The soil triplicity is graph that helps the person determine the type of soil they atomic number 18testing. This type of graph being a triangle has three sides. The first side, or skilful side is the percent of silt found inthe soil sample. The second side, or the bottom is the percent of sand found in the soil sample. The ternary 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. There 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 coat analysis we did Ithought was very confusing, and unnecessary. The view of the soil underneath the microscope wasnt very muchdifferent from the view without it, or at least I couldnt tell much difference. The two millimeter mark on the paperwas also very confusing. I had no idea of what I was doing during the particle size analysis. The mechanical soilanalysis was much more to my liking. I understood the whole process and loved the project we did with it. Fromthe begging when we went external to collect the soil samples to when we were finished waiting the 24 hours forthe water and soil particles to settle. After we mixed the right amount of dirt and water into the sample subway system wehad made 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 altogether that complicated.First soil begins as a rock and then is broken dependent upon the weathering factors. Soil types are based uponthe type of rock from which they are made. waver particles are further broken into various smaller sizes of rocksand minerals, then small floras such as lichens and mosses begin to grow on the rock surfaces. Dead plantma terials or organic matter are mixed with rock fragments, and as more organic matter is formed, larger plantforms such as ferns, grasses, and shrubs expunge root. After that process bacteria and fungi break down the organicmatter into simpler nutrients that are released into the soil, further aiding plant growth. The downside to this is that
