Soil Texture Analysis Background Information: For those people who depend upon the soil, the ability of that soil to hold water and resist erosion are concerning factors. Soil texture refers to the ratio of different- sized minerals in the soil. Based on size, mineral particles are referred to as clay, silt, and sand. Clay particles are small and electrically charged, so they attract and hold water molecules. Thus, it is important that soils used to grow crops have some clay content. Clay also helps make soil resistant to erosion. Like clay, silt particles are also small enough to hold water in the soil. But exposed silt washes away easily, taking nutrients with it. A soil with too much sand content allows water to pass through very quickly and does not hold enough moisture to support most plants. Exposed sandy soils many be subject to erosion if the angle of the land, the slope, it too severe. Objective: In this lab you will determine the texture of a soil sample.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
