Soil texture refers to the relative proportions of sand, silt, and clay particles in a soil sample. These particles impact the physical and chemical properties of the soil, including its ability to hold water and nutrients, its drainage capacity, and its workability for agriculture. Soil texture is an important factor in determining the suitability of a soil for various uses, such as farming or construction. Researchers in this area study the composition, structure, and properties of soil particles to better understand how they influence soil quality and productivity. They may also investigate how soil texture changes over time due to factors such as erosion, weathering, and land use practices.
