What are the different properties of the soil horizons?
Soil is composed of three main categories of particles: sand, silt, and clay. Each of these particles has distinct properties including its feel, texture, color, nutrients, and size. While these three particles can form many different combinations in a soil , the proportion of each changes in each horizon. In this experiment, you will take a soil profile and determine the properties of three different horizons. Because the depth of each soil horizon depends on location, the depth suggested to dig is a guide. You may need to dig farther down than suggested to find three unique horizons, or you may not have to dig as deep. Once you have the three samples you will examine their characteristics in several ways. Using a kit, you will test each sample…
