Scientists also measure different elements, corresponding to the quantity of water within the soil and the way it varies over time—for instance, is the soil unusually wet or dry? The tests can also identify contaminants and heavy steel within the soil and determine the soil’s nitrogen content and pH level (acidity or alkalinity). All of these measurements can be used to determine the soil’s health. Crop residue helps build organic matter in the soil, which helps water infiltrate and holds rainwater like a sponge.

The A horizon or topsoil is thus also referred to as the humus layer. The topsoil is the region of intense biological activity and has the most nutrients. Insects, earthworms, centipedes, bacteria, fungi, and other animals are discovered inside this layer. The humus makes the topsoil extremely porous, allowing it to hold air and moisture necessary for seed germination. Sand is composed of rock and a few minerals. This sand then combines with clay and silt to kind sandy soils. Silt forms equally to clay and sand by the erosion of rocks and minerals. Nevertheless, silt has a slicker really feel in comparison with sand and clay because of its uniquely formed particles, which come from mainly quartz and feldspar. Soil taxonomy refers back to the classification of soil types.
