Detailed explanation-1: -Considered the most fertile of soil type, loamy soils are a combination of sandy, clay and silt particles. The clay and silt particles improve moisture retention while the sand minimizes compaction and improves drainage. Loamy soils don’t get dried out in the summer, but also don’t get water-logged in winter.
Detailed explanation-2: -The thick brown or black substance that remains after most of the organic litter has decomposed is called humus. Earthworms often help mix humus with minerals in the soil. Humus contains many useful nutrients for healthy soil.
Detailed explanation-3: -The topmost horizon is the ‘A’ horizon and, as we have noted above, is usually the darkest layer of the soil because it contains most of the organic matter. Here, remnants of plants and even animals are incorporated into the soil.
