What is the name for the top layer of soil that’s packed with nutrients and organic matter?
Correct Incorrect Topsoil is the richest soil layer, made up mostly of decomposed organic materials like plants and animals, which makes it vital for plant health. Although it’s only a few inches thick, topsoil plays a major role in farming and gardening. Since it can erode over time, farmers and gardeners use methods like crop rotation and cover crops to keep it healthy and prevent loss.
