It's true! This is because soil is made up of a mixture of organic matter, minerals, water, and air. The organic matter in soil comes from once-living materials, such as plants, animals, and microscopic organisms. As these materials break down over time, they contribute to the formation of nutrients that support plant growth.Pure chalk is white, but it may be stained with iron oxide or other impurities.
