5 Soil Texture Sand What will sand do to the soil? It will improve the soil by improving the water infiltration and aeration
6 Soil Texture Silt is the medium sized soil separated. Silt particles are silky or powdery to the touchSilt grains will not stick to one another just like sand grains.Silt is the best soil as it has the ability to hold large amounts of water in a form plants can use.
7 Soil Texture Clay is the smallest size soil separate. It is composed of tiny crystalsClay is formed by chemical reactions between weathered minerals to form tiny particle of new minerals.Clay will hold more plant nutrients than any other separate.Clay grains will stick to one another.
