Lumps of dirt, also known as CLODS, are small, irregularly shaped pieces of soil that are usually found in agricultural fields. CLODS are formed when the soil is disturbed by plowing or other activities, and they can range in size from a few millimeters to several centimeters. CLODS are often composed of a mixture of clay, silt, and sand particles, and they can be difficult to break apart. CLODS can be beneficial for soil structure, but they can also cause problems if they are too large or too numerous.
