Studies on a caribou silt loam at Presque Isle, Maine were conducted to determine the effect of stones on runoff, erosion and soil moisture. The three treatments consisted of a control, stones over 3.81 cm in diameter removed, and stones over 3.81 cm removed, crushed and reincorporated into the soil. Removing the stones increased soil and water losses over a 4‐yr period. Infiltration and soil moisture was decreased as a result of stone removal. Crushing and returning the stones resulted in soil losses similar to that obtained under normal soil conditions. During 1961–1964, 20 storms produced 75% of the total soil loss and about 55% of the total runoff.
