CLARENCE M. WILSON, ROY L. LOVVORN, AND W. W. WOODHOUSE, JR. MANY of the soils in the Southeast require the addition of boron for the most satisfactory production of legumes such as alfalfa and certain clovers. Since root systems of different species show wide variations, especially as to depth of penetration within the soil, it is of interest to determine the movement and accumulation of applied boron within the soil profile. From leaching studies, Krugel (4) reported that boron was easily removed from the soil by successive leachings and that there was no reason to fear that it would accumulate in the soil. Reeve et al. (7) found that 75 to 85% of a 20-pound,per acre application of borax was removed from 7-inch depths of four New Jersey soils when water equivalent to one-fourth the annual rainfall of the region was applied. Borax applied to the surface of a New Zealand soil (1) had penetrated to a depth of 30 inches 24 months after application. Brown et al, (2) found that the available boron in the eighth inch of soil had doubled within 18 months after 20 pounds of borax per acre had been applied to Connecticut soils. More recent work by Kubota et al. (5) in Wisconsin has shown that the movement of boron in soils is primarily related to soil texture. After a period of 6
