Soil Nitrogen Accumulation Under Black Locust1

Abstract

Abstract

Soil nitrogen accumulation beneath stands of black locust, a leguminous tree, was studied at four locations in Tompkins County, N. Y. Adjacent areas identical in prior treatment served as controls. Significant increases were found under three 16- to 20-year-old plantations but not under a 5- to 10-year stand. These changes extended below the 0- to 7-inch depth, with total nitrogen increases of approximately 600 pounds per acre in the 0- to 20-inch layer.

In a greenhouse study of availability, Sudangrass cultures were able to absorb somewhat larger amounts of nitrogen from soils under locust. Measurement of nitrogen in ground vegetation and estimates of return by locust foliage indicate an annual turnover in excess of 50 pounds per acre.
