A relatively large accumulation of nitrate is common in tobacco land in Kentucky in the fall after the crop has been removed. This is due to the selection of productive land for the crop, the excellent tillage and frequently liberal fertilization given, and the nitrate corning from the roots, sucker growth, and other remains of the crop. In the absence of a proper cover crop, a large loss of nitrate from such land in the drainage water during the winter is probable. In previous nitrate work by the writer, it was observed that apparently wheat seeded at or after the usual time (around October 15, the Hessian fly-free date at Lexington) frequently does not make sufficient growth to be very effective in taking up the nitrate in
