S 28 ^9 YEAR Fig. T. Shoiving average pH value of tivo groups of plots, 1925-31, one of ivhich received two tons of ground limestone per acre and the other four tons Excellent crops of alfalfa have been obtained from soils having a pH value as low as resulting from the application of two tons of ground limestone per acre. The use of an additional two tons of limestone increased the pH of the soils markedly but did not result in a significant increase in yield. II TOP-DRESSING HAY A portion of the same field on the Whenal farm where the alfalfa experiment was conducted was plowed in August 1925 and prepared for a fall seeding of timothy. Prior to seeding certain plots were ma- nured and lime applied as a cross treatment at the rate of two and four tons per acre, with an equal number of plots unlimed. Twelve plots, representing the old sod, were left unplowed, one at either end of each of the six tiers of plots. Beginning in 1926 six of.
