On limed Waynesboro very fine sandy loam at the Heavener Soil and Pasture Station in southeast Oklahoma, alfalfa gave highly significant increases in hay yield with additions of 32, 64 and 96 lbs. P 2 O 5 per acre applied as 0‐20‐0. These phosphorus treatments combined with 72 lbs. K 2 O as 0‐0‐60 gave larger increases over the respective P 2 O 5 treatments alone. The addition of 40 lbs. borax to the 0‐64‐72 treatment resulted in the highest yields in the experiment, averaging slightly less than 4 tons per acre annually for the 3‐year period 1951, 1952, and 1953. This was more than double the check plot yields. Yields were lowered 569 lbs. hay per acre with addition of 480 lbs. MgSO 4 to the P 2 KB treatment. Five tons of manure gave lower yields than the low phosphate treatment; the manure reinforced with 64 lbs. P 2 O 5 yielded slightly less than the 96 lbs. P 2 O 5 treatment. The range in total boron content of alfalfa was 15 to 70 ppm. Water soluble soil boron from the experimental plots ranged from 0.02 ppm. for untreated borax plots to 0.31 ppm. for plots receiving borax. Total boron in alfalfa was related to water soluble boron extracted from corresponding soil samples giving a correlation coefficient of 0.551.
