Studies of boron deficiency in Idaho soils
1939
Colwell, W.E. | Baker, G.O.
1. A greenhouse method suitable to detect boron-deficient soils is described. A good correlation was obtained between greenhouse and field experiments. 2. Preliminary field tests in northern Idaho indicate that fall applications of borax at the rate of 40 to 60 pounds per acre are superior to spring applications in overcoming yellowing in alfalfa. 4. The results of a limited number of analyses on alfalfa indicate that a high boron content of alfalfa is associated with freedom from yellowing. 4. The investigations are of preliminary character. Further work is being done to substantiate these findings.
