I MOST of the work with boron as a plant nutrient, borax (Na2B4O7 . 10H.,O)' has been used as the source of this element, and most of the recommendations made for a specific crop refer to the use of borax. Recently, Rasorite (Na,B4O7 . 4H2O), which is called Fertilizer' Borate °by the fertilizer industry, has become the most commonly used source of boron for fertilizer supplements. In a study of the comparative availability of the boron contained in equivalent amounts of various boron compounds, including borax, Page and Paden found the boron contained in Rasorite to be the most readily available to -corn seedlings grown in greenhouse pot cultures on a Norfolk sandy loam soil, and that contained in Colemanite (Ca2B6O1:L . 5H2O) to be the most slowly available. In view of the narrow range between boron toxicity and deficiency, it seemed advisable to study the effect of this difference in the rate of availability of the boron contained in Colemanite and Rasorite on the yield response of several crops that are known to vary in their sensitivity to this element. A greenhouse pot culture experiment was designed in an attempt to determine the number of pounds per acre of the two compounds that could be added to three selected soil types without producing a significant decrease in the yields of snapbeans, crimson clover, and turnips.
