Five slowly soluble boron frits were tested with cotton, soybeans, turnips, alfalfa, and crimson clover grown on coarse‐ and fine‐textured soils under greenhouse and field conditions. The frit, FN‐215A, was not sufficiently soluble to provide adequate boron to plants from applications as high as 50 pounds of the material per acre. FN‐176C was more soluble than FN‐215A, but it was not a satisfactory source of boron for alfalfa. Both greenhouse and field tests showed that FN‐176E and 176‐F were the most desirable sources of boron of the frits tested. From tests conducted, FN‐176B was the most soluble source and the one most likely to cause toxicity to sensitive plants. The order of decreasing boron availability was 176B, E, F, C, and 215A. This is also the order of decreasing water solubility as measured by the Rate‐of‐Solution‐Test.
