Abstract
Crambe (Crambe abyssinica L.) is a specialty oilseed crop. By‐product crambe meal has a high glucosinolate content, restricting its use for animal feed. The purpose of this study was to evaluate crambe meal for various types of soil application. When incubated with soil, crambe meal mineralized more slowly than soybean meal, with an average of 38% of the added nitrogen (N) from crambe meal appearing as mineral N after 12 weeks of incubation, compared with 57% for soybean (Glycine max L. Merr.) meal. Sulfur mineralization from crambe meal was rapid. Bioassays indicated no phytotoxicity to seedlings from crambe meal. In a second experiment, high rates of crambe meal inhibited the nitrification of urea added to soil, but this effect was short‐lived. In a third experiment, crambe meal–ferrous sulfate mixtures applied to calcareous soil partially alleviated iron deficiency chlorosis of soybean, but the response was less than observed with iron–ethylenediaminedi(o‐hydroxyphenylacetic) acid.
