Abstract/Contents:"The use of canola meal as an organic source of nitrogen for turf was evaluated along with six other organics. In addition, two trials were conducted on the possible effects of incorporating this product into a rooting medium and examining seedling development. Canola meal again proved to be the top rated organic fertilizer as it rated highest in total clipping production, and was equal to Turfmaster in turf density. In turfgrass colour Turfmaster, Turfmaster Plus and canola meal were the top ranked organics. The canola meal gave a consistent level of clipping production as it was the only organic that produced significantly more clippings from week three to week seven than the control plots. This would indicate that there is a uniform release of nitrogen over time. Refer to the nitrogen source fertility trial tables and graphs illustrating these results. The use of canola meal as a soil ammendment when establishing sensitive crops, such as water cress or creeping bentgrass seed, proved to inhibit normal establishment of seedlings. In previous agricultural studies it was found that there were detrimental effects of volunteer Brassica (canola) on production of certain cereal grains (McGregor 1987). He cited the possibility of detrimental effects from phenolic acids, or glucosinilates contained in Brassica seed, incorporated field stubble, and chaff. A laboratory analysis conducted by Nor-West Labs of Edmonton indicated very low levels of metals in the canola meal when compared with other available organic fertilizers."
