Canola is known as a non-mycorrhizal-associated plant and for its biofumigation of soil. This may lead most to think that it is not very friendly to biology; however, it still has many biological associations.
Pre-sowing Lime and Gypsum are often critical inputs that increase crop success. This, in conjunction with good base Phosphorus inputs and compost, ensures the crop has what it needs to develop a well-developed root system with early vigour.
Application of Nitrogen sources at sowing has been reduced or not applied at all to avoid root burn during the early stages of crop growth. With most growers just opting for MAP and Worm Granule to start the crop. Applying nitrogen post-sowing has become commonplace.
Seed dressing still offers benefits for canola seed, helping it germinate well. A good seed dressing focuses on key elements, such as phosphorus and zinc, while including a range of good feed sources to support biological nutrient solubilisation.
In crop, Nutrition is definitely broken up into two parts, vegetative phase is critical to build biomass during the cabbage stages, this typically focuses on N, P, Mg, S, Fe and Zn while during the bolting stages which are the plants reproductive stages these is a greater focus on Ca, Mn, Cu, B, Mo and Co these contribute to protein synthesis which is the conversion of nitrates into Ammino acids and Proteins. It is during this phase that has a pronounced effect on increasing grain yields with canola.
