If you need to get roots fast, you need to mix in an annual rye. It will root and grow very fast and allow the rest of the mixture time to root. You may also want to mix in a little rye to avoid wash out if you let them in your pasture when you shouldn't have. It will bounce back quickly. I don't think this dude is saying to plant the whole damn field in rye.

Very happy. Lol

Better than almost any other crop

Cultivation or mow it in late flowering for silage. From the video this particular crop will be combined so will die naturally as it’s an annual and the volunteers could then be controlled though silage making or cultivation

Same challenges: species/cultivar selection and mix for your soil and climate, timing into rotations, establishment, incorporation/ knocking back, sowing 'cash' crop through residue in time, getting the cash crop out and a winter green manure established in time. Difference is scale. I've no machinery for my garden sop I only sow what I can slice down with hand shears then incorporate by lightly slicing into the soil with a spade. Rye was the hardest to incorporate with spade, particularly with a heavy silt soil that compacts so I won't be using that again. Clovers (fixer), field beans v. faba (fixer), sunflower (lifter), chicory (lifter) were easier. Daikon radish (white icicle) I tried as a 'cash' crop because but it didn't go deep However the inputs to one's normal rotation for a gardener / allotmenteer isn't costing tens of thousands of £/$, machinery / fuel isn't costing hundreds of thousands and one's livelihood doesn't depend on results.
