Anyone grazing sheep on annual summer cover crops? Thinking a mix with say rye, ryegrass, 2 or 3 annual clovers, phacelia, vetch and a brassica with regrowth could be a good mix. Stock it at over 5 ewes and lambs to acre rotational grazed. Could be a good alternative arable 'crop' with benefits of soil conditioning, n fixation. Key being to keep it in a vegetative state.
