Deer love it...i sell it and have used it on the large farms for fall cover crops after wheat is taken off. It fixates 100 units of nitrogen in 6-8 weeks and can get tall. It needs heat and will die fast once it freezes. After a frost it decomposes fast, so that you don't hardly know you had it planted. The other advantage is that once the deer kow it low to the ground, it will regrow faster than most forages. I have an experimental mi going in across the US called fast gro and the deer loveeeeeeeeeee it.
