Kudzu is one of the most amazing plants on the planet. You can use it as a green manure, use it for forage, rabbits, goats, chickens etc all love it. The plant is loaded with bioflavenoids and is highly medicinal. I use it in my Champion juicer in place of wheat grass. It is amazing when you drink it with some orange juice.
I am going to use it to make rope and to feed my animals. Additionally it will fertilize my soil and keep my soil from eroding as bad. You can plant rows of corn or other plants between rows of kudzu. The kudzu fixes nitrogen like soybeans and also will drop leaf litter that composts down very good. If you take a sample of soil from an old patch it will be black dirt and grow food for free. Not having to pay for fertilizer is my key to bring more inputs to my homestead.
I currently have a 55 gallon drum outside filled with kudzu that I weighted down with some bricks and covered in water to ret it. I am going to extract the fibers, the inner core is translucent and very strong. Channing Cope talked about using rotational farming with kudzu, alfalfa, kentucky fescue 31 and lespedezia. They had a rotation schedule. The only reason I would say they did not just do all kudzu is because it grows until frost and dies so about 1/2 of the year. You can bale it, needs to be cut low with a sickle mower and baled high. I am still experimenting with mine.
Also to get the seeds to sprout in Japan they use 6-7 needles in a bunch and scarify the seeds repeatedly. I would not recommend seeds if you want it a crown works very good and layering vines as they mature will ensure more root growth and vigorous growth.
