The local bulk clover should be cheap enough that can just broadcast it by hand. For the "No Plow" plot mix Drobs and I got, I bought a hand held spreader at HomeDepot for under $10. I used a fraction of the seed with the spreader that we did by hand. Here's the web page for the plot mix, perennials are expensive because you don't have to buy it every year. http://www.whitetailinstitute.com/products/. My plot is in the middle of almost limitless brouse between the uncut pasture, overgrown fields and hardwoods, but I still get a ton of deer on the plot. Before the plot was there I would get just one or two pictures in two weeks, now I get a hundred.
