well like every thing, you can do a cheap way or the right way
and many times the results are based on how you invest
that said, it can make a difference doing even just a cheap try
meaning you can just frost seed the roads with clover seeds in the spring time, and sure some clover will grow
but by hunting season, most will be over taken by weeds
you can just spray with round up in spring and keep it dead till a summer planting, and then again just scuff up the ground with an old piece of chain link fence and fertilize and lime and seed, and again clover, and many other things will gorw,
you just will not get great takes
BUt deer will still find it and feed on it, as it will be an improvemnt to the area for them
nothing is cheap these days,
but if you look at it as an investment, its easier to swallow
any thng you plant will improve your hunting lands, even cheap ass plots
but like I said, once you start to see what they can do, you tend to get more involved and go bigger, like most hobbies
the possitive like I said, is almost anything you buy, you should be able to sell pretty easy, and hunters every yr do food plots more and more!
good luck
