planting alfalfa is not a waste of time you should get a soil anaysis done first to see how much of lime and fertilizer you will be needing. you should try to use a mixture, alfalfa has a tap root system so it will not hold the soil together well without some help. tyr using some type of grass into your plot with a fiberous roots system will save your soil and also help in your stand. i live on a farm and we farm around 2500 acres and alfalfa is a deer magnet. but you will have to just take your time and not hurry through the process. good luck.
