We harvest about 200 acres of just hay a year. Your best bet for planting for just food plots is to disk the site throughly, use a broadcast seeder and then go over it with a roller. Don't plant till you know it is going to rain that day or the next. If it doesn't rain the seed won't get the extra help it needs to start growing. Also your best bet is to plant in the fall not the spring, because in the spring the weeds are to heavy and will take the moisture away from your alfalfa seed not to mention the weeds will take over the field. If you do plant in the fall, the following summer the alfalfa will be growing great and it will be florishing by fall. Don't forget that you will need to mow it, wait till it blooms and then mow down. It will pop back up and it grow in fuller
