Richie3; you can cheat a little by looking at what your neighbours are growing and asking them if they have to add lime to grow alfalfa. Lime is fairly cheap on the scale of things. Also; you can cheat by just mowing the present plot. The alfalfa should thicken up.

You can cheat by buying no name glycophoshate but Roundup does seem to work better because of the additives.

Personally I wouldlook into planting clover in place of the alfalfa but you're pretty far along in your growing season so you need to ask the locals and make sure that you'll have enough rain. Your can cheat on the seed cost by buying generic red or white clover seed from the local Co-Op.

But; you can only cheat so far. If your soil too acid or is lacking in nutrients you can plant the best seed and you'll be disppointed.
