Where do you live? That might make some difference.

Join your local farmers and ranchers co-op. They will have the best prices for everything. For example, if for some reason you decide to spray molasses on your fields, molasses costs $15 per gallon anywhere. At the co-op it will be more like $1.10 per gallon if you bring in your own containers. If you were to apply organics, typically we buy in 50-pound bags. You would be buying in feed lot quantities, unbagged. We're talking 7,000 pounds at a time to apply at 15 pounds per 1,000 square feet. That would be 3.5 tons of stuff. I'm thinking around 5 cubic yards. Of course you'll need real farm equipment to apply anything or to mow.

What did the former owners do? Are there nearby farmers who might want to raise crops on the land? If you do nothing but let stuff grow however it will, you will at least need to cut it down periodically to keep it from growing up wild. If you put up a fence maybe you could keep a few goats to keep it from growing up too much.

For the below, I'm assuming you're in the northern tier of the nation. Southern answers will vary, so let us know your general location.

If you want lawn in that huge area...oh, heavens, am I going to hear about this one...

For most of it? I think I'd go with cheap, low-maintenance, high durability grass like K31. If you mow it and overseed a bit every few years, it'll look fine. Nothing spectacular, but fine, and it'll tolerate neglect that most other grasses won't. The seed is also incredibly cheap.

On 11 acres, copses of trees would also be a possibility, provide some wind breaks, and areas for animals to live. If you like having animals about (I do), that is.

Then I'd maintain a designated area around the house, perhaps 10,000 to 20,000 square feet, that you really care for. That would be the area of lawn that you use, look at a lot, play on, and enjoy most of the time. That reduces the amount you need to expend much effort on considerably and reduces the price of most maintenance to 1/15th what it would be on the whole property.
