Bridgewater Dairy, a family farm in Montpelier, Ohio, has 3,000 dairy cows that produce 30,000 gallons of milk daily. They also produce an estimated 15 million gallons of manure each year.

A decade ago, Chris Weaver, Bridgewater Dairy’s chief operating officer, started turning his farm’s animal waste into something valuable — electricity — by installing an anaerobic digester.

“I wanted to manage the animals’ manure with an eye to helping the environment,” Weaver says. “I also wanted to improve the comfort of my cows. An anaerobic digester lets me do both.”

If you’re going to take a shot at growing your own dinner this year, a good place to start is by picking the crops that offer the best return on your investment.

Experienced gardeners quickly learn that some types of home-grown vegetables work out better than others.

Choices such as onions and peppers, for example, perform reliably well with few setbacks throughout most of the country, while crops such as broccoli and spinach often run into bug threats and have fairly narrow planting-time windows.
