Farmers grow superfood with environmental, health benefits
Wheatgrass is packed with beneficial nutrients, which makes the crop a popular superfood. And now, more farmers will have access to growing this beneficial crop.
Historically, wheatgrass has been used as a crop in animal feed. However, a partnership between The Land Institute and the University of Minnesota changed that.
This summer, the University of Minnesota released the first food-grade wheatgrass variety for public use. Now, this eco-friendly and cost-effective crop can be commonly grown as human food, too.
The Land Institute has been breeding intermediate wheatgrass since 2002. A variety developed using germplasm provided by The Land Institute in 2011 is the first to be available for public use.
The new variety, called MN-Clearwater, was produced by crossing seven wheatgrass parents with desired qualities. These qualities include high grain yield and seed size, which are ideal for farmers. Breeders have domesticated the perennial crop.
"Because wheatgrass is a perennial, it's known to be a soil builder," said James Anderson, a professor at the University of Minnesota. “It provides soil cover throughout the year.”
Soil coverage prevents soil and nutrient runoff during heavy rainfall. Wheatgrass also has deep, dense roots that capture nutrients before it gets into groundwater. This helps to protect groundwater-based water systems.
Compared to corn and soybeans, growing wheatgrass translates to less soil loss from the field, fewer chemicals and fertilizers entering the groundwater, and improved carbon storage.
There are also economic advantages for the farmer growing wheatgrass. As a perennial crop, wheatgrass uses less fertilizer and machinery than annual crops.
"Wheatgrass can lower the growth of certain weed species," said Anderson. Natural weed control also reduces potential costs for herbicides.
For farmers, the big advantage is that they only must plant once every three years and will have multiple harvests off of the one crop.
"But the farmer isn't the only one who benefits,” Anderson added. “As the first food-grade wheatgrass, food processers and consumers can see a benefit, too."
End-users are always searching for new items. MN-Clearwater wheatgrass provides new flavors and nutritional properties that can be added to food products.
The harvested wheatgrass goes well with wheat-based products. It can be used as a replacement for wheat, but it is best used with it. By using both wheat and wheatgrass as ingredients, the product can maintain its baking and functional properties while offering new flavors.
The first registered food product using the MN-Clearwater wheatgrass was a beer from Patagonia Provisions, and other products include several locally brewed beers and a limited-edition cereal from Cascadian Farm.
