Combating the effects of climate change, from severe floods to drought, a Nebraska farmer is combining new regenerative practices with lessons from the past to become more sustainable.As Graham Christensen and his brother harvest their fields in Oakland, there is already another crop waiting to take its place."See this? This would be rye grass. So it's just starting to peak up," Christensen said. About a month ago, Christensen used drones to drop seed in his corn and bean fields."As soon as they come out and that sun hits the ground, more and more you see that cover crop flourish," Christensen said. It's all part of regenerative farming practices, including not tilling fields after harvest and using cover crops."We've definitely noticed a minimization of moving soil rolling down the these steep hills in this area that we farm," Christensen said. It helps during floods and drought."We're seeing that it's holding the moisture in some of these areas as we slide aggressively into a drought," Christensen said. Christensen became concerned about the environmental impact on agriculture about 15 years ago, and how to keep his fifth-generation farm sustainable."We have a long-term approach. So the investment we're putting in to add this extra biodiversity, soil armor, permanent roots, is paying off," Christensen said. Certain cover crops help soil health and reduce chemical use."We cut down 40 pounds per acre since we started this program five years ago, of the nitrates that we're actually applying," Christensen said. He's studied how indigenous people fit into the environment and planted native grasses for buffers to waterways."And minimized the amount of contaminants that are working its way to our waterways," Christensen said.He also uses livestock to graze."As an animal starts to move around here more then I can further reduce that synthetic nitrogen reduction further and further down," Christensen said. Christensen was able to tap into grants from the Conservation Stewardship Program of the Farm Bill. He hopes that can be renewed by Congress."That program was the No. 1 program that de-risk our ability to learn how to be able to do this," Christensen said. It's opened up food-grade markets because of their practices. "We've started to notice that we've actually per acre increased our net profit a little bit. So we're heading in the right direction," Christensen said. And that's the bottom line.
