One Nebraska Farmer Says Improving Soil Health Helped Keep Her on the Land

In a moisture deficit area, such as southwest Nebraska, conservation and regenerative practices have long been a staple for farmers. These methods boost soil health and help make their farms more productive and economically stable. That's important especially in drought years such as 2022.
“Conservation is farming in southwest Nebraska." That mindset is a necessity for Tracy Zink. Moisture is typically scarce where she farms near Indianola, Neb., so it’s essential she preserve every drop. She accomplishes that by disturbing the soil as little as possible, even for weed control.
"For the most part all of our dryland we try very hard to be no-till. If weeds get away from us or they’re resistant we try to only do the spot where the resistance is," she says.
No-till practices have improved organic matter and soil health, which keeps even heavy rains from running off and eroding the soil. Plus they leave as much crop residue intact after harvest as possible.
"We try to always have residue on top to help protect soil from blowing," Zink explains. "When I think about soil quality it's also that it stays put."
Crop rotation is also important. On irrigated acres that includes two seasons of corn followed by soybeans. Zink says the dryland rotations are more diverse but depend on moisture levels. We always do wheat, hard red winter wheat is our base for the next crop. Following that, half the acres go to milo and half of our wheat acres go to corn. Then the following year they become corn or milo. The year following is typically summer fallow.
Zink does annual soil testing to set a baseline for fertility, and with the arid environment, she says she has to strike a balance between yield and conservation.
"I don’t look for home runs in yield because I don’t have the water for it. I already have to have that conservation mindset for my yield goals," she says.
Every practice Zink incorporates on her farm must fit into her holistic approach to conservation because she wants to continue the work her grandparents started. "As you look out and around, none of this would be possible if we weren’t incredibly mindful about proper stewardship, soil conservation and managing wind and water erosion."
By improving soil health she knows her farm will be sustainable for years to come.
