Digging a soil pit can help no-tillers understand both the limiting factors of their soils, and what makes them tick, as they work to build soil health and higher yields.
A SOIL PIT dug on no-tiller Alan Mindemann’s farm recently shed light on the role no-till practices play in increasing organic matter and making soils more productive. The pit was dug in mid-July on the long-time no-tiller’s farm near Apache, Okla., as more than 50 farmers attended a No-Till on the Plains Whirlwind Expo event.
After the Willfords were told they’d be back to conventional tillage after a couple of years, the Minnesota family is proving no-till and cover crops have a permanent place on their farm
David Brandt may like the nice, green color his fields take on after one of his cover crop mixes emerges. But he also likes to see another kind of green — the color of money.
Increasing organic matter by just 1-2% through eliminating tillage, rotating crops and seeding cover crops will help southern Plains no-tillers keep more water in their soils and increase nutrient uptake, helping make their operations more profitable, says NRCS soil scientist Steve Alspach.
A study found that crop rotations, in isolation from other management factors, can increase the functions performed by soil microbial communities that benefit plant growth.
I’ll have to say, the first time I looked at the U.S. Drought Monitor Index map released for June 2, I was shocked. The pockets of orange, yellow and brown indicating extreme drought in Texas, Oklahoma and Kansas, seemingly permanent fixtures, had all but disappeared in a span of 4-6 weeks.
Check soil pH, phosphorus and potassium levels, organic matter, cation exchange capacity and base saturation on soil test analysis, says AgSource Laboratories.
Iowa State University estimates the economic cost of lost organic matter due to soil erosion and how it affects the long-term productivity of the soil.

On this episode of Conservation Ag Update, brought to you by Martin-Till, Westville, Ind., no-tiller Jeff Herrold provides an update on how planting is going so far, and why a potential problem with slugs is causing some early-season anxiety. Herrold also explains why he prefers to plant soybeans before corn.
