What I've Learned from No-Tilling

Intercropping, Cover Crops Yield More Residue, Fewer Inputs & More Income

On the dry, wind-swept Colorado plains, more residue above and roots below are critical to John Heermann’s no-till system.

SOIL HEALTH DRIVES nearly every farm management decision I make these days. It’s why I use a stripper header, diversify my rotation, use cover crops and am ramping up intercropping. It even determines what gifts I send to my landlords on the holidays (books on soil health)

Reducing Fertilizer, Boosting Yields with Sap Analysis

Crop consultant John Kempf explains why plant sap analysis can provide the best agronomic information no-tillers will ever collect and how to make use of the results on your farm.

What if you could decrease your nitrogen (N) and potassium (K) applications — anywhere from 30-70% — while increasing yields and crop health? That’s what John Kempf found from managing nutrition properly on many of the farms he works with, thanks to plant sap analysis.

What Research & Literature Most Contributed to No-Till’s Adoption?

This first-ever project recognizes the most significant works in no-till research & literature, and the efforts of those who contributed to the practice’s understanding in North America and beyond.

In September 2021, No-Till Farmer commissioned a project to determine the most significant research and publications that assisted in the understanding and adoption of no-till agriculture. Randall Reeder, retired ag engineer from Ohio State Univ., and Don Reicosky, retired USDA soil scientist, collaborated on a detailed process to complete this large and aggressive project in advance of three important no-till milestones in 2022.

The No-Till History series is made possible by Calmer Corn Heads.

Study: Intensive Nitrogen Stymies Organic Carbon Accumulation

University of Illinois’s natural resources and environmental sciences professor Richard Mulvaney wanted to know why soil organic carbon matter is disappearing from agriculture fields despite years of intensive residue inputs. So he set out to determine whether nitrogen fertilization might change the composition of corn residue, and whether that impacted carbon sequestration as a result.
