No-Till, Strip-Till and Cover Crops Research Journal - March 2026

Each month, the conservation ag group at Cornell University offers an analysis of the latest scientific papers dealing with conservation agriculture research from around the world. For this on-going web series, our editors will be selecting several research papers from the Cornell list that will be of special interest to North American no-tillers, strip-tillers and cover croppers.

In this edition:

  • Sixty years of crop diversification with perennials improves yields more than no-tillage in Ohio grain cropping systems
  • Conservation Tillage Practices on GHG Emissions, Soil Health and Overall Agricultural Sustainability
  • Long-term continuous no-till corn-soybean systems: Examining soil carbon sequestration and nitrogen accumulation across various pools
  • Assessing the agricultural, environmental, and economic effects of crop diversity management: A comprehensive review on crop rotation and cover crop practices
  • Cover Crops Optimize Soil Fertility and Soybean Productivity in the Cerrado of MATOPIBA, Brazil
  • Short-term no-tillage improves soil water retention and maintains soil aeration at high moisture conditions despite reduced macroporosity
  • Tillage Radish as Cover Crop Improves Soil Health Indicators Depending on Pedoclimatic Conditions.
