Applying gypsum to no-till fields can decrease surface crusting while improving aeration and water infiltration, according to soil scientist Warren Dick at Ohio State University. These benefits can lead to enhanced crop emergence and stronger root development.

Why it matters

Maintaining good soil structure and aeration is crucial for no-till farming, as it allows for better water and nutrient uptake by crop roots. Gypsum applications could be a cost-effective way for no-till farmers to improve these key soil properties.

The details

Gypsum, a naturally occurring mineral, can help break down soil crusts that form on the surface of no-till fields. This improves aeration and allows for better water infiltration, which in turn supports stronger crop emergence and root growth. Ohio State's research has found these benefits from gypsum applications on no-till fields.

  • The research findings were published in April 2026.

What they’re saying

“Gypsum applications on no-till fields could decrease surface crusting while improving aeration and water infiltration, thus aiding crop emergence and stronger roots.”

— Warren Dick, Soil Scientist

What’s next

Farmers interested in trying gypsum on their no-till fields should consult with their local extension office or agricultural advisor to determine the appropriate application rates and timing for their specific soil conditions.

The takeaway

Gypsum shows promise as a cost-effective way for no-till farmers to improve critical soil properties like aeration and water infiltration, leading to better crop emergence and root growth. Further research and on-farm trials will help determine the optimal use of gypsum in no-till systems.
