NNTC 2015 Speaker Presentation

Effects of Cover Crops, No-tillage & Tillage on SOC Sequestration, Storage, Retention & Loss - Kenneth Olson - NNTC 2015 Presentation - MP3 Download


Product Details

Ken Olson will share results of a 12-year cover crops study in southern Illinois on the effects of soil organic carbon (SOC) sequestration, storage and retention, as well as corn and soybean yields. The use of cover crops was studied on these previously eroded soils for its maintenance and restoration of SOC, and different tillage systems were set up with and without cover crops.

The University of Illinois professor will share that while yields were not significantly different under the various tillage systems, levels of sequestered SOC were impacted by cover crop usage. Olson will boil down some action items for no-tillers as a result of the data.
