1a.Objectives (from AD-416):
To provide outreach programs to farmers and consumers in Iowa and Illinois on the holistic agronomic management systems that include no-tillage, multifunctional cover crops and gypsum soil amendment to enhance soybean productivity while improve soil quality and mitigate climate change.
1b.Approach (from AD-416):
Establish demonstration plots at the Farm Progress shows to demonstrate the efficacy of (1) no-till versus conventional tillage, (2) gypsum (2000 lbs/acre) versus no-gypsum soil amendment, and (3) cover crop versus no cover crop on soybean seed yield.
Demonstration plots were established at the Iowa Farm Progress Show site near Boone, IA. The site was staffed each day during the show to greet and inform visitors to the plots about the innovative farming system being promoted to increase soybean yield and improve soil health on marginal soils. The plots were managed during the 2013 cropping season in order to maintain the treatments for the 2014 Iowa Farm Progress Show. No suitable field site was available for establishing demonstration plots during the 2013 Illinois Farm Progress Show. Literature about the farming system and the project objectives was made available to Illinois Farm Progress Show visitors in conjunction with the Illinois Soybean Producers in their display booth.
Activities conducted for this project contribute directly to Sub-Objective 2a of the parent project: Evaluate no-till, soil amendment, and cover crop practices as compared to conventional management practices for improving crop yield and soil/water quality in intermittently wet soils.
