Improving soil fertility through conservation practice adoption
Soil health challenges such as erosion, compaction, nutrient depletion and declining organic matter threaten crop productivity and long-term farm profitability in Indiana. Purdue Extension in Indiana, in collaboration with USDA NRCS, Farm Service Agency, Indiana State Department of Agriculture, and local soil and water conservation districts, has played a leading role in addressing these challenges through targeted soil health and fertility education.
The 12th annual Southern Region Soil Health Workshop provided farmers, industry professionals and agency staff with practical, research-based information on conservation practices including no-till and reduced tillage systems, cover crop mixes, soil testing, biologicals and emerging technologies. The half-day program featured Extension educators, specialists, industry experts and experienced producers, ensuring that recommendations were both science-based and practical. A total of 107 participants attended, with nearly half responding to post-event evaluations.
Workshop results demonstrate strong and sustained impact. Eighty-nine percent of respondents reported returning year after year because the workshop consistently delivers relevant, timely information. An equal percentage indicated the program directly influenced their ability to implement conservation practices while remaining financially responsible. Participants reported adopting key soil health practices because of attending the workshop, including no-till or reduced tillage (83%), cover crops to retain nutrients and stabilize soil (82%), regular soil testing (78%), crop rotation (77%) and expanded cover crop species diversity (46%).
By increasing adoption of soil testing, cover crops and reduced tillage, Purdue Extension’s soil health education improves soil fertility, reduces input losses, lowers long-term production costs and enhances farm resilience. These efforts protect Indiana’s soil and water resources while supporting profitable and sustainable crop production statewide.
