Judd Hill Project: Integrating Soil and Water Conservation and Pest Management Strategies for Sustainable Cotton Production
A joint effort by Arkansas State University, USDA-ARS, University of Arkansas, and Judd Hill Foundation to quantify the benefits of conservation practices to improve the sustainability of cotton production, including pest management, water-use efficiency, and water quality. This project is a research-based project at the Judd Hill Foundation farm, which is representative of 1000s of acres in the northern Mississippi Delta region. Conservation tillage, cover crops, and grassed filter strips in conjunction with IPM for these different systems has been implemented and meticulous data collected on crop growth and development, yield, and various environmental aspects including nutrient run-off and GHG emissions.

Engagement Targets
Notes: (1) Minor fluctuations in the number of retained growers is expected from year to year. These fluctuations may be due to year-over-year crop rotation effects or other factors beyond the control of the project. Enrolled acres represent the total number of acres on an individual farm in a specific year. The ability to report enrolled acres is based on the Fieldprint Project Standard requirement that individual growers enrolled in projects enter at least 10% of the acres managed for a specific crop. (2) Entered acres represent the actual number of enrolled acres for which data is entered in the Fieldprint Platform for analysis.
Objectives
Promote adoption of conservation tillage systems with demonstrations of cover crop technology showing the profitability of reduced tillage systems.
Promote adoption of conservation tillage systems with demonstrations of cover crop technology showing the profitability of reduced tillage systems.
For both irrigated fields, the conservation management system had similar yield compared to the conventional management system (1561 and 1570 lb/acre, respectively). This demonstrates that incorporating cover crops and reduced tillage does not significantly decrease yield in cotton.
Demonstrate soil moisture monitoring via irrigation scheduling during field days and workshops.

In June 2024, the Judd Hill Foundation held an educational field day for middle school students to learn about irrigation practices and cotton production.
Document significant improvements in runoff water quality associated with conservation systems in a replicated large scale field trial with edge-of-field monitoring.

By utilizing conservation practices (cover crops and reduced tillage) in cotton production, we were able to mitigate two additional pathways for nutrient loss into water as compared to conventional methods. These practices also reduced soil erosion about 38% -- from 3.9 to 2.4 ton/acre/year.
Quantify greenhouse gas emissions to determine any effects of conservation practices.

No significant difference was found in greenhouse gas emissions among the different treatments.
