Improving agricultural management practices to improve soil health, reduce nutrient runoff into area waterways, conserve water, and increase crop yields and quality. We collaborate with industry, research centers, agencies and environmental organizations to advance multidisciplinary and whole system management practices for the agricultural lands that impact our nation’s waters.
Healthy Soils for Healthy Waters
Soil and water research and policy leaders, headed by The Ohio State University with support from Greenleaf Advisors, LLC, and the University of Arkansas launched a workshop and symposium series dedicated to the development of multidisciplinary and whole system management practices for the agricultural lands that impact our nation’s waters. A collaborative multi-year effort, the series has been organized around the development of data-driven, case studies highlighting conservation practices to reduce nutrient exports to water resources, improve soil quality, and increase yields. In 2020, we are organizing a sensor technology workshop with the Illinois Sustainable Technology Center at the University of Illinois to benefit agricultural soil health for water use efficiency, carbon sequestration and plant nutrient availability.
Gypsum as a Best Management Practice
Nutrient runoff from agricultural fields impacts the integrity of aquatic ecosystems, and the quality of water resources across the country.
Research results in the Maumee Basin of Ohio (led by The Ohio State University) and the Walnut Creek watershed in Indiana (led by Indiana University-Purdue University Indianapolis) demonstrate how gypsum helps sediment and nutrients stay on the land and out of the water.
Perennial Biomass to Reduce Nitrates
Agricultural production in the Midwest has been associated with nutrient resource losses through water, causing eutrophication in Great Lakes and Mississippi River watersheds, local impairment of drinking water sources, and Gulf Hypoxia.
Greenleaf provided communications, development, and outreach for Argonne National Laboratory on its agricultural research in Illinois where they study the growth of native grasses in otherwise unproductive farmland to produce bioenergy crops, thereby reducing nutrient pollutant flows into streams and sequestering greenhouse gases in soils.
