A Systems Approach to Fertility Management for Crop Production
Has to fit into 4R nutrient stewardship
The how, when, where and what to apply in crop nutrients
The context is building a holistic nutrient management plan for a grains-based cropping system. When, how much, source (what), where to apply nutrients in the cropping cycle to get best nutrient use efficiency and least environmental loss. What’s good economically from a profitability standpoint should be good from an environmental standpoint. While building around a grain cropping system the principles and actions should apply in any cropping system although more complex rotations, and more horticulture focused cropping complicate the planning process as does the inclusion of organic amendments.
CEU Credits – 3.5 Nutrient and 3.0 Soil and Water
9:00 am – Soils and Soil Fertility 101
Ray Weil, University of Maryland
The Interaction Between Soils, Crops, and Nutrients
• Big picture discussion on how fertility interacts with soils and how changes/variability in soils influence how plants interact with nutrients
• Basic soil science principles
• Net inputs and outputs and flows within the system. The “big picture” of how nutrients enter and exit agricultural systems.
• Interactions of soil physics, chemistry and biology
• How to “tighten up” nutrient cycling in ag soils and improve crop nutrient use efficiency
Ray Weil is a professor of soil science at the University of Maryland where he teaches five undergraduate and graduate courses. He has taught over 6,000 undergraduate and graduate students in his university courses, addressed over 5,000 farmers at meetings and field days, and helped train hundreds of researchers and managers in numerous companies and organizations, including the World Bank. He has been the major advisor for 40 MS and PhD students in the US and has co-advised numerous others at African universities. He is a Fellow of both the Soil Science Society of America and the American Society of Agronomy and has twice been awarded Fulbright Fellowships to support his work in Africa. He is probably best known for his ecological approach to soil science as coauthor of the 11th – 15th editions of the most widely adopted and cited textbook in the field, The Nature and Properties of Soils, by Brady and Weil. He is a leader in researching and promoting the adoption of more sustainable agricultural systems in both industrial and developing countries. His research focuses on soil organic matter management for enhanced soil ecosystem functions and nutrient cycling for water quality and agricultural sustainability. Weil’s research program combines three interrelated areas: 1) Organic matter management for soil quality; 2) Sustainable cropping systems; and 3) Soil management for improved nutrient cycling and water quality. His research probes fundamental relationships between soil organic matter management and soil ecological functions. His soil quality program has achieved international recognition for its innovative efforts to develop a soil quality index and methods for the rapid, routine assessment of soil quality indicators. The analytical methods for soil microbial biomass and labile soil C that he developed have been adopted by the USDA/NRCS and are used in ecosystem studies worldwide. His contributions to improved cropping systems, including innovative cover crops, are now increasing on-farm biodiversity and improving soil function on farms large and small. He is an expert at diagnosing soil-related problems in the field. He has worked with the Ag Center to develop the SoilDoc, an package of innovative methods for on-the-spot soil analysis to assist in field diagnosis.
9:45 am – Nutrient Sources and Their Equivalency or: Getting Value out of Organic and Inorganic Nutrient Sources or: Integrating Organic and Inorganic Nutrients Sources on the Farm
Chris Brown, OMAFRA & Bill Deen, University of Guelph
Effective use of Organic and Inorganic Nutrient Sources
• Discussion about inorganic and organic sources of the same nutrients in terms of similarities and differences.
• N is N from either source as is P etc although from organic will continue to become available as mineralization continues
• Manures bring biology which can be very beneficial
• Manures are heavy and nutrient concentration can be variable and requires caution around application for uniformity, compaction and rate, requires testing for full advantage
• Managing organic nutrients sources for maximum nutrient benefits – timing, placement, source and rate
• New estimates of N availability from fall/spring applied manures
• Ways to access organic nutrients for cash crop systems
10:15 am – Understanding the Sources, Causes and Implications of Nutrient Losses to Water
Christopher Winslow, Director, Stone Laboratory, Ohio Sea Grant College Program, OSU, Put-In-Bay, OH
• Why and how do nutrients leave the farm landscape and why is this problematic
• What are the sources of nutrient losses
• What are the consequences of nutrients leaving the farm
• Why is Lake Erie such a “Canary in the Coal Mine” with respect to water quality
• The problem explained in laymans terms
• What can we do to address the problem?
Dr. Chris Winslow received his B.S. from Ohio University and both his M.S. and Ph.D. from Bowling Green State University. Since 2004 Chris has been a fixture at Ohio State University’s Stone Laboratory, first as an instructor and research supervisor, but now as the Director of both the Lab and the Ohio Sea Grant College Program. Prior to joining OSU and Ohio Sea Grant, Chris was an Instructor at BGSU (2002-09) and an Assistant Professor at Kutztown University of Pennsylvania (2009-11).
11:00 am Nutrition Break
11:15 am – Phosphorus Losses from Agricultural Soils and Loading To the Great Lakes: Implications for Crop Management
Mark Williams, United States Department of Agriculture, Agricultural Research Service
Understanding P Movement and Interaction with Soil
• Given that P has been proven to be leaving farms and that the environment and other factors around Lake Erie have changed, what are the implications for building nutrient management programs for efficient and effective crop production
Mark graduated in 2008 with a B.S. Environmental Resource Management at Penn State University. In 2010, he graduated with a M.S. Agricultural and Biological Engineering at Penn State University. In 2013 he received his Ph.D. Agricultural and Biological Engineering, Penn State Univ. Between 2013-2016, Mark worked on his Post Doc, USDA-ARS Soil Drainage Research Unit, Columbus, OH. From 2016 to today Mark is an Agricultural Engineer with the USDA-ARS National Soil Erosion Research Lab, West Lafayette, IN. His research focus includes Subsurface hydrologic and biogeochemical processes affecting nutrient transport; preferential flow and phosphorus dynamics; subsurface tile drainage; tracing water and nutrient flow paths through the landscape using stable water isotopes; effect of agricultural conservation practices on water quality at both field and watershed scales.

2:15 pm – Nutrition Break
2:30 pm – Cropping System Nutrient Mgmt: A Farmers View
Marc Hasenick, Springport MI
Warren Schneckenburger, Morrisburg ON
Gord Green, Embro, ON
• The speakers each operate successful farms and will share their approach to nutrient management given their unique circumstances of their geography, soils, farm systems etc
Marc returned to the family farm after graduating with a bachelors in Crop & Soil Science from Michigan State University in 201. A paradigm shift after the 2012 drought initiated a whole farm transition in an attempt to “weather proof” their acreage. Like the prior generations, early adoption of unconventional practices proved successful and the farm grew into a 100% no-till, cover cropping, precision Ag embracing, data creating machine. Constantly trying to exhaust the resources of data collection and analysis with soil health as goal #1 are the cornerstone of the operation today.
Warren Schneckenburger operates Cedar Lodge Farms in Morrisburg with his parents, Arden and Rhonda, and his wife, Christine. Warren is a graduate of the Ag Economics Program at MacDonald College, McGill Univeristy. They produce corn, soybeans, wheat and edible beans along the St. Lawrence River, and also have a beef feedlot. Warren is also a director with OSCIA and member of IFAO.
