NutrientSmart 2018 Program

The what, where, when and how to apply crop nutrients

Friday, January 19, 2018

Waterloo, ON

Registration:  Registration open on-line or call the AICC 1-877-424-1300.

A Systems Approach to Fertility Management for Crop Production

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.

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

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

John Lauzon, U of Guelph/Chris Brown, OMAFRA

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

• 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?

11:00 am Nutrition Break

11:15 am – Phosphorus Losses from Agricultural Soils and Loading To the Great Lakes: Implications for Crop Management

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

12:00 pm – 4R Nutrient Stewardship Approaches in Ontario

Dale Cowan, Agris Coop

• What is 4R Nutrient stewardship
• Where did it come from
• How is it impacting Great Lakes Farmers
• When is it coming to Ontario
• What are the implications of 4R for my farm?

12:30 pm – Lunch

1:15 pm – Cropping System Nutrient Mgmt: A Crop Advisor and Extension Specialist View

Jake Munroe, OMAFRA & Chris Snipp, Agris Coop

• Practical steps to better fertility mgmt for a cropping system and the financial and environmental benefits that are its result
• Essentially the 4Rs, when in the rotation, where in the landscape, how in the landscape, how much, what mixture of sources (organic and inorganic, and accounting for soil pool supply
• How to hold it for the crop
• Targeting to prevent luxury feeding and/or residual following crop maturity
• Tools and record keeping
• Doing, interpreting and using soil testing and reporting
• Philosophies of nutrient management, sufficiency vs build and maintain methods
• NUE in terms of timing, placement, etc
• Scenario based where possible

2:15 pm – Nutrition Break

2:30 pm – Cropping System Nutrient Mgmt: A Farmers View

Marc Hasenick, Springport MI
Warren Schneckenburger, Morrisburg 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

Participants will be thanked for their participation at 4.00pm, and the Panel discussion will be introduced indicating to the crowd that they are free to leave immediately or as necessary during the discussion as long as they do so quietly.

4:00 pm – Speaker Panel

All Speakers
• Open Q&A among the days speakers to address burning questions of the audience.
