The Illinois soybean checkoff program, together with IFCA and ILCCA, are hosting free webinars focused on the latest research and management of phosphorus.

Please join us for these important discussions about the best ways to promote strong yields while minimizing negative effects on our state’s precious waterways.

1 CEU in Nutrient Management is available for viewing each webinar. 

Don’t be a Black-Eyed P: How to Reduce P Loss from Fields - Laura Christianson, Ph.D.

Tuesday, March 15, Noon 1 p.m. CDT

As major P-related water impairments continue to generate headlines and stir regulatory interest, there is an increasing need to better understand factors impacting P transported from agricultural areas. Substantial opportunities to reduce Illinois’ point-source P loads exist, but the agricultural sector will nevertheless need to play a role in meeting P reduction targets.

Join Laura Christianson, Ph.D., as she discusses a recent meta-analysis on P transported by drainage water, how P moves from our fields and options to reduce P losses to downstream waters.

Laura Christianson, Ph.D., began her role as assistant professor of water quality in the Department of Crop Sciences at the University of Illinois in September 2015. Her new research and Extension program focuses on environmentally sustainable cropping systems, economically thriving farms, and clean water outcomes. With a background in agricultural engineering, she formerly worked on the design of woodchip bioreactors for removal of nitrates from point and non-point sources, studied options to improve ditch drainage water quality in Maryland, and has done research on drained dairy pastures as a Fulbright Fellow in New Zealand.

Sustainable Thinking 4R Phosphorus - Tom Bruulsema, Ph.D.

Tuesday, March 22, Noon 1 p.m. CDT

Traditional phosphorus management emphasized alleviating deficiencies by building up and maintaining soil-available phosphorus. Society's increasing expectations for sustainability translate to pressure to improve efficiency and reduce environmental impact. Improving phosphorus use efficiency involves making better use of the P in manures and other wastes. Reducing environmental impact means reducing the losses of all forms of P.

Join Tom Bruulsema, Ph.D., as he describes how a practical consideration of all 4Rsright source, right rate, right time, and right placecan make big contributions toward achieving both goals. 

Tom Bruulsema, Ph.D., is Phosphorus Program Director for the International Plant Nutrition Institute. Based in Guelph, Ontario, Canada, he has led research and education programs for the Institute in Eastern Canada and the Northeastern U.S. since 1995. Dr. Bruulsema has been recognized as a Fellow of the American Society of Agronomy, the Soil Science Society of America, and the Canadian Society of Agronomy. He has played key roles in the development of the 4R Nutrient Stewardship concept, including the co-editing of the IPNI 4R Plant Nutrition Manual.

Fertilizer Management Practices to Reduce the Loss of Dissolved and Sediment-Bound - Antonio Mallarino, Ph.D.

Tuesday, March 29, Noon – 1 p.m. CDT

Join Antonio Mallarino, Ph.D., as he highlights field research results which show that several phosphorus fertilizer and manure management practices can optimize corn and soybean yield, are cost-effective, and minimize the risk of dissolved and soil-bound phosphorus loss with surface runoff. 

Antonio Mallarino, Ph.D., is a professor of agronomy and nutrient management research and an Extension specialist at Iowa State University. His programs focus on agronomic and environmental issues of nutrient management with emphasis on phosphorus, potassium, lime and micronutrients. Issues addressed include soil and plant-tissue sampling and testing, fertilizer and manure placement methods to increase nutrient use efficiency and crop yield, use of variable-rate technology, and phosphorus management impacts on water quality.

Webinar recording available here.

All webinars will be moderated by Pete Fandel, associate professor of agriculture at Illinois Central College and cover crop specialist with Illinois Council on Best Management Practices (CBMP).
