Agronomic Conservations to Address Supply Chain Disruptions

Given current global challenges, lawmakers have proposed allowing select land currently enrolled or soon-to-be enrolled in the Conservation Reserve Program (CRP) to be opened for crop production in the immediate future. In 2021, approximately 315,000 U.S. producers received CRP payments, accounting for roughly 22 million acres enrolled in the CRP program or 8.7% of U.S. cropland.

ASA, CSSA, and SSSA members and certified professionals drafted scientific and agronomic considerations that address a potential shift in land use out of conservation and into crop production. We recognize that these are not the only points to be considered and acknowledge the growing global food security challenges brought on by Russia’s invasion in Ukraine.

The following are the key takeaways from the report:

  • In most cases, converting CRP acres to crop production is resource intensive and may require more time and agronomic inputs than currently available prior to the 2022 growing season. Conversion may be more feasible for the 2022 winter growing season or 2023 spring growing season.
  • Crop yields tend to be below average the first year after CRP is converted to cropland. Combined with high input prices and low supply, producers may face economic challenges upon converting CRP to cropland at this time even though crop prices are also high.

Intrauterine Vaccines in Swine - Dr. Heather Wilson

Video: Intrauterine Vaccines in Swine - Dr. Heather Wilson



In this episode of The Swine it Podcast Show Canada, Dr. Heather Wilson from VIDO at the University of Saskatchewan explains how intrauterine vaccination is being developed as a new option for swine health. She shares how formulation, adjuvants, and delivery methods influence immune responses and what early trials reveal about safety and reproductive performance. Listen now on all major platforms.

"The idea was that an intrauterine vaccine might avoid a tolerance response and instead create an active immune response."

Meet the guest: Dr. Heather Wilson / heather-wilson-a8043641 is a Senior Scientist and Program Manager at the Vaccine and Infectious Disease Organization at the University of Saskatchewan. Her work centers on vaccine formulation and delivery in pigs, including the development of intrauterine vaccination to support reproductive health and passive protection of piglets. Her background spans biochemistry, immunology, and functional pathogenomics.
