Farmer's Reminded About Post Harvest Weed Control

With harvest activities starting to wind up in some areas, farmers are looking at their fall weed control.
 
Weeds need to be actively growing in order to get the best result.
 
Crops Extension Specialist Shannon Chant says fall weed control or suppression is helpful in preventing issues in the Spring.
 
"Definitely, things are setting seed before emergence in the Spring. If they set seed before even seeding, then perhaps depending on how Spring is you're kind of eliminating some of that competition," she said.
 
Chant says now up until freeze up is a good time to focus on weed control.

Video: Validating Net Energy in Commercial Swine Systems - Gustavo Lima


In this episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate at Iowa State University, explains how soybean meal net energy is evaluated using growth assays and calorimetry. He discusses caloric efficiency, validation under commercial conditions, and differences between controlled and real-world environments. Gustavo also highlights practical implications for diet formulation and ingredient valuation. Listen now on all major platforms!

“Indirect calorimetry provides a precise estimation of ingredient energy, yet validation under production conditions remains essential for accurate application in real systems.”
