Culling, the selective removal of specific individuals within a herd, is a common management practice within the dairy industry and can be important for maintaining healthy herds. This study, led by researchers from Texas A&M University and Colorado State University, analyzed data from U.S. organic dairy farms to better understand how, when, and why cows are culled.

In this free online course prepared by the Organic Agronomy Training Service (OATS), learn about managing soil health and fertility in organic field crops commonly grown in the northern tier of the U.S. The course will cover: soil health fundamentals; organic fertility management strategies; allowed fertility inputs; crop rotation strategies; and more.

Living mulches offer potential for weed management in low or no till systems. In this episode of the Field, Lab, Earth Podcast, University of Wisconsin's Ben Brockmueller discusses cover crop management in corn as a means of weed suppression.

Biofertilizers are soil biological supplements containing microorganisms in organic media that can improve nutrient availability and reduce the need for traditional fertilizers. This factsheet gives a high level overview of biofertilizers in desert cropping systems, including cotton.

Learn successful IPM strategies for the organic management of gophers, moles, and voles from UCCE staff and experienced growers in this informative webinar.

This final research report from OFRF and Kay Bell of Passion Garden highlights farmer-led research conducted to investigate the effect of mesquite bean meal as a soil amendment on tomatoes.

A participatory on-farm research project was conducted on five certified organic coffee farms in the Kona district on the Island of Hawaii to evaluate alternative organic-based practices for the management of Coffee Leaf Rust (CLR). Coffee…

Balancing nitrogen and phosphorous rates can pose an ongoing challenge for organic growers. The high level of phosphorous (P) relative to nitrogen (N) in many organic fertilizers frequently results in an overapplication of phosphorus, which can be harmful to the environment. Researchers in California performed a series of experiments evaluating how organic fertilizers affect N and P mineralization rates in cool-season organic vegetable production systems.

In this free online course prepared by the Organic Agronomy Training Service (OATS), learn about weed control strategies for organic field crops commonly grown in the northern tier of the U.S. The course covers: strategies to prevent weed emergence; cultural and mechanical control strategies; and more.

The Organic Odyssey podcast is produced by Cal Poly San Luis Obispo students, bringing education about organic farming to everyone.

Manure and composted manure can improve Arizona's alkaline, low-organic-matter soils, but require careful management. This factsheet, produced by the University of Arizona Cooperative Extension, compares raw versus composted manure, nutrient chemistry, food-safety and pathogen risks, and application best practices, offering rate-calculation examples and a backyard guide for balancing crop nutrient needs against salinity and phosphorus buildup.

Join Ellie Andrews, UCCE Specialty Crops Advisor, in this informative webinar on cucumber beetles. Learn about cucumber beetle identification and integrated pest management (IPM) options, including cultural approaches and organic insecticide options.
