It’s no secret that birds are facing many threats in our cities, but the leading cause of death may come as a surprise. It’s not avian flu or natural predators, but instead, outdoor cats.

Wrapping up #ONTAgWeek with one more #UofG student infographic!

Jessica Collier, BSc student in Integrative Biology, shares some tips for preventing algal blooms fed by runoff from farm fields 🌱 🐟

@uofgresearch.bsky.social @uofgcbs.bsky.social
The dos and don'ts for reducing nutrient runoff from fertilizer on farms. Harmful algal blooms occur in high nutrient areas. Harmful algal blooms can produce toxins and create low oxygen zones where they decompose that kills aquatic life. Fertilizer runoff is a major contributor of nutrients in aquatic systems. Don't apply fertilizer on frozen soil so it is not lost as runoff when frozen fields melt. Don't clear cut shoreline. Avoid removing all plants on shorelines to decrease nutrient runoff. Don't overapply fertilizer. Test your soil before applying fertilizer to prevent unneeded application. Do conservation tillage. Leave crop residues on your fields after harvest. Do reduce irrigation. Choose drip irrigation and try irrigating only when necessary. Do keep a natural shoreline. Keep a planted shoreline to help absorb nutrients in runoff.
