Coop Poop organic fertilizer by Healthy Grow is naturally packed with the essential nutrients your soil needs to grow hearty, healthy plants. This Aerobically Composted Chicken Manure (ACCM) is high in calcium for strong plant tissue development and disease resistance, while also improving photosynthesis, nutrient uptake and starch conversion. Plus, Coop Poop is virtually odor-free compared to the pungent scent normally associated with other manure-based composts. But don’t just take our word for it. Coop Poop is also backed by years of reliable university research and has consistently outperformed other organic alternatives available.
