Organic Fertilizer

Bat Guano

ABG Phosphate is 100% natural and organic and is OMRI listed and USDA certified for use in the production of organic food and fiber.  ABG phosphate really is the best phosphate and micronutrient fertilizer available.

4. Superior results and exceptionally safe compared to other organic and synthetic phosphate fertilizers that may contain uranium and other potentially toxic material, including "Mad Cow" and high fluoride concentrations

6. History shows guano is the organic fertilizer with the most mystique
7. No foul odor
