Peruvian Seabird Guano is one of the most potent natural nitrogen sources available — rivalling blood meal at 14.6% nitrogen, but in a mineralised form that's entirely unique due to the age and composition of this decades-old Peruvian deposit. We're big fans of this ingredient and use it across our soil blends and fertilisers, so we've secured enough supply to offer it as a standalone raw amendment as well.
In contrast to our High P/Si Seabird Guano, this Peruvian source packs a serious nitrogen kick alongside balanced phosphorus and potassium, substantial calcium, and a broad spectrum of trace minerals including iron, zinc, manganese, boron, copper, cobalt, and molybdenum. It also provides chitin, delivering the same SAR-triggering immune benefits found in other chitin-bearing amendments. The result is an exceptionally versatile, mineral-dense soil food that corrects deficiencies, improves soil structure and drainage, and lifts overall plant health and productivity.
