Guano consists of ammonia, along with uric, phosphoric, oxalic, and carbonic acids, as well as some earth salts. Guano also has a high concentraion of nitrate. Currently vast volumes of phosphorus are needed to produce fertilizer, as it is an essential plant macro nutrient. Guano is rich in phosphuros and is an intensely effective and environentaly friendly phosphorus fertilizer. Our guano is harvested by hand from a pristine enviroment in the Zimbabwe midlands. Enviromental impact is minimised by using no machinery at all as all our guano is harvested by hand only at night to minimise impact on the bat population. Full nutrient analysis and pathology available.
