The Bat Guano of Madagascar
|
|
Full of nutrients, the Bat Guano exceeds all other existing organic fertilizers.
It is characterized by its content of essential elements (N-P-K) more balanced, its high content of micro-organism and his organic matter contents higher.
Moreover, the bat Guano of Madagascar presents:
• A particular high percentage of phosphorus and calcium
• A less acid pH even close to neutrality (because of the presence of alkaline-earth metals: Ca and Mg)
