Effect, Bombax ceiba, Guano, Phalacrocorax niger.Abstract
The guano is the white faecal matter of birds, which is excreted in the forms of droppings or powders. The guano contains uric acid, C5H4N4O3, which sticks to the branches, leaves, trunks of the tree and vegetation under it when the birds roost on trees and excrete, where once it has dried, it is very difficultly removed. Although, it is washed into the soil by rain. The guano of Phalacrocorax niger affected Bombax ceiba trees adversely making them extremely white, leafless, flowerless and fruitless, during their peak time of blooming and fruiting, while the unaffected trees were found to be normal in colour, leaves, flowering and fruiting.References
