Guano, an organic fertilizer but also a harmful substance if for example it is pigeon. Let's see how it can be used in such a way virtuous and green, and how it can manage to damage the environment and also the health of those who come into contact with it.
Guano: what it is
Exactly as droppings and manure, even guano is a fertilizer that is obtained from animal manure. In particular, the fertilizer guano is obtained from seabird droppings, it is usually found in countries such as Chile and Peru, in areas where this droppings have accumulated and then dried forming real "deposits" of green fertilizer.
Guano: organic fertilizer
In the field of fertilizers, gardening and agriculture, guano is considered one of the 100% organic natural fertilizers. When in fact you want to talk about biological agriculture, using it is allowed. If we ourselves want to grow only organic vegetables, we can rely on this product certain that it is completely natural.
When it is necessary to fertilize the soil, you take this mix of bird droppings and distribute it, during the vegetative phase of plants because it is a ready-to-use organic fertilizer. This means that it is able to provide the substances that the earth needs. As soon as it comes into contact with it, it makes them available with the horticultural plants that need to develop.
Guano: fertilizer for the garden
If not we have hectares and hectares of fields to cultivate but “only” our home garden, nothing prevents us from using guano. It can be distributed as needed even without preparing the soil long before, since this substance contains nitrates in abundance but they they wash easily with the rains.
It cannot be distributed randomly, or with unmotivated generosity, in the land, whether it is a small home garden or an extensive plantation. Guano is in effect a very rich fertilizer in nutritional macroelements such as phosphorus, nitrogen and potassium, and therefore with the doses, you can not go in spans. There is a risk of causing damage and lowering the productivity level of our plants.
The guano of pigeons it is not as beneficial as that of other seabirds we have talked about so far. It is actually at the root of some health and hygiene problems, and more. The pigeon droppings they cause real damage to structures and buildings, to monuments but also to normal homes that are "corroded" by this substance.
Therefore a effect of decay and dirt which forces many administrators and many individual citizens to defend attics, eaves, vaults, windowsills, cornices "attacked" by the excrement of pigeons. Not only that: in addition to this, the excrements carry pathogens and parasites just like the remains of dead birds, bacteria can then expand freely in the air "polluting" it.
The guano of pigeons renders places and objects, contaminants and also serious pathologies for us humans and animals can result. Among the infectious diseases that can be transmitted by guano, salmonellosis, ornithosis, borrelliosis, toxoplasmosis, encephalitis, tuberculosis ...
The bat guano it has characteristics similar to that of birds which are usually indicated as the major producers of this type of fertilizer, such as gulls, cormorants and other marine birds. Even though they are mammals, bats produce droppings similar to those of penguins and other birds.
To experience it in our garden, we can buy a lot of fertilizer on Amazon for 8.60 euros also rich in magnesium and sulfur, suitable for enriching the soil with natural substances that are easily assimilated. Usually this type of fertilizer is recommended when you are growing vegetables or fruit.
In granules or in dry pellets, ready for distribution on the garden land, on the market this fertilizer is found in agricultural centers or nurseries.
