Islands’ seabird guano is a powerful natural fertilizer—unique in the word—that results from the accumulation of droppings of seabirds living on the islands and wave-cut cliffs of the Peruvian littoral zone, such as Guanay cormorants, Peruvian boobies, and Peruvian pelicans, among others. The natural relation of birds hunting fishes with very high omegas. We can say that there are 5 million small birds’ factories, well protected as natural reserves and with very strict policies to preserve the spices. The guano’s power as a fertilizer is mainly due to two factors: the proper nutrition of guano birds—which mostly eat anchovies—, and the guano’s maturing time, which is only collected after 5 to 7 years of being on the islands. During that time, nutrients present in the manure become elements increasingly simpler and easier to assimilate for plants. Laboratory tests indicate that guano has a wealth of nutrients which cannot be found in synthetic fertilizers. Furthermore, thanks to the microorganisms and the organic matter it provides, it does not only strengthen the vitality of the soil, but also imparts looseness to it, which retain water as a sponge, which plants benefit from according to their needs. To preserve the purity of its original composition, seabird guano is collected, sieved, weighed, and packed in its same place of origin. This way, the entrance of external elements is prevented and a concentration of essential nutrients higher than that of the manure of farm animals or of other organic fertilizers is guaranteed.
