Resumo
A densa floresta tropical de clima quente e úmido, de solos ácidos e de pouca fertilidade, é possuidor de faixas de terras escuras conhecidas como Terra Preta de Índio (TPI), formadas pela ação antropogênica dos homens que ali habitavam. A TPI fora formada pelo depósito nas circunvizinhanças dos resíduos produzidos no dia a dia da população. Esses resíduos continham restos vegetais, animal, cacos de cerâmica e além de muito material orgânico na forma de carvão originário da queima no preparo e manejo de áreas para o plantio e fogueiras utilizadas para o preparo da alimentação. Esses resíduos disposto ao solo amazônico, interagiram-se e modificaram o solo elevando demasiadamente sua fertilidade com considerável aporte de Ca, Mg, Zn, Mn, P e C. A comunidade cientifica mundial acredita ser principalmente a presença do carvão vegetal no solo (biochar), o principal elemento responsável pela grande melhoria de fertilidade.
The dense rainforest of hot and humid climates, with acidic soils and low fertility, possesses dark lands known as Terra Preta de Índio (TPI), formed by the anthropogenic action of the men who lived there. The TPI was formed by the deposit in the surroundings of the waste produced in the day to day of the population. These residues contained plant remains, animal remains, pottery chips and a lot of organic material in the form of charcoal from the burning for preparation and management of areas for planting and bonfires used to prepare food. These residues, disposed to the Amazonian soil, have been interacted with and modified the soil by elevating their fertility with considerable contribution of Ca, Mg, Zn, Mn, P and C. The world scientific community believes mainly the presence of charcoal in the soil (biochar ), The main element responsible for the great improvement of fertility.
