dc.description.abstractPhosphorus (P) is one of the nutrients that most limits agricultural productivity, especially in tropical soils. Enriched biochar has been proposed to increase the bioavailability of P and other nutrients in the soil. Thus, the objective of this study was to evaluate the availability of P in phosphate biochar (composed of biomass and soil) as a function of the triple superphosphate mixture before and after the pyrolysis process. We produced eight types of enriched biochar via pyrolysis by combining sandy or clayey soil with rice or coffee husk, and by adding triple superphosphate before or after pyrolysis. The heating of the phosphate fertilizer during the pyrolysis process resulted in a higher crystallinity of the phosphates, lower content of labile fractions of P and lower content of available P in phosphate biochars than when the superphosphate was added after pyrolysis.
dc.description.abstractO fósforo (P) é um dos nutrientes que mais limita a produtividade agrícola, principalmente em solos tropicais. Biocarvão enriquecido tem sido proposto com o intuito de incrementar a biodisponibilidade de P e de outros nutrientes no solo. Assim, objetivou-se avaliar a disponibilidade do fósforo em biocarvão fosfatado (composto de biomassa e solo) em função da mistura de superfosfato triplo antes e após o processo de pirólise. Produzimos oito tipos de biocarvão enriquecido via pirólise, combinando solo arenoso ou argiloso com casca de arroz ou de café, e adicionando superfosfato triplo antes ou depois da pirólise. O aquecimento do fertilizante fosfatado durante o processo de pirólise resultou em maior cristalinidade dos fosfatos, menor teor de frações lábeis de P e menor teor de P disponível nos biocarvões fosfatados do que quando o superfosfato foi adicionado após a pirólise.
