Abstract: ResumoOs indicadores convencionais de fertilidade de solo, mais comumente utilizados, enfatizam o balanço ácido-base e o conteúdo de elementos químicos, mas não consideram adequadamente as propriedades biológicas do solo, responsáveis por grande parte do seu funcionamento. Os indicadores biológicos, ainda pouco difundidos, levam em consideração a atividade microbiana do solo que é mais sensível à dinâmica do solo. Em Marapanim-PA, e utilizando um desenho experimental inteiramente casualizado, com quatro repeti… Show more

“…In this study, carbon concentrations ranged from 0.49 (wet combustion) to 2.48 dag kg -1 (loss-on-ignition), staying within the variation range for soils of the Amazon (DESJARDINS et al, 2004). Other studies carried out in the same region found C concentrations, analyzed by wet combustion, ranging from 1.2 to 1.4 dag kg -1 in 18-monthold successional forest soils and from 0.8 to 1.8 dag kg -1 in alternative cropping system (ARAGÃO et al, 2012); and from 0.92 to 2.61 dag kg -1 , at the 0-25 cm layer, in slash and burn and chop and mulch systems, using the dry combustion method (COMTE et al, 2012).…”

“…The rainiest season caused a rise in C SMB in all planting areas (Table 2). Aragão et al (2012) and Silva et al (2016) also found increases in C content in biomass during the rainiest season. This may be associated with an increase in nutrient availability with increasing precipitation as well as a decrease in aluminum saturation.…”

“…Brazilian experiences have shown positive effects using legumes as Canavalia ensiformis, Chamaecrista rotundifolia, Acacia mangium, Inga edulis and Cajanus cajan for soil reclamation [6] [7] [8], improving maize [9] and cassava (Manihot esculenta) productivity [10].…”
