Abstract: Our study aimed to evaluate the influence of rubber tree plantations (Clones IAN 873 and FX 3864) on microbial activity, total organic carbon (TOC), and soils chemical attributes, using as reference pasture and secondary forest, in Rio de Janeiro. The plantations areas showed pH; Mg 2+ , Ca 2+ , K + levels; sum of bases; base saturation, basal respiration; metabolic quotient; and arylsulfatase and FDA activities in the soil similar to or greater than the values found in the forest. In contrast, showed lower P … Show more

“…Positive correlation between soil respiration and C, N, and P contents in soil is consistent with the results from other studies (Fan et al, 2015; Guo et al, 2016; Wang et al, 2013). In addition, other studies have also shown the negative effects on soil ecosystem functions resulting from the conversion of natural forest via the reduction of soil enzyme activities (Diniz et al, 2020; Nurulita et al, 2016). Specifically, C (β‐glucosidase and cellobiohydrolase) and P (acid phosphatase) acquisition enzymes, as well as a lignin‐modifying enzyme (laccase), significantly decline in rubber plantations compared to natural forests (Figure S6).…”

“…Basal respiration (BR) was determined following the alkali absorption method for quantification of CO 2 evolution (Cheng et al, 2013;Diniz et al, 2020;Meena and Rao, 2021). In brief, a 20 g air-dried soil sample was adjusted to 60% of its waterholding capacity by adding water and pre-incubated at room temperature (25 °C) for 7 days.…”
