Distribuição espacial do efluxo de CO2 em área de terra preta arqueológica sob cultivo de cacau e café no município de Apuí, AM, Brasil

Abstract: As Terras Pretas Arqueológicas (TPA) são solos que podem concentrar até seis vezes mais carbono orgânico que solos adjacentes sem horizonte A antrópico, presumindo-se, dessa forma, maior efluxo de CO2 nesses solos. O objetivo deste estudo foi investigar a distribuição espacial do efluxo de CO2, temperatura e umidade do solo em área de Terra Preta Arqueológica sob cultivo de cacau e café no município de Apuí, AM, Brasil. Foram construídas malhas amostrais nas dimensões 42 x 80 m, com espaço entre os pontos de 8… Show more

“…However, this can be explained with the process of C cycling from plant residues to the soil, which occurred with less intensity under natural conditions (forest) than under cultivated conditions (cacao and coffee). Furthermore, according to Campos et al (2016), factors such as the stability of crop cultivation systems, crop spacing, accumulation of leaf litter, and supply of organic C affect the amount of C stored in the soil of cacao and coffee areas.…”

“…Many studies have verified the existence of spatial dependence structures applying geostatistical analyzes to assess the spatial behavior of IBEs attributes in Amazonas (Brito et al 2018;Campos et al 2016;Cunha et al 2019;Gomes et al 2017;Oliveira et al 2014;Soares et al 2015). This technique not only allowed the evaluation of the aspects of spatial variation of the soil properties, but also guaranteed a good interpolation of the data and the generation of isoline maps with accuracy to better indicate the management zones.…”
