Decomposição Da Serapilheira Foliar E Respiração Edáfica Em Um Remanescente De Caatinga Na Paraíba

Abstract: 4Resumo -A serapilheira é uma das principais fontes de transferência de nutrientes para o solo, assumindo preponderância no processo de ciclagem de nutrientes em ecossistemas florestais. O trabalho teve por objetivo analisar a decomposição de uma mistura foliar de 10 espécies da Caatinga, em paralelo com a respiração edáfica. O estudo foi realizado no Sítio Riachão, localizado no Município de Pombal, PB. A taxa de decomposição foi determinada por medidas de perda de massa, com o auxílio de sacolas de náilon (2… Show more

“…Differences between CO 2 evolution during the day and the night may be caused by lower night temperatures, which would result in higher relative humidity and, consequently, higher soil microbial activity (Souto et al, 2009;Holanda et al, 2015). However, no differences were found between day and night in either of the two methods (Table 2).…”

“…Measurements performed in other Caatinga areas (Souto et al, 2009;Correia et al, 2015;Holanda et al, 2015), all of them using the AA methodology, registered small (0.28 µmol CO 2 m -2 s -1 ) and high amplitudes (0.75 µmol CO 2 m -2 s -1 ) between maximum (1.00 to 1.32 µmol CO 2 m -2 s -1 ) and minimum values (0.57 to 0.72 µmol CO 2 m -2 s -1 ). It is not possible to know if the similarity of ECO 2 values throughout the year, reported by some of these articles, was due to absence of environmental variables that substantially altered root respiration and soil microbial activity, or if it was caused by a limitation of the methodology.…”
