Variabilidade de atributos do solo sob pastagens e mata atlântica na escala de microbacia hidrográfica

Abstract: R E S U M OO solo é um dos recursos naturais de maior importância cuja heterogeneidade reflete na variabilidade de seus atributos químicos e físicos. Esta heterogeneidade é decorrente do processo de formação natural e do uso e manejo realizados pelo homem. Assim, o objetivo deste estudo foi avaliar a variabilidade espacial dos atributos químicos e físicos do solo e elaborar seus mapas de distribuição espacial na Sub-Bacia das Posses, Extrema. Para isto foram coletadas amostras em 150 pontos nas profundidades d… Show more

“…Under balanced conditions, the Atlantic Forest provides continuous benefits to the environment, contributing to climate regulation, nutrient cycling, maintenance of biodiversity, and genetic variability (Lima et al, 2014). Despite the important social, economic, and environmental functions of this biome, it has been reduced to only 8 % of its original area, making it crucial to adopt efficient conservation and recovery measures (Carvalhal et al, 2015).…”

“…Suas classes foram determinadas como baixa (CV ≤ 10 %), média (10 % < CV ≤ 20 %), alta (20 % <CV ≤ 30 %) e muito alta (CV > 30 %) (Pimentel Gomes & Garcia, 2002). O potencial hidrogeniônico (pH), apresentou coeficientes de variação baixo (5,91% a 3,80%) em ambas as profundidades, assim como os resultados encontrados por Lima et al (2014) onde o CV do pH foi de 8,5 trabalhando em um solo sob pastagem. Já a matéria orgânica (MO) com os CVs de 34,83 e 48,94 e o carbono orgânico (CO) com CVs de 34,40 e 51,20 foram classificados em muito alta nas duas profundidades corroborando com Lima et al (2014) que apresentou o teor de matéria orgânica com CV muito alta.…”

“…According to Araújo et al (2007), for the application of the model, a few basic assumptions must be made: the natural ecosystems, characterized by minimum anthropic intervention and expected equilibrium, are considered as a reference; two categories of soil quality attributes (chemical and physical) contribute equitably to soil quality and the same weighted value For SQI determination, the attributes involved in the main functions performed by the soil (Table 2) were considered. The analysis of soil chemical and physical attributes were performed by Lima et al (2014).…”
