Variabilidade Espacial De Atributos Físicos Do Solo Em Área De Encosta Sob Processo De Degradação

Abstract: RESUMO: As condições físicas do solo são diretamente relacionadas com as práticas de manejo e o formato do relevo. A falta de manejo adequado pode levar os solos a processos erosivos e consequentemente degradação dessas áreas. Atualmente, estudos de variabilidade espacial permitem obter uma melhor análise para tomada de decisões e resoluções das referidas problemáticas. Pensando nisso, o presente estudo teve como objetivo avaliar a variabilidade espacial da infiltração de água no solo, densidade do solo e text… Show more

“…A number of studies, including Lima et al (2015) and Araújo et al (2014) reported that the variability of physical and hydraulic properties of the soil shows correlation or spatial dependence. Because of this, several geostatistical tools are used to study the spatial variability of soil attributes and can potentially lead to management practices that allow a better understanding of the interaction between the soil-plant-atmosphere system (Lemos Filho, 2010).…”

“…O coeficiente de variação (CV) indicou média variabilidade (CV de 12% a 60%) para argila e silte, e baixa variabilidade (CV<12%) para areia total, nas três amostragens estudadas (WARRICK; NIELSEN, 1980). Assemelhando-se aos resultados obtidos por Lima et al (2015) e Tavares et al (2012), os quais observaram média variabilidade para argila e silte, e baixa variabilidade para areia. No entanto, Souza et al (2014) verificaram baixa variabilidade para argila e areia nas diferentes densidades amostrais.…”

“…This may have occurred due to the joint action of several factors such as soil texture and water infiltration, which vary according to the different hillside positions (Lima et al, 2015). In addition, soil K concentration (> 0.40 cmolc dm −3 ), which is considered as high (Faria et al, 2007) and its relative mobility in the soil profile (Souza et al, 2012;Duarte et al, 2013), associated with variations of organic matter content and CEC in the different soil layers (Table 1), may have been important in this interaction.…”

“…Hillside areas are especially susceptible to degradation, mainly when used for olericulture due to an intensive soil management and use of agricultural inputs in this activity (Lima et al, 2015;. There are reports that the lower the technological level of agriculture is, the greater the potential for degrading the agricultural environment (Stefanoski et al, 2013).…”
