Métodos de preparo de solo e sua influência na erosão hídrica e no acúmulo de biomassa da parte aérea de Eucaliptus Saligna em um cambissolo háplico da depressão central do Rio Grande do Sul

Abstract: Este estudo buscou identificar e quantificar o efeito de métodos de preparo de solo e manejo de resíduos da colheita sobre a erosão hídrica e o desenvolvimento inicial da floresta de Eucalyptus saligna em um Cambissolo háplico. O ensaio foi instalado em área experimental da Aracruz Celulose e Papel S. A., localizada no Município de Arroio dos Ratos, na região fisiográfica denominada Depressão Central. O delineamento experimental utilizado foi o de blocos ao acaso com três repetições. Os tratamentos testados fo… Show more

“…These results are in agreement with those of Wichert (2005) and Baptista and Levien (2010), according to which subsoiling in the declivity direction increases erosion compared to the manual opening of grooves on the ground. The losses verified annually, although high from the point of view of the environmental preservation outside the place of origin of erosion, were low as to the maintenance of the studied soil productive capacity, compared to the tolerance of this type of soil, which is around 9 Mg ha -1 year -1 (Bertol and Almeida, 2000).…”

“…Specifically, Smith et al, 2005 indicated that the improvements of subsoiler were strongly affected by soil type, soil condition, and soil water content at the time of site preparation. On the other hand, the most intensive tillage system such as subsoiler increases the amount of bare soil until canopy closure and therefore increases soil erosion risk (Worrell and Hampson, 1997;Baptista and Levien, 2010). Therefore, it is necessary to establish soil tillage systems with high production levels for each soil condition, while minimizing negative environmental impacts (Binkley et al, 2004;du Toit and Dovey, 2005).…”
