| Terra preta (TP) is a soil amendment which is enriched with powdered charcoal, with nutrient sources from organic residues, and that constitutes a resource to improve soils for sustainable land use systems (Glaser, 2007). Terra preta-dark soil is inspired by the highly successful historic practice of soil building in the Amazon and other parts of the world. This work involves a relatively unexplored topic: the comprehension of infiltration processes and soil water content characteristics in a sandy loam soil combined with different fractions of terra preta amendments. This analysis contributes to a better understanding of the relationship between fractions of charcoal in terms of terra preta content and soil water holding capacity. First, a physical... |
