Última Role of charcoal addition on infiltration processes and soil water content characteristics of a sandy loam soil CIGR Journal Villagra-Mendoza, Karolina. 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...

Ano: 2017 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/3770 Simulated effect of wetting/drying periods for two textural soils amended with biochar at a catchment scale CIGR Journal Villagra-Mendoza, Karolina; Carvajal-Vanegas, Dorian; Beck-Broichsitter, Steffen; Horn, Rainer. Biochar is considered as an option to ameliorate soil functions, by improving soil physical and hydraulic soil properties. This study investigated the effect of biochar and of wetting and drying cycles on the water infiltration at laboratory and at a hypothetical watershed scenario. In the laboratory, test samples with 2.5 and 5% (by dry mass) of a mango-wood biochar were added to a sandy and sandy loam soil material. Cumulative infiltration was determined after simulated intense wetting and drying cycles, by drying the samples at 30°C for three consecutive days. Additionally, biochar amended soil hydraulic parameters, obtained at the laboratory, were used to simulate the water discharge of a hypothetical watershed, with the Soil and Water Assessment Tool...
