Changes in Water Infiltration after Simulated Wetting and Drying Periods in two Biochar Amendments

摘要: Biochar impacts soil-water related processes such as infiltration and contributes to the hydrological response of catchments. The aim this work is determine impact wetting drying conditions on behavior two biochar amendments validate performance three models: Kostiakov, Horton, Philips. Two materials, sand a sandy loam, were mixed with 0%, 2.5%, 5% (by dry wt.) mango wood produced at highest heating rate 600 °C particle size <63 μm. A sequence four cycles simulated. In each cycle, was measured. We found that addition decreased because formation narrower pores reduced capacity. higher dosage, more resilient treatment became concerning changes water infiltrated. Repetitive resulted in reconfiguration structural affecting transport air. models Kostiakov Horton could predict dynamics amended although they show some instabilities along WD cycles.
