Última Soil hydrophobicity: comparative study of usual determination methods Ciência Rural Vogelmann,Eduardo Saldanha; Reichert,José Miguel; Prevedello,Juliana; Awe,Gabriel Oladele; Reinert,Dalvan José. Hydrophobic or water repellent soils slowly absorb water because of the low wett ability of the soil particles which are coated with hydrophobic organic substances. These pose significant effects on plant growth, water infiltration and retention, surface runoff and erosion. The objective of this study was to compare the performance of tension micro-infiltrometer(TMI) and the water drop penetration time (WDPT) methods in the determination of the hydrophobicity index of eighteen soils from southern Brazil. Soil samples were collected from the 0-5cm soil layer to determine particle size distribution, organic matter content, hydrophobicity index of soil aggregates and droplet penetration time of disaggregated and sieved soil samples. For the TMI method the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Water repellency; Water drop penetration time; Water infiltration..
