“…Some studies (Tenge et al, 1998) show this trend during the day but an opposite trend overnight. Moroizumi and Horino (2002) found higher values of soil temperature under a CT treatment. The tillage depth under CT makes the soil more porous, and as a result, the soil likely has lower thermal conductivity (Sarkar and Singh, 2007).…”

“…Most of these changes also occur due to cultivation (Poulenard et al, 2001;Buytaert et al, 2002). Further problems related to Andosol cultivation are erosion (Neall, 1985), crust formation (De Noni et al, 2000), lower organic matter content and a decrease in soil moisture (Higuchi and Kashiwaga, 1993;Moroizumi and Horino, 2002). Other reported changes in hydrodynamic behaviour are increasing surface runoff, decreasing infiltration (Neall, 1985), development of larger pores and of preferential flow paths, and a decrease of the terrain roughness (Basile and De Mascellis, 1999;Poulenard et al, 2001).…”

“…Organic matter content generally decreases when Andosols are cultivated (Higuchi and Kashiwaga, 1993;Moroizumi and Horino, 2002). Therefore, the observed available water increase is likely a temporary phenomenon, as ploughing and harrowing activities increase the total pore content of the soil.…”

Abstract:The south Ecuadorian Andean mountain belt between 3500 and 4500 m altitude is covered by a highly endemic and fragile ecosystem called páramo. The Histic Andosols covering this region have highly developed hydric properties and exert a key function in the hydrological regulation of the páramo ecosystem. Unlike most Andosols, their extreme water retention capacity is not due to the presence of typical minerals such as allophane or imogolite. Although these minerals are virtually absent, the large organic carbon content, due to organometallic complexation, gives rise to similar properties. The water content at 1500 kPa can exceed 2000 g kg 1 , and the high hydraulic conductivity at saturation (about 15 mm h 1 ) drops sharply when low suction is applied. The three methods applied, i.e. the inverted auger hole, the tension infiltrometer and the constant-head permeameter method, give very similar results. The páramo is characterized by a slow hydrological response and a good water regulation, caused by the combination of a high water storage capacity and high conductivity. The wide pore size distribution of the organometallic complexes results in a water retention curve that differs significantly from the classic Mualem-Van Genuchten description, but can better be described with a simple linear or semilogarithmic model. The soils investigated are very prone to irreversible structural changes caused by land-use changes. The conversion of natural land for cultivation has a large impact on the hydrological function of the region. The water storage capacity increases by 5 to 30%, and the hydraulic conductivity is 31% higher in cultivated catchments. These changes are related to a larger peak flow, a smaller base flow and generally a smaller discharge buffering capacity, despite the higher storage capacity.

“…To determine the hydraulic properties of the soil (e.g., hydraulic conductivity, water retention), additional knowledge, such as the packing of the soil particles and the pore size distribution, is necessary. Knowledge on how the properties of the soils are controlled by factors such as PSD, mineral composition, or compaction conditions is important in various applications when certain properties need to be derived, for example, hydraulic or thermal characterization of synthetic soil liners for landfills (e.g., Garga and Madureira, 1985; Fragaszy et al, 1990; Shelley and Daniel, 1993), backfill for soil borehole thermal energy storage systems (e.g., Ohga and Mikoda, 2001), and agricultural soils affecting productivity (e.g., Moroizumi and Horino, 2002).…”

The mixing of different sized soil particles is known to affect soil properties such as density, porosity, hydraulic conductivity, and soil water retention. To better understand how the mixing controls soil water retention characteristics, a set of laboratory experiments was performed using binary mixtures of coarse and fine particles with seven different mixing fractions. For each mixture, the water retention characteristics, porosity, and saturated hydraulic conductivity were obtained. To enhance the effects of mixing, coarse and fine sands with a relatively large particle size contrast were used. Results showed that at equal to or above the fine fraction of ∼0.3, the fine particles controlled the behavior. Starting from the fine‐only sample, introducing more coarse particles to the fine particles led to rather gradual changes in the water retention characteristics. Wall effects at the coarse–fine particle interfaces were presumed to be responsible for the changes in the water retention curves. The water retention curves for the mixtures with a fine fraction lower than 0.3 were controlled by the coarse particles yielding the displacement pressure similar to that of the coarse sand. Furthermore, it was inferred that different mixing fractions led to different spectra of pore sizes, suggesting that a parametric model with sufficient flexibility is needed to describe the water retention characteristics of binary mixtures.
