A model of the water-holding characteristics of soil is needed to develop a systematic method for determining the value of organic C in soil. In the United States, available water-holding capacity (AWC) in soil is that water retained in soil between field capacity and the permanent wilting point; these limits are approximated by that water retained between two energy limits: −1500 matrix potential (hygroscopic and micropore water) and about −33 kPa matrix potential (capillary rise). The General… 
Effects of carbon on moisture storage in soils of the Wisconsin Central Sands, USA
Quantifying soil water storage is important for plant growth and agricultural production. This is particularly important in sandy soils because they are widely cultivated and prone to drought. We
Soil water availability for plants as quantified by conventional available water, least limiting water range and integral water capacity
There are different approaches to define the soil available water (SAW) for plants. The objectives of this study are to evaluate the SAW values of 12 arable soils from Hamadan province (western Iran)
A carbon-based method for estimating the wetness of forest surface soil horizons
The degree of wetness in forest surface soils has an effect on chemical and biological processes but is not easily measured. The high spatial variability in carbon (C) concentration creates high
The effects of soil organic matter on soil water retention and plant water use in a meadow of the Sierra Nevada, CA
Tuolumne Meadows is a groundwater dependent ecosystem in the Sierra Nevada of California, USA, that is threatened by hydrologic impacts that may lead to a substantial loss of organic matter in the
Relationship of soil water retention characteristics and soil properties: a case study from the Colombian Andes
Abstract: Differences in soil water retention (SWR) characteristics between soil types and the factors driving those differences provide important information for land management, particularly in
Reevaluating the effects of soil organic matter and other properties on available water-holding capacity using the National Cooperative Soil Survey Characterization Database
Soil organic matter (SOM) has been known to hold water and be an important factor in contributing to the available water-holding capacity (AWHC). Recently, however, there have been overestimates of
Impact of Effective Microorganisms (EM) Application on the Physical Condition of Haplic Luvisol
The study set out to determine changes in the soil air-water properties, the water-stable aggregate share and organic carbon content as effects of a five-year application of effective microorganisms
Available water capacity and organic carbon storage profiles in soils developed from dark brown soil to boggy soil in Changbai Mountains, China
The available water capacity (AWC) is the most commonly used parameter for quantifying the amount of soil water that is readily available to plants. Specific AWC and soil organic carbon storage
Organic waste recycling in agriculture and related effects on soil water retention and plant available water: a review
The decrease of organic matter content in agricultural soils is a problem of great concern to farmers around the world. Indeed, it lowers soil fertility that directly impairs agricultural crop
