Global interest in soil health has increased exponentially during the past decade, with many
different government, non-government, and private sector groups striving to develop …

For the last 50 years, the consensus view among researchers has been that organic matter
(OM) has little or no effect on the available water capacity (AWC) of soil. The historical …

The current and projected anthropogenic global warming and the attendant increase in the
severity and extent of soil degradation may exacerbate the intensity and duration of drought …

Agriculture is a source for three primary greenhouse gases (GHGs): CO2, CH4, and N2O. It
can also be a sink for CO2 through C sequestration into biomass products and soil organic …

Soil organic carbon (SOC) in arable topsoil is known to have beneficial effects on soil
physical properties that are important for soil fertility. The effects of SOC content on soil …

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 …

The effects of mineral fertilizers and organic amendments on soil properties, carbon (C)
sequestration, and crop yields are studied in a 37‐year field experiment, Phosphorus …

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 …

Soil physical quality (SPQ) is assessed by comparing values of “indicator” soil properties (eg
bulk density, air capacity) to “ideal ranges” established in the literature. These ideal ranges …

Nitrogen (N) and precipitation are the main limiting factors in food production under rain-fed
cropping systems in arid and semiarid regions. A long-term field experiment was conducted …
