Agricultural production in the arid and semiarid regions of the world is limited by poor water
resources, limited rainfall, and the detrimental effects associated with an excess of soluble …

Publisher Summary This chapter reviews some new research in green manuring of wetland
rice. It discusses the agronomic advantages of applying green manures to wetland rice as a …

Ammonia (NH 3) volatilization is a major pathway of nitrogen (N) loss in agricultural systems
worldwide, and is conducive to low fertilizer N use efficiency, environmental and health …

Incorporation of urea decreases ammonia (NH3) volatilization, but field measurements are
needed to better quantify the impact of placement depth. In this study, we measured the …

The mineralization of N in salt-affected soils is a subject of much controversy because there
are reports of salt induced non-biological ammonification. In laboratory experiments we …

Archaeological predictive modeling has been used successfully for over 20 years as a
decision-making tool in cultural resources management. Its appreciation in academic circles …

This volume covers such areas in the field of soil salinity and water quality as: origin and
distribution of salt-affected soils; management of alkali soils; quality criteria of irrigation …

Many of the arable soils in Australia are affected by salinity and/or sodicity. Nutrient
deficiency and ion toxicity may occur in both saline and sodic soils. Ho-ever, the mechanism …

Concerns about ammonia (NH 3) losses from nitrogen (N) mineral fertilizers have forced
policymakers to set emission reduction commitments across Europe. Although best …

The adoption of modern agricultural technologies has revolutionized food grain production
bringing it up to levels to feed the quickly growing population of the world. Worldwide there …
