Human carcinogenicity of inorganic arsenic,umerous laboratory studies have provided useful information on the factors affecting denitrification in soils but these findings cannot be used to predict the extent of denitrification in the field. In recent years, increased interest in the efficiency of nitrogen (N) use in agriculture and the impa

The Physiology of Arsenic in Rice,direct field measurements have been made of the exchanges of nitrogenous gases between soils, plants and the atmosphere. Methods of three general kinds have been employed: those using diffusion theory to calculate gas transport in the soil profile; enclosure methods in which the flux density of the

Arsenic Contamination in the Environmentase the efficiency of N added to the system through biological and industrial fixation. Of the many pathways of loss, those from plants have in the main been ignored, or were thought to be extremely low (Allison 1955, 1966). Recently, however, Wetselaar and Farquhar (1980) have reviewed data that su

The purpose of the present review is to deal mainly with NH. volatilization losses from manures and sewage sludges as affected by climatic and soil factors. Information on NH. volatilization from othe

Arsenic in Latin America: Part I,lizer N production has increased from 3.6 × 10. t in 1970 to an estimated 18 × 10. t in 1982/83, of which 85% will be urea (Stangel 1979). Expanded use of N fertilizer is being combined with fertilizer-responsive rice varieties and increased areas under irrigation in an all-out effort to produce eno
