About this book
This volume presents the results of the project "Ecology of Arable Land. The Role of Organisms in Nitrogen Cycling." The project was carried out during 1979-1988 with field studies concentrated to 1980-1985. The main project objective was to investigate and synthesize the contributions of the soil organisms to nitrogen and carbon circulation in four contrasting cropping systems. More than 25 scientists, from disciplines including soil hydrology, crop production ecology, soil microbiology, soil zoology, soil chemistry and systems analysis, were involved in the project.
