ALTERATION OF NITROGEN CYCLING BY AGRICULTURAL ACTIVITIES, AND ITS ENVIRONMENTAL AND HEALTH CONSEQUENCES

The food demands of the increasing world population puts pressure on land use and N availability. In this paper an overview is given of the different N cycling processes affected by agricultural activities. Of the amount of N added to the soil, about half is removed from the field as harvested crop,...
