Sinposis

ONE OF THE MAIN APPROACHES FOR SAFEGUARDING FOOD SECURITY, SUSTAINABLE DEVELOPMENT HAS INCREASED DEMAND FOR KNOWLEDGE ON FERTILIZER MANAGEMENT IN CROP PRODUCTION. AMONG ESSENTIAL PLANT NUTRIENTS, NITROGEN IS ONE OF THE MOST IMPORTANT YIELD-LIMITING NUTRIENTS, MAINLY RESPONSIBLE FOR DETERMINING YIELD AND YIELD COMPONENTS IN CEREALS AND LEGUMES. IT IS ALSO RESPONSIBLE FOR THE ACTIVATION OF MANY ENZYMES AND, OF COURSE, PLAYS AN IMPORTANT ROLE IN PHOTOSYNTHESIS. WITH A RECOVERY EFFICIENCY OF LESS THAN 50 PERCENT IN MOST CROPPING SYSTEMS, A LARGE PORTION OF THE NITROGEN APPLIED AS FERTILIZER IS NOT USED BY PLANTS, CREATING ENVIRONMENTAL AND ECONOMIC ISSUES.
