Organic Wastes Management for Improving Crop Yields and Environmental  Quality

Background

Soil organic carbon  →  critical role in terrestrial C cycle, preserving soil quality, food security and environmental protection in agro ecosystems

• Continuous intensive cereal based cropping system
• Unbalanced use of fertilizers
• Adverse soil physical and chemical conditions
• Low water Use Efficiency →

Important  factors for  low crop yield, sustainability of soil fertility and  environmental degradation

}Water resources shrink → challenge → to produce more food with less water

}One of the most important tools for reducing pressure on all of the nation’s water resources is improving the efficiency of water use

}Improving water management in agriculture → crucial for increased food security
