  • Importance of Soil & Water Testing
  • Soil Health Management
  • Integrated Nutrient Management practice
  • Balanced use of fertilizers
  • Fertilizer use efficiency
  • Fertigation
  • Methods of fertilizer application
  • Role of bio fertilizer & organic manures in soil fertility improvement
  • Problematic soil management
  • Organic farming and Composting technologies
  • Soil fertility management under drought condition
  • Drought management

2. Training programmes of innovative technologies conducted to Extension Functionaries for dissemination of technologies among the farmers

  • Soil fertility management strategies
  • Balanced fertilization with INM practice
