- MACRO-NUTRIENTS: The nutrients required in large quantities are known as macro-nutrients.
- MICRO-NUTRIENTS: The nutrients required in small quantities are known as micro-nutrients.
- Manure and fertilizers are the main sources of nutrient supply to crops. Organic farming is a farming system with minimal or no use of chemicals as fertilizers, herbicides, pesticides, etc. and with a maximum input of organic manures, recycled farm wastes, and bio-agents.
