What is the difference between organic and other kinds of farming?

 A main difference between organic and other kinds of agriculture is that organic farming is a holistic production management system, aiming at maintaining or enhancing soil fertility and biological activity. Organic farming is based on locally adapted management practices in preference to the use of off-farm inputs or no management at all. In comparison with many other environmentally-friendly farming systems, organic farming differs in the sense that standards and certification systems are very well developed and internationally widespread.
