Natural fertilizers

The basic rules of organic production are that natural inputs are approved and synthetic inputs are prohibited, althouth there are exceptions in both cases. Soil-building crop rotations are also essential to organic production, with management techniques such as intercropping, double-digging, mulching and integration of crops and livestock playing a vital part. Compost is cheap and locally available. It restores soil structure, improves water retention, and enhances high yield over time because it has a wide range of nutrients.
