Approx. 30,000 ha of simple plastic greenhouses is located along the SE Spanish Mediterranean coast. The main crops are tomato, pepper and melon. Approx. 80% of cropping takes place in soil, the rest in hydroponic systems. Recent studies have evaluated N and irrigation management, and measured nitrate (NO3-) leaching loss. A synthesis of results from these studies identifies the management factors mostly responsible for the appreciable ...
