Irrigation systems for agriculture in Southern Italy. Selection rules for sustainable agriculture.

摘要

In hot-dry environments, where water is often lacking and crop yields are limited, the choice of crop irrigation method is critical both for its sustainability and economic suitability. The main irrigation systems (lateral furrow flow, sprinkler anddrip irrigation and subirrigation) used in southern Italy on herbaceous crops are described. The technical characteristics and the advantages and disadvantages of these irrigation systems are highlighted. These principles are based on farm organization,crop requirements, environment (soil and climate) and water supply.
