Irrinet-Sardegna: an internet/intranet interactive irrigation management system

摘要

Irrinet-Sardegna is a new internet/intranet interactive tool for irrigation assistance, developed with the purpose to rationalize the irrigation use of water, in way to give to the farmers specific information regarding volumes and time scheduling of irrigation. Irrinet-Sardegna was realized in collaboration between Servizio Agrometeorologico Regionale per la Sardegna, Consorzio della Bonifica Renana, Consorzio del Canale Emiliano-Romagnolo and Ente Regionale di Sviluppo ed Assistenza Tecnica - ERSAT. The system is based on a soil water balance model, which calculates, starting from a fixed date (e.g. the date of last irrigation) and until four days after the actual date, with a daily time step, the actual water capacity (AWC). Various soil properties, plant development stages, irrigation system characteristics, meteorological data and plant water uptake are used as the main input parameters in the model. The output is displayed on a web page which includes information and data both in test and numerical form concerning the main elements of soil water balance (e.g. evapotranspiration, rain, AWC, etc.) and the date and volumes of suggested irrigation. Irrinet-Sardegna is one part of a large set of information, data, services and forecasts, whichthe Servizio Agrometeorologico Regionale per la Sardegna presents daily on its web site to support local farmers.
