An integrated, multisensor system for the continuous monitoring of water dynamics in rice fields under different irrigation regimes

摘要: The cultivation of rice, one the most important staple crops worldwide, has very high water requirements. A variety irrigation practices are applied, whose pros and cons, both in terms productivity their effects on environment, not completely understood yet. continuous monitoring rainfall inputs, as well soil dynamics, is a factor analysis these practices. At same time, however, it represents challenging costly task because complexity processes involved, difference nature magnitude driving variables field conditions. In this paper, we present prototype an integrated, multisensor system for dynamics rice fields under different regimes. consists following: (1) flow measurement devices supply tailwater drainage; (2) piezometers groundwater level monitoring; (3) gauges flooding depth; (4) multilevel tensiometers moisture sensor clusters to monitor status; (5) eddy covariance station estimation evapotranspiration fluxes (6) wireless transmission software interface data transfer, storage control from remote computer. modular replicable It was successfully applied over 2-year period three experimental plots Northern Italy, each with management strategy. information concerning instruments selected, interconnections integration common scheme. We also provide considerations figures material labour costs installation system.
