Environmental Monitoring and Assessment | Year: 2015

The cultivation of rice, one of the most important staple crops worldwide, has very high water requirements. A variety of irrigation practices are applied, whose pros and cons, both in terms of water productivity and of their effects on the environment, are not completely understood yet. The continuous monitoring of irrigation and rainfall inputs, as well as of soil water dynamics, is a very important factor in the analysis of these practices. At the same time, however, it represents a challenging and costly task because of the complexity of the processes involved, of the difference in nature and magnitude of the driving variables and of the high variety of field conditions. In this paper, we present the prototype of an integrated, multisensor system for the continuous monitoring of water dynamics in rice fields under different irrigation regimes. The system consists of the following: (1) flow measurement devices for the monitoring of irrigation supply and tailwater drainage; (2) piezometers for groundwater level monitoring; (3) level gauges for monitoring the flooding depth; (4) multilevel tensiometers and moisture sensor clusters to monitor soil water status; (5) eddy covariance station for the estimation of evapotranspiration fluxes and (6) wireless transmission devices and software interface for data transfer, storage and control from remote computer. The system is modular and it is replicable in different field conditions. It was successfully applied over a 2-year period in three experimental plots in Northern Italy, each one with a different water management strategy. In the paper, we present information concerning the different instruments selected, their interconnections and their integration in a common remote control scheme. We also provide considerations and figures on the material and labour costs of the installation and management of the system. © 2015, Springer International Publishing Switzerland.

This paper takes a look at the conceptual foundations of Petri's net theory, including the crucial contribution by Anatol Holt to its development. We focus on several aspects which, although neglected in the mainstream of the literature on Petri nets, still bear, in our opinion, a value, both theoretically and in applications. Specifically, we deal with the notion of "formal pragmatics", and with the role of computers as a medium for organized communication, which should, in Petri's view, be paired with a general theory of information flow. A section will be devoted to the relations between Petri's theory and the formal apparatus of physics, a topic to which Petri gave special importance.
