Abstract

Soil solarization relies on solar radiation being converted to heat for the killing of soilborne pathogens. On one hand, this technique can be considered as an environmentally-friendly way to manage soil borne pests, as an alternative of methyl bromide phased-out in 2005, than using chemicals. On the other hand, high employment of traditional plastic sheets in agriculture causes the production of enormous quantities of waste, whose inappropriate management might have negative effects on the environment. In order to determine a reduction of the charge of plastic waste and to facilitate the waste disposal, one of the most interesting approaches, from an environmental point of view, lies in the location of innovatory plastic films such as co-extruded ultrathin films, which are able to reduce the plastic quantity to be managed, and biodegradable larninates, which after a first usage, will spontaneously start up a degradation process that avoids their collection and their con sequent disposal. Beside the ecological proprieties of these innovative films, it is necessary to study their technical and agronomical behavior in order to determine their efficiency and the possibility to be used in pIace of the traditional plastic films. This paper represents a review of the researches carrier out by the Technical Economics Department of the University of Basilicata (Italy) in the last years (1999, 2000, 2002 and 2003) on the technical performances of some innovative plastic films used for soil solarization.
