Reti per l’agricoltura: caratteristiche costruttive e tipologiche

Permeable covers are extensively used in certain types of cultivation such as fruit-tree farming, for bird and insect protection as well as anti-hail and anti-frost shields or windbreaks. Moreover, nets are used as insect protecting screens along greenhouse ventilation openings, shading screens above greenhouse roofs, etc. In these applications, plastic nets are considered as an environmental and human health friendly alternative to pesticides, which also reduce the risk of damage of the production under adverse climatic conditions. In this respect, agricultural nets support the production of higher quality, lower input products using lower levels of agrochemicals and, in some cases, reducing or eliminating the need for energy consumption. However, their design and use is more or less empirical and the design and construction of the supporting structures are grossly empirically modified greenhouse frames or farmers made constructions, which usually pay little respect to the environment. In this study the main characteristics of agricultural nets, their use, the supporting structures and standard adopted are described.
