A research was carried out in order to test innovative biodegradable materials for the protected cultivation of the strawberry in Southern Italy. A field test was carried out in order to evaluate the agronomic performances of the biodegradable materials in comparison with non biodegradable LDPE materials. Different kinds of biodegradable black films were used for the soil mulching and transparent biodegradable films for the covering of the low tunnels. Climatic data of the site, air temperature and relative humidity inside the low tunnels and soil temperature under the mulching films were gathered during the test. Besides laboratory radiometric tests were executed on the films in order to evaluate parameters such as the transmissivity in different wavelength ranges. The biodegradable materials showed a high capacity to induce the greenhouse effect due to their very low transmissivity in the long wave infrared range. The yield obtained using biodegradable materials was on average 12% higher then the one obtained with traditional films. Concerning the earliness, at the first day of the harvest, the yield obtained with biodegradable materials was 70% higher in comparison with the case of LDPE films.

Abstract

A research was carried out in order to test innovative biodegradable materials for the protected cultivation of the strawberry in Southern Italy. A field test was carried out in order to evaluate the agronomic performances of the biodegradable materials in comparison with non biodegradable LDPE materials. Different kinds of biodegradable black films were used for the soil mulching and transparent biodegradable films for the covering of the low tunnels. Climatic data of the site, air temperature and relative humidity inside the low tunnels and soil temperature under the mulching films were gathered during the test. Besides laboratory radiometric tests were executed on the films in order to evaluate parameters such as the transmissivity in different wavelength ranges. The biodegradable materials showed a high capacity to induce the greenhouse effect due to their very low transmissivity in the long wave infrared range. The yield obtained using biodegradable materials was on average 12% higher then the one obtained with traditional films. Concerning the earliness, at the first day of the harvest, the yield obtained with biodegradable materials was 70% higher in comparison with the case of LDPE films. The research showed that the biodegradable materials could be a sustainable alternative to the plastic films based on fossil raw materials
