Caractérisation et évaluation de pratiques agroécologiques en systèmes maraîchers biologiques diversifiés sur petites surfaces : expérimentations paysannes dans les Alpes-Maritimes

Abstract : MiMaBio project "Small-scale diversified organic market gardening systems in the PACA region" aims at assessing agroecological practices to develop this kind of system. For the third year of the project, 7 peasant experiments have been set up, of which 3 are explained. The effect of milk kefir sprayings on tomato plants Solanum lycopersicum, the impact of double mulching on squash Cucurbita, and the sustainability comparison of 2 trellis made from cotton or plastic have been assessed. Several measurements have been done such as crop growth, microbial activity, pest and disease impact and severity, soil structure, nitrate content in soil, soil temperature and water availability, among others. Data obtained from the field have been statistically analyzed thanks to Tukey or Dunn pairwise comparison tests, trends were identified when tests weren’t significant. Some results from these experimented practices led us to show trends in the increase of microbial activity with milk kefir, buffering effect on soil temperature of double mulching, high environmental impact of cotton trellis. Moreover, the peasant experiment approach associated to environmental constraints highlight the advantages and drawbacks of this method to assess agroecological practices.
