Evaluation of sustainability: results from long term experimental arable systems in Tuscany Organic Eprints
Migliorini, Paola; Vazzana, Concetta.
The research is aimed at implementing a methodology in order to estimate the sustainability of an agricultural system, through the use of Agro-ecological and Sustainability Indicators. The methodology is applied to three stockless, experimental agricultural systems, part of a long-term experiment (MOLTE) managed with diverse typologies (old organic, new organic vs conventional). The results derived from the three different management systems are estimated by considering crop rotation and efficiency in terms of energetic, macro-element (N, P, K) and organic matter flow. These are related to the landscape and biodiversity system, as well as the soil and the environmental system. The research shows that the agro-ecosystems managed with the organic agriculture...

Effects of green-manure and organic fertiliser on organic maize (Zea Mays L.) in south Tuscany Organic Eprints
Mazzoncini, Marco; Migliorini, Paola; Antichi, Daniele; Vazzana, Concetta.
Green-manure in Mediterranean stockless organic farms is a useful tool to improve nitrogen availability, reduce production cost and conserve soil fertility. A 2-year on farm research was carried out in Tuscany (Italy) to evaluate the effect of 3 different green manures (Hordeum v. + Avena s. mixture, Trifolium s. + Avena s. mixture, Vicia faba var. minor) and 2 levels of organic N fertilization (0 and 120 Kg N ha-1) on maize in 2004 and 2005. Green manures were ploughed into the soil in April 2004 and organic fertiliser was applied before sowing; neither green manure nor fertilizers were applied in 2005 to evaluate the residual effect of the treatments. The effect of the distribution of organic fertilizer was not efficient in comparison to green-manure....
