Improving soil conservation and resource use in organic cropping systems for vegetable production
Agro-ecological Service Crops (ASC) are introduced in the agro-ecosystems to provide or enhance ecological services, thus promoting the whole soil-plant system equilibrium. ASC introduction and proper management have impact on soil quality and fertility and soil nutrients losses. They also contribute to increase soil C sink potential, to mitigate GHG emissions and influence weeds, diseases and pests occurrence.
To avoid competition with the subsequent cash crops, the growth of the interposed ASC is terminated in advance of the cash crop planting. The traditional, most widespread, technique used to terminate the ASC is incorporation as green manure into the soil by tillage. Since tillage is an energy and labour consuming and soil disturbing operation, the use of no/reduced tillage techniques, as the rolling crimping technology that terminates by flattening the ASC, has received increasing interest. The main challenge of the project will be to test the hypothesis that, compared with the incorporation of ASC into the soil as green manure, the use of the roller crimper reduces nutrient losses from the soil/plant system and GHG soil emission.

Expected societal benefits of the project
The project will have a relevant impact since organic vegetable growers will benefit from the project outcome as a system to mitigate the negative effects of pests and weeds, to reduce the nutrients losses from soils, crop nutrient use efficiency and consequently the dependence on farm import of animal manure and the fossil fuel energy consumption. Consequently, the vegetable farmers will be able to produce quality produce with lower use of external inputs, thus improving farm profitability.
Rural communities will benefit from the project outcome in terms of improved environmental profile of organic vegetable farms and this will reduce negative environmental impacts on soil, water and atmosphere.
Consumers will benefit from the project as they will have the chance to access to vegetable produces obtained in low environmental impact production systems. Policy makers could use the project outcomes in setting or improving standards for organic vegetable production for EU Regulations and for rural development plans and premium schemes.
Expected outcomes, results and impact
The main expected result is the optimisation and the spreading of novel ASC management strategies aimed to improve soil quality and to enhance resources use in organically managed systems for vegetable production.
During the next three years, SOILVEG research activities will aim at verifying the hypothesis that the use of the roller crimping technology for ASC termination is able to:
Expected long-term impact
The smart designing of cropping system and the use of ASC have been included in the list of the most promising techniques to improve N use efficiency and reduce the risk of nitrate leaching. It is expected that the results obtained in this project in the area of the cropping system smart designing and Agro-ecological Service Crops exploitation will contribute to meet the increasing demand of innovation and to give to the European OFF sector a leading role in a global perspective.
