  • Innovative strategies for physical weed control on processing tomato in the Serchio Valley (Central Italy).
    2008
    Co-Authors: Andrea Peruzzi, Michele Raffaelli, M Ginanni, L Lulli, Christian Frasconi, Marco Fontanelli
    Abstract:

    An “on-farm” open field research on processing tomato weed control was carried out during 2006 in a conventional farm in the Serchio Valley (Pisa, Central Italy). The aim of the experiment was to test Innovative strategies and operative machines for non-chemical (physical) weed control. The Innovative Strategy was compared with the farm traditional technique. The Innovative Strategy consisted in the application of the stale-seedbed technique (by means of a rolling harrow and a flaming machine in the pre-transplanting phase) and precision hoeing interventions in post-transplanting phase (with an Innovative machine equipped with rigid elements, for inter-row weed control, and elastic tines for selective intra-row weed control). Traditional technique consisted in two chemical pre-transplanting interventions and two post-transplanting rotary hoe treatments. Innovative operative machines performances, weed density during the crop cycle, dry weed biomass at harvest and crop fresh yield were recorded. The Innovative Strategy allowed to reach significantly higher yield values (+18%), a good weed control and a relevant increase of gross marketable production with respect to traditional Strategy (+4500 € ha-1 as net value of weed management costs). The experiment is still on-going and it will finish in 2008.

  • Innovative Operative Machines for Physical Weed Control on Processing Tomato in the Serchio Valley (Central Italy)
    2008

    Abstract:

    Processing tomato is the first Italian vegetable crop for harvested area (about 94000 ha) weed control represent one of the most serious problem for tomato producers. A two year “on-farm” open field research on processing tomato weed control was carried out in 2006 and 2007 in a conventional farm in the Serchio Valley (Pisa, Central Italy). The aim of the experiment was to test Innovative strategies and operative machines for non-chemical (physical) weed control in order to reduce agrochemical input and improve crop quality. The Innovative Strategy was compared with the farm traditional technique. The Innovative Strategy consisted in the application of the stale-seedbed technique (by means of a rolling harrow and a flaming machine in pre-transplanting) and precision hoeing interventions in posttransplanting (with an Innovative machine equipped with rigid elements, for inter-row weed control, and elastic tines for selective intra-row weed control). Traditional technique consisted in two chemical pre-transplanting interventions and two post-transplanting PTO powered rotary hoe treatments. Innovative operative machines performances, weed density during the crop cycle, dry weed biomass at harvest and crop fresh yield were recorded. The Innovative Strategy allowed reaching significantly higher yield values (from 15 to 20%), a good weed control and a relevant increase of gross marketable production with respect to conventional management (from 400 up to 700 € ha -1 of increase as net value of weed management costs) The experiment is still on-going and it will finish in 2008.

  • Review: Oxidation of lignin using ionic liquids - an Innovative Strategy to produce renewable chemicals
    ACS Sustainable Chemistry & Engineering, 2014
    Co-Authors: Gregory Chatel, Robin Rogers
    Abstract:

    Lignin, one of the three subcomponents of lignocellulosic biomass (along with cellulose and hemicellulose), represents more than 20% of the total mass of the Earth's biosphere. However, essentially due to its complex structure, this renewable polymer derived from biomass is mainly burned as a source of energy in the pulp and paper industry. Today, the valorization of lignin into the production of chemical feedstocks represents a real challenge in terms of both sustainability and environmental protection. This review first briefly outlines the main points of this challenge and compares the different methods investigated by chemists over the past several decades, pointing out the major difficulties met. Next, the review highlights the recent use of ionic liquids (ILs) as solvents that have provided some new opportunities to efficiently convert lignin and lignin model compounds into value-added aromatic chemicals. Particular focus is given to these new strategics in terms of selectivity, separation and the unique compounds obtained for the oxidation of lignin using ILs. Finally, an assessment of the challenges that must be resolved in order for ILs to become an eco-friendly way of producing chemicals from biomass, including lignin, is proposed.
