  • Native cover crops suppress exotic annuals and release native perennials in a greenhouse competition experiment

    In a greenhouse experiment, we examined the effectiveness of four native cover crops for controlling four exotic, invasive species and increasing success of four western North American grassland species. Planting the annual cover crops, annual ragweed (Ambrosia artemisiifolia) and common sunflower (Helianthus annuus), reduced the biomass of the exotic species cheatgrass (Bromus tectorum), ...

  • Fluorinated greenhouse gases 2011

    Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases typically have very long lifetimes in the atmosphere and high global warming potentials (GWPs). The European Union Regulation (EC) No 842/2006 on ...

  • Fluorinated greenhouse gases 2013

    Aggregated data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union. Background and policy The greenhouse gases (GHGs) covered by the UNFCCC Kyoto Protocol include three groups of fluorinated GHGs (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) ...

  • Methane flux in cropland and adjacent riparian buffers with different vegetation covers

    Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

  • Root penetration through sealing layers at mine deposit sites

    To prevent acid mine drainage arising from oxygen and water penetration of sulphide-rich mine tailings, the tailings are covered with layers of dry sealing material. Plant roots have a great ability to penetrate dense materials, and if the roots are able to penetrate the sealing layer of a tailings deposit, its oxygen-shielding properties could be reduced. The objective of this study was to ...

  • Bottom line on regional cap-and-trade programs

    Three regional greenhouse gas cap-and-trade programs are either in the planning stages or operational in North America. This brief discusses each of the programs. What is happening on the regional level and why is this significant? Twenty-three U.S. states and four Canadian provinces are actively participating in the design and implementation of three regional cap-and-trade programs to ...

  • Submission on additional CDM activities - 2012

    Currently, the only land-use, land-use change and forestry (LULUCF) activities that are eligible under the Clean Development Mechanism (CDM) are afforestation and reforestation (A/R), which allows for the generation of credits by net removal by sinks. This could include afforestation and reforestation of wet organic soils (peatlands), e.g. with swamp forest tree species. Conservation, ...

  • Case study - Fitmar, Mexico

    Coming from a long line of professional fisherman, the Fitmar family business made a switch from fishery to aquaculture. Seeing aquaculture as a more future proof way of supplying seafood to the local market, this was a very deliberate choice. In order to establish a professional and economically viable model, Fitmar decided to invest a lot of time and effort in optimized hatchery and nursery ...

  • The effect of amendment of vegetable waste compost used as substrate in soilless culture on yield and quality of melon crops

    One of the main environmental impacts of forced systems in horticulture — such as plastic covered and soilless culture — is the generation of organic plant residues and substrate waste. Many people are keen on research and development of ecologically friendly substrates. Thus, leaching experiments have been carried out with distilled water to determine whether compost — from horticultural ...

  • Pilot scale facility to determine gaseous emissions from livestock slurry during storage

    Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

  • Rough Brothers' Conservatories

    Founded in 1932, Rough Brothers’ original business focus was greenhouse maintenance and repair. But, things are far different today. Company growth has been steady in recent years as the breadth of Rough Brothers’ services and products has far exceeded what the original five ‘Rough’ brothers could have ever imagined. Today Rough Brothers and its sister companies cover the ...

  • Agroforestry Mitigates Climate Change

    Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the ...

  • Response of nitrogen uptake and partitioning to critical nitrogen supply in oat cultivars

    Nitrogen uptake and partitioning in oat (Avena sativa L.) are not well documented. A greenhouse study was conducted to determine the critical timing of N supply on the growth, N uptake, and partitioning. Plants grown in plastic pots were subjected to five N fertilization regimes: (i) control, N supply from seedling to physiological maturity (PM); (ii) N supply from seedling to flag leaf; (iii) N ...
