  • Evaluation of greenhouse gas emissions and design of mitigation options: a whole farm approach based on farm management data and mechanistic models

    Agricultural activities are important sources of nitrous oxide (N22O), methane (CH4) and carbon dioxide (CO2). They contribute approximately 10% of the total emitted greenhouse gases (GhG) in the European Union. We search for evaluating GhG emissions at the farm level and designing mitigation options. As emissions occur at many stages within the farm operation, it is crucial to ...

  • Motor transport, greenhouse gases and economic instruments

    Motorised transport is the generator of several forms of negative externality including the uncompensated emissions of greenhouse (global warming) gases. This paper looks at some of the underlying economic issues pertaining to policy-making designed to limit the extent of these externalities. It sets out the basic nature of the problem and outlines our knowledge of the link between the physical ...

  • Separating the wheat from the chaff: Regulating greenhouse gases in a climate of uncertainty

    This article discusses the difficulty of regulating greenhouse gas emissions in the face of uncertainty, particularly with respect to the level of reductions needed in the post-2012 era to avoid dangerous climate change. There are also a number of regulatory options available, including carbon taxes, emissions trading, regulations and standards, and fiscal measures. Yet emissions trading has ...

  • Fertilizer application timing influences greenhouse gas fluxes over a growing season

    Microbial production and consumption of greenhouse gases (GHG) is influenced by temperature and nutrients, especially during the first few weeks after agricultural fertilization. The effect of fertilization on GHG fluxes should occur during and shortly after application, yet data indicating how application timing affects both GHG fluxes and crop yields during a growing season are lacking. We ...

  • Comparison of date-palm wastes and perlite as culture substrates on growing indices in greenhouse cucumber

    Abstract Different substrates have several materials which could have direct and/or indirect effects on plant growth and development. Therefore selecting the best substrate between the ...

  • Performance evaluation of condensation–irrigation solar system under arid climate conditions

    Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid climate ...

  • 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 ...

  • 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 ...

  • President Obama signs executive order reducing federal GHG emissions

    On March 19, 2015, the White House published an Executive Order signed by President Obama that would further a preference for U.S. Department of Agriculture (USDA) BioPreferred products. Planning for Federal Sustainability in the Next ...

  • Case study - Pelton Reforestation Ltd., Maple Ridge, British Columbia, Canada

    “In 1986 our company used Sidel Systems to design and install a complete hot water heating system in our 135,000 sq./ft. greenhouse. The system was comprised of 51mm heating loops, headers with computer controlled mixing valves, and a 500 HP gas fires Cleaver Brooks Boiler outfitted with a matching flue gas condenser unit. Over the next 3 years we added additional greenhouse space and the ...

  • Nutrient acquisition and yield response of Barley exposed to salt stress under different levels of potassium nutrition

    Abstract: A greenhouse experiment was carried out in 2002 at Jordan University of Science and Technology, Agricultural Experiment Station to examine the effect of potassium fertilization on the response of barley (Hordeum vullgare L.) to different soil salinity levels. Five levels of potassium (0, 0.2, 0.4, 0.6, and 0.8 g K per pot as KCl) and two salt levels (0.75 and 13 ds/m) were ...

  • Case study - Finally - a fan for the 21st century

    Travis Luther, owner of Forcefield, designs and builds Advanced Greenhouse Climate Solutions in southern Oregon, USA. He bought MagFans for his greenhouses and he is impressed with the powerful, efficient and quiet fan. - Being in a hot dry climate, we rely on evaporative cooling to keep the temperature from climbing to detrimental levels in the summer. This requires massive air flow to ...

  • Growth and transpiration of tomato seedlings grown in hazelnut husk compost under water-deficit stress

    This study was carried out to determine effects of composted hazelnut husk (CHH) on tomato seedlings grown under water stress conditions. Seven media were prepared using CHH mixed, in different ratios, with native peat and perlite. The following mixtures were used: 100%CHH, 100%peat, 75%CHH+25%peat, 50%CHH+50%peat, 25%CHH+75%peat, 25%CHH+50%peat+25%perlite and 50%CHH+25%peat+25%perlite. The ...

  • Assessing agroforestry`s advantages

    Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

  • Climate cooperation as development policy: the case Of Costa Rica

    Project-based climate cooperation between industrial and developing countries was first proposed in the early l990s, then under the name of joint implementation (JI). Once in place, this cooperation could lead to a high amount of additional financial flows to developing countries. Nevertheless, many NGOs and developing country representatives were in the beginning very sceptical about JI and ...
