  • 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 ...

  • Scalewatcher Banishes Limescale In Gardens And Greenhouses

    In hard water areas, automated watering systems, sprinkler irrigation systems and greenhouse-misting systems clog with limescale, plant leaves develop white scale deposits and over-spray causes limescale build-up on greenhouse windows. Scalewatcher North America, manufacturers of the original, patented and award-winning computerized electronic water-conditioner, Scalewatcher®, has a range of ...

  • Svalbard: 25 procent increase in greenhouse gases

    The concentration of the greenhouse gases hydrofluoro-carbons (HFC) in the atmosphere above Svalbard have increased with 25% in 2003. This is described in a new research report the Norwegian Institute for Air Research (NILU) has compiled for the Norwegian Pollution Control Authority (SFT). The measurements shows that most of the greenhouse gases and other ozone reducing substances in the ...

  • Greenhouse care economics: a solution to the capitalist's dilemma

    This paper argues that the challenges like poverty, inequality, debt crisis, recession or environmental damage faced by our current world are created because of the individuals who hold the control of our capitalists institutions are in dilemma similar to prisoner's dilemma. It tells that a capitalist's growth compulsion is driven by his competitors' profit maximisation goal. Whatever the crisis, ...

  • The Latest in Whitefly Control

    Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

  • Matrix-based fertilizers reduce nutrient and bacterial leaching after manure application in a greenhouse column study

    Received for publication November 7, 2008. We tested the efficacy of matrix-based fertilizers (MBFs) to reduce Escherichia coli and Enterococcus spp., NH4, NO3, dissolved reactive phosphorus (DRP), and total phosphorus (TP) in leachate and soil after dairy manure application in greenhouse column studies. The MBFs are composed of inorganic N and P in compounds that are relatively loosely bound ...

  • Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows

    Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

    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 ...

  • The use of treated wastewater and fertigation in greenhouse pepper crop as affecting growth and fruit quality

    The performance and suitability of tertiary treated wastewater (TW) and/or fertigation (F) in pepper plants were studied over a 4-month period in greenhouse conditions. Four treatments were used consisting of (1) water, (2) water + F, (3) TW, and (4) TW + F. The F and/or TW application increased plant height and plant biomass compared with the control plants (irrigated with water) ...
