  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...

  • Have Your Steak and Eat It, Too

    In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ways ...

  • Chicago Council lists three-decade changes in greenhouse gases and average temperature

    In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

  • Influence of initial pesticide concentrations in water on chlorpyrifos toxicity and removal by Iris pseudacorus

    For understanding the influence of initial concentrations of pesticides in the water body on removal efficiency of the contaminant by aquatic plants, one hydroponics experiment was used to investigate the influence of initial concentration (1–16 mg L−1) on toxicity and chlorpyrifos removal potential of Iris pseudacorus for 20 days under greenhouse conditions. An ...

  • Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm

    Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

  • 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 ...

  • Greenhouse packs a power punch

    Closed loop system utilizes gasification, algae ponds and anaerobic digestion to convert wood waste to a variety of products, including biofuel, biogas and a soil amendment. MICHAEL Smith is supervising the first commercial-scale Green Power House at the F.H. Stoltze Land and Lumber Co. near Columbia Falls, Montana. Smith, a physicist, has designed a system to take waste products and turn them ...

  • Strategies to mitigate diffuse phosphorus pollution during rewetting of fen peat soils

    The cultivation of fen peat soils (Eutric Histosols) for agricultural purposes, started in Europe about 250 years ago, resulting in decreased soil fertility, increased oxidation of peat and corresponding greenhouse gas fluxes to the atmosphere, nutrient transfer to aquatic ecosystems and losses in total area of the former native wetlands. To prevent these negative environmental effects set-aside ...

  • Arsenic hyperaccumulation by Pteris vittata and Pityrogramma calomelanos: a comparative study of uptake efficiency in arsenic-treated soils and waters

    This work comprised of the comparative study of arsenic (As) uptake efficiency by Pteris vittata and Pityrogramma calomelanos grown in (i) As amended soils (0–600 ppm) and (ii) As tainted water (40 ppb) using a new compact continuous flow phytofiltration system in a tropical greenhouse. The As hyperaccumulation efficiency was dependent on the growth medium for the two fern ...

  • Pesticide runoff from greenhouse production

    A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

  • Impact on Australia and Pacific Islands of climate change due to enhanced greenhouse effect

    Climate in any particular region of the Earth can change due to many factors. Potentially one of the most significant is changes in atmospheric concentration due to increased emission of greenhouse gases. This could lead to significant changes in temperature and precipitation on a regional basis with significant effects on regional economies and societies. Potential impacts on Australia are ...

  • Gas exchange and transpiration ratio in Sorghum

    Decreased water availability and increased food demand worldwide require development of more water-efficient crops. This study was conducted to examine preflower transpiration ratio (CO2 assimilation rate [A]/transpiration rate [E], A:E) in four inbred sorghum [Sorghum bicolor (L.) Moench] lines and 12 of their F1 hybrids in terms of phenotypic and genetic variation, inheritance (i.e., additive ...
