  • Produce Grower, August 2017 issue

    There may be no such thing as a perfect tomato, but due to research by Amy Bowen and Dave Liscombe at the Vineland Research and Innovation Centre, growers are one step closer to producing great ones. In 2012, the Ontario Greenhouse Vegetable Growers put out a list of research priorities, and one of those priorities was to improve or differentiate flavor in tomatoes. The focus was on tomatoes on ...

  • Blending and Bagging at Sungro Production Facility

    What’s In The Bag? A recent visit by FibreDust to the Sun Gro Horticulture blending facility, located just outside of Orlando, Florida, gave a glimpse into the business of soilless media and blending. The facility had a massive mixing and bagging line with 14 huge hoppers that added essential ingredients to soilless blends. Numerous tidy bunkers of various additives were scattered ...

  • Valuation of nitrogen retention as an ecosystem service on a catchment scale

    An ecosystem service approach was used to study the water purification service exemplified by impacts of land management scenarios. Nitrogen retention was calculated in two agricultural catchments by the dynamic Integrated Nutrients in Catchments (INCA)-N model. The monetary valuation was based on purification efficiency of artificial wetlands. The set of scenarios were based on existing ...

  • Soil genotoxicity induced by successive applications of chlorothalonil under greenhouse conditions

    Greenhouse production of vegetables has been developed rapidly in China. High temperature and humidity inside the greenhouse make this environment more suitable for fast reproduction of fungal diseases. Fungicides are among intensively used chemicals in the greenhouse to prevent crops from the invasive infection of phytopathogen, however, little is known about accumulation of fungicides in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Monitoring greenhouse gas emissions from hydroelectric reservoirs in northern Quebec, Canada

    Surface waters of natural freshwater bodies are capable of releasing far more carbon into the atmosphere than they absorb (Cole et al. 1994). Artificial reservoirs are also known to have environmental impacts which include greenhouse gas (GHG) emissions (Rosenberg et al. 1997, Fearnside et al. 2004, Tremblay et al. 2005). Therefore the inclusion of hydroelectric facilities as part of an overall ...

  • Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution

    Abstract  A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg−1) for iodide (I−) and iodate (IO3−) were used. Results showed that the biomass productions of spinach were not ...

  • Greenhouse concentration and sustainable horticulture in densely populated areas

    During the last two decades, the production value of the Belgian horticultural sector has increased substantially and represents almost a quarter of the total agricultural production value. Within the total production value of vegetables, greenhouse production represents almost half. Despite having so much importance, the greenhouse sector faces a lot of problems in relation to sustainability ...
