  • 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 ...

  • 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 ...

  • Differential effects of low humidity levels on butterhead quality indices related to external, middle and internal lettuce sections

    Leaf water status evolution during greenhouse butterhead lettuce storage under adverse humidity conditions was evaluated. The relationships between water status and the chlorophyll content and overall visual quality (OVQ) were analysed. Parameters were evaluated in external, middle and internal sections of the lettuce heads. Indices showed different behaviour in different sections. There was a ...

  • Soil seed bank composition in pastures of diverse mixtures of temperate forages

    Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

  • 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 ...

  • 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 ...

  • 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 ...

    Kids love food, but it's not always the tasty treats that are good for them or the earth. Fatty, sugary, salty and processed foods generally have more of an environmental impact than eats of the fresh, locally produced variety. It is therefore important to teach them what is healthy to eat, and how and where their food comes from. This will help them to understand the impact of the food they eat, ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...
