  • Managing slug pressure during harvest

    Growers should be mindful that slugs can thrive when there is no leaf canopy to protect the crop. This, combined with heavy rainfall and reports of increased slug populations this year, mean that good slug control at harvest is paramount. Top tips for slug control during harvest: Attention to detail During harvest focus on your attention ...

  • Electrically driven pumps with a canopy

    Clients regularly ask us for advice when planning their purchases. A common question concerns the electric pump sets: What is the advantage of an electric pump with a canopy compared to an open frame version? Whether it’s a mobile unit or a permanent installation used in the open air, electric pump sets with a closed canopy are growing in popularity every year. ...

  • Rainfall partitioning characteristics of three typical sand-fixing shrubs in Horqin Sand Land, north-eastern China

    Rainfall partitioning by vegetation affects water balance and utilization by plants. Caragana microphylla, Hedysarum fruticosum, and Salix gordejevii are three typical, morphologically different sand-fixing shrubs in Horqin Sand Land. However, few studies have compared rainfall partitioning by these shrubs. We examined rainfall partitioning differences among ...

  • When planting trees does more harm than good

    Note to anyone who thinks planting trees is the bees’ knees: Grasslands are important, too. With forests disappearing at record rates and the carbon sequestration and other benefits of vegetation getting increasing visibility, tree-planting has become almost an iconic “environmentally friendly” activity. But in some cases it could do more harm than good, according to Iowa State ...

  • Extreme Makeover: Photosynthesis Edition

    Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

  • Observations and snow model simulations of winter energy balance terms within and between different coniferous forests in southern boreal Finland

    Variation of canopy properties between different forest types is seldom taken into account in hydrological and climate models, and consideration of variation inside a forest is normally omitted. In this work, three data sets on near surface energy balance terms (incoming shortwave and longwave radiation; air and snow–soil interface temperatures) were collected in the southern boreal coniferous ...

  • Above the Big Top: CST and Bell County, Texas Put on a Blockbuster of a Show

    Even when the lead actor gets sick, the show must go on. Not only is that true in show business, but it’s also true with big entertainment venues. Keeping the lights on and the seats filled during an extended period of repairs is a testament to collaboration and intelligent design, and that’s the spirit behind a successful partnership between CST Covers and Bell County, Texas. The ...

  • First attempt to measure rainfall canopy interception loss, throughfall, and stemflow in Juglans regia Linn and Cup. Sempervirens L. Var. fastigiata in the north of Iran

    Each individual tree significantly alters the growth of surrounding vegetation by partitioning of rainfall and nutrients to the rooting zone. The Iranian Hyrcanian forests are among one of the most fragile ecosystems of the country owing to large industrial activities for logging and extensive urbanisation. These may accelerate disturbing of this unique type of forest. Of concern currently is an ...

  • The effects of conversion of tropical rainforest to rubber plantation on splash erosion in Xishuangbanna, SW China

    The Xishuangbanna (SW China) landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations. This study characterized the influence of conversion of tropical rainforest to rubber plantation on potential splash erosion rate and actual splash erosion rate. The average potential splash erosion rate was 2.1 times higher in the ...

  • Looking for a solid investment? How about conservation?

    Between 2009 and 2013, impact investors poured close to $23 billion into conservation projects such as water quantity and quality conservation, sustainable agriculture, and habitat conservation around the world. That’s according to a report, Investing in Conservation: A landscape assessment of an emerging ...

  • The effects of Picea schrenkiana forest litter on snow surface albedo

    In this paper, we analyze the characteristics of the snow albedo of different underlying surfaces based on measurements of shortwave radiation and observations of forest litter on snow surfaces, both in an open, unforested environment and in areas with differing forest canopy openness. The fractional litter coverage was obtained through the binarization of digital photos of forest litter ...

  • Evaluation of the AquaCrop model for simulating yield response of winter wheat to water on the southern Loess Plateau of China

    The objective of this study was to evaluate the performance of the FAO-AquaCrop model in winter wheat in the southern Loess Plateau of China. Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root mean ...

  • The impact of beetle-induced conifer death on stand-scale canopy snow interception

    Bark beetles have killed more than 100,000 km2 of pine forest in western North America, causing trees to lose the majority of their canopy material and potentially leading to enhanced subcanopy snow accumulation. Over a 45-day period, we tested this hypothesis by measuring daily snow accumulation in three living and two dead lodgepole pine stands and in three adjacent clearings. The largest ...

  • Threshold velocity of pollination in urban area of the city of Brno

    Wind velocity directly influences pollen release rate from mother plants and subsequently, the transport of pollen grains. The threshold velocity of pollination is defined as the lowest wind velocity with evidence of pollen concentration above the threshold pollen concentration. Only a limited number of published papers deal with the relationship between wind velocity and pollen concentration. ...

  • LAGFLUM, a stationary 3D Lagrangian stochastic numerical micromixing model for concentration fluctuations: validation in canopy turbulence, on the MUST wind tunnel experiment

    A stationary three–dimensional Lagrangian stochastic numerical model, LAGrangian FLUctuation Model (LAGFLUM), was developed by coupling a macromixing with a micromixing scheme, to determine the mean and the variance of concentration for a passive scalar in 3D turbulent flows. The model was tested by comparison with the (MUST) Mock Urban Setting Test wind tunnel experiment, where the dispersion of ...

  • Measurement of Canopy/Vegetation Reflectance with the UniSpec-DC

    A good method for sampling reflectance of vegetation canopies is to connect a flexible, lightweight fiber optic cable (also referred to as “Foreoptic”) of a desired length to the detector. This requires a fiber optic with an SMA type connector at one end (to thread on to the detector) and a foreoptic with a defined field-of-view (FOV) at the other end (to limit the field of view to a ...

  • Evaluating the models of stomatal conductance response to humidity in a tropical rain forest of Xishuangbanna, southwest China

    The ecosystem-level fluxes of water vapour and carbon dioxide were measured from 2003 to 2006 at a tropical rain forest in Xishuangbanna, southwest China, using the eddy covariance (EC) technique. These flux measurements allowed the canopy-level evaluation of stomatal conductance (g) response to humidity models. The results showed that both the BWB model and the Leuning model discussed here ...
