  • 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 ...

  • Altitudinal patterns of maximum plant height on the Tibetan Plateau

    Abstract Aims Several studies have shown that plant height changes along environmental gradients. However, altitudinal patterns of plant height across species are still unclear, especially in regions sensitive to climate change. As canopy height decreases dramatically near the tree line in alpine areas, we hypothesize that plant height across all species also decreases with ...

  • Stemflow and its controlling factors in the subshrub Artemisia ordosica during two contrasting growth stages in the Mu Us sandy land of northern China

    The yield of stemflow from vegetation is mostly affected by rainfall and canopy structure, but few past studies have paid attention to the dynamics of canopy structure during the growth season. Artemisia ordosica is a typical subshrub, very different from trees and shrubs. Assessing the influence of canopy structure and rainfall on stemflow yield in A. ordosica during the ...

  • 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 ...

  • LIVE FROM THE NCRS: Yet Another Busy Day at the NCRS

    So yesterday (Wednesday Jul 22, 2015) was another busy day to take advantage of the nice weather.  Like moving the wheat harvest operation over to Farm 7. ...

  • 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 ...

  • The extrapolation of the leaf area-based transpiration of two xerophytic shrubs in a revegetated desert area in the Tengger Desert, China

    Plant transpiration plays a key role in sand-binding zones, but obtaining accurate estimates at an integrated leaf-individual-canopy scale is difficult. In this study, transpiration rates of two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were investigated during the growing season (April–October) from 2008 to 2012 in the Tengger Desert, a ...

  • 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 ...

  • Development and integration of a subgrid urban surface scheme in a limited area model

    The sub-grid model, sub-grid town energy budget (STEB), is developed in order to reproduce the surface energy budget over large urban areas. The STEB evaluates the energy budget of each building belonging to a built area by employing an accurate description of the canyon geometry. The STEB is coupled with the limited area model RAMS to simulate the urban heat island over the city of Rome, Italy. ...

  • 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. ...
