  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • The ratio of transpiration to evapotranspiration in a rainfed maize field on the Loess Plateau of China

    Maize (Zea mays L.) is a major crop on the Loess Plateau, and calculating the ratio of transpiration to evapotranspiration (T/ET) of maize is important for estimating field water balance. In this study, the sap flow method was adopted to measure transpiration (T) characteristics of maize. In order to calibrate the sap flow gauge, the sap flow rate was compared to the leaf T determined by the ...

  • Effects of two fungicide formulations on microbial and macroinvertebrate leaf decomposition under laboratory conditions

    Aquatic fungi contribute significantly to the decomposition of leaves in streams, a key ecosystem service. Little is known, however, about the effects of fungicides on aquatic fungi and macroinvertebrates involved with leaf decomposition. Red maple (Acer rubrum) leaves were conditioned in a stream to acquire microbes (bacteria and fungi) or leached in tap water (unconditioned) to simulate ...

  • Accumulation of 2,4‐dinitroanisole in the earthworm Eisenia fetida from chemically spiked and aged natural soils

    An initiative within the U.S. military is targeting the replacement of traditional munitions constituents with insensitive munitions (IM) to reduce risk of accidental detonation. The bioavailability and bioaccumulative potential of the IM compound 2,4‐dinitroanisole (DNAN) to Eisenia fetida was assessed in soils with different geochemical characteristics. Prior to exposure, soils were ...

  • Effects of ivermectin application on the diversity and function of dung and soil fauna: Regulatory and scientific background information

    The application of veterinary medical products (VMPs) to livestock can impact soil organisms in manure‐amended fields or adversely affect organisms that colonize dung pats of treated animals, and potentially retard the degradation of dung on pastures. For this reason, the authorization process for VMPs in the European Union includes a requirement for higher‐tier tests when adverse effects on ...

  • A study on crown interception with four dominant tree species: a direct measurement

    An experiment was conducted to concentrate on the rainfall interception process of individual trees for four common species in Beijing, China, which included needle species (Platycladus orientalis and Pinus tabulaeformis) and broadleaf species (Quercus variabilis and Acer truncatum). Two types of interception storages, the maximum ...

  • Water-retention potential of Europe`s forests

    A European overview to support natural water-retention measures One third of European territory is covered by forests (210 million ha). Approximately 296 million European inhabitants live in — or close to — forests. European forests are also closely connected to much of the hydrological network, and serve large groundwater bodies and many river sources. Forests provide more ...

  • 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 ...

  • “Soil Health” And Compost

    In my quest to better understand how compost improves the chemical, physical and biological attributes of soil, I came across a training course created by the Rodale Institute, with support from the Northeast Region Sustainable Agriculture Research and Education (SARE) Program called “An Introduction to Soil Health.” The course emphasized that if we can improve the overall quality of ...

  • Leaf area index as a function of precipitation within a hydrological model

    The Leaf Area Index (LAI) was derived from the Normalised Difference Vegetation Index (NDVI) obtained from Advanced Very High Resolution Radiometer (AVHRR) data for the years 1982–2004. The NDVI-derived LAI showed a very good agreement (correlation coefficient r up to 0.96) with MODIS LAI. To address the relation between precipitation and LAI, linear correlation analysis between ...

  • Benefits of minimum tillage case study

    In Hungary, the MARGINS project is being conducted near Lake Balaton - the largest lake in Central Europe. The lake is renowned for its beauty and wildlife. Its surrounding hilly landscape is covered with rich brown forest soil. This landscape is, however, prone to soil erosion -in particular, rills develop when soil is weakened by excessive tillage and exposed to intense rainstorms. If not ...

  • Effect of metal-ion doping on the characteristics and photocatalytic activity of TiO2 nanotubes for the removal of toluene from water

    Toluene is an extensively used reagent that could cause water pollution and endanger human health. In this work, an O3/UV/ion-doped TiO2 nanotubes process was investigated to obtain the optimum TiO2 nanotubes for effective toluene decomposition. Photocatalytic activity is found to be influenced by the doped-ion type by affecting the ionic radius, valence state, and ...

  • Calculations used in porometry application notes

    A porometer measures gas flow as function of an applied pressure. Typical curves for the wet and dry curve for a filter or membrane are shown in figure 1 below. The wet curve is measured to determine the pore sizes, the dry curve is needed for the calculation of both the mean flow pore size, smallest pores and the gas permeability. As one can read in the application note about the determination ...


  • Coffee cherry husk - a potential feed stock for alcohol production
