  • Use of online nutrient monitoring for automatic aeration and nitrate recycle pump control

    The Northside Wastewater Treatment Plant (WWTP) in Kinston, NC was expanded and upgraded in 2006 for biological nutrient removal (BNR) to meet limits of 3 mg/L total nitrogen (TN) and 1 mg/L total phosphorus (TP). In addition to the traditional approach of controlling the blowers based on dissolved oxygen (DO) readings, the City decided to implement an aeration basin blower control system using ...

  • Zonejection: Conservation tillage manure nutrient delivery system

    Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

  • Seasonal nutrient uptake of plant biomass in a constructed wetland treating piggery wastewater effluent

    The surface-flow constructed wetland (CW) located in Nonsan City, South Korea, and constructed as the final stage of a piggery wastewater treatment plant that aims to treat high nutrient content effluent during dry days and stormwater runoff during wet days was monitored from October 2008 to November 2011. This research investigated the seasonal nutrient uptake of plant biomass in the CW and ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Phosphate detection in water - a potential amperometric approach

    Excess phosphorus causes eutrophication (excess of nutrient promoting a proliferation of plants, (especially algae) inecosystems. Consequently, the monitoring of phosphate in waste, drinking and natural water is of major importance.There is a strong interest in a method alternative to the standard molybdate colorimetric method, which is not well suited to continuous monitoring under field ...

  • Fate of Agrochemicals in Terrestrial Ecosystems; An Integrated Modelling Framework: Application to The Loire (Fr)

    A fast growing economy and a more demanding population in Europe is leading to increasing socio-economic pressures, and large-scale land use and landscape changes are taking place. An increasing pressure is put on water resources and conflicts are arising for water distribution among different stakeholders, and degradation of water quality is exacerbating the problem. ...


  • Irrigation of eucalyptus plantation using treated bleached kraft pulp mill effluent

    The use of treated pulp mill effluent on eucalyptus plantation appears to be an attractive option for plant nutrition and water supply. It also constitutes a supplementary treatment process and a final disposal option for the mill effluent. This study aimed at the investigation and evaluation of the effects of bleached kraft pulp mill treated effluent on three typical Brazilian soils used for ...

  • An Atlas of pan-European data for investigating the fate of agrochemicals in terrestrial ecosystems

    In 2000, with the enforcement of the Water Framework Directive (WFD) 2000/60/EC the European Commission established a framework for the protection of surface, subsurface and coastal waters. The WFD requires Member States to implement all necessary measures to prevent deterioration of the status of surface water bodies, and to protect and enhance the status of surface water bodies. This will also ...


  • Effects of wastewater irrigation on soil properties and turfgrass growth

    Reuse of treated wastewater for turf irrigation is often viewed as one way to maximize existing urban water resources. The aim of this study is to evaluate the applicability of treated wastewater for turfgrass and assess the effects of continuous use of treated water on the soil and crop. Two turfgrass plots irrigated with drinking water and treated wastewater were monitored over a two-year ...

  • Prairie and Turfgrass buffer strips modify water infiltration and leachate resulting from impervious surface runoff

    Concerns over NO3–N concentrations in drinking water and potential subsurface transport of P to surface waters are driving legislation on precautionary N and P application restrictions on turfgrass areas and in recommendations for vegetative plantings within urban environments. Two plant communities and three impervious:pervious surface ratios were examined for effects on leachate water quantity ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • Multi-temporal variation in water consumption of summer maize as determined by the Water Transformation Dynamical Processes Experimental Device

    A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the ...

  • Transport of lincomycin to surface and ground water from manure-amended cropland

    Livestock manure containing antimicrobials becomes a possible source of these compounds to surface and ground waters when applied to cropland as a nutrient source. The potential for transport of the veterinary antimicrobial lincomycin to surface waters via surface runoff and to leach to ground water was assessed by monitoring manure-amended soil, simulated rainfall runoff, snowmelt runoff, and ...

  • Microorganisms as indicators of soil quality

    If we are to monitor soil quality, we need indicators of trends and changes. In order to choose relevant indicators, we must understand the factors controlling soil quality. Soil quality is dependent upon the physical, chemical and biological soil components. The interaction between these components is complex. The chemical and physical components have been more fully investigated than the ...

  • Influence of vermicompost on the physico-chemical and biological properties in different types of soil along with yield and quality of the pulse crop–blackgram

    Long-term application of inorganic fertilizers like high doses of ammonium sulfate and sulfur coated urea has led to soil acidification (Ma et al., 1990), decrease in soil aggregate stability (Estevez et al., 1996) decrease in soil respiration (Sharma 2003), pollution of underground water and decrease in earthworm populations (Edwards and Bohlen 1996). Vermicompost has been shown to have high ...
