  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • Nutrient analysis system keeps wastewater plant in control - Case Study

    Problem The Denver, Colo., Metro Wastewater Reclamation District wanted near real-time nutrient analysis for a very challenging headworks wastewater aeration process, consisting of a combination of centrate and RAS. The centrate and RAS reaeration basin (CaRRB) effluent is added to primary effluent prior to mainstream aeration. Solution ASA Analytics supplied ...

  • 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 ...

  • 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 ...

  • Control of Microthrix parvicella by aluminium salts addition

    Aluminium and iron chloride were added to a biological nutrient removal pilot plant (1,500 population equivalent) treating urban wastewater to investigate the control of Microthrix parvicella bulking and foaming by metallic salts. Monitoring plant performance over two 6-month periods showed a slight impact on the removal efficiencies. Addition of metallic salts (Me; aluminium or aluminium + ...

  • 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 ...

  • Ammonia sanitization of blackwater for safe use as fertilizer

    Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

  • 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 ...
