  • Fenton's treatment of actual agriculture runoff water containing herbicides

    This research was to study the efficiency of the Fenton's treatment process for the removal of three herbicides, namely 2,4-dichlorophenoxy acetic acid (2,4-D), ametryn and dicamba from the sugarcane field runoff water. The treatment process was designed with the Taguchi approach by varying the four factors such as H2O2/COD (1–3.5), H2O2/Fe2+ (5–50), pH ...

  • Phosphorus runoff from wastewater treatment biosolids and poultry litter applied to agricultural soils

    Received for publication March 19, 2009. Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids ...

  • Agroforestry Buffers Reduce Runoff from Agricultural Watersheds

    Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective of this study was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop ...

  • The CAMBI process and agriculture, a sustainable solution?

    Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

  • Canarina DESCAR software · agricultural wastewater · commands 7

    XY-Plane (parallel to water surface): In such a case, the program window is a XY-plane (parallel to the water surface). A pollutant point source (outfall pipeline) is represented by a small square. In the Status bar at the bottom, we have X,Y and Z coordinate values in meters and data on our environmental system. Point the mouse where you want in ...

  • Persistence of the tricyclic antidepressant drugs amitriptyline and nortriptyline in agriculture soils

    Amitriptyline and nortriptyline are widely‐used tricyclic antidepressant drugs. They have been detected in wastewater, surface runoff, and effluents from sewage treatment plants. As such, they could potentially reach agriculture land through the application of municipal biosolids or reclaimed water. In the absence of data on their fate in the environment, the persistence and dissipation ...

  • Effects of agricultural production on phosphorus losses from paddy soils: a case study in the Taihu Lake Region of China

    A field plot experiment was conducted on two types of paddy soils in the Taihu Lake Region of China from June 2000 through 2002 to assess phosphorus (P) losses by runoff and drainage flow and the effectiveness of rice–wheat double cropping on reducing P losses from paddy soils. Commercial NPK compound fertilizer and single superphosphate fertilizer were applied to furnish 0, 30, 150, and 300 kg P ...

  • Sorption, uptake and biotransformation of 17β‐estradiol, 17α‐ethinylestradiol, zeranol and trenbolone acetate by hybrid poplar

    Hormonally active compounds may move with agricultural runoff from fields with applied manure and biosolids into surface waters where they pose a threat to human and environmental health. Riparian zone plants could remove hormonally active compounds from agricultural runoff. Therefore, sorption to roots, uptake, translocation, and transformation of three estrogens (17β‐estradiol, ...

  • Mitigation options for sediment and phosphorus loss from winter-sown arable crops

    Received for publication January 20, 2009. Sediment and P inputs to freshwaters from agriculture are a major problem in the United Kingdom (UK). This study investigated mitigation options for diffuse pollution losses from arable land. Field trials were undertaken at the hillslope scale over three winters at three UK sites with silt (Oxyaquic Hapludalf), sand (Udic Haplustept), and clay (Typic ...

  • Spectral Reflectance Properties of Winter Cover Crops in the Southeastern Coastal Plain

    Conservation tillage is a commonly adopted best management practice for reducing runoff and erosion, and increasing infiltration. Yet current methodologies in place to monitor conservation tillage adoption are largely inappropriate for regional or national assessments. A major goal of this study was to evaluate the spectral response properties of four alternative winter cover crops using remotely ...

  • Boosting Compost Markets : Iowa Studies Ways to Control Highway Erosion

    EROSION during and after road construction creates large amounts of silt, which deteriorates water quality and causes ecological problems. Iowa agencies continue to conduct studies to verify the value of compost as an economical way to prevent runoff along the state’s 100,000 miles of roadway. Next month will begin the second half of a two-year research project that involves the Iowa Department ...

  • Can nutrient trading shrink the Gulf of Mexico`s dead zone?

    The Gulf of Mexico has the largest dead zone in the United States and the second-largest in the world. Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life. The Gulf of Mexico dead zone can ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

    OPTIONS FOR MANAGING COMPOST LEACHATE DURING EXCESSIVE RAINFALL CONDITIONSAn Information Sheet prepared by The Composting Association in the United Kingdom gives an overview of available options for managing “liquor” (leachate) produced at composting sites - especially following the excessively rainy spring/summer of 2007. “Compost leachate” can be described as water that has changed in ...

  • New study finds recycled phosphorus could fertilize 100 percent of U.S. corn

    The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves ...

  • Implementing Research : Georgia Takes Many Routes to Recycle Food Residuals

     PETROLEUM HYDROCARBON LEVELS “One unique local characteristic (and treatment difficulty) we encountered in our composting program,” says Stan Konno, PWC environmental department director head, “is the high level of diesel range total petroleum hydrocarbon (TPH) content in the sludge from the WWTF at Fort Kamehameha.” Oil from past leaks in pipelines and tanks — which go back to 1941 — ...

  • Pesticides in the European Union

    There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...

  • Marine Resources : Chitin Research Opens Up Crab Shell Profits

     Building Human Resources Instead of Landfills “The product originally designed was a chipboard four-drawer dresser that retailed for $20,” explains McDonald. The material used was chipboard “blows” or imperfect boards that would normally go to the dump. While durable, it was suitable only for garage or storage use. Manufacturing this dresser allowed the woodshop to learn the process and ...
