  • Evaluation of cattle bedding and grazing BMPs in an agricultural watershed in Alberta

    This paper highlights the environmental impacts of implementing beneficial management practices to address cattle bedding and direct access to the creek in a study watershed in southern Alberta, Canada. Approximately 35 cow–calf pairs grazed 194 ha of grass forage and had direct access to the creek in the spring and summer. During winter, the cattle were fed adjacent to the creek at an old ...

  • Sulphur mineralization kinetics of cattle manure and green waste compost in soils

    Sulphur mineralization of cattle manure (CM) and green waste compost (GWC) added to six agricultural soils with different chemical properties was monitored over 10 weeks in a laboratory incubation experiment. Although the amount of sulphur was higher in CM than in GWC, the cumulative SO4 2--S values in GWC-treated soils were higher than in soil amended with CM. The percentages of mineralized S ...

  • Estimation of the increase in deforestation due to agricultural and pastoral activities in the Brazilian Western Amazon: an approach based on the relationship between production and productivity

    This paper presents and discusses the evaluation results of the increase in deforestation verified in the period of 1970 to 1990 in the Cruzeiro du Sul area, Acre State, in the Brazilian Western Amazon, based on an analysis of the relationship between the production and the productivity of the agricultural and pastoral (A&P) activities. The analysis suggests a deforestation increase owing to ...

  • Clean, green and powered by cow patties

    Two dome-like structures rise out of the thick ice fog of a Prairie winter day. From a distance, a science-fiction city seems to be taking shape on the rolling grasslands of east-central Alberta. Then, as you draw near, another sensation takes hold – the oppressively pungent odour of cow manure. On this day, the enveloping fog is making the smell worse than usual, explains Bern ...

  • Concentrations of 61 Trace Elements in Sewage Sludge, Farmyard Manure, Mineral Fertiliser, Precipitation and in Oil and Crops

    This report details the concentrations of over 60 elements in sewage sludge from 48 sewage treatment plants across Sweden; manure from pigs and cattle from 12 farms; the most common NPK and P fertilisers (2 of each sort); precipitation during one year from Gårdsjön in west Sweden; 25 topsoil and 25 subsoil samples from a variety of soil types; and 20 samples of winter wheat grains and 5 samples ...

  • A four‐country ring test of nontarget effects of ivermectin residues on the function of coprophilous communities of arthropods in breaking down livestock dung

    By degrading the dung of livestock that graze on pastures, coprophilous arthropods accelerate the cycling of nutrients to maintain pasture quality. Many veterinary medicinal products, such as ivermectin, are excreted unchanged in the dung of treated livestock. These residues can be insecticidal and may reduce the function (i.e., dung‐degradation) of the coprophilous community. In the present ...

  • Evaluating slurry broadcasting and injection to ley for Phosphorus losses and fecal microorganisms in surface runoff

    The recent growth in the size of dairy cattle farms and the concentration of farms into smaller areas in Finland may increase local water pollution due to increased manure production and slurry application to grass. Therefore, a field study was conducted to monitor losses of total phosphorus (TP), dissolved reactive phosphorus (DRP), and fecal microorganisms in surface runoff from a perennial ...

  • Closed loop system takes manure and methane

    A CONVERSION plant in Mead, Nebraska is processing manure and methane to create ethanol and compost. According to Nebraska Governor Dave Heineman: “This plant sets a new standard for ethanol production in this state and our nation, and is an example of the innovation needed to take this industry to the next level. It lets America get its automotive fuel from the croplands of the Midwest instead ...

  • Saving wetlands through responsible cultivation of soy

    Those consuming tofu and soy milk, but especially meat eaters and those driving a car should keep a critical eye on the impacts of soy cultivation. About 70 percent of soy cultivated is used for animal feed fulfilling the growing meat demands in the world, while the second largest driver of soy expansion is for the use of biodiesel. Whilst recognising these values of soy, its expansion has ...

  • Climate cooperation as development policy: the case Of Costa Rica

    Project-based climate cooperation between industrial and developing countries was first proposed in the early l990s, then under the name of joint implementation (JI). Once in place, this cooperation could lead to a high amount of additional financial flows to developing countries. Nevertheless, many NGOs and developing country representatives were in the beginning very sceptical about JI and ...

  • Digging for data on Africa’s climate future

    The cardboard box is covered with a layer of dust so thick it must have been tucked away in this Kenyan basement for decades. The researcher wipes off the dust and rummages through the papers stored inside by someone long since retired. Sheet after sheet of neatly typed paper emerges, the faded rows of numbers detailing rainfall, temperature and wind speed. In a way, the researcher is hunting for ...

  • Tapping the potential of codigestion

    Codigestion refers to processing multiple biodegradable substrates (feedstocks) in an anaerobic digestion (AD) system. A more contemporary definition refers to the digestion of a combination of select biodegradable feedstocks with a base substrate that an AD system was designed to handle. The intent is to maximize the production of biogas (i.e., renewable energy) by adding substrates that produce ...

  • Soy Cultivation in South America

    The expansion of soy bean Soy cultivation has shown an increasing expansion throughout Argentina, Brazil, Bolivia and Paraguay, in the last decade. This remarkable increase is explained by its economical importance in the region, and as a consequence, it is difficult to regulate its progress and attenuate its potential socio-environmental impacts. In 2012, in these 4 countries the ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...
