  • Chicago Council lists three-decade changes in greenhouse gases and average temperature

    In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

  • Greenhouse packs a power punch

    Closed loop system utilizes gasification, algae ponds and anaerobic digestion to convert wood waste to a variety of products, including biofuel, biogas and a soil amendment. MICHAEL Smith is supervising the first commercial-scale Green Power House at the F.H. Stoltze Land and Lumber Co. near Columbia Falls, Montana. Smith, a physicist, has designed a system to take waste products and turn them ...

  • New routes for roads: using recycled greenhouse films to modify bitumens

    Four recycled greenhouse films made of low density polyethylene and EVA copolymer, are mixed with 6070 penetration grade bitumen. The goal is to improve the viscoelastic properties of bitumen used as a binder in road pavement, contributing to an environment improvement by reducing plastic waste. It is observed that a reasonable stability and a satisfactory upgrading face to rutting defect at high ...

  • Commercial greenhouse water demand sensitivity analysis: single crop case study

    Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

  • Impact on Australia and Pacific Islands of climate change due to enhanced greenhouse effect

    Climate in any particular region of the Earth can change due to many factors. Potentially one of the most significant is changes in atmospheric concentration due to increased emission of greenhouse gases. This could lead to significant changes in temperature and precipitation on a regional basis with significant effects on regional economies and societies. Potential impacts on Australia are ...

  • Fertilizer application timing influences greenhouse gas fluxes over a growing season

    Microbial production and consumption of greenhouse gases (GHG) is influenced by temperature and nutrients, especially during the first few weeks after agricultural fertilization. The effect of fertilization on GHG fluxes should occur during and shortly after application, yet data indicating how application timing affects both GHG fluxes and crop yields during a growing season are lacking. We ...

  • Earth out of sync rising temperatures throwing off seasonal timing

    A newly hatched chick waits with hungry mouth agape for a parent to deliver its first meal. A crocus peaks up through the snow. Rivers flow swiftly as ice breaks up and snows melt. Sleepy mammals emerge from hibernation, and early frog songs penetrate the night. Spring awakening has long provided fodder for poets, artists, and almanac writers. Even for a notoriously fickle time of sunshine, ...

  • Comparison of date-palm wastes and perlite as culture substrates on growing indices in greenhouse cucumber

    Abstract Different substrates have several materials which could have direct and/or indirect effects on plant growth and development. Therefore selecting the best substrate between the ...

  • Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure

    Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...

  • The impact of the oceans heating up

    Following the hottest July and August on record, the earth’s rising temperature is having a number of knock on effects on rising ocean water temperatures around the world. A new study by The International Union for the Conservation of Nature has described rising ocean temperatures as “the greatest hidden challenge of our generation,” and outlined findings that indicate that ...

  • Case study - Peixe Vivo, Brazil

    Seeing the rapid surge of tilapia farming in the Santa Fé do Sul region in Brazil, Emerson Esteves recognized the need to produce high quality PL to support business activity in the area. He founded Peixe Vivo: a medium-scale hatchery specialized in tilapia. A close eye for detail, controlled hygiene and temperature conditions and a thorough perfection of feeding technologies led him to ...

  • Study of agglomeration in 3.5 MW AFBC using rice husk particles

    The combustion of rice husk in fluidised bed combustors seems to be an attractive possibility for power generation in the future, keeping in view the waste disposal problems and the reduction of greenhouse gases. In commercial installations, the occurrence of agglomeration is still one of the main reasons for unscheduled outrages. In this paper, a review of agglomeration mechanism and its ...

  • Case study - Fitmar, Mexico

    Coming from a long line of professional fisherman, the Fitmar family business made a switch from fishery to aquaculture. Seeing aquaculture as a more future proof way of supplying seafood to the local market, this was a very deliberate choice. In order to establish a professional and economically viable model, Fitmar decided to invest a lot of time and effort in optimized hatchery and nursery ...

  • Cross inoculation studies: Response of Vigna mungo to inoculation with rhizobia from tree legumes growing under arid environment

    Cross-inoculation experiments were conducted in the greenhouse to test the rhizobia isolated from nodules of seven tree legumes for their effectiveness in Vigna mungo plants. The tree legumes included Albizia lebbeck, Dalbergia sissoo, Leucaena leucocephala, Pithecellobium dulce, Prosopis cineraria, Prosopis glandulosa and Prosopis juliflora, all growing under arid environment. Rhizobia from ...

  • Quantifying vapor drift of dicamba herbicides applied to soybean

    Recent advances in biotechnology have produced cultivars of corn, soybean, and cotton resistant to the synthetic‐auxin herbicide dicamba. This technology will allow dicamba herbicides to be applied in new crops, at new periods in the growing season, and over greatly expanded areas, including postemergence applications in soybean. From past and current use in corn and small grains, dicamba vapor ...

  • Cropland management techniques for carbon storage

    The Kyoto protocol of 1997 recognises cropland management as a carbon sequestration strategy which may help to mitigate climate change. Under the protocol, ratified by the EU in 2002, member states are obliged to reduce the sum of their emissions of greenhouse gases to 5 per cent below their 1990 levels. Appropriate cropland management may help member countries meet the overall EU emissions ...

  • Seeing Green: Saving Forests or Food Prices?

    A growing population and rapid development will put a strain on land used to grow food over the next century. But if reforestation is used to avoid climate change it will create further strain, says a new MIT study. Written by Vicki Ekstrom.You can read the original new in MIT ...
