  • 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 ...

  • Energy and exergy analyses of greenhouse fish drying

    In present study, an energy analysis has been used to predict fish surface temperature, greenhouse room air temperature and moisture evaporated during greenhouse drying of Prawn under natural and forced convection conditions. The predicted values showed fair agreements with experimental values (coefficient of correlation, r = 0.94-0.99; root mean square percent deviation, e = 2.4-10%). Analytical ...

  • Using Data Loggers to Find Cooler Zones in a Greenhouse

    CAS Data Loggers recently provided the data logging solution for a small greenhouse currently cultivating several species of herbs for cooking and medicinal purposes. From potting to product, each variety has to be kept at ideal growing conditions before sale. From his own experience, the owner preferred ...

  • 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 ...

  • Soil genotoxicity induced by successive applications of chlorothalonil under greenhouse conditions

    Greenhouse production of vegetables has been developed rapidly in China. High temperature and humidity inside the greenhouse make this environment more suitable for fast reproduction of fungal diseases. Fungicides are among intensively used chemicals in the greenhouse to prevent crops from the invasive infection of phytopathogen, however, little is known about accumulation of fungicides in ...

  • 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 ...

  • Identification of soybean accessions with high germinability in high-temperature environments

    Soybean [Glycine max (L.) Merr.] seed produced in high-temperature, high-humidity production environments is prone to have substandard germination. Hardseededness, wrinkled seed coats, and infection by Phomopsis longicolla Hobbs are all known to affect soybean seed germinability. Ancestors of modern U.S. soybean cultivars may lack the necessary variability to impart high germinability to new ...

  • 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 ...

  • Tetra–stable bifurcation structure of the climate system of Earth: mechanisms triggering potential transition to the greenhouse steady state

    The emissions of human–made greenhouse gases may trigger transition from the pre–industrial climate to the greenhouse steady state, which was for the last time abandoned 49 million years ago. The study provides an energy balance climate model with temperature–dependent parameters, which illustrates the tetra–stable bifurcation structure of the climate system. Bifurcation structures can evolve in ...

  • 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 ...

  • Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide

    Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

  • Evaluation of convective heat and mass transfer in Open Sun and Green House Drying

    In this paper, a study on open sun and green house drying has been performed to evaluate the convective heat and mass transfer coefficients as a function of climatic parameters. The hourly data for the rate of moisture removal, crop temperature, relative humidity inside greenhouse and outside greenhouse and ambient air temperature for complete drying have been recorded. The experiments were done ...

  • 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 ...

  • 2007 second warmest year on record

    With the record for 2007 now complete, it is clear that temperatures around the world are continuing their upward climb. The global average in 2007 was 14.73 degrees Celsius (58.5 degrees Fahrenheit)—the second warmest year on record, only 0.03 degrees Celsius behind the 2005 maximum. January 2007 was the hottest January ever measured, a full 0.23 degrees Celsius warmer than the previous record. ...
