  • Vermicomposting of solid textile mill sludge spiked with cow dung and horse dung: a pilot-scale study

    This paper reports the vermicomposting of Solid Textile Mill Sludge (STMS) spiked with Cow Dung (CD) and Horse Dung (HD) in a six-month pilot-scale experiment employing Eisenia foetida. Growth and fecundity of Eisenia foetida were significantly affected by temperature variations. The lesser number of cocoons and hatchlings were produced in pilot scale experiments than in controlled temperature ...

  • Agronomic impact of earthworms, cow dung compost, vermicompost and chemical fertilisers on growth and yield of brinjal ( Solanum melongena )

    The pot experiment was conducted to assess the impact of live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertilisers and control (without fertiliser) on growth and yield of brinjal (S. melongena). Growth and yield parameters were significantly superior in the pots treated with live earthworms as compared to other fertiliser inputs at 5% level. The plant height ...

  • Research highlights cattle emissions reduction opportunity

    Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...

  • A review of bovine spongiform encephalopathy and its management in Canada and the USA

    Geographic proximity and a long history of integration between US and Canadian cattle industries have resulted in similar management of BSE risk factors. Both countries have had a single imported case of BSE followed by multiple endemic cases of the bovine disease. Comparable risk management strategies have been put in place, such as a ban on the feeding of ruminant materials to other ruminants, ...

  • How the wild rabbit became domesticated

    An international collaboration involving INRA research scientists has evidenced the impact of domestication of the rabbit on its genetic heritage, thanks to sequencing of its genome. In particular, the scientists have shown that the genes controlling brain and neuronal development were specifically targeted by the domestication process. These results, published on 29 August 2014 in Science, help ...

  • Building consumer trust in eco-claims

    As public awareness of climate change increases, we see business and government beginning to rise to the challenge by changing the type of solutions available throughout the market.

What should business ...

  • Evaluation of compost for use as a soil amendment in corn and soybean production

    The purpose of this research project was to 1) evaluate rate of compost application and 2) to compare compost with uncomposted raw material and inorganic fertilizer N application upon maize and soybean growth and productivity, and upon soil characteristics. During the first three years of the study, the source of uncomposted material and compost was food waste and ground newsprint. During years 4 ...

  • Farm digester evolution in Vermont

    In the fall of 2012, Brian Jones of Joneslan Farm in Hyde Park, Vermont spread the first load of manure that had gone through the farm’s new anaerobic digester. “It didn’t smell at all,” recalls Jones. “And we’ve been told that the nitrogen in the digested manure is more available to the plants we grow.” When the Joneslan Farm digester went on line in ...

  • Renewables Make Progress on Many Fronts: Grass Roots Ethanoll from Field Waste

    Progress in community digesters will bring fresh jobs and local control back to farm country - plus offering answers for global warming. FROM THE MIDWEST where native grasses, field waste and wood chips are fueling new biorefineries that are locally-owned to the Northwest where some 50 million gallons of raw manure are producing electricity and dried bedding, community digesters and on-farm ...
