  • Terra Preta sanitation: re-discovered from an ancient Amazonian civilisation – integrating sanitation, bio-waste management and agriculture

    The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had ...

  • Altered levels of endocrine biomarkers in juvenile barramundi, Lates calcarifer (Bloch), following exposure to commercial herbicide and surfactant formulations

    Agricultural pesticides that are known endocrine disrupting chemicals (EDCs) have been detected in waters in the Great Barrier Reef (GBR) catchment and lagoon. Altered transcription levels of liver vitellogenin (vtg) have been documented in wild populations of 2 GBR fisheries species, and were strongly associated with pesticide‐containing run‐off from sugarcane plantations. Here, we examine ...

  • Methane and carbon dioxide emission from two pig finishing barns

    Received for publication July 22, 2007. Agricultural activities are an important source of greenhouse gases. However, comprehensive, long-term, and high-quality measurement data of these gases are lacking. This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and ...

  • Effects of atrazine on endocrinology and physiology in juvenile barramundi, Lates calcarifer (Bloch)

    Exposure to certain environmental contaminants such as agricultural pesticides can alter normal endocrine and reproductive parameters in wild fish populations. Recent studies have found widespread pesticide contamination across the rivers that discharge into the Great Barrier Reef lagoon. Potential impacts on native fish species exposed to known endocrine disrupting chemicals such as atrazine, ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
