  • Biocontained mortality compost using liquid manure

    During disease outbreaks, composting has been used to safely dispose of carcasses and infectious solid manure. However, optimized methods have not been established to use liquid manure (> 80% water content, WC) from dairies as the substrate for mortality composting. In April of 2007, a 3x2 factorial study was conducted in wooden compost bins (240 x 240 x 140 cm) lined with 0.5 mm plastic to a ...

  • Degradation of Methyl Iodide in soil: effects of environmental factors

    Received for publication March 7, 2008. Methyl iodide (MeI) is a promising alternative to the phased-out fumigant methyl bromide (MeBr); however, there are concerns about its environmental fate following soil fumigation. Laboratory experiments were conducted to investigate the effect of various environmental factors on the rate of MeI degradation in soil. The chemical was added to soil at 48.6 mg ...

  • Spatial distribution of some microbial trophic groups in a plug-flow-type anaerobic bioreactor treating swine manure

    Anaerobic digestion of swine manure is carried out by a consortium of microbial species, including volatile fatty acid (VFA) producers, VFA-degraders and methanogens. The distribution of five phylogenetic groups within a plug-flow-type anaerobic bioreactor consisting of eight serially-connected tanks was examined through the sequential digestion of swine manure. Quantification was carried out ...

  • Statistical modelling of the impact of some polyphenols on the efficiency of anaerobic digestion and the co-digestion of the wine distillery wastewater with dairy cattle manure and cheese whey

    The objective of this study was to determine the effectiveness of anaerobic digestion in the treatment of polyphenols (PP) present in olive mill wastewater (OMW) and wine distillery wastewater (WDW). Anaerobic Toxicity Assay (ATA) was conducted to assess the impact of the most representative phenolic compounds present in OMW and WDW: catechol, tannins and p-Coumaric acid, on biogas production. ...

  • Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process

    Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

  • Development of time-temperature probes for tracking inactivation during composting

    Performing compost quality assessment such as compost stability is quite necessary for rating the quality of horse manure and biowaste composts and meeting specific regulatory requirements on the composition and compost process. The aim of this study was to identify an appropriate feedstock composition for use in the production of high quality compost. The objectives were to (1) identify an ...

  • Minimizing Festival Trash

    The Whole Earth Festival at the University of California-Davis is a student-organized event that takes place annually in early May. The weekend attendance is approximately 30,000 people, with 16 food vendors and 100-plus craft booths. One major emphasis of the festival is environmental sustainability. To minimize waste generation, an integrated solid waste prevention strategy was conceptualized ...

  • Burkina Faso farmers lead the way on food security and climate change resilience

    If you want to know how to grow crops in the face of climate change, drought, and land degradation, ask Ousséni Kindo, Ousséni Zoromé, or Yacouba Sawadogo—three farmers in Burkina Faso’s Yatenga region. Policy makers, researchers, and NGO representatives gathered earlier this year at ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture

    Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years. This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable ...

  • Planting trees and managing soils to sequester carbon

    As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...
