ASSURING
COMPOST ANALYTICAL PROFICIENCY An efficiency program known as CAP has been established for labs that routinely handle compost materials to ensure that acceptable methods are used. |

REDUCING
GREENHOUSE GAS EMISSIONS HOW COMPOSTING AND COMPOST CAN OPTIMIZE LANDFILLING P. Lechner, C. Heiss-Ziegler and M.H. Humer Pretreatment of organic residuals by composting and applying a cover layer of compost are found to reduce methane escape from landfills. |

COMPARING
CONTROL STRATEGIES USING LIME TO REDUCE ODORS FROM BIOWASTE COMPOSTING Henrik Lystad, Jan P. Hammer, Roald SÆrheim, Ove Molland, Ove Bergersen and PĀl Smits Method developed in Norway is applicable for many composting technologies where low pH and VOC emissions present a problem. |

EFFECTS
OF TURNING AND FEEDSTOCKS ON YARD TRIMMINGS COMPOSTING Frederick C. Michel, Jr. Yard trimmings compost processing costs may be optimized by turning weekly or even monthly. However, if land costs are high or odors are an acute problem, daily turning may be preferable. |

WHO
GETS THE NITROGEN? COMPARING COMPOSTED YARD TRIMMINGS AND GROUND WOOD AS MULCHES John E. Lloyd, Daniel A. Herms, Benjamin R. Stinner and Harry A.J. Hoitink Research measured the effects of a surface-applied compost versus a wood mulch on soil microbial activity, nutrient cycling, and growth of ornamental plants. |

MARKET
REQUIREMENTS GRAPPLING WITH COMPOST QUALITY DOWN UNDER K. Wilkinson, R. Paulin, E. Tee and P. O’Malley Composters and researchers need to develop standards to accelerate use of sustainable compost-based agricultural production systems in Australia. This may lead to stricter control of feedstock consistency and composting conditions. |

LONG-TERM
EFFECTS RESEARCH PROJECTS ANALYZE COMPOST IMPACT W. Hartl and E. Erhart Studies at Biological Agriculture Institute in Vienna, Austria provide valuable knowledge of effects of compost on crops and soils, including water economy, nitrogen dynamics, micronutrient and heavy metal contents, and increased yields. |
