USE.215-Effect of Composts on Microbial Communities in Potting Media-AC22.CREF

Composts are increasingly used as components of growing media for greenhouse, nursery and garden crops. While they are known to improve chemical, physical and biological properties that impact plant health, little is known about the specific effects of compost amendments on the composition of microbial communities in these media. In this study, microbial consortia were… Continue reading USE.215-Effect of Composts on Microbial Communities in Potting Media-AC22.CREF

PRO.215-Development of Detailed Bioassays for Persistent Herbicides-AC22.CREF
