Comparing Composts, What Makes Good Compost?

This video is derived from the article: Compost organic matter content varied five-fold and determined compost quality across 107 composts of the North Sea Region https://www.sciencedirect.com/science/arti... This research paper examines the physical, chemical, and biological variations among 107 compost types across the North Sea Region. The study highlights that organic matter (OM) content is the primary driver of quality, significantly influencing microbial biomass, cation exchange capacity, and nutrient levels. Researchers discovered that Belgian composts often feature higher OM concentrations due to strict regional regulations, while farm-produced composts generally harbor more microbial activity than commercial varieties. The analysis also confirms that feedstock materials, such as manure or green waste, dictate the final concentration of nitrogen and phosphorus. By establishing these benchmarks, the authors aim to shift the focus from merely avoiding contamination to actively engineering tailor-made composts for agriculture. Ultimately, the findings emphasize the necessity of individual compost characterization to ensure effective soil improvement and peat replacement.
