Bloom is often asked about its odor characteristics, which is a somewhat subjective matter. With the assistance of Maryland Environmental Service (MES), Bloom recently gathered soil amendments commonly used in the agricultural and landscaping community to compare odor profiles in a more systematic and objective manner.

This process included a blind “nose calibration” to determine personal sensitivity levels, and concluded with field readings of nine different products. Products were ranked by three participants according to odor strength using Nasal Ranger-brand olfactometers, and qualitative descriptors were also collected for each product.

“Based on this experiment, Bloom product odor qualities are shown to be on par with other organic materials commonly used as soil amendments in agriculture and landscaping. Results can vary based on sensitivities and sensory perspectives, however, in our results, chicken litter had the strongest odor intensity,” concluded the MES report.
