This video introduces Bloom, DC Water’s Class A Exceptional Quality biosolids fertilizer and soil amendment, from process to end product.

Veteran horticulturalist Ron Alexander presents on practical, locally grounded strategies to manage stormwater and build greener, more resilient communities.

Leading researchers share new findings on the behavior and impacts of PFAS in land-applied biosolids, from soil concentrations to plant uptake.

This presentation by Dr. Sally Brown, biosolids researcher from the University of Washington, summarizes her decades of research into the benefits of biosolids for soils, crops and the climate. As Sally says, “When you fertilize with biosolids you are getting the nitrogen that plants need. But the biosolids package comes with so many extras that your plants are likely to thank you and thank you again!” This webinar is of interest to anyone already using biosolids or interested in improving their soils with biosolids; Sally makes soil science accessible and engaging to participants of all backgrounds and knowledge levels.

Sally Brown is a research professor at the School of Environmental and Forest Sciences at the University of Washington. A PhD graduate of the University of Maryland, Sally has over 20 years of research experience on diverse aspects of biosolids and composts, including risks and benefits. She is a former board member of both the US Compost Council and Soil Science Society of America, and served two terms on the National Academy of Science Standing Committee on Soil Science. Sally has co-edited two books on urban agriculture.

What is dry versus wet weight? What’s a good C:N ratio? How can I figure out what to look for in a compost or fertilizer nutrient analysis based on my soil test? Nutrient analyses can be confusing to even industry professionals, let alone casual gardeners, but important to understand if you want to be confident in the products you’re putting on your lawn and garden.

This how to webinar with horticulturalist expert Ron Alexander covers the basics of nutrient analyses, using recent examples from Bloom’s own product analyses.

Confusion abounds when it comes to questions of availability and movement of nutrients from soil amendments. Bloom fields many questions about runoff concerns, plant available nutrients, mineralization rates and of course, the P word – phosphorus, a contentious topic in the world of nutrient management. In this webinar, horticulturalist and organics expert Ron Alexander breaks down frequently asked questions by farmers, landscapers and home gardeners, and shares results of a growing body of research on nutrient movement of biosolids specifically.

Learn how to feed, fertilize and rejuvenate soil, whether that’s in a container, a grow box or a raised bed. Soil is the foundation of garden success–learn how to amend your soil, and feed it for the season.
