Welcome to a weekly podcast with longtime Anchorage Daily News garden writer and author Jeff Lowenfels, and co-hosted by Jonathan White. Think of it as a companion to Jeff’s weekly columns and his popular series of books. Join Jeff and Jonathan as they dive deep into organic gardening and the soil food web — breaking down the science, giving expert gardening advice and busting those long-held myths about how to help your garden grow.
This episode: A plant’s exudate attracts bacteria and fungi, and they feed the plant when eaten by other soil food web members. They also build important soil structure. Bacteria and fungi attracted by the plant are, in turn, eaten by nematodes and protozoa.
All this results in production of nitrogen to feed the plant. But it turns out there are two kinds of nitrogen a plant can use: ammonium and nitrates. Some plants prefer one or the other, depending on how long the plant has been in the ground.
The show also includes special mention of the importance of applying mycorrhizal fungi this time of year and the reasons why.
