I just learned of a great new on-line tool from the NRCS. It just went up at the end of last year, and is a bit difficult to use at first, but can be of great interest to chestnut growers, particularly those who are still in the planning stages.
Although the chestnut generally very hardy, and can grow in some “questionable” locations, there are some factors which will definitely not allow for good chestnut growth. Typically, chestnut does not grow well in limestone or calcitic soils, and they also cannot tolerate poorly drained soils or those with poor permeability. Watch out for soils with large amounts of clay, as they tend be poorly drained.
This tool can be a great first look into your land and its suitability for growing chestnuts, or even other species. And since the tool is fairly easy to use and web accessible, it allows quick and professional presentations. Attached is a presentation done by Bill Adamsen of the CT Chapter of TACF on his first try. This took just a few minutes to generate.
A good follow-up to this initial analysis would be to get a soil test done (note this is for those just planning an orchard or those who have already planted an orchard). Even a basic analysis can give you great recommendations on how to manage the property for certain species. Most soil analysis labs don't give recommendations for chestnut, but we usually tell our labs that we're growing blueberries, rhododendrons, or some other species that prefers a relatively acidic soil (pH of about 5.5).
Some land grant institutions still run soil tests (Penn State being one of them). Your local cooperative extension agent would probably have more information on where to get soil samples performed in your area. In some states, it's free, as in Connecticut through CAES. And in other states, like Maryland, you have to go through the Ag Labs somewhere else (MD uses PSU's facilities.
Here's to spring (at least continuous warm weather) coming soon!
