Evaluating a prospective vineyard site

Tom DeWitt helped us evaluate soil pits on August 11 in order to see if a particular site would accommodate a vineyard or if modifications, like berming down the row, were necessary. Luckily the site preferred by Dr. Hwang for his grapes proved to be a good prospect for grape production – at least a 2 foot deep rooting zone and good internal water drainage since the fragipan in these pits was weak. Dr. Sara Lancaster, Jennifer Morganthaler and Jeremy Emery helped with the evaluation. The pits will remain open for Dr. Lancaster’s class to come out and evaluate as well.

Tom DeWitt evaluates the soil pit and interprets it for us.

Kidfest at the Mountain Grove Fairgrounds

We set up the Missouri State Fruit Experiment Station display at the 2016 Kidfest today and partnered with Paul Anderson, a member of the Beekeepers Association of the Ozarks who set up an observation hive. The bean bag toss into the mouths of a green June beetle or an apple colding moth larvae were a big hit.

Kids toss bean bags into the mouths of either an apple codling moth larvae or a green June beetle.
