Final Report – Increasing Supply and Quality of Local Storage Vegetables

We recently completed a project aimed at improving the ability of Vermont vegetable farms to store crops such as beets, carrots, parsnips, potatoes, onions, squash and sweet potatoes, all of which have unmet demand in late winter when local supplies run out. The physiology of these crops allows them to be stored for many months […]

Doser for Small Scale Vegetable Washing with Sanitizer

I recently put together a simple doser for manually measuring accurate doses of sanitizer into wash water solutions.  It is really just a homemade burette. The process of mixing a treatment dose of santizer requires metering a specific dose of concentrate into a larger volume of water.  I have also created a calculator to help with […]

Simple DIY Outside Air Exchange

In colder climates winter storage crops have been stored in passive root cellars for centuries, striking the balance between outside conditions and storage conditions.

Outside air exchange systems use an […]

1944 US Office of Education video on refrigeration principles.  Excellent.

Practical Produce Safety – April 11, 2013 – Vergennes/Monkton

Had a great time talking about all the ways we can get sick from produce related pathogens yesterday.  The good news is that the bulk of the workshop was focused on ways to mitigate the risks. The Practical Produce Safety workshop series coordinated by Ginger Nickerson (UVM Center for Sustainable Agriculture) and Hans Estrin (UVM […]

CoolBots(TM): Inexpensive Cold Storage

Demand for on-farm cold storage of produce and other Vermont agricultural products is increasing as local markets for these goods expand. I receive many inquiries regarding CoolBotsTM, an adaptation of a window air-conditioner to make a cooler out of an insulated space. This article is intended to collect related resources in one place and to […]
