GreenStart's mission is to foster a resilient energy and food system for New Hampshire by providing technical education and practical agricultural examples. An educational non-profit organization established in 2006, GreenStart sees food and fuel security as the end-product of a vibrant, sustainable agriculture system in New Hampshire.
New Hampshire has 40% of its land area in agricultural soils, yet farms only 10% and imports 95% of its food and fuel. New Hampshire has no significant petroleum resources. To feed and fuel itself from sustainable natural resources, New Hampshire must improve its soils while also improving production.
To achieve this end, GreenStart facilitates projects that
1) increase soil carbon “banking”
2) decrease energy inputs
3) increase both food and fuel outputs (positive energy and carbon balance)
4) promote “tight” cycling of nutrients
5) provide opensource access to appropriate knowledge, seeds and equipment
Here are some images of approaches we use on our farm - everything from the screw in "pencil" dryer fans to drying outside or hoop structure on tarp up to 10 tons. If you have the weather and the quantity isn't that large - it is a very fast and economic way to get grain dry, and is not much labor. We have also used a small bin with a screen bottom and fan (Image is of Cayuga pure organic's dryer). I agree that it would be good to post sources for the bottom screen and fans. I have also heard of using drainage tile inside grain wagons or bins (prior to dumping grain in) used with the pencil type dryers or other fans. I have not had to try that yet, but expect I will at some point.
