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
We have been using 20x60' used billboards which are a bit heavy to move, but are OK with two people once unfolded. They can be dragged from one section to another fairly easily and are heavy enough they don't blow around if a bit of weight is placed at edges. They cost about $100 plus shipping. I think we got ours at https://billboardtarps.com/. Depending on weather it seemed like we got a good kill in about two weeks.
