We are lucky to have an excellent composting operation in Rhode Island, Earth Care Farm in Charlestown, and this blog post is about their compost and the upcoming soil/composting workshops at Southside Community Land Trust this Saturday (June 23, 2007) in Providence. Info is on The Providential Gardener Calendar. [Register for these two workshops.]
Plants don't really grow in "dirt." They grow in soil, which is composed of pulverized rock fragments worn down by the weather over long periods of time, clay minerals, and organic matter, which is made up of decaying plants and animals. Soil also contains water and ~ many of us wouldn't guess this ~ air.
Rhode Island soils are mostly light and sandy. For more detail about Rhode Island soil, see the Soil Survey of Rhode Island or attend Southside Community Land Trust's Workshops this Saturday. I'll dish more dirt about soil another time.
Finished, properly prepared compost is beneficial for gardens and significantly improves soil fertility. The above photo shows just one of Earth Care Farm's several huge piles of organic, nutrient-rich materials that include
- farm (and zoo) animal manure
- leaves and wood chips
- fish scraps, shell fish, and seaweed
- coffee grinds, wood ash, vegetable and flower trimmings
The addition of marine byproducts is what makes Earth Care Farm's compost outstanding. This farm's composting methods have been featured in numerous publications (Christian Science Monitor; Rodale's Organic Gardening; People, Places & Plants...). The whole composting process takes 18 months. That backhoe works many hours every day moving and rearranging the piles so that they remain aerated (and don't become smelly), and so that the organic material will continue to decompose.
You can buy a bag of this compost at some local garden centers. But usually you buy it by the cubic yard. Check the website for ordering and purchasing procedures. Also note that Earth Care Farm sells raised bed mix.
