Dear back to schoolers,
Good discussion about soils and composts. Peanut shells make a great compost, because they add organic matter and Nitrogen, carbon and spaces for air and microbial activity. All add life to the soil. I don't know about pesticide content - but it would be good to find out before assuming that they pose a significant danger. Does anybody have any such data?
RE: composts. Schools can be making their own composts using school organic wastes, grass clippings, etc. Are schools allowed to have some chickens, as part of an educational program? They could get chicken manure from outsides sources, perhaps.
Some folks at UF and the NCF RCD Council are talking about growing trees that make good fertilizer. We're looking at some species of Leucaena (seedless, non-invasive) that have leaves which are 25% protein and make a good fertilizer, as compost or just laid down fresh as a mulch. You can make a tea from the leaves that is 2% Nitrogen. Their are probably many other legumes that would be good to compost into a good fertilizer - Fava beans grew really well at Highlands last year. Cowpeas,etc.
After this summer, I am also interested in trees or shrubs that provide shade - for both plants and gardeners. Leguminous trees like Leucaena that grow fast, make good wood, add nitrogen to soil, and provide dispersed shading, would be nice. I would like to learn about other plants that serve these kinds of functions.
Schools should maybe start up gardening teams, like sports teams, and compete with eachother in organized events - maybe all have a big booth together at the farmers markets! Students should work/study in school cafeterias preparing fresh foods and learning important life skills. They shouldn't graduate without knowing how to peel a carrot. I think they do such things in other states, like Vermont.
-Dave
