following the instructions from Eliot Coleman’s The New Organic Grower, we have built a compost bin out of straw bales. this method is beneficial because the straw bales contain the heat needed for the materials to break down, while also allowing air flow. we have set up two bins side by side, but the first one just continues to diminish (as it breaks down), so we just keep adding to that one. we also purchased some compost inoculate to add the beneficial microorganisms to the pile and help speed up the decomposition process.
where do we get enough organic material? the compost is a mix of brown (carbon) and green (nitrogen). the green – we compost all on-farm organic waste, including grass clippings and weeds (sans seeds) and spink gets about 50 lbs. of kitchen scraps from his company every day (keeping usable material out of the landfill while making us quality soil amendments!). the kitchen scraps are primarily fruits and veggies (lots of pineapple tops and skins – not sure how well that will decompose) and coffee grounds. we add straw for carbon source and try to mix it together so it all breaks down nicely. we plan to use the compost on the farm to amend the soil.
