The 7th grade gardening classes built three compost screens. Throughout the year we collect compost from the cafeteria, the woodworking room and the business office. We also collect weeds, grasses and leaves from our campus. All together we have a mix of materials that take different periods of time to decompose. The compost screen is designed to fit the standard wheelbarrow. Simply lay the screen on top of the wheelbarrow and shovel your compost pile onto it. The finished decomposed material will fall through the screen while the materials that need more time will sit on top waiting to be dumped back into the compost pile. Of course we finished our day with a freshly harvested mixed green salad from the garden, with lemon, olive oil and salt! Delicious……… and extremely nutritious!
