堆肥
Nutrient density starts with the soil. Nourish the soil 食物 web by creating fertility 从浪费.
堆肥 Ingredients
Nitrogen Materials (N): coffee/tea grounds • 食物 scraps • fresh grass clippings • hair • manure • weeds
Carbon Materials (C): cotton rags • dryer lint • leaves • newspaper • paper products • sawdust • straw •木屑
供应
small bucket or container with a lid • pitchfork/shovel
可选: tarp or infrastructure for collection area • comfrey leaves
方法
1. Designate a compost area in your yard that can store at least 3 cubic feet of material.
2. Collect nitrogen materials. A small bucket or container with a lid works well for 食物 scraps.
3. Add scraps to compost area and cover with carbon materials. 按重量计算, the ideal C:N ratio is about 30:1. 的体积, we recommend starting with equal amounts of C:N, and adjust as you see how the pile 响应. For instance, an armload of dried leaves might offer the same amount of carbon as a handful of sawdust.
4. 包括桩 with a tarp to keep out animals and prevent rain from rinsing out nitrogen.
5. 重复步骤2-4 till the pile is about 3 feet in length/width/height. If available, periodically mix in comfrey leaves. Add water to keep up moisture levels, keeping the pile like a damp sponge. Once the pile is the desired size, stop adding new materials.
6. 把堆翻过来 on a periodic basis to suit your schedule. Ensure the inner core of the pile exchanges places with the outside of the pile during each turning.

Using 完成了堆肥
Bring life to inert soils by spreading ¼ inch of finished compost. 或者厚涂 as a topdressing in garden production areas. Thank you for restoring vitality to our 生命世界.
堆肥 restores structure and nutrients to the soil, increases the ability of plants to absorb minerals, and boosts biodiversity among beneficial bacteria, fungi, and microfauna in the garden.
At Washington College, students can compost 食物 scraps as part of our commitment 零浪费. We support the student-led 堆肥俱乐部 that manages a compost collection area at the campus garden and trains community members in different methods of composting. We’re working to increase organics recycling access on campus and promote composting in the region.
