What is compost?Organic (contains carbon) material that can be used as a soil additive. Comes from decomposing organic household waste and yard waste.
Purpose of CompostCompost is rich in nutrients such as nitrogen, phosophorus, and potassium.Compost protects plants against diseases.Compost provides a neutral pH soil structure for plant growth.
HumusMature compost that has reached a stable level and will not break down any furtherProvides essential nutrients for plant growth and increases water absorptionThis is the end goal we are looking for!
Decompose?Decomposition: process by which organic material breaks down into simpler matter.Decomposers: microorganisms such as bacteria and fungi that aid in the process of decomposition.
LeachateA liquid extracted from compost that contains nutrientsUsed to help plant growth by raising the nutrient levels
How does it work? (strategies/recommendations)MaterialsTemperatureAerationMoistureTIME
1. MATERIALSOrganic materials (containing carbon) can be used in compost.Kitchen scraps: vegetable and fruit waste, coffee grounds, paper, egg cartons, egg shells, etc.Yard waste: grass clippings, leaves, dirt.
Materials that speed up decomposition
Materials that take a long time to break downLarger pieces of wood generally takes a while to decompose.
Materials to avoid:Meat, bones, dairy and fish can be harmfulTrash such as aluminum, plastic, metal, etc. do not decompose and should not be used in a pile.
2. TEMPERATURECompost goes through three temperature phases during the decomposition process ranging from 40-50 degrees Celsius (120-160 F).Compost should be turned so that outer materials can be rotated towards the center of the pile in order to decompose.
*Watch Out*If compost reaches 65 or higher degrees Celsius, that is too hot and may kill the microorganisms decomposing the material.
3. AERATIONIt is important to turn the pile frequently in order to replenish oxygen sources towards the center of the pile.Oxygen is needed by the microorganisms in order to decompose.
4. MOISTUREMicroorganisms thrive in a warm and moist environment.Too much water can block air passage through the compost pile and suffocate the microorganisms.
5. TIMEDecomposition is a lengthy process, and it is important to give the materials time to decompose.Choosing easily compostable materials is key, as is adding organisms such as worms.
DING: Finished!Compost is ready to use when it is a rich brown color and breaks apart easily. It should also have a sweet, earthy smell.Composting can take anywhere between 3-6 months depending on the conditions of the pile, so be patient!
Now your ready to growsome stuff!
