What is Biologically Complete Compost*
What is the difference between Biologically Complete Compost, My Compost,
Commercial Compost, and Bagged or Store Bought Compost?
Biologically Complete Compost, follows the recommendations of Dr. Elaine Ingham. it is organic matter that has been aerobically composted and meets the optimal balance of beneficial soil microbes and limits detrimental soil microbes required for maximum functionality. When microbial components are absent or not in the correct proportions, the natural processes cannot function as Mother Nature intended. We offer custom compost, extracts, teas, and compost making workshops.
Your Compost: most likely what is referred to as a static pile, food scraps, yard debris, etc., piled up and allowed to decompose over time. No testing, no temperature analysis, maybe turning, maybe in an airtight container, maybe allowing air flow. I have tested some real pro backyard composters and some that continuously spread detrimental microbes and weed seeds throughout their landscape. Just remember if it smells it fails. If it dried it died, if its too wet there will be regret. You can use it as mulch but you won't you won't be getting the microbial inoculation your soil needs. Have your compost tested. If you are a home composter bring a sample to a compost clinic and learn how to improve your "Black Gold" this IS money that grows on trees!!
Commercial Compost: Municipal waste management companies receive yard debris from a variety of sources, garbage haulers, highway departments, and residents, so these waste products don't end up in the landfill. Regulated by that State or municipality it must reach and maintain certain temperatures to kill human pathogens and weed seeds. To that end it may be anaerobically processed, at very high temperatures, killing good microbes as well, thus the dark black color of burned material. However, even these temperatures cannot guarantee persistent pesticides or herbicides have been removed. Most persistent herbicides are outlawed for this reason. Or they are SPECIFICALLY LABELED not to allow the plants they were sprayed on to enter the compost stream. Go read your chemical labels. It should not come to you steaming or foul smelling when delivered. That is an indication it has not completed it's break down and can damage plants. Let it sit or put down as mulch not in contact with plants.
Bagged or Store Bought Compost including Potting Soils: READ THE LABEL Buyer beware. There are some very good composters bagging and selling their product. And there are some very bad composters bagging and selling you their toxic waste. Look for the word bio-solids, code for sewer sludge, the muck at the end of sewage processing that may contain toxins and heavy metals. If there is as number to call for lead content call it. Zero lead is the only amount acceptable amount for humans. Organic in the name means nothing, if it came from an animal or human it is considered organic. You get what you pay for. I have seen folks piled up bags of compost for the raised bed gardens that said in small print, "not for use around vegetable gardens".
*What is compost
Compost is a nutrient-rich, organic material that is created through the decomposition of organic matter under controlled conditions, (temperature and time periods) to kill human pathogens, detrimental soil microbes, and weed seeds. It is often referred to as "black gold" because of its value in improving soil health and fertility. Compost is typically used as a soil amendment or organic fertilizer in gardening, agriculture, and landscaping.
Ingredients: Compost is made from a mixture of organic materials, which can include kitchen scraps (such as fruit and vegetable peels), yard waste (like leaves and grass clippings), agricultural residues, and other organic matter like straw or wood chips. These materials are collectively known as "feedstock."
Microbial Activity: The decomposition of organic matter into compost is primarily driven by the activity of microorganisms, including bacteria, fungi, and earthworms. These microorganisms break down the organic materials into simpler substances.
Aerobic Conditions: Composting typically occurs under aerobic (oxygen-rich) conditions. Adequate aeration is essential for maintaining the microbial populations responsible for decomposition. Compost piles or bins are turned or aerated periodically to ensure oxygen is available throughout the process.
Temperature: Composting generates heat as a byproduct of microbial activity. Properly managed compost piles can reach temperatures high enough to kill weed seeds and pathogens. Temperature monitoring is crucial to ensure efficient decomposition.
Time: The composting process can take several weeks to several months, depending on factors like the size of the pile, the type of feedstock used, and environmental conditions. Compost is considered ready when it has a dark, crumbly texture, an earthy smell, and no recognizable organic materials.
Nutrient-Rich: Compost is a valuable source of nutrients such as nitrogen, phosphorus, potassium, and micronutrients. It also improves soil structure, water retention, and aeration.
Soil Amendment: Compost is commonly used to amend soils by mixing it into the topsoil. This improves soil fertility, enhances microbial activity, and helps plants access essential nutrients.
Mulch: Compost can be used as a mulch layer on the surface of the soil. It helps retain soil moisture, regulate soil temperature, suppress weeds, and prevent soil erosion.
Reduced Waste: Composting organic matter reduces the volume of waste in landfills, which can help reduce environmental impact and greenhouse gas emissions associated with landfill decomposition.
Sustainable Practice: Composting is an environmentally friendly practice that supports sustainability by recycling organic waste materials, reducing the need for chemical fertilizers, and improving overall soil health.
Overall, compost is a valuable and sustainable resource that plays a crucial role in enhancing soil quality, promoting plant growth, and reducing the environmental impact of organic waste disposal.
