Harvest Blend Compost Quality
Engel & Gray, Inc. Regional Compost Facility has become a great resource for
the Central Coast. The facility operators accept organic material from a variety of
sources and perform load checks on each incoming load. Material is analyzed at
a certified laboratory before it is brought to the regional compost facility. Once
it arrives the material is custom blended into windrows (piles) in order for the
composting process to begin under the watchful eyes of the facility operators.
Compost is a natural process in which micro-organisms break down organic
material (leaves, twigs, biosolids & manures) into a dark crumbly soil amendment.
Harvest Blend Compost is manufactured using the aerobic (oxygen requiring)
windrow method. Once the ingredients are mixed, the temperature begins to
naturally rise because of the microbial activity within the pile. The temperatures
are monitored and the piles quickly rise above 131 Degrees Fahrenheit, often reaching 160 Degrees Fahrenheit and
above. The temperatures are monitored daily, and the windrow is turned at least
five times over the next fifteen days to ensure all material is heated. This heat not
only breaks down the organic material, it sanitizes the ingredients, destroying
pathogens and weed seeds that may be present. Through the natural heating
process from this microbial activity, the material breaks down and the composition
of the original feed stock changes to a stable humus product that is rich in
nutrients and micro-organisms.
At Engel & Gray, Inc. Regional Compost Facility we follow very strict criteria when
manufacturing Harvest Blend Compost. We are a fully permitted facility that
follows all County, State and Federal EPA regUlations. The facility has monthly
regulatory inspections by the local health department, who performs the
inspections for the State of California.
Harvest Blend Compost is tested at a certified
laboratory before it is shipped to assure the quality and
safety of the product. Harvest Blend is also registered
with the United States Composting Council Seal of
Testing .Assurance program. Many soil amendments
found have not been tested and composted at a
California permitted facility.
