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.
