At Keith Dy Ag Services, quality and safety are our top priority. In the past thirty years we have seen many changes in the compost industry, from new blends, organic blends, State registration, licensing, on-site inspections and audits, to increased laboratory testing. We are regulated by CalRecycle Regulations for Compostable Materials Handling Operations and Facilities Regulatory Requirements. These regulations are enforced by the Monterey County Health Department, Environmental Health Bureau. Our compost is licensed with the CDFA which inspects our compost operations and audits our in-house records. Although not all our growers that use our composts are organic farms, we use the same process and procedures for both organic and non-organic products.

Windrow Compost Process Overview

We use the windrow composting process in which compostable material is placed in elongated piles. Materials are brought into the compost site and placed in static piles. Then our blends are premixed and placed into windrows. During the composting period, windrows are monitored for temperature and moisture. The windrows are mechanically turned with a compost turner on a periodic basis to aerate and control temperature. Throughout the 120 day composting process, the active compost must maintain aerobic conditions of 131-170F for 15 days or longer, with a minimum of 5 turnings or more followed my a curing/aging period.
