Resources & Further Reading

Where to go deeper. Links are to organizations and documents widely used in the composting field; availability and editions change, so search titles where needed.

Foundational handbooks

• On-Farm Composting Handbook — NRAES-54, Cornell. The classic North American farm-scale reference: siting, recipes, equipment, economics.
• Field Guide to On-Farm Composting — NRAES-114. Pocket-format companion to NRAES-54.
• The Composting Handbook (2022) — the long-awaited successor to the On-Farm Composting Handbook; comprehensive and current.
• Compost Utilization in Horticultural Cropping Systems — Stofella & Kahn (eds.). The science of use in crops.
• Teaming with Microbes — Lowenfels & Lewis. Accessible soil-food-web context for compost's biology.

Standards & test methods

• TMECC — Test Methods for the Examination of Composting and Compost (US Composting Council). The lab methods bible.
• US EPA 40 CFR Part 503 — biosolids pathogen/metal rules; source of PFRP time–temperature standards.
