1. Stage 1 – Mesophilic Phase: This initial phase occurs at temperatures ranging from 70°F to 90°F (21°C to 32°C). Mesophilic microorganisms break down readily available sugars, starches, and proteins in the horse manure, resulting in a rise in temperature. It is crucial to monitor moisture levels and ensure proper aeration during this phase.
2. Stage 2 – Thermophilic Phase: As the temperature of the compost pile increases, thermophilic microorganisms become dominant. This phase typically ranges from 130°F to 160°F (54°C to 71°C). High temperatures help break down complex organic compounds, kill weed seeds and harmful pathogens, and accelerate decomposition. Maintaining adequate moisture and aeration is essential during this phase.
3. Stage 3 – Cooling Phase: After the thermophilic phase, the temperature gradually decreases as the readily available organic matter is consumed. The compost pile begins to cool down, signaling the end of active decomposition by thermophilic microorganisms. This phase allows mesophilic organisms to recolonize and continue decomposing the remaining organic matter.
4. Stage 4 – Maturation Phase: During this final stage, the compost undergoes further breakdown and stabilization. The temperature steadily decreases, and the compost develops a dark, earthy smell. The compost becomes crumbly and resembles rich, fertile soil. This mature compost is ready to be used in gardens, fields, or potted plants.

The duration of each stage can vary depending on factors such as external temperatures, compost pile size, carbon-to-nitrogen ratio, and management practices. Generally, the composting process can take anywhere from a few weeks to several months to complete.

By monitoring the temperature, moisture levels, and regularly turning the compost pile, you can promote faster decomposition and ensure the production of high-quality compost. Patience and active management are key to successfully navigating the composting process and obtaining nutrient-rich compost for your gardening or farming endeavors.
