Here at Dakota Prairie Composting (DPC), the summer sun fuels a sophisticated process as August unfolds.

• While the season might be winding down for some, our covered aerated static pile (CASP) method of composting is working tirelessly to transform organic materials into premium compost.
• The system creates a rich resource for the end of the growing season and the colder months.

Moisture management is equally crucial, especially as late summer weather can be unpredictable.

• The pile covers help to retain moisture to reduce the need for watering and create a humid environment for our microorganisms.
• This creates a faster and more uniform composting process compared to open windrows.

Around this time, piles started earlier in the summer reach the active composting phase.

• You may see our team doing regular checks, but our composting system minimizes the need for physical turning.
• We can drive oxygen into the heart of the pile, promoting aerobic decomposition throughout.

Once complete, the material is screened with advanced equipment, like our Komptech L3 Star Screener.

• This step removes any plastic, so the final compost product is clean and ready to enrich your soil.
• The screener separates the compost into different sizes—the finest size being our finished product.
• The larger pieces are reintroduced into new piles for further processing.

Looking Ahead: Preparing for Fall and Winter with CASP Efficiency

While our August is busy, we’re also preparing for the seasonal shift with the advantages of the CASP method:

• Optimizing Decomposition for Fall Materials: We anticipate an influx of fall leaves and other carbon-rich materials. The CASP method allows us to create new piles with the ideal blend of “greens” and “browns,” and the controlled environment ensures efficient decomposition even in cool temperatures. The covers retain heat and extend the active composting window.
• Efficient Curing Under Cover: Compost that finishes its active phase in late summer and early fall moves to covered curing piles. Our composting system’s design protects the compost from excessive rain and temperature changes for a consistent supply of well-cured, nutrient-rich compost—ready for fall planting and winter soil conditioning.
• Maintaining High-Quality Stockpiles: Our finished compost is stockpiled and prepared for distribution in the spring. The quality achieved through the CASP method ensures you have access to a premium product.
• Reduced Handling: The static nature of the CASP method minimizes physical handling, making our operations more efficient as we manage larger volumes of fall materials.

At DPC, our CASP method of composting leads to efficiency, quality, and environmental stewardship.

• Our composting process provides a continuous supply of nutrient-rich compost, ready to support healthy growth and soil vitality year-round.
• We’re excited to use the CASP process to create the very best compost for all your seasonal needs!
