In the video, Farmer Jesse discusses the challenges of sourcing good compost and the rising costs, leading him to build a static aerated compost system, which requires no turning and can be done without a tractor. He explains the components, setup, and benefits of this system, aiming to make NOP-compliant compost for his farm while reducing labor and costs.

Creating a Static Aerated Compost System: A Step-by-Step Guide

Introduction

Hey everyone, Farmer Jesse here! Today, I want to share our journey of building a static aerated compost system, also known as an Aerated Static Pile (ASP). This project stems from our need for reliable, nutrient-rich compost to feed our soil. Over the years, we’ve faced challenges with sourcing trustworthy compost, and with rising costs, we’ve turned to making our own. Let’s dive into the details of this system, which doesn’t require a tractor and meets organic certification standards.

The Importance of Good Compost

Having access to high-quality, trustworthy compost is crucial for any grower. On our farm, compost serves as our primary mulch and is essential for starting garden beds. Last year alone, we used around 120 yards of compost on three-quarters of an acre to get our farm up and running. However, the cost of compost has significantly increased, compelling us to produce more compost ourselves.

Challenges in Compost Production

Lack of Equipment

One major challenge is that we don’t own a tractor, which makes moving and turning large amounts of compost difficult.

Organic Certification Requirements

As a certified organic farm, we can only use National Organic Program (NOP) compliant compost. This means our compost must adhere to specific guidelines, which I’ll explain in detail.

Building the Static Aerated Compost System

Why Static Aeration?

I’ve always wanted to create a static aerated compost system. This method requires no turning and theoretically speeds up the composting process, making it ideal for our needs.

Components of the System

1. PVC Pipes and Manifold: We used approximately 17 feet of large PVC pipe for the manifold, with four-inch pipes being sufficient but six-inch pipes providing better airflow. We also needed 90-degree elbows and T-couplings to piece it all together.
2. Drainage Pipes: Four 12-foot lengths of four-inch perforated drainage pipes were used. While buying pre-perforated pipes was convenient, drilling your own holes might offer better airflow control.
3. Blower: A bouncy house blower was used to provide the necessary airflow through the compost pile. This blower is connected to a programmable cycle timer to manage airflow intervals.
4. Housing for Blower: We housed the blower and timer in an old tote to protect them from rain, ensuring there’s ample ventilation to prevent motor wear.
   

   Setting Up the Compost Pile

    

5. Base Layer: Start with a few inches of wood chips to help distribute oxygen evenly in the pile.
6. Layering Material: Pile your compost materials in layers over the pipes. Ensure you maintain the right carbon to nitrogen ratio (e.g., 30:1) for efficient composting.
7. Watering: Water is crucial for microbial activity and maintaining the compost’s moisture level. Make sure to water the pile thoroughly.
8. Monitoring: Use a long temperature composting thermometer to track the pile’s temperature. This helps ensure the compost reaches the necessary heat levels to kill weed seeds and pathogens.
9. Covering the Pile: Cover the pile to retain heat and moisture, aiding the composting process.
   

   Organic Certification Compliance

   To comply with NOP standards, compost containing manure must follow specific temperature and turning protocols. For windrow systems, temperatures must be maintained between 131°F and 171°F for 15 days, with the pile turned five times. For static aerated piles, the same temperatures must be maintained for three days with no turning required. This system meets these guidelines, allowing us to use the compost within 90 days of harvesting crops.

   Conclusion

   Building a static aerated compost system has been a game-changer for us. Although it requires some initial setup and labor, the benefits of producing our own high-quality, organic compost are immense. This system is scalable and can potentially save us thousands of dollars annually. If you’re facing similar challenges with compost, I highly recommend giving this method a try.

   Thank you for joining me on this composting journey. If you have any questions or suggestions, feel free to leave them in the comments. Happy composting!
