Whole Orchard Recycling: A Sustainable Solution for Central Valley Growers
What is Whole Orchard Recycling (WOR) and Why is it Important?
As California's Central Valley continues to evolve agriculturally, growers are seeking innovative ways to manage their land sustainably. Whole Orchard Recycling (WOR) has emerged as a promising solution, offering numerous benefits for soil health, crop yields, and environmental stewardship. WOR involves grinding old orchard trees into wood chips and incorporating them back into the soil, a practice that is proving to be a game-changer for both soil health and orchard productivity.
How Does WOR Contribute to Soil Health in the Central Valley?
For growers in Tulare, Fresno, Kern, and Kings Counties, WOR offers several key advantages. In particular, a study on almond growth over several years presented remarkable benefits.
Improved Soil Structure: The incorporation of wood chips enhances soil organic matter, leading to better water retention and nutrient availability.
Increased Crop Yields: up to a 19% increase in yields by the ninth leaf in recycled orchards compared to traditional removal methods.
Enhanced Water Efficiency: increase soil water holding capacity by up to 30%, which is crucial in our drought-prone region.
Carbon Sequestration: This practice helps sequester carbon in the soil, contributing to climate change mitigation efforts.
What is Arrowhead Agriculture's Process for WOR?
Arrowhead Agriculture has refined their Whole Orchard Recycling (WOR) process to maximize benefits for growers in the Central Valley. Their comprehensive approach includes:
On-site grinding: Using specialized equipment, they grind entire orchards or vineyards on-site, eliminating the need for hauling and reducing overall project time and costs.
Wood chip spreading: After grinding, the wood chips are spread evenly across the orchard floor. This careful distribution is crucial for ensuring uniform soil benefits.
Soil incorporation: Spread wood chips can be incorporated into the soil, typically to a depth that promotes optimal decomposition and soil health improvement.
Customized solutions: Recognizing that each farm is unique, Arrowhead Agriculture tailors their WOR process to meet the specific needs and objectives of individual growers.
Compliance with regulations: Their methods adhere to local environmental regulations, including those set by the San Joaquin Valley Air Pollution Control District (SJVAPCD).
This comprehensive approach ensures optimal distribution of organic matter for improved soil health, increased water retention, and enhanced long-term productivity of the orchard or vineyard. By handling all aspects of the WOR process on-site, Arrowhead Agriculture streamlines the operation, making it more efficient and cost-effective for growers.
What Are the Environmental and Economic Advantages of WOR?
The environmental and economic advantages of Whole Orchard Recycling (WOR) are significant and far-reaching. From an environmental perspective, WOR aligns closely with California's efforts to reduce agricultural burning and improve air quality. By grinding and incorporating old orchard trees back into the soil instead of burning them, WOR significantly reduces air pollution and greenhouse gas emissions. This practice also enhances soil health by increasing organic matter content, which improves soil structure, water retention capacity, and nutrient availability.
Economically, WOR offers several benefits to growers. Studies have shown that WOR can lead to increased crop yields in subsequent orchards compared to traditional removal methods. The improved soil health resulting from WOR can also lead to reduced irrigation needs and better nutrient retention, potentially lowering input costs for growers over time.
Furthermore, growers implementing WOR may be eligible for various financial incentives. For instance, the San Joaquin Valley Air Pollution Control District's Alternative to Agricultural Open Burning Incentive Program offers cost-share funds to support this practice. These incentives not only help offset the initial costs of implementing WOR but also recognize the broader environmental benefits of the practice.
