WATER CONSERVATION
- A pipeline was installed at Hartley Produce in Prosser, WA, to transport water from the Columbia River to surrounding farms. This pipeline conserves water by eliminating evaporation during irrigation as water moves between fields. 
- At several of our farms, we use drip irrigation, which delivers water directly to the roots of the onions. This method conserves water and promotes healthier, more robust plant growth. 
SEED SELECTION
Selecting the right seed is essential for crop success and sustainable farming. Here are a few key considerations:
- Choose seed varieties that are best suited to produce high-quality onions 
- Aim for optimal yield to maximize production while conserving land 
- Keep detailed records of seed varieties and vendors for consistency and traceability 
SOIL HEALTH
Each crop, including onions, is susceptible to specific diseases and weeds. To conserve soil health, we implement the following practices:
- Crop rotation to prevent disease buildup and improve soil fertility 
- Use of cover crops and no-till methods whenever possible to protect soil structure 
- Regular soil sampling to ensure optimal planting conditions 
- Application of a state-of-the-art, certified organic laser weeder (where applicable), which reduces chemical use, protects beneficial insects, and minimizes soil disturbance 
PACKAGING
Onions 52 is committed to adopting sustainable packaging whenever feasible. We currently use reusable plastic containers (RPCs) and reusable pallets (CHEP, PECO) to help reduce excess waste and minimize our environmental impact.
ipm certified
At Onions 52, we're committed to protecting pollinators like bees and butterflies—essential partners in growing healthy crops. Through sustainable farming practices and a focus on reducing chemical use, we're on track to achieve IPM (Integrated Pest Management) certification at every farm by the end of 2025. It’s all part of our mission to support pollinators and protect the planet.
