Liquid Bone Meal 4-12-0 Storage — Organic Phosphorus Calcium Slurry Tank

Storing Liquid Bone Meal 4-12-0? Start Here

Liquid bone meal 4-12-0 is a thick, brown-to-tan slurry used in organic farming to provide essential nutrients like phosphorus and calcium. It's a slow-release option, making it ideal for organic vegetables, fruits, and specialty crops. This slurry needs continuous or frequent stirring to prevent settling, especially at the suction strainer. It's a popular choice for organic growers due to its compliance with USDA and OMRI standards.

Can you store it in a poly tank?

Yes, you can store liquid bone meal 4-12-0 in polyethylene (poly) tanks. High-density polyethylene (HDPE) tanks are recommended, especially in opaque colors like black or dark green to limit algae growth. These tanks are suitable for both vertical and horizontal setups.

Keep it moving

One key issue with liquid bone meal is its tendency to settle. This requires continuous or intermittent agitation to keep the slurry well-mixed. A cone-bottom tank design is preferred as it allows for complete drainage and easier sediment clearance.

The safety that actually matters

• Use EPDM gaskets for flange seals to ensure compatibility.
• Opt for polypropylene fittings and PVC Sch 80 plumbing for durability.
• Maintain continuous agitation to prevent settling and ensure even nutrient distribution.

Common questions

Do I need a special pump for liquid bone meal?

Yes, a gear or progressive-cavity positive-displacement pump is recommended for handling the slurry.

How should I manage biological growth in the tank?

Using opaque tanks and regular cleaning can help control algae and other biological growth.

Is liquid bone meal suitable for drip irrigation?

Yes, but ensure the slurry is well-agitated and filtered through a 100-mesh equivalent to prevent clogging.
