Valerian / cowpatpit

I ordered a barrel compost kit in the spring for but when I finally got around to using it I, I found that the 507 valerian was not included I thought that a complete kit would have included it but this one did not . Any way I ordered it and aAustin got it to me right away and he answered my questions. On mixing it . I and couple other farmers got together and put together a pit of cowpatpit barbell compost. Looking forward to using it . Keep up the good work.

Chicken POOP-Fly-away

For several years we have been spraying our 1.5 tons of organic compost when we mix our Stack Farms organic chicken poop. Flies gather as the mix is strong. As soon as we spray the pile with you Valerian prep flies are gone and never come back. It is amazing. Thanks.

Incredible

Wow, this is by far the best 507 I've ever used. Incredibly powerful. The Valerian flowers must have been very potent during harvest.

“Liquid light of Saturn” Valerian

After reading Stewart Lundy’s 8/10/25 post re: Venus trine Saturn & Neptune for August 25 & 26th, I ordered Valerian from JPI. I received it by mail VERY quickly. Stewart’s discussion of the “liquid light of Saturn” was inspiring & instructions for making the spray were clear & simple. I am so grateful for JPI!

Agricultural use only: This is a compost preparation for application to compost and crops. Not for human or animal consumption.

One unit is 1 milliliter.

At a Glance:

Biodynamic role:
Used with the complete BD 502–507 compost set; traditionally associated with phosphorus processes and warmth.

How to use:
Use as part of a complete BD 502–507 set. Empty one unit into 1 gallon of lukewarm rainwater or other chemical-free water and stir vigorously for 10 minutes, alternating directions rhythmically. Pour half into the sixth compost-pile hole and spray the other half over the pile in a fine mist. One complete set treats up to 15 tons of compost; use the full set on smaller piles also.

Ingredients:
Valerian blossoms (Valeriana officinalis).

Product Details:

Part of the Biodynamic Compost Set.

BD 507 is the valerian component of the BD 502–507 compost set. An in-vitro study of an Italian BD 507 sample measured Ureibacillus terrenus at 107 CFU/mL and Geobacillus thermodenitrificans at 108 CFU/mL after incubation, compared with a 104-CFU/mL starting inoculum. In a separate Washington State University compost experiment, piles treated with the complete BD 502–507 set showed higher alkaline-phosphatase activity than untreated piles at day 100, a measured phosphorus-related response.

Compost application

Empty one unit into 1 gallon of lukewarm rainwater or other chemical-free water and stir vigorously for 10 minutes. Divide the gallon in half: pour one half into the sixth hole, then spray the other half over the entire compost pile in a fine mist. This is the current handout method for BD 507 as part of the complete compost set.

For frost-season crop spraying, a JPI-reported basil comparison found that BD 507-treated plants had the lowest visible-damage score one week after 18 simulated cold exposures: 1.5/10, versus 3.0 unsprayed and 4.5 water-sprayed. Follow the separate frost-season crop-spray directions; the compost-pile method above uses its own dilution and stirring time.

Frequently Asked Questions

What is the Biodynamic® Valerian Preparation used for?

BD 507 is a valerian-flower preparation used with BD 502–506 in a compost pile. Biodynamic growers use it to support warmth and phosphorus processes. In a 2026 in-vitro assay of an Italian BD 507 sample, two selected compost-associated bacteria grew to 10^7 and 10^8 CFU/mL from a 10^4-CFU/mL starting inoculum. In a separate compost-pile experiment, the complete BD 502–507 set showed higher alkaline-phosphatase activity at day 100 than untreated compost.
How do I use the Valerian Preparation for compost?

Empty one unit into 1 gallon of lukewarm rainwater or other chemical-free water and stir vigorously for 10 minutes. Pour half into the sixth compost-pile hole and spray the other half over the pile in a fine mist.
How much compost does one BD 507 unit treat?

Use one unit as part of a complete BD 502–507 set. One complete set treats up to 15 tons of compost; use the full set on smaller piles also.
What does phosphatase research tell us about BD 507?

Phosphatase helps release phosphate from organic matter. In a 2003 Washington State University compost experiment reported by Jennifer R. Reeve, the complete BD 502–507 set showed higher alkaline-phosphatase activity than untreated compost at day 100 (p = 0.0085). At final sampling, untreated compost measured higher activity (p = 0.0171). The experiment documents a time-specific phosphorus-related response for the complete preparation set, which includes BD 507.
