Fermentation

I think, that the Biodynamic Pfeiffer Compost Starter is really miraculous, taking in consideration not only how much work it takes to create them, but also maybe love and enthusiasm, that eventually comes to light if you touch anything in nature.
Each time I pass by one of my compost piles I can’t help, that sweet smell of fermentation really draws me in that direction or I even was able to smell it from my backyard patio.

Thank you so much! We'd love to see a picture. We can almost smell it from here!

Although each batch I get is somewhat different, my finished compost always turns out digested. My customers won’t let me retire!

You are absolutely correct! Each batch is its own dynamic living thing and no two are exactly the same. Nonetheless, we add back portions from previous batches -- all the way back to Hugh Courtney's time! -- to guarantee an inherited legacy. It is our hope that they always service you well. Thank you, as always, for your support and your work healing the earth.

Pfeiffer Compost Starter

I have used the Pfeiffer Compost Starter for almost 30 years. Wouldn't seem right to not use it. My compost goes through a two year cycle to finished compost and is far superior to the store bought varieties.

Compost pile?

As a widowed elderly woman I feel overwhelmed by the idea of building a compost pile. I do have a tumbler though that my kitchen scraps decompose in. To read that I can put the compost starter in a saltshaker and sprinkle some over my kitchen collection of scraps made me so happy! Thank you for this idea that can meet me where I am right now!

Yes, in my backyard !!!

The compost starter and spray are also perfect for those who can only work on a small scale. I use it on my yard and spread some around the parks near me.

I have used it for many years in my small compost pile; it does help breakdown the materials I put into it.

Published results & practical experience

A practical way to bring biodynamic preparations into your composting routine.

Pfeiffer Compost Starter is a prepared inoculant for compost materials. Published accounts describe its use in garden heaps and farm windrows, offering practical examples of the product at work.1, 2, 3

A garden-heap comparison

In a report published in English in 1967, Katharina Hanke compared two heaps made from the same plant wastes. One received Pfeiffer's B.D. Compost Starter; the other received the individual biodynamic preparations.

After five weeks Heap No. 1 was completely rotted, while Heap No. 2 was still in the midst of the process.2

This was a two-heap observation, with one heap per treatment and no untreated heap. “Completely rotted” was the author's assessment. When the finished composts were used for lettuce and kohlrabi, she observed no difference in growth or total production.2

A farm windrow routine

Patricia Smith's 2003 interview with Joe Francis describes three windrows of roughly fifty tons each, built from cow manure and hay. Francis used Compost Starter during construction and turned the material every seven days. The account reported compost ready for use after twenty-one days.3

The timing belongs to that farm's materials and management. The interview does not provide an untreated comparison or a standardized compost-maturity test.3

Put the experience to work

Use the current product instructions to prepare and apply Compost Starter. Keep track of your feedstocks, moisture, turning dates and progress toward readiness. Published experiences provide useful comparisons for your own composting routine.12

Frequently Asked Questions

How do I use the Biodynamic Pfeiffer™ Compost Starter?

Moisten one unit in a flat pan or dish with just enough water to make it pasty. Allow it to activate for 12–16 hours or overnight, then dilute the paste in enough water to thoroughly moisten each compost-pile layer as the pile is built.
What are the benefits of using the Biodynamic Pfeiffer™ Compost Starter?

JPI Starter brings BD 500, all six BD 502–507 compost preparations, and beneficial microbial cultures together for an actively managed pile. In a controlled 2026 comparison, compost treated with the included BD 502–507 set supported greater growth of tested compost-active bacteria at 120 days than corresponding untreated compost, especially in a mixed plant-and-manure pile. As the pile matures, look for these practical quality cues from JPI: a woodsy smell, uniform dark-brown color, and soil-like texture. Study: https://doi.org/10.1186/s40538-025-00891-y
How much compost can one ounce of Pfeiffer™ Compost Starter treat?

One ounce can treat approximately 1 to 1.5 tons of compost material, which is around 1.5 to 2.25 cubic yards.
What makes the Pfeiffer™ Compost Starter unique?

It combines BD 500, the complete BD 502–507 compost-preparation set, and beneficial cultures in one easy-to-distribute, one-ounce Starter. Activate it as a paste for 12–16 hours or overnight, then dilute and distribute it through each layer as the pile is built. One unit treats about 1–1.5 tons of starting compost material.
