Premium Johnson-Su Compost

BRING SOIL TO LIFE

We believe that the use of multi-species cover crops combined with Johnson-Su compost extract, together with other regenerative ag practices, can dramatically restore your soil’s life in one growing season. Johnson-Su compost extract provides thousands of beneficial species of fungi and bacteria to restore your soil microbiome.

In 2021 we were inspired to construct our first batch of Johnson-Su bioreactors after seeing a presentation by Dr. David Johnson and Hui-Chun Su Johnson and realizing the potential of this open-source technology to jumpstart the benefits of regenerative agriculture.

Our goal is to produce high quality Johnson-Su compost, provide excellent customer service, and continue to promote the benefits of regenerative agriculture, through development and outreach both within and beyond the regenerative agriculture community.

“When conducting preliminary compost fungal spore counts of nine composts, yours scored the highest of the nine other composts that were analyzed and your compost was even of higher quality than my 4-year compost.”

- Dr. David Johnson

About Kari

Originally from a small town in northwestern Wisconsin’s dairy farm country, Kari was inspired by the faith and service of her parents who worked together at her father’s optometric practice. Her own interests led Kari to advocacy, both for midwifery licensure and disability awareness. Kari obtained her bachelor’s degree in social work in Saint Paul, Minnesota, and found most professionally meaningful her position working with Native elders for a small nonprofit in South Minneapolis before moving to Iowa in 2018.

Learning about Johnson-Su compost and regenerative agriculture started Kari on a journey of discovery about the life of the soil and how to give back to it, something she learned was important during her work with the Native elders in Minnesota.

Kari finds joy in spending time with her family and is passionate about finding connections with the natural world which also lead to greater understanding of ourselves.
