- Since 2012 we have helped thousands of people from all over the world understand their soil tests and remineralize their soil.
- OrganiCalc, our DIY web app, turns a Logan Labs soil test into practical amendment recommendations.
- All of our amendment recommendations are certified organic.
- Remineralization helps organic growers grow nutritious plants that are healthy for the body and the soil.
- We offer soil, saturated paste, and water testing through Logan Labs, along with custom analysis and interpretation.
- This website is full of practical information to help you to grow better plants.
Soil mineral balance is not everything you need to grow great crops, but having balanced minerals can make everything else easier.

Our approach to soil re-mineralization is based on the principles outlined in the book Erica contributed to, The Intelligent Gardener. In the years since the book was published, we have continued to refine our approach. OrganiCalc, our online soil analysis webapp, contains all the latest updates.
Vegetables, fruits and grains are a major source of vital nutrients, but centuries of intensive agriculture have depleted our soils to historic lows. As a result, the broccoli you consume today may have less than half the vitamins and minerals that the equivalent serving would have contained a hundred years ago. The Intelligent Gardener demystifies the process of re-mineralising the soil.

- We don’t sell amendments. We’re not in it to add anything you don’t need to your soil.
- We don’t think perfect mineral balance is all your soil needs. Great soil has excellent soil biology, which depends so much on appropriate moisture, organic matter, soil structure, etc. In some ways the mineral balance is the easy part.
- We don’t think soil biology is enough in all situations. So many of us are growing on marginal land which can be completely lacking one or more elements essential for plant growth. Why not get a soil test and find out what’s missing?
- We don’t stop learning. There is so much to know about how to grow well. We love sharing what we know with all of you.
We all come from here, this planet, this spirit. Our bodies, our bones, our living biome, arose from this beautiful Earth, passed down through all of our ancestors. The awesome mystery of our being arose out of our sacred Mother. Just as we sometimes forget we are sacred beings, we sometimes forget we came from and will return to the Earth.
Our vision is for all of us to remember where we came from.
— to have reverence for our food
— to have reverence for the land
— to have reverence for each other
We can begin by cultivating real health in our soil, in our food and in ourselves.
