The Above and Below of Soil and Plant Health
Join John Kempf for the above ground half of the day and Michael Phillips for the below ground half of the day to truly advance your knowledge of plant biology, plant nutrient cyles, plant-fungal interactions, soil biological process benefitting crops and much more.
John Kempf-The Principles and Science of Developing Regenerative Agriculture Ecosystems
Essentially all soil and plant ecosystems are substantially degraded, to a point where we don’t immediately recognize how severely they are malfunctioning. We don’t have a frame of reference to know what “normal” actually looks like. It is common for most crops to produce only 15-25% of the yield they are genetically capable of. It is common for many plants to photosynthesize at only 15-25% of their capacity in a 24 hour photo-period.
In this workshop, John will describe the principles and the science of regenerative farming ecosystems that harness much more of the energy coming into the system, and produce Olympic athlete-level performance. We already have the knowledge and information needed to increase soil and crop performance to several times higher than the current system. We simply need to implement what is already known. We can develop regenerative agriculture ecosystems in which soil health is quickly regenerated, crop yields and quality constantly improve, pest pressure becomes less of a challenge and crops are much more resilient to climate extremes. When a truly regenerative ecosystem is functioning well, the need for external inputs becomes less and less. In this discussion attendees will learn:
- The science of soil-plant interactions.
- How to manage nutrition to shift plant hormone balance and reproductive expression, leading to:
- How to increase the number of seed or fruit,
- How to speed up or slow down crop maturity
- How to increase fruit or seed size
- How to increase protein content, oil content, and test weight
- How to prioritize cultural management practices and product applications to produce the greatest ecosystem response.
- How to develop disease suppressive soil by managing crop and cover crop rotations.
- How to monitor a crop’s nutritional integrity through the growing season.
- Why insects and diseases are attracted to crops with specific nutritional profiles, and how to prevent them.

Working with the Soil Food Web to Grow Healthy Crops
Trillions upon trillions of soil organisms make up the Soil Food Web. A vibrant biology is every farmer's dream team, and our most fundamental job as captain (a bold assumption, indeed!) is simply not to screw up our team. Rousing every grower to think deeper begins with appreciation for how soil biology abets healthy plant metabolism. Mycorrhizal fungi distribute nutrients and moisture throughout a plant community by means of fungus-root synergy. The deep nutrition delivered by the common mycorrhizal network in turn makes for productive crops. Soil aggregate formation by the fungi addresses carbon flow. Building regenerative soil is quite frankly a fungal act. What was once referred to as good tilth can be viewed as the physical manifestation of practices that limit tillage and other choices harmful to soil biology. The myriad of bacteria work in collaboration with fungi to fix nitrogen, make locked-up minerals available, and enhance plant energy reserves with partially-built nutrition in the form of bacterial metabolites and growth hormones. Appreciating relevant (read holistic) science side allows us as growers to know many of these organisms up close. Grower intuition and imagination in turn allows us to see a bigger picture. Diversity of plants is key to biological quorum sensing. Interplanting row crops, cover crop cocktails in the fallow season, mob grazing, roots mingling with hedgerows and other wild areas on the farm contribute to this overall harmony. We will also explore what happens when biology arises to crop surfaces in creating an arboreal food web. As below so above, one might say in carrying ancient wisdom to a next level of understanding. Reinforcing biology can be done in conjunction with nutrient sprays. Ultimately, effective stewardship of the land involves keeping the organic matter flowing, as it’s only through actively recirculating carbon that we honor fungal ways and plant wisdom. Tomorrow can be redeemed by honoring this fundamental earth pact. No-till farming lies at the heart of changing American agriculture for the better.
