Cole Mannix is a multi-generational rancher from central and western Montana who serves as the founder of Old Salt, a vertically integrated startup enterprise. Coming from a background rooted in mountain grazing and extensive holistic management, Cole spent decades working alongside his family and regional producers to optimize ecological function, riparian health, and predator coexistence on their expansive home landscapes.

Recognizing the vulnerabilities ranching families face as processing and retail channels become increasingly consolidated, Cole launched Old Salt to construct an alternative ecosystem of localized market power. Under his leadership, Old Salt has grown to incorporate a membership of ranches operating alongside processing hubs, a direct e-commerce engine, local restaurants, and an annual community festival hosted directly on his family's ranch. Cole is dedicated to creating experiential, relational marketplaces that adequately reward producers, support active workforce ownership, and increase the sheer volume of passionate hearts and hands managing the landscape.
In this episode, John and Cole discuss:
How Cole engineered an LLC model with cooperative principles to access external capital without risking members' family lands.


Constructing a vertically integrated market to disrupt highly consolidated, downstream corporate meat packing and processing monopolies.


Establishing regional slaughter facilities and custom restaurants to stabilize profit margins and balance animal carcasses locally.


Rerouting financial value directly back upstream to give independent ranchers viable financial alternatives to commodity supply chains.


Why integrating livestock back into modern cropping systems is restricted by structural barriers like missing fences and scarce water infrastructure.


Creating parallel government incentive programs focused on funding active farm labor rather than subsidizing crop insurance yields.

Peter Henry is a first-generation farmer who manages a diverse, seven-hectare operation in the mountainous terrain of Puerto Rico alongside a dedicated four-person workforce. He transitioned to agriculture during the pandemic after a successful career as a tech executive and startup vice president, initially purchasing the abandoned land with the intent of establishing a shade-grown specialty coffee farm. After encountering significant challenges with his initial coffee crops, Peter successfully shifted his operation toward passion fruit and a highly specialized niche market growing traditional African heirloom vegetables and tubers for buyers in the United States and Canada.  

Peter focuses heavily on biological soil health and precise nutritional balance instead of conventional chemical applications. He works closely with Advancing Eco Agriculture (AEA) to run on-farm trials and design sophisticated nutritional programs using AEA's data-driven inputs. By utilizing rigorous soil testing to address extreme iron and manganese imbalances, Peter designs custom foliar stacks delivered through a specialized micro-sprinkler system to proactively build plant immunity and suppress heavy tropical disease pressure.  
In this episode, John and Peter discuss:
How Peter manages a complex landscape by separating the farm into distinct irrigation sectors to address vastly different soil mineral profiles on opposite sides of a river .

Utilizing an aggressive pre-planting soil amendment strategy that combines lime and custom humic-complexed fertilizers based on comprehensive soil tests .

How the operation completely avoids synthetic nitrogen applications because excess nitrogen immediately triggers insect pressure and fungal blights across his pepper and okra crops .

Peter designing an innovative micro-sprinkler trellis system to broadcast humics and biology over multiple hectares in just over an hour .

Mixing AEA's Humacarb, HoloPhos, and Spectrum directly into the irrigation system to actively inoculate both the soil and plant foliage with beneficial microbes .

How running an on-farm trial of AEA's Pinion product for six weeks successfully eliminated severe bacterial leaf spot and stem issues on highly susceptible heirloom bell pepper crops .

Integrating AEA's Rebound Copper alongside Rebound Molybdenum to completely reverse visual deficiencies and provide a dramatic greening effect on the farm's terraced pepper fields .

Utilizing AEA's SeaShield and MacroPak to safely deliver trace organic nitrogen and essential amino acids without overriding the plants' reproductive cycles .

Tom Cotter is a third-generation farmer from Austin in southeast Minnesota who operates a diverse operation alongside his family and brother-in-law, Tony. He began farming with his dad in 1994 under a purely conventional system characterized by full tillage and routine chemical applications. Tom's journey into soil health began unexpectedly when his father purchased a tile plow and they noticed how much easier the equipment pulled—and how much better subsequent yields were—following a 20-acre test planting of rapeseed cover crops.
Today, Tom manages an operation encompassing 340 acres of certified organic ground, 430 acres of conventional no-till ground, and an 80-acre pasture. Driven by a desire to cut input costs and work with nature, Tom has successfully integrated a five-way crop rotation with multi-species cover crop mixes and intensive grass-finished livestock grazing. He is passionate about helping his local community and fellow producers, actively collaborating with the Minnesota Soil Health Coalition to host annual field days and food health days.
In this episode, John and Tom discuss:
A small trial of rapeseed in the 1990s that dramatically improved soil structure, earthworm populations, and subsequent corn yields.

How integrating a 40-way cover crop mix and livestock triggered a massive biological explosion of 25 to 30 earthworms per shovelful.

Balancing organic and conventional no-till acres using a simple plus-and-minus grading system to track soil health trends.

Grazing livestock on crop ground for up to 10 months out of the year to cut feed costs and to act as a natural, variable-rate fertilizer system.

Shifting to an adaptive multi-crop rotation distributed the workload, eliminated grueling hours, and reduced seasonal stress.

How designing smart crop sequences and planting winter rye allowed him to completely eliminate fungicides and insecticides on his conventional acres.

Distributing his workload so that he can take weekends off and enjoy motorcycle rides during harvest season .

In this Podcast Extra, John Kempf joins the Soil Strategies podcast, hosted by Roy Thompson of the South Dakota Soil Health Coalition, to break down a radically different operating system for agriculture that transitions away from traditional NPK mindsets toward biological agronomy .
In this episode they discuss:
How high-salt index, electrolyte-based fertilizers interrupt plant signaling and create a long-term dependency by sabotaging effective microbial colonization .

The powerful role a healthy microbiome plays in supercharging a plant's native genetic expression for ultimate disease and insect resistance .

Why conventional soil tests have historically been utilized primarily as fertilizer sales tools rather than agronomic guides .

The incredible economic opportunity growers have to break away from being "farmed" by input companies by optimizing free resources like water, sunlight, and carbon dioxide .

And how well-designed foliar applications can harness the plant's photosynthetic engine to dramatically increase sugar production and feed soil biology without causing a yield drag .
