Summary
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 .

| 0:05.0 | conversations related to improving our soil's health and our plants health and ultimately our health by the |
| 0:11.3 | cultivation and production of very high quality food. Thank you all for being here for tuning in and for |
| 0:16.2 | listening. I'm here today with Peter Henry from Puerto Rico, who is someone I've been looking forward to chatting with for quite a while. |
| 0:23.6 | Peter, I've heard about the awesome things that you're doing on your operation from our team here at AEA. |
| 0:30.1 | Tell us a bit about your personal journey and story and your farming context and what you have going on. |
| 0:37.3 | Cool. So it's extremely excited have going on. Cool. |
| 0:37.9 | So it's extremely excited to be on the podcast. |
| 0:40.9 | It's kind of surreal hearing the intro. |
| 0:43.9 | Generally, I'm listening to the podcast on our way to drop food off or like pick up products |
| 0:49.5 | and things like that. |
| 0:50.2 | So amazing to be here. |
| 0:53.8 | I guess like super, super high level. I've been more or less full-time |
| 0:59.2 | farming for about six years now, I would say. We've had this form for six years. We purchased it in |
| 1:07.5 | the pandemic. And I've been like really living off of farming for around three |
| 1:14.2 | years now, where it's a full-time job that supports our family and the entire workforce. |
| 1:22.6 | I guess like super quick, I don't come from a farming background. I mean, I grew between the United States, |
| 1:28.7 | Puerto Rico, spent some time in other places like Venezuela, Mexico, Colombia. So I would say |
| 1:34.9 | like farming has always kind of been around me in the sense that in most of those countries, |
| 1:40.7 | and even in the United States, there's always farms, like in Florida, California, |
| 1:44.5 | you always see farming around you. You hear about farmers. You kind of see what they're going through. |
| 1:51.0 | You consume their products. But I never thought that this would be what I do for a living until maybe |
