OptimIA program analyzes fruitfulness of US vertical farms

As we have heard from many industry speakers and reported in horticultural lighting coverage, global urbanization and population growth will continue to put a strain on food supply. Such wide-scale concerns also breed opportunities for innovative research which will ultimately support technology development that helps improve food supply.

I recently learned of Optimizing Indoor Agriculture (OptimIA), a Specialty Crop Research Initiative (SCRI) supported by the US Department of Agriculture (USDA). The larger objective is to extend the knowledge base regarding controlled environment agriculture (CEA) — often referred to as indoor farming, vertical farming, and indoor agriculture — to support long-term goals of:

• Increasing uptake of CEA practices
• Addressing food supply — quality, quantity, and availability, particularly in areas where food inequities are prevalent
• Bringing sustainable, profitable operations and techniques to CEA growers

The initiative draws from team members across education and commercial horticultural/agricultural organizations: Dr. Greenhouse, Inc.; Michigan State University; Ohio State University; Purdue University; University of Arizona; and the USDA Agricultural Research Service (USDA-ARS). Some of the participants are familiar names from speaking at past LEDs Magazine events, such as Purdue's Cary Mitchell, MSU's Erik Runkle, and Dr. Greenhouse president Nadia Sabeh.

Digging in to the OptimIA website, I saw the project team had posted a fact sheet of research highlights titled "Potential Profitability and Economic Success of Indoor Agriculture in the United States." These highlights were collected in preparation for contributing a chapter to the upcoming book Plant Factory Basics, Applications and Advances. The fact sheet offers a balanced summary regarding challenges to quantification of profitability, benchmarking data, and other factors. Researchers used a Japanese Plant Factory with Artificial Lighting (PFAL) base-case model to perform their analysis of the profitability of US-based vertical farming.

The most interesting points I have included in the infographic above. But this general conclusion from the highlights comes as no surprise, really: "The changes with the most potential to increase profitability are those that focus on enhancing market price for the quality of product delivered, decreasing capital costs, and improving elements of biomass (plant size, density, and type of crop)." You can download the fact sheet from the OptimIA website.

That's where the hands-on research will come in and why we continue to refine the program for HortiCann each year. We continue to pursue experts with scientific findings, case studies, and system developments that can decrease the capital costs of horticultural solid-state lighting (SSL) and AgTech systems and enhance grower operations with solid data and monitoring for buildable results. For example, look to last year's HortiCann presentations on updated research findings on light spectra for various plant characteristics, data-driven automation, and our blog on the grower panel, which centered around end-user experiences in applying LED lighting to greenhouse operations — lessons learned and how they plan to evolve operations with future updates.

Watch the HortiCann Light + Tech website for updates to the program and register to join us for the free virtual event Sept. 28-29, 2021.
