[Webinar Replay] A Cotton Farmer’s Take on Biologicals: Practical Insights on Adoption, Economics & Soil Health
Presented by: Larkin Martin | Hosted by: CHONEX
Larkin Martin, a seventh-generation cotton farmer in Alabama, joined CHONEX for a conversation on biologicals, including adoption, economics, and soil health.
Webinar Summary
The agricultural landscape is undergoing a significant transformation with the rise of biological products, but for farmers, navigating this new terrain can be overwhelming. According to Larkin Martin, a cotton farmer from Alabama, the biological market is "confusing" with "so many products making so many claims." This complexity makes it challenging for farmers to determine which products will genuinely benefit their operations from both productivity and economic perspectives.
The biological product space has expanded dramatically in recent years. Organizations like the Mixing Bowl publish annual diagrams to categorize the vast array of options, from mycorrhizal fungi and biopolymers to seaweed extracts and microbial formulations. These diagrams illustrate the overwhelming number of choices farmers face when considering biological solutions.
Despite this complexity, farmers like Martin remain interested in biologicals because they offer potential solutions to critical challenges. For Martin's operation, these challenges include building organic matter in soils with naturally low carbon levels, finding alternatives to chemical products facing resistance or regulatory issues, and meeting supply chain demands for reduced synthetic inputs. These motivators drive adoption when the biologicals can either improve profitability or solve problems in new and better ways than conventional approaches.
When evaluating biological products, farmers employ various validation methods. On-farm trials represent the gold standard, with sophisticated yield mapping and data analysis to determine efficacy. Alternatively, farmers look to trusted neighbors, friends, or university research for validation before making significant investments. The challenge with biologicals, however, is that their effects can be conditional and cumulative rather than immediate. Some products perform best under specific stress conditions or require multiple seasons of application to demonstrate meaningful results.
During the webinar, Martin emphasized that soil health has become a central focus for her operation. Through practices like no-till farming, multi-species cover crops, and strategic use of biologicals, they've increased organic matter from 0.8% to 2.1% in certain fields. This improvement in soil health translates to greater resilience against weather extremes, better water retention, and more stable pH, creating "better factories for whatever crop we plant."
The term "regenerative agriculture" frequently appears alongside discussions of soil health and biologicals, but Martin notes that definitions vary widely. When asked to speak about regenerative farming, she discovered "as many definitions as I wanted to scroll through" in a Google search. This lack of standardization creates confusion, particularly as different certification programs and supply chains establish their own criteria.
New technologies in ag, combined with effective biological products, could help create more resilient and sustainable farming systems while maintaining profitability, which remains the essential foundation of any agricultural innovation.
For farmers interested in exploring biologicals and soil health practices, Martin suggests focusing on farm-specific challenges rather than chasing incentive programs. She advocates for outcome-based rather than checkbox-style government programs, which would reward actual improvements rather than simply implementing specific practices. Most importantly, she emphasizes the need for good record-keeping and baseline measurements to track progress and potentially qualify for future incentives as programs evolve toward outcome-based models.
