The R&D tax credit is activity-based, not industry-based. If your operation runs documented variety trials, tests nutrient or amendment regimens, compares irrigation strategies, tunes a lighting recipe, or trials feed programs against measured outcomes, that work may qualify right now. Row crop and specialty crop operations, greenhouse and vertical farms, aquaculture producers, and livestock and dairy operations all qualify when the work meets the four-part test.
Most operations that qualify do not think of their trial work as research. They think of it as figuring out what works on their ground. But if your team is running replicated variety trials, testing nutrient or amendment programs against measured outcomes, comparing irrigation strategies under uncertainty, tuning a lighting or climate recipe, or trialing feed programs to resolve a performance problem, there is a strong chance that work qualifies right now.
The R&D tax credit does not require a dedicated research department or a formal innovation program. If the work involves technical uncertainty and your team evaluates alternatives to resolve it, it qualifies. An agronomy team running a replicated trial to resolve an unexplained yield gap, a greenhouse manager systematically testing lighting recipes against quality outcomes, or a producer trialing alternative feed formulations to solve a conversion problem can all qualify even if the work is simply part of running the operation. The uncertainty is about whether the approach will work, not whether anyone calls it R&D.
The work must aim to develop or improve the functionality, performance, reliability, or quality of a process, technique, formula, or system. Agriculture and livestock companies meet this through developing more effective precision ag platforms, more productive crop traits, more reliable equipment systems, better-performing breeding indices, or more efficient input chemistries. The improvement does not need to succeed. Failed experiments count toward qualifying research expenses.
A livestock genetics company develops a proprietary multi-trait breeding index that integrates heat-tolerance phenotypes with conventional production traits for a target climate region. The first two model architectures fail to maintain predictive accuracy across the geographic range. The third approach achieves target accuracy. All three attempts qualify because the intent throughout was to improve the predictive performance of the genetic evaluation system.
This prong is met by any agriculture or livestock company developing a better technical approach. Geneticists, biostatisticians, animal scientists, agronomists, mechanical and electrical engineers, and formulation chemists all perform work that satisfies this test as part of their standard project scope.
The work must rely on principles of engineering, biology, chemistry, computer science, or related physical sciences. Agriculture and livestock technical work is grounded in these disciplines: plant science, animal science, quantitative genetics, mechanical and electrical engineering, soil and microbial science, and software development all satisfy this prong. Business decisions about which crops to plant, marketing, and commercial negotiations do not. Technical judgment does.
A precision ag company develops a proprietary yield-prediction model that fuses multispectral drone imagery, soil sensor data, and weather observations. The work relies on data science, computer science, agronomy, and remote sensing physics. A livestock genetics company developing a new genomic selection methodology draws on quantitative genetics, biostatistics, and animal physiology. Both satisfy the technological prong without qualification.
The threshold is low for production agriculture work because the scientific foundation is inherent to the discipline. Agronomy, soil science, plant and animal physiology, nutrition, and environmental control all rest on recognized physical and life sciences.
There must be genuine technical uncertainty about whether or how the approach will achieve the required result. Developing a new variable-rate prescription algorithm with uncertain accuracy across diverse soil and crop conditions qualifies. Re-running a proven planting program on a new field using established equipment settings does not. The uncertainty is about the technical capability of the method, not simply about weather or yield variation that is inherently unpredictable.
An autonomous ag equipment company receives a specification to develop a vision-based weed detection and selective spraying system that achieves a defined accuracy threshold across multiple crop and weed species. The engineering team does not know at the outset whether their model architecture, lighting compensation approach, and actuation timing will achieve the required detection accuracy in field conditions. That uncertainty is the qualifying signal.
Uncertainty about whether a proven equipment configuration will work in a new field is operational variability, not technical uncertainty about the method. The distinction matters to the IRS. The credit applies when the engineering or formulation approach itself is uncertain, not just the field conditions.
The work must involve evaluating alternatives to resolve the identified uncertainty. Replicated plot studies, side-by-side treatment comparisons, staged trials across blocks or racks, stocking and feeding trials, and controlled pilot runs of alternative approaches all qualify. Most operations are already doing this as a normal part of the season. The documentation prong is where most claims succeed or fail: the evaluation process must be traceable, not just described after the fact.
A seed company tests three different trait combinations across four soil and climate zones over two growing seasons before commercializing a new hybrid. Each combination is evaluated against defined performance criteria including yield, stand establishment, and disease pressure response. Results are documented in trial reports and compared head-to-head. The systematic evaluation of alternatives is the process of experimentation. The documentation of that process is what makes the credit defensible under examination.
Most operations perform systematic alternative evaluation as a normal part of the growing or production cycle. The gap is rarely the work and almost always the framing: trial records, plot maps, treatment logs, and yield data already exist, but nobody has ever mapped them to the four-part test. aecre builds the documentation layer around records the operation already keeps.

The following operation types are where aecre actively conducts R&D studies. Qualifying activities, primary QRE categories, and key exclusions are specific to each. Select your operation type for the relevant activity profile.
A 2,400-acre specialty vegetable operation in the Central Valley carried an unexplained yield gap across three of its eleven blocks. The blocks shared soil type and irrigation infrastructure with the high-performing ground, and three seasons of tissue and soil sampling had not identified a cause. The operation's agronomy lead designed a replicated trial across the affected blocks comparing four fertility programs against the standard, varying nitrogen source, micronutrient package, and application timing, with each treatment replicated four times in a randomized block layout and a control strip carried in every replication.
The trial ran two full seasons before a combination of split-applied nitrogen and a targeted micronutrient correction closed most of the gap. Along the way the team collected plot-level yield data, tissue tests at four growth stages, and harvest quality grades for every treatment. None of it was labeled research. It was labeled the 2024 fertility trial, and the results lived in a spreadsheet on the agronomist's laptop next to the plot map. That spreadsheet and that plot map were the contemporaneous documentation the credit requires.
A vertical farm running eleven-tier racks in a converted warehouse could not hold consistent quality across rack positions. Top-tier product met spec, but lower tiers produced shorter, paler leaf with measurably lower dry matter, and the operation was culling as much as 18% of the lower-tier harvest. The lighting vendor's recommended recipe assumed uniform conditions the room did not have. The growing team designed a staged trial varying photosynthetic photon flux density, red-to-blue ratio, and photoperiod independently across matched rack positions, holding nutrient solution and climate constant, with quality graded on a defined rubric at harvest.
Fourteen trial cycles over nine months produced a position-adjusted recipe that cut the cull rate below 5% and reduced energy per kilogram in the process. Every cycle was logged: parameter settings, environmental data pulled from the control system, harvest weights, and quality grades. The operation kept these records to run the business, not to support a tax position. They happened to be exactly the record a four-part test analysis requires.
A land-based recirculating aquaculture operation producing steelhead could not move its feed conversion ratio below 1.35 despite running the feed manufacturer's recommended program. Growth was acceptable but margin was not, and dissolved oxygen sag in the late afternoon suggested the problem might sit in the system rather than the feed. The production team ran a structured program across six matched tanks comparing three feeding frequencies and two pellet size progressions, while separately trialing two biofilter media configurations and a modified oxygenation schedule in paired tanks.
The work took eleven months and produced a combined answer: the conversion problem was partly feeding strategy and partly a dissolved oxygen profile that limited intake during peak feeding. The final protocol brought conversion to 1.18. Tank-level feed input, growth sampling, mortality, and continuous water quality data were recorded throughout, because that is how the operation is run. The team described the effort as fixing the FCR problem. Under IRC Section 41 it was a process of experimentation.
A 900-head dairy in the Upper Midwest saw component levels fall below contract thresholds after a forage quality shift, and the standard ration adjustment recommended by the feed supplier did not recover them. Butterfat sat far enough below target to cost meaningfully on every hundredweight shipped. The operation's herd manager and nutritionist designed a pen-level trial comparing four ration strategies, varying fat supplement source, forage particle length, and buffer inclusion, with cows assigned to matched pens by parity and days in milk and each treatment carried for a full 60-day period.
The trial ran across three treatment periods and identified an interaction between particle length and buffer inclusion that neither the supplier's model nor published recommendations had predicted for that forage base. Pen-level intake, milk weights, component tests, and body condition scores were captured throughout. The operation regarded this as ration troubleshooting, which it was. It was also a designed comparison of alternatives against measured outcomes under genuine uncertainty about the result.
