Interactive Summaries of On-Farm Strip Trials: ISOFAST
This online interactive tool is designed to provide individual and aggregated summaries of on-farm trials conducted by farmers working with ISA. On-farm trials include replicated treatments, or strips, that test different products, practices or technologies in Iowa cropping systems. Data available includes the trial description, trial locations, observed weather and results. Users can select or deselect years by checking boxes on the legend.
The fungicide calculator uses data from ISA replicated strip trials to determine the profitability of a fungicide. Users input the current price of soybeans, the cost of application and the amount of rainfall a location experienced March-May and the calculator will predict the likelihood that a fungicide will be profitable.
Within-Field Profitability Assessment
Through profitability mapping, producers can better understand the performance of their operation by pinpointing the strengths and weaknesses of each field. Using yield data, variable and fixed input costs, management information, weather data and commodity prices, farmers can identify which areas are the most and least profitable. Farmers can use this information to optimize profit by identifying alternatives for underperforming areas and maximizing profitable areas.
Estimate Risk of Late-Season Nitrogen Deficiency
Production goals and resource concerns are unique to every farm. Individual farms can benefit from a conservation assessment, which identifies opportunities for improving agricultural production and natural resource management. Many strategies are available to reduce negative impacts on soil and water as well as improving farm productivity.
With clear goals, it is possible to accurately measure improvements, experiment with alternative practices, authenticate conservation successes and understand where new technologies and opportunities fit within defined goals. ISA staff work with individual farmers and landowners to assess each farm for optimum results.

Water Quality Lab
In 2011, ISA began analyzing water samples in its accredited water lab. The lab is certified by the EPA through the Iowa Department of Natural Resources to analyze E. coli, nitrate, nitrite and fluoride under the Safe Drinking Water Act. Ion chromatography is used for the common nutrients of nitrate, nitrite and phosphate as well as fluoride, chloride and sulfate. E. coli bacteria are quantified using the IDEXX Quanti-Tray® most probable number method.
Other tests conducted in the lab as needed include turbidity (a measure of water clarity), alkalinity and hardness as well as ammonia nitrogen. The lab is routinely audited and uses third party proficiency testing to ensure accurate operation.
Tile water sampling results are sent to growers regularly, and stream sample results are summarized and posted annually.
