Results of Our Work
Replicated Strip Trials
The replicated strip trial database contains summaries of individual trials following On-Farm Network protocols. The summaries include essential management information, spatial yield data, and imagery. Scouting, soil and tissue sampling reports are included if available. The interface allows users to query by year, crop, trial type/detail and location. Trial reports have had farmer-identifying information removed.
Stream Water Monitoring
Data collected from rivers and streams is used to prioritize sub-watersheds, develop scientific publications and establish long-term trend analyses. The information also can be used to develop and fine-tune the performance of conservation edge-of-field practices such as bioreactors, saturated buffers and targeted wetlands.
Agriculture’s Clean Water Alliance (ACWA) contracts with ISA to ensure this level of water sampling continues in priority watersheds.
Guided Stalk Sampling
All ISA research teams have been involved in conducting surveys of corn nitrogen status using late-season aerial imagery and corn stalk nitrate tests. When possible, the sampling locations were paired with water monitoring to maximize the benefits to farmers. The results from individual locations are available in the Guided Stalk Sampling Database.
