The Iowa Nutrient Research & Education Council (INREC), in partnership with IDALS, is expanding its free fall nitrogen soil sampling project to farmers and landowners across 26 counties, including Tama County. The expansion gives more producers an opportunity to get valuable information about nitrogen remaining in their soil after the growing season, at no cost.
Fall sampling can help farmers better understand what is happening in their fields from year to year while building a stronger base of data for nitrogen management. It can also:
🌽 Establish a baseline of residual nitrogen in your fields.
🌽 Build field-level history to help inform future nitrogen decisions.
🌽 Provide valuable data at no cost while contributing to broader research on nitrogen management.
Sampling will follow a consistent, standardized approach, with participants receiving valuable information about their fields. The data will also support research with Iowa State University and tools such as N-FACT, with all shared data remaining anonymous. https://iowanrec.org/ https://n-fact.ag/start
If your farm is in one of these counties, sign up for free fall nitrogen soil sampling and help build a better picture of nitrogen in Iowa soils.
"How much nitrogen should I really be applying?" It's a question farmers ask themselves every day, and we have a tool that can help.
N-FACT provides a way to calculate fertilizer needs for your fields anytime, anywhere in Iowa. Plus, it's completely free.
