If soil gave signs this clear, you could create a nutrient plan for every field you farm.  The truth is soil can tell you what it needs, if you ask the right questions.  ​

The FS System has a long history of P + K variable rate fertilizer application providing more value to farmers.  The specific nature of VRT addresses the challenges of providing optimum fertility on diverse Midwestern soils.

And now, FS is among the first ag suppliers to employ a nitrogen inventory system to track plant-available nitrogen in the soil and offer a complete nitrogen management recommendation. Equipped with data, we apply insights about actual plant-available nutrients and crop growth to develop fertility plans that feed the crop when it needs it most – reducing the risk of loss of your nitrogen investment to unpredictable environmental conditions.  

FS offers the exclusive N-WATCH​™ nitrogen tracking program, the tool that not only asks the right C12990 N Watch DesignTM.jpgquestions, but can analyze the answers to how your nitrogen investment is being used.  

N-WATCH soil samples are taken at key times of the N-cycle and measured for plant-available N concentrations.  Equipped with field-specific data, your FS Crop Specialist applies insights about actual plant-available nutrients and crop growth to develop fertility plans that feed the crop when it needs it most – reducing the risk of loss of your nitrogen investment to unpredictable environmental conditions.

N-WATCH analyzes plant-available nitrogen (PAN) in soil samples taken in the 1st and 2nd foot layers.  The two forms of PAN analyzed are Nitrate N (NO3-N) and Ammonium (NH4-N).
