Impact of Fertilizer Application on Soil Nutrients: A 5-Year Study of N-Rich Strips

This presentation discusses a study conducted during the 2010 NUE Conference, focusing on the application of 225 lbs of urea in an N-rich strip and its effects on soil nutrients over five years. Soil tests conducted in March 2010 showed no significant nutrient changes except for one. Utilizing Green Seeker technology, the study analyzed its impact across 50 fields. Over five years, 80 hours of labor resulted in a substantial savings of $384,000 in fertilizer and application costs, highlighting efficiency in nutrient management practices.
