MANURE IS RICH IN ESSENTIAL ELEMENTS FOR PLANT GROWTH, INCLUDING NITROGEN (N), PHOSPHORUS (P), AND POTASSIUM (K), AND IS OFTEN LAND APPLIED AS AN AGRICULTURAL FERTILIZER. UNFORTUNATELY, MANURE COMPOSITION AND CONSISTENCY CAN VARY SIGNIFICANTLY IN MANURE STORAGES AND DURING MANURE STORAGE EMPTYING RESULTING IN OVER OR UNDER APPLICATION OF NUTRIENTS DURING FIELD APPLICATION. NEAR-INFRARED SPECTROSCOPY (NIRS) HAS BEEN PROPOSED AS A TECHNIQUE TO PREDICT REAL-TIME MANURE COMPOSITION AND SUBSEQUENTLY REDUCE VARIABILITY DURING MANURE APPLICATION. HOWEVER, WHILE NIRS MANURE NUTRIENT SENSING SYSTEMS HAS BEEN EVALUATED IN LABORATORY SETTINGS, LITTLE INFORMATION IS AVAILABLE REGARDING NIRS MANURE SENSING ON-FARM. IN ADDITION, THERE IS NEED FOR MORE INFORMATION TO GUIDE MANURE APPLICATION STAKEHOLDERS, INCLUDING LIVESTOCK PRODUCERS AND CUSTOM MANURE HAULERS, AND REGULATORY AGENCIES REGARDING THE EFFICACY AND BENEFITS REGARDING THE ADOPTION OF NIRS TECHNOLOGY FOR PREDICTION OF MANURE NUTRIENTS ANDREPORTING IN REAL TIME. THIS RESEARCH INTENDS TO PROVIDE CRITICAL AGRICULTURAL RESEARCH AND EXTENSION DATA TO DETERMINE IF NUTRIENT SENSING TECHNOLOGIES CAN REDUCE THE VARIABILITY IN NUTRIENT APPLICATION, REDUCE VARIABILITY IN SOIL NUTRIENT CONCENTRATIONS ACROSS A FIELD, IMPROVE CROP YIELDS, AND IMPROVE EFFECTIVENESS OF SUPPLEMENTAL FERTILIZER APPLICATIONS WHILE MINIMIZING ENVIRONMENTAL IMPACT WHEN COMPARED TO TRADITIONAL APPLICATION METHODS SUCH AS FIXED RATE AND VARIABLE RATE APPLICATORS. ADDITIONALLY, THE PROJECT WILL PROVIDE CRITICALLY NEEDED EXTENSION MATERIAL AND PROGRAMING REGARDING NIRS NUTRIENT SENSING TECHNOLOGY DESIGNED FOR EXTENSION PERSONNEL, REGULATORS, AND AGRICULTURAL STAKEHOLDERS TO USE FOR MAKING RECOMMENDATIONS FOR TECHNOLOGY ADOPTION.
