A student in the School of the Environment, Sibble is one of only two students to receive NOAA’s first Educational Partnership Program (EPP) Graduate Research and Training Scholarship. This national scholarship program affords him $45,000 to support his participation in extensive research opportunities with NOA
Sibble’s research focuses on yielding information that will help develop optimum practices for the application of fertilizer in agriculture, specifically fertilizer that uses ammonium nitrate, which can be a threat to human health. This threat occurs when plants do not use all of the fertilizer added to soil and as a result some of the nitrate is removed with rainwater runoff and some of the ammonium becomes ammonia. The ammonia leaves the soil as a harmful gas and enters the atmosphere.
