Adapt Overview John McGuire Simplified Technology Services, LLC mcguire9@gmail.com
Future of Precision Technology Adaptive Nutrient Management A process of developing improved management practices for efficient production and resource conservation by use of participatory learning through continuous systematic assessment. NEERA 1002, Coordinating Committee On Adaptive Nutrient Management USDA/NRCS Developing programs (EQIP, CSP) that promote adaptive management and are providing incentive payments to growers who utilize this process.
Data Collection Data Processing Recommendations Data Analysis Adaptive Nutrient Management &Precision Agriculture Data Collection – any task that includes gathering of information about a particular field or portion of a field. Data Processing - any series of steps that collected data must go through before it is ready to be analyzed. Data Analysis - any methodology that derives meaningful results from the collected and processed data. Recommendations - compiling of the collected, processed and analyzed data to determine the best course for future agronomic pursuits.

Interpreting Stalk Samples From a Normal Year Stalk Nitrate Concentration Low – less than 250 ppm Marginal – 250 to 700 ppm Optimal – 700 to 2000 ppm Excess – greater than 2000 ppm
What do these levels mean? • Low – we potentially cannibalized the stalk and gave up yield. • Marginal – N availability was very close to minimal amounts required. • Optimal – high probability that N availability was in range to max profits. • Excess – high probability that N availability exceeded economic rate.
Guided Stalk Sampling • Identify areas of specific soil types in the field • Pick a lush area within that soil type and put in a point to be sampled • Point #4 was generally placed in a bad area of the field • In the field…
