  2. 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.

  3. 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.

  4. Example of Adaptive Management?

  5. Stalk Sampling Methods & Data

  6. 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

  7. 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.

  8. 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…

  9. Stalk Sampling

  10. Guided Stalk Sampling • Corn following beans • 245 lbs/ac N

  11. Identify Soil Type and Use Image to Pick Points Stalk NO3 Result Guidelines Low (<250 ppm) Marginal (250-700 ppm) Optimum (700-2000 ppm) High (>2000 ppm) Points 1-3 in predominant soil types and good vegetation. Point 4 in a bad area seen from the image.

  12. Stalk NO3 Result Guidelines Low (<250 ppm) Marginal (250-700 ppm) Optimum (700-2000 ppm) High (>2000 ppm)

  13. Strip Trials

  14. Typical Layout and Results

  15. Indiana Field No Manure Corn on Corn Zone of Max. Efficiency Economic Optimum is 175 lb/ac $4/bu $0.50/lb N Optimal

  16. Indiana Field No Manure Corn on Wheat Zone of Max. Efficiency Optimal

  17. Zone of Max. Efficiency Luxury Consumption N-Left Over in Plant Optimal
