  1. Using Grid Soil Sampling w/Precision Ag Technologies Katlynn Weathers Soil 4213 April 10, 2013

  2. Introduction • What is precision agriculture? • What makes it so special? • How can grid soil sampling help?

  3. Introduction • Purpose of Soil Sampling (Why) • Determine fertilizer and lime needs • Influence management decisions • Too much fertilizer reduced nutrient use efficiency • Not enough fertilizer will hurt yields

  4. Consider Grid Sampling If… • Previous management • Significantly altered soil nutrient levels • Confined livestock areas • Unknown management practices from previous years • Desire for more information • Smaller fields merged into one

  5. Types of Soil Sampling Grid Composite / Random Zone

  6. Sampling On a Grid Grid Cell Field Border Sample ID #

  7. Sampling w/ In A Grid Center of Grid Center of Grid Sample points W/ in Grid Cell

  8. Soil Test Results

  10. What Happens Next??? • How will you use this information??? • Layering • Prices in Oklahoma • Flat rate per acre (Central OK) $4.50 -$5.50 • VRT per acre (Northern OK) $6.00 - $8.00

  11. Disadvantages • Cost • Time • Not ideal for all locations • Specialized equipment Advantages • More accurate • Layering of data • Nutrients • Has the potential to save money and increase yields*
