Ag Geek Speak

Sarah and Jodi discuss NAIP aerial imagery and why this high-resolution imagery is invaluable for precision agriculture work in the United States. They share workflows for validating zones, aligning layers, and spotting year-over-year patterns while noting timing pitfalls, thanks to NAIP imagery as a background source.
In this episode, we discuss...
• what NAIP is and who collects it
• benefits of high resolution often associated with newer NAIP imagery
• four-band imagery (RGB with NIR) enabling NDVI
• leaf-on timing and when imagery misleads
• state-by-state differences in resolution and frequency
• FSA and CLU uses that ensure strong georeferencing
• practical steps to draw boundaries and validate zones
• aligning offset satellite layers to NAIP
• leveraging multi-year NAIP to confirm stable patterns
• free access and where to get the data

We talk with Matt Krueger about his field-level view of autonomous tillage with a 9R series John Deere tractor, from kit installation to dust-driven safety stops, and how better boundaries and AutoPath boost both uptime and data quality. Matt's story centers on labor flexibility, real costs, and where autonomy should expand next.
In this special hour-long episode we talk:
• autonomy kit details, JDLink Boost connectivity, dual receivers
• autonomy-grade boundaries and safe offsets near obstacles
• dust sensitivity, camera logic, alerts and overrides
• AutoPath benefits for cleaner headlands and data integrity
• remote control of depth, pressure and implement settings
• ROI framed as uptime and labor flexibility, not replacement
• likely next targets for autonomy: sprayers and air seeders
• subscription pricing models and reliability trade-offs
• NDVI plus as applied maps to trace application misses
• skills and fallbacks when GPS degrades or sensors fail

We dig into why low (acidic) soil pH unlocks aluminum toxicity, how that halts root growth, and which crops suffer first. Then we lay out a practical plan to find acidic patches with smarter sampling, NDVI, and grid-the-zone strategies, and point to lime and buffer pH for the fix.
In this episode, we discuss...
• soil pH as chemical control and pH level of 7 is neutral
• aluminum toxicity risk to crops increases below 6.5 pH 
• wheat relatively tolerant, legumes struggle with nodulation 
• stunted roots and thin stands on slopes and sandier spots 
• acidic areas are patchy and do not always follow productivity maps 
• importance of using intensive grids and how 0–3 inch sampling in no-till helps detect acidicity issues
• soil testing: pair pH with buffer pH to set lime rates 
• target NDVI-low areas and grid inside zones 
• variable-rate lime as the remediation path

Welcome back to the second part of our conversation with Preston Sundeen to explore how a two-year ag program prepares students for precision agriculture careers by building real-world skills across hardware, software, GIS, and agronomy. Sundeen's focus is practical confidence: clean data, sound troubleshooting, critical thinking, and learning to ask better questions.
 
We also talk about...
• defining precision ag as practical, cross-disciplinary work
 • balancing agronomy, GIS, hardware and software fundamentals
 • building file discipline, projections and boundary workflows
 • sourcing NAIP, PLSS, and satellite imagery effectively
 • controller setup, CAN bus basics and diagnostics
 • using simulators to teach certain types of controllers
 • as-applied data, JD Operation Center, SMS, and FieldView exposure
 • teaching troubleshooting: manuals, credible videos and tests
 • digital literacy and AI as time-saving tools
 • measuring success by momentum, confidence and community impact
 
 We had an excellent conversation with Preston and we know you'll enjoy it too.

We unpack why soybean leaves turn yellow in patches, thanks to soybean IDC (iron deficiency chlorosis) and how to predict IDC risk for management. We share the exact soil tests that matter, how to read the lab results, and where precision mapping saves money and yield thanks to IDC management.
We also discuss...
• defining iron chlorosis
• why iron-rich soils still cause deficiency
• limits of testing for DTPA iron alone
• three key predictors: pH, EC (salts), and CCE (calcium carbonate equivalent)
• why percent CCE beats a simple fizz rating
• thresholds where CCE raises severe IDC risk
• how residual nitrate can worsen chlorosis
• grid versus zone sampling for better maps
• using maps to place tolerant varieties and inputs
• practical steps to keep beans green
