In this Tiny Bytes, we talk • the dry vs liquid mindset shift • how density changes gallons into pounds • where to find pounds per gallon on fertilizer labels • comparing phosphorus from 10-34-0 an...

We sit down (again) with Kyle Okke of Agile Agronomy and explore how to make variable-rate residual herbicides actually work, from nozzle physics to dual-tank setups, and why agronomy must lead every tech decision.

Additionally... • Limits of conventional pressure-based rate changes • Why droplet size, pattern, and drift control matter • PWM and duty cycle basics • Turn compensatio...

We explore using precision agriculture to variable-rate apply residual herbicides using soil-driven maps to reduce crop injury on sensitive zones while maintaining strong weed control. Kyle Okke joins us to explain why OM, pH, and texture can set the rate and how sprayer mechanics affect success. In this episode, we discuss • Specialty crops that rely on pre-emerge residuals • Resistant weeds driving need for fall residual applications • Soil variability across landscape positions • Reading l...

We unpack why “precision composite soil sampling” isn’t a contradiction and show how GPS-marked points turn an old method into a reliable trend tool. We cover workflows, gear, timing, and when shifting results should push you toward zones. In this episode we discuss • Pre‑GPS composite sampling and its limits • Marking exact GPS points for repeatability • Keeping post‑harvest or spring timing consistent • Tracking year‑over‑year P, K and pH trends • When composites signal a move to zone...

We break down soil orders like a field guide, linking what you see in a soil profile to how soils behave and how to manage them. From prairie-black mollisols to red-dirt ultisols, we share traits, regions, and practical tips growers can use today. • soil taxonomy as a practical framework • mollisols and their dark, organic-rich surface • vertisols with shrink–swell clays and timing risks • spodosols in conifer forests with leached E horizons • alfisols, clay accumulation, and hardpan concern...

Matt Kruger joins us to share the fascinating story of creating the world's largest corn maze spanning 121 acres with over 20 miles of pathways using precision agriculture technology. We explore how advanced planting techniques, boundary files, and ADMS technology transformed a traditional corn maze operation into a record-breaking agricultural attraction. • Valley Corn Maize east of East Grand Forks, MN opens August 23rd through October 19th, celebrating its 10th year of operation • The mai...

GK Technology introduces Surface Shaping and SD Surface (in conjunction with Rust Sales) which offers land managers an innovative approach to field design. Surface Shaping allows for advanced drainage design, giving farmers the ability to design intentional water flow and directionality, above and beyond normal ditching and "land leveling." Kelly Sharpe explains how this new technology preserves valuable topsoil while eliminating problematic water-holding areas through advanced design and pre...

Soil is more than just what we see on the surface, on average consisting of 45% mineral components, 5% organic matter, 25% water, and 25% air, with bulk density measuring how much dry soil weighs per volume. • Bulk density indicates the space available in soil for air and water • Sandy soils counterintuitively have higher bulk density than clay soils • Clay soils typically contain more organic matter which contributes to greater pore spaces • Bulk density increases as you go deeper int...
