Plant Tissue Analysis
Plant tissue analysis is an important diagnostic tool. Measuring nutrients in plant tissue allows you to “ask the plant how it feels” about growing conditions and nutrient availability. There is more to a plant than nutrients. By looking at carbohydrate fractions there is an opportunity to further characterize what a healthy productive plant is.
Plant Tissue Report
Interpretation is everything so we provide DRIS (Diagnosis and Recommendation Integrated System) as well as the industry standard critical level approach. Our soil report adds a colour coded interpretation so you can visualize the limitations in your soil. Wealso offer combined soil and plant tissue reports to improve interpretation of your results.
Plant Tissue – $36.00
Includes: Protein, Fibre, Sugar, Mineral Composition (Corn Only), Nitrogen, Phosphorus, Potassium, Magnesium, Calcium, Sulfur, Sodium, Iron, Aluminum, Manganese, Boron, Copper, Zinc (All Crops)
Plant Tissue Tracker
Plant Tissue Test Like a Pro!
- Track your nutrients through the growing season.
- Tired of flipping between pages? Compare good/poor areas of fields on the same report.
- All data is tracked by Growth Stage to provide a fair comparison between fields planted at different times.

Staygreen Program Details
What is the Staygreen Program?
Staygreen is a season-long soil and plant tissue program that helps you identify what drives performance in your fields. By sampling at key growth stages and comparing results against top-performing acres, we uncover nutrient trends and opportunities that standard soil & plant tissue tests miss.
Understand what separates average from exceptional — and follow the path to higher yield.
How it works:
Step 1: Pick a Spot – Choose a location that represents the most common management zone in your field (soil type, yield, etc.).
Step 2: Schedule Your Site – Call or text us to set up your location and receive your SGID.
Step 3: Collect Samples – Either sample yourself or let us handle the collection and analysis for you!
Available Crops: Corn, Soybeans & Some Edible Bean Varieties (Others by Request)
Custom Sampling Cost Per Site – $500 per Site (Held at 2025 Pricing)
Five in-season sampling visits including collection and complete laboratory analysis plus year end benchmarking report.
Applies to sites within 50 km of Honeyland Ag Services. Travel beyond 50 km subject to distance-based fee.
Per Site What You Receive
1) Complete Soil Sample – All the standard soil info you expect, plus soil texture — NEW FOR 2026: interpreted for your ‘Path to Higher Yield’.
2) Four Plant Tissue – Growth stage sampling at V6, V10, VT, and R3 for corn. Bean samples are collected simultaneously if you grow both crops. NEW FOR 2026: Interpreted for your ‘Path to Higher Yield’.
3) Plant Tissue Tracker Report – Benchmark your nutrient levels against the top 20% of Staygreen sites from previous years, by growth stage and over time.
4) Final Yield Assessment – Based on cobs/plants shelled at the end of the season. Calculated using plant population, nutrient removal, and kernel weight.
5) Environment & Management Data – Includes precipitation, GDU data, and key management details (planting date, tillage, etc.).
6) End of season benchmarking report – Boxplots comparing your site to the overall group and the highest-yielding sites.
Single Field, Two Zones – $850 per Site
Compare performance areas within the same field (High vs. Medium Yield, Good vs. Poor) — Pay for collection just once.
Self-Sampling Program – $242.50 per Site
You collect the samples. We handle the analysis. Includes 1 soil sample, 4 plant tissue samples, and 1 yield assessment plus year end benchmarking report.
Add Ons
Corn V-Stages Sap Nitrate – $15.00/Sample
End of Season Stalk Nitrate – $25.00/Sample
Add-on sap nitrate testing confirms in-season nitrogen availability during rapid growth, while stalk nitrate testing validates whether nitrogen supply matched yield potential at season’s end.
