A ‘snapshot in time'

Plant tissue analysis offers a precise measurement of the nutritional status of a plant at the time the sample was taken. When tissue testing is used in conjunction with a soil analysis, it can provide information on what nutrient levels are most critical and how best to correct them.

The value of tissue testing

  • Indicates the nutritional status of plants
  • Identifies deficiencies and toxicities before the plant exhibits physical symptoms
  • Offers information important for adjusting and fine-tuning product applications
  • Ability to troubleshoot specific problem areas

Sampling Guide

Plant tissue analysis can be performed on leaf samples and should be a routine part of a good nutrient management program. Remember, an accurate plant analysis relies on proper sample collection.

Example Reports

AgSource Harris offers two plant tissue reports. The standard report graphs test levels as low, optimum or high. One sample is displayed per report page. The summary report charts test results over time, allowing you to monitor nutrient uptake throughout the season. The summary report uses line graphs for easy side-by-side comparisons. Click on the example reports below to see the different options.

PLANT-TISSUE SAMPLING INSTRUCTIONS 
STEPS FOR COLLECTING AND SHIPPING:
  • Plant part to sample: Leaf Blade

      Most turf samples are collected from mower clippings. Keep in mind that soil and fertilizer material can also be picked up by the mower and contaminating the sample. For best results wait at least 2 weeks (if possible) from the last top dress application (fertilizer, fungicide or sand top dress).

  • Samples should be collected on actively growing turf. Do not sample drought or severely diseased areas.
  • If growth patterns (yellow to lighter green color) are apparent, sample separately from "normal" growing areas.
  • Collect approximately one cup of fresh clippings.
  • Because of the moist nature of turf clippings, molding and degradation is a concern, samples should be shipped in paper or cloth bags and loosely packed in the shipping box. If possible let samples dry over night to remove excess moisture. DO NOT ship in plastic containers.
  • Complete laboratory paper work including: client name, turf type, sample identification and any special problems.
  • Ship samples to laboratory as soon as possible. If over night drying is not possible, samples should be shipped by express delivery.
