Advanced Horticultural
Soil Testing Labs
soil & water test kits
A complete soil-testing lab, designed to provide the grower, ag-consultant or researcher
with immediate, accurate and economical soil analysis in the field or in the lab
Advanced Soil Lab
• The Advanced Soil Lab for soil analysis offers the finest visual color
matching system available
• Technically advanced reagent systems and unique extraction
procedures based on the Mehlich 1 extraction, provide fast,
simple and extremely accurate soil testing
• Soil nutrients are drawn from the test sample, providing a clear
liquid extract. The addition of an indicator reagent to the clear
extract produces a color reaction in direct proportion to the
nutrient concentration in the test solution

• The developed color is read against permanent, translucent color
standards provided in the Octa-Slide Comparator, the result is a
simple and distinct color match over a broad test range
• Tests for calcium, magnesium and chloride are performed with an
easy-to-use Direct Reading Titrator. Reagent is dispensed into the
soil extract until an endpoint color change is reached, then results
are read directly from the titrator in parts per million
• Measurement of potassium is conducted with a unique turbidity
tube system
• Copper is determined by means of a drop count method
• Humus is measured against a color chart index with five
color standards
• Complete instructions and conversion charts are included for
accurate and economical soil and plant tissue analysis
