Technically advanced reagent systems and unique extraction procedures based on the Mehlich I 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, and humus is measured against a color chart index with five color standards. The AST outfits also include simplified procedures for screening of nitrates, phosphorus and potassium in plant tissues.

This kit comes in a hard carrying case with foam inserts to organize and protect the measurement components. This kit also includes simplified and complete instructions, a pad of soil analysis report forms, instructions for collecting representative soil samples and a copy of the LaMotte Soil Handbook. This handbook features charts with data on the nutrient needs of various crops. It also contains general test result information to determine actual lime and fertilizer requirements. The user manual has been attached to this page to answer any further questions.
