SMART 3 Electronic Soil Lab

Order Code: 1985-05

1985-05 200x200The LaMotte Model SCL-12 is designed to provide the landowner, consultant, or fertilizer specialist with a method for achieving immediateand economical soil analyses in the field without sacrificing accuracy.

The Model SCL-12 is a self-contained, electronic soil analysislaboratory that provides accurate answers anywhere for fifteen soil factors, including available forms of macronutrients and criticalmicronutrients. The SMART 3 Colorimeter instantly analyzes color reactions developed in nutrient tests. Display readings are multiplied bya conversion factor specific to each test to provide a result in parts per million (ppm) or pounds per acre (lb/acre)—no further calculationsare necessary. The simplified test procedures provide at least 20 tests for each soil nutrient.

Each accurately standardized system isfurnished in an individual plastic module for quick distinction. All tests are performed in minutes on easy-to-prepare soil extracts, basedon Mehlich I extraction. Critical soil pH measurements are performed quickly and reliably with a battery-powered pH 5 meter. The metermeasures the pH of a one-to-one solution of soil and distilled water over the range of 0-14 pH units to a sensitivity of ±0.01 pH. Soluble Saltlevels in soils and irrigation waters are monitored accurately with a TDS 6 meter, measuring Dissolved Salts from 0-999+ ppm.

Unit Conversion Factors

Unit Conversion Factors

Results can be measured using a choice of units, explained here. Parts per million (ppm), pounds/acre, and Kg/hectare units can be converted to each other using these values:

Area Soil Depth Soil Weight
1 acre 6-7 inches 2 mil lbs.
1 hectare 15-18 cm 2.25 mil Kg
ppm lb/Acre Kg/Hectare
0.5 1 1.12
1.0 2.0 2.24
0.89 1.78 1

A number of variables must be considered when interpreting soil test results in addition to the values obtained. These variables include the composition of the soil, drainage, climate, previous fertilizer programs, and the type of plant to be grown. Samples must also be truly representative of the area being studied and must be carefully selected.
