Equipment for Physical - Chemical Analysis (Soils)

SMART 3 Electronic Soil Laboratory - Complete Solution for Soil Analysis

Advanced portable equipment for precise soil nutrient analysis

Portable and electronic laboratories designed for landowners, consultants, and fertilizer specialists who need immediate and economical analyses without compromising precision. These units analyze fifteen soil factors, including critical macronutrients and micronutrients, using the SMART® 3 Colorimeter to obtain readings in ppm or lb/acre without the need for additional calculations. The SCL-12 model includes a pH meter and a dissolved salts meter, which allow quick and accurate measurements of pH and dissolved salt levels in soils and irrigation waters.

Simplified tests allow at least 20 analyses per soil nutrient, using easy-to-prepare soil extracts based on Mehlich I extraction. Additionally, the manual "A Study of Soil Science" is now available for download, offering a detailed reference and further guidance for performing analyses correctly and effectively. These features make the Electronic Soil Labs an invaluable tool for achieving precise and rapid soil analyses in the field.

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 million lb
1 hectare	15-18 cm	2.25 million Kg

ppm	lb/acre	Kg/hectare
0.5	1	1.12
1	2	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.
