Hanna Instruments-7051 Soil Sample Preparation Solution is an electrolyte solution used in the measurement of soil pH. The pH of soil is most commonly measured as either a water slurry or electrolyte slurry, where a set ratio of soil:solvent (solvent is water or electrolyte solution is chosen; common ratios used for soil pH are 1:1 1:2 or 1:5, where more solvent than soil is used when soils-to-be-analysed contain high amount so organic matter or clay. Use of an electrolyte solution is usually preferred as it is less affected by soil electrolyte concentration and provides a more consistent measurement for soils whose salt content may fluctuate as a result of seasonal conditions or crop residues.
Using the Hanna Instruments-7051 solution prior to taking a measurement provides for a more accurate pH reading of soil samples.
