Soil conductivity reflects the quantity of plant available nutrients within the soil solution. Oversupply or undersupply of nutrients should be avoided for best results.

This meter can be used for quick conductivity measurement of soil, fertiliser and hydroponic solutions as well as for general water quality testing (e.g. for testing irrigation water suitability). Soil conductivity provides an indication of the mineral content of the soil. When conductivity is too high plant damage may occur (due to dehydration). A low conductivity may indicate a lack of available soil minerals.

OPERATING GUIDE Calibrate the meter according to the instruction manual.

FERTILISER AND IRRIGATION WATER TESTING PROCEDURE Fertiliser solutions and irrigation water samples can be measured directly by dipping the probe into the sample.

SOIL TESTING PROCEDURE Wearing gloves to avoid contamination take samples from 15 – 20 sites within the test area. Sample to a depth of 15 cm. Remove any plant matter from the top of the sample. Combine samples in a clean container and mix thoroughly.

Take a small subsample of the mixed soil and mix one part soil with five parts deionised water. Shake thoroughly for 5 seconds. Allow the contents to sit for 30 minutes. Swirl the solution and then dip the probe into the soil/water solution and wait for a stable reading. The same soil solution can be used for testing pH. The ideal soil conductivity when prepared as a 1:5 solution is 0.1 – 1.0 mS/cm. However, ideal EC values are dependent on soil clay content and crop specific salt tolerance.

Store in a cool, dry place out of direct sunlight.
