Soil Moisture Probe Readings
*Do not use these as target numbers for your soil.* There is not an ideal number for everyone to target, this is just provided to show a representation. Seeing how the numbers change can help allow a grower to dial in the “ideal” or “target” numbers for their own particular soil type.
About the Set-up:
Three sensors were placed at different areas around the indoor plant to provide some data on soil moisture. The indoor plant was selected since there would be no added rain water to alter the results all water is controlled via the drip irrigation system installed.
One important factor is to ensure the soil probes are all buried at the same depth and in the same orientation. Then allow them to sit for about 1-2 weeks before collecting data to get more consistent results. Placement of each sensor in relation to the pumpkin plant is provided in the below image but the goal was to get an idea of the three main areas of the pumpkin plant.
Sensor A always seemed to read lower (data is two more posts down) so this could be due to its exact placement and particular soil conditions. This is an important note so a growers does not force the numbers to match resulting in more harm than good by over watering just so the soil meters all read the same.
For the soil conditions the target range was 22%-24%. This range was decided on by digging in the soil (away from the sensors) and actually feeling the soil to determine when the “ideal” soil moisture was reached and THEN checking the probe readings.
