Soil Moisture Relationship with GeoDrops

GeoDrops Lounge
1

I have read all I can about GeoDrops and moisture measurements. Great reading and I think I understand a lot more now.

My turf management software will let me manually enter soil moisture reading, but they are in VWC percentages.

In the GeoDrops article it shows:

VWC 30% - GeoDrops 100%
VWC 20% - GeoDrops 67%
VWC 10% - GeoDrops 33%
VWC 0% - GeoDrops 0%

Is there a formula, chart, software or something that would show the relationship at any given point between the GeoDrops moisture reading and VWC percentage?

I’m not looking for exact but something close.

Hi @ebelew ,

First, I want to say a huge thank you for your patience and for your continued enthusiasm for GeoDrops. It is really rewarding for us to see a user dive this deep into the data and take the initiative you did with that chart.

Please accept my apologies for the delay in getting back to you. I missed this in the Lounge section as we have been fully focused on the current rollout.

While the team is currently prioritized on the launch, I am flagging your initiative here as a great topic for us to look at more closely once we have more capacity for a technical deep dive.

Thank you again for being such a keen part of the community and for sticking with us.

Best,

Thanks. I think I need to understand this relationship because of the way GeoDrops views moisture content versus the rest of the world. As my GeoDrop sensor is showing 85% my lawn software is asking for a moisture reading but looking for VWC. Because that is the way the rest of the world calculates soil moisture for suggesting when I water and ET for my lawn. Until the rest of the world catches up with GeoDrops, I think, I need to understand this.

I just hope I am looking at this relationship correctly, so I can setup GeoDrops to monitor soil moisture and alert me at 50% and tell my lawn software that is really a VWC of 15%.

Am I comparing these correctly?

Hi @ebelew,

Great technical question. As shown on the roadmap below, a guide for “Raw Moisture vs. Real Moisture” (link) is slated down the road to address how these values correlate.

The team is currently focused on other priorities, so this should provide more context once it is available.
