    • COMING PALMTALK CHANGES - PLEASE READ   02/14/2017

      In the coming week (probably beginning this weekend), several major changes will be occurring with PalmTalk. The result will be short periods of complete closure, or of limited viewing (that is, no posting - but viewing still possible). These changes are major and unexpected complications are always a possibility. So, please be patient and bear with us. For those interested, the first phase will be a migration of the entire site to a new more powerful server. After this is completed, a major upgrade to the newest version of the forum software will then be attempted. It is hoped that these improvements, along with some new configurations of various parameters made possible with the new server capabilities, will result in an elimination of some error messages and glitches which have been plaguing various tasks and viewing recently. As with any upgrade there will probably be some new and/or changed features, or ways of viewing and/or using the forum. I anticipate these will be minor, and as always if there is anything confusing or needing explanation, we will set up a topic to discuss them.

What's your soil temperature?

What is your soil temperature?

I came across a few articles on the effects of root development and plant/root growth. I have dense soil which takes a while to heat up and thus root development is slow( especially in the winter), which means my plants grow slower. Having a lighter soil mix allows the sun to heat the soil faster which speed up the process of root/plant development.

This morning the air temp was 41 degrees at my house and my soil temp was 49 degrees. I checked my garden area with lots of new compost at the same time and it was 70 degrees. I've heard that root development stops at around 55-60 degrees (soil temp)

I forgot to add that my soil temp of 49 degrees was not mulched. I also checked my mulched planters and they were at 62 degrees!

That's what I used Steve. I put it all the way in so I could get the deepest temp. I figured it was pretty accurate because it always has the the same temp reading as my thermostat in the house.

Haven't measured the soil temps but I've dug holes in the middle of winter and early morning you can feel the heat coming out. I have measured the water temp of my bore in the middle of winter and it's a fairly constant 28C. Which is good really, for the plants with the irrigation on cool mornings.
