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.
