Some did, they happened to have gotten the soil temperature right.

Their mean annual soil temperature is 8 C or higher.

I'll be testing for soil temperature but I might let them go a day or so on the basis of signs.

At soil temperatures of 22C or higher, very little infection occurs.

He tracks the soil temperature in the spring, waiting for it to go above 40 degrees.

The colour of the ground cover and its insulating ability have a strong influence on soil temperature.

At this depth the soil temperature only varies between 8-12 C throughout the year.

Summertime, when soil temperatures are high, is the ideal time to do this.

A soil temperature of about 60 degrees Fahrenheit is ideal for growth.

They have found that root growth continues until soil temperature drops to about 40 degrees.

Soil temperatures cool to about 40 degrees, which is ideal for root growth.

Roots do not stop growing and functioning until the soil temperatures cool down to 40 or 42 degrees.

The optimum soil temperature for good growth ranges from 55 to 70 degrees.

Twice a day its soil temperature is checked with a digital thermometer.

In addition, warmer soil temperatures after fire events lead to greater microbial activity.

The soil temperature is nowhere near 60 degrees yet.

"Once the soil temperature goes over 70, the water evaporates and most plants stop growing.

In addition, plants are especially sensitive to soil temperatures and have very specific ranges that support healthy growth.

The seeds germinate in the fall or winter when the soil temperature is cool.

They can survive freezing soil temperatures for many days.

They prefer soil temperatures of at least 75 degrees and are very sensitive to ultraviolet light.

As might be expected, these worms respond to soil temperature conditions as well.

White mulch reflects heat from the sun effectively reducing soil temperature.

It sheds excess water while keeping the soil temperature warm and dry.

The point is to keep soil temperatures relatively constant, not to keep plants warm.
