1.   Soil temperature was not controlled in our study, and so the evidence linking temperature and root mortality is circumstantial.

2.   Students plotted soil temperatures on a graph throughout the school year.

3.   The Ministry of Agriculture in Britain has developed a forecasting system based primarily on soil temperature in the early spring which can predict the likely severity of nematodiriasis.

4.   A good layer of organic mulch will help modify soil temperatures and moisture.

5.   Abrupt changes in soil temperature can actually heave plants out of the ground, exposing their crown and roots to the drying effects of winter winds.

6.   Cut-up Christmas tree boughs allow air to circulate but moderate the speed of change in soil temperature by keeping the ground in shadow.

7.   Even if you grow your plumerias in containers, mulch to minimize loss of soil moisture and to keep soil temperatures down.

8.   For the soil temperature to rise quickly, the ground must be fairly dry, he said.

9.   Mulch maintains an even soil temperature, conserves moisture and prevents weeds.

10.   Mulch helps preserve soil moisture and helps moderate soil temperature in summer and winter.
