Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. The pH scale goes from 0 to 14 with pH 7 as the neutral point.

Soil-Plant Interactions Soil plays a key role in plant growth. Beneficial aspects to plants include providing physical support, water, heat, nutrients, and oxygen (Figure 1).

Since water can evaporate faster than it can be taken up, tension begins to build up in the xylem. Eventually, the plant is under quite severe tension. Studies show that these tensions "pull" water from the soil into the root, ~neufeldhs/bio/lectures/

Water supply not only affects the yield of gardens and field crops, but also controls the distribution of plants over the earth's surface, ranging from deserts and grasslands to rain forests, depending on the amount and seasonal Author: M.B.

In attempting to deal with the whole and rather complex subject in a single volume some topics are of necessity dealt with only briefly, but this does not detract from the stated purpose in providing a book for students and Peter J.
