| buffering capacity |
ability of a soil to maintain (i.e., resist change in) its pH.
|
| bulk density |
mass of soil per unit volume. Often used as a measure of compaction.
|
| buntline hitch |
simple hitch commonly used to attach a line to a piece of hardware.
|
| burl (burr, in British English) |
an abnormal swelling of a tree trunk characterized by swirling wood grain and meristematic tissue. Wood with these structures is prized for woodworking. Contrast with gall.

Contrast with bearing. (2) a device, often made of rubber or plastic, to reduce vibration or wear between mechanical parts. (3) a fitting used to connect plumbing parts of different diameters (such as in spray equipment).
|

| cabling |
installation of steel or synthetic cable in a tree to provide supplemental support to weak branches or crotches.
|
| callus |
undifferentiated tissue formed by the cambium, usually as the result of wounding. Contrast with woundwood.
|
| cambium |
thin layer(s) of meristematic cells that give rise (outward) to the phloem and (inward) to the xylem, increasing stem and root diameter.
|
| canker |
localized diseased area on stems, roots, and branches. Often shrunken and discolored.
|
| canopy |
collective branches and foliage of a tree or group of trees
