1. |
Quadrat sampling |

A field sampling technique in which small plots, called quadrats, are laid out in the landscape and from which the sample is drawn. |
2. |
Quadrifilar helix antenna |
| |
A type of GPS antenna in which four spiraling elements form the receiving surface of the antenna. For GPS use, quadrifilar antennas are typically half-wavelength or quarter-wavelength size and encased in a plastic cylinder for durability. |
3. |
Quadrille paper |
| |
Ruled paper divided 4, 5, 8, or 10 squares per inch and used for first-draft drawings. |
4. |
Quality circles |
| |
A small group from the work unit, ranging in size from 4 to 15, who voluntarily meet on a regular basis to study quality-control and productivity improvement techniques and to identify and solve work problems. |
5. |
Quartzite |
| |
A compact granular rock composed of quartz crystals, usually so firmly cemented as to make the mass homogenous. The stone is generally quarried in stratified layers, the surfaces of which are unusually smooth. Its crushing and tensile strengths are very high. Example: Quartzite Boulders. |
6. |
Quick test (seed testing). |
| |
A type of test for evaluating seed quality, usually germination, more rapidly than standard laboratory tests. |
7. |
Quicker method (of purity testing). |
| |
The method of purity testing which distinguishes between seed and inert matter purely on the basis of physical characteristics. See 'Stronger method'. |
8. |
Quickly available fertilizer |
| |
A fast-action fertilizer that has its nitrogen in a water-soluble form for immediate release into the soil. |
9. |
Quiescence |
| |
The absence of growth, usually inferring the absence of environmental conditions favoring growth; although dormant seeds are quiescent, quiescence is distinguished from dormancy which implies the inability to germinate even in the presence of environmental conditions favoring growth. |
10. |
Quincunx |
| |
An arrangement of five objects, usually trees, with one at each corner of a rectangle and one at the center; this basic structural unit is often multiplied to create a larger pattern, and plantations of trees in this pattern may be identified by the same term. |
