tilth

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.

tilth

Physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, rate of water infiltration, and drainage. The tilth of a soil can change rapidly, depending on environmental factors such as changes in moisture. The objective of tillage (mechanical manipulation of the soil) is to improve tilth, thereby increasing crop production; in the long term, however, conventional tillage, especially plowing, often has the opposite effect, causing the soil to break down and become compacted.

tilth [tilth]
(geology)
The physical condition of a soil as expressed in terms of fitness for growth of specified plants or crops.
