Workability refers to the ease of which the
soil can be physically controlled for the purpose of cultivation.
For example, if tilling or digging the soil produces cloddy or
plate like clumps, the workability is low. From what I already
know, clay soils aren't the best in terms of workability because it
clumps together and is difficult to break up, whilst sandy soils
usually have a much better workability but tend to be poor for
cultivation because of other reasons.
