Land Capability Sub-Classes and their Characteristics Subclass Descriptions: Capability sub-class is the second category in the land capability classification system. It represents the soils physical, chemical or atmospheric limitation due to which the land use is further restricted.
1. 'c Adverse Climate - This subclass denotes a significant adverse climate for crop production as 'median' climate which is defined as one with sufficiently high growing-season temperatures to bring crops to maturity. 2. 'd' Undesirable Soil Structure and/or Low Permeability - This subclass indicates soils that are difficult to tll or soils where water is absorbed very slowly or where the depth of rooting zone is restricted by conditions other thar a high water table or consolidated bedrock.
3. 'e' Erosion - This subclass includes soils where damage from erosion is a limitation to agricultural use. Damage is assessed on the loss of productivity and on the difficulties in farming land with gullies 4. " Low Fertility - This subclass includes soils having low fertility that is either correctable with careful management with the use of fertilizers and soil amendments or is difficult to correct by any practical means. The limitations may be due to lack of plant nutrients, high acidity or alkalinity, low cation exchange capacity, high levels of carbonates or presence of toxic compounds.
5. i' Inundation by Streams or Lakes - This subclass includes soils subjected to inundation causing crop damage or restricting agricultural use. 6. 'm' Moisture Limitations - This subclass consists of soils where crops are affected by drought owing to inherent soil characteristics. These soils usually have low water-holding capacity 7. 'n' Salinity - Soils of this subclass possess excessive soluble salts which adversely affect crop growth or restrict the range of crops that may be grown.
8. 'p' Stoniness - These soils are sufficiently stoney to hinder tillage, planting and harvesting operations, 9. 'r' Consolidated Bedrock - This subclass includes soils where the presence of bedrock near the surface restricts their agricultural use. Consolidated bedrock at depths greater than 90 cm from the surface is not considered as a limitation except on irrigated lands where a greater depth of soil is desirable.
10. s' Two interpretations were accorded to subclass s. In the case of maps generally prepared before 1969, subclass s was used in place of subclasses d, f, m or n. If two or more of subclasses d, f, m or n are applicable to the same area, then again subclass s may be used. On most of the maps prepared after 1969, the applicable subclass d, f, m or rn appear if an area is classified with a single subclass. For areas classified with two or more of the d, f, m or n subclasses, subclass s will appear denoting a combination of subclasses.
