The document discusses land capability classification (LCC), which classifies land based on its potentialities and limitations for agricultural use. LCC takes into account soil profile characteristics, external land features, and climate factors to assign lands to capability classes. There are two main groups - arable land classes suitable for cultivation, and non-arable land classes where cultivation is limited. The classification aims to properly match land use to its capabilities to prevent degradation. However, LCC has constraints as it does not consider special crops or economic factors, and assumes a moderate management level.

3. Introduction
 Soil-Soil is porous, powdery and unconsolidated outer layer of the earth’s crust which is
formed by weathering of minerals and decomposition of organic substances. Soil is
dynamic, three dimensional (having length, breadth and depth) piece of landscape with a
three phase (solid, liquid and gaseous) system.
 Land-Land is two dimensional body. Land is the solid part of the earth's surface. Our
land is home to many unique plants and animals. The term 'land' includes all physical
elements in the wealth of a nation bestowed by nature; such as climate, environment,
fields, forests, minerals, mountains, lakes, streams, seas, and animals. To use our land
wisely we have to understand soil.
 The solid surface of Earth that is not permanently covered by water.
 Landscape-Landscape is three dimensional structure.
 A landscape is the visible features of an area of land, its landforms, and how they
integrate with natural or man-made features.A landscape includes the physical elements
of geophysically defined landforms such as (ice-capped) mountains, hills, water
bodies such as rivers, lakes, ponds and the sea, living elements of land cover including
indigenous vegetation, human elements including different forms of land use, buildings,
and structures, and transitory elements such as lighting and weather conditions.
Combining both their physical origins and the cultural overlay of human presence, often
created over millennia, landscapes reflect a living synthesis of people and place that is
vital to local and national identity.

4. Capability Vs Suitability
Capability:- Capability is viewed by some as
the inherent capacity of land to perform at a
given level for a general use. and
Suitability:- Suitability as a statement of the
adaptability of a given area for a specific kind
of land use; others see capability as a
classification of land primarily in relation to
degradation hazards (FAO, 1976).

5. Land Capability Classification
(LCC)
• “Land capability classification is an exercise
for interpretative, grouping and grading of
soils according to their potentialities and
limitations. It helps to organize significant soil
factors for conservation (Stallings J. H,
1957).”
• It also gives detailed information regarding the
productivity of different types of land.

6. Why do We Need
Land Capability Classification?
• Land capability classification:-The first requisite to
conservation of land is to fit the crop to the
capabilities of the soil and the water availability.
• Lands are mainly used for agriculture, pastures and
forestry.
• LCC forms the basis of all the watershed
programmes. It was developed by the USDA(United
State Department of Agriculture).
• LCC is based upon the degree or magnitude of
problem/hazard recognized in the land.

7. According to Kalmalkar, R. J. (1950)- Improper
selection of lands for agriculture uses and lack
of management measures in accordance with
its capabilities greatly deteriorate the soils.

8. When to Use Land Capability
Classification?
 Identification of different groups of land
suitable to different types of production and,
 Mapping of broad types of agricultural land
suitability.

9. Criteria
of
Land Capability Classification

10. Criteria/ Factors Influencing Land
Capability Classification
Soil profile
characteristics
External feature of
the land
Climate factors
 Soil texture
 Effective soil
depth
 Permeability and
internal drainage
 Availability of
nutrients
 Soil salinity
 Soil alkalinity, and
 Soil toxicity.
 Water logging
 Slope and erosion
are the factors that
determine land
capability and limit
the land for
particular use only.
 Rainfall
 Temperature and
 Wind velocity are
important
components that
determine land
capability class.

11. LCC Classification
a) Capability class,
b) Capability subclass and
c) Capability unit

12. Capability Class
Broadly, It is classified into two groups:
1)Arable land classes (Cultivable)
2)Non-arable land (Non Cultivable)
• In arable land frequent disturbance of soil
occur e.g. Crop field.
• Forest and plantation are the example of non-
arable land.

13. Arable Land
Class I (Dark green)
➢ Best suitable for all agricultural crops and
free from hazards.
➢ Deep soil depth and high fertility.
➢ Not affected by any appreciable erosion,
wetness , salinity etc.

14. CLASS II (Pale green)
➢ These lands have moderate soil depth, light or
heavy texture, gentle slope and moderate soil
fertility etc.
➢ Suitable for permanent cultivation with some
soil and water conservation practices.
Class III (Yellow)
➢ Various conservation measures like contour
bunding, graded bunding, etc. are recommended.
➢ These lands are suitable for plants, provided that
the plant cover should be maintained.

15. Class IV (Pink)
➢ Suitable only for occasional or limited
cultivation because of unfavourable soil
characteristics, slope, erosion, depth, drainage,
adverse climate etc.
➢ Engineering measures are recommended here.

16. NON-ARABLE LAND
Class V (Blue)
➢ These lands have the potential to become
class I, but due to particular problem/hazard,
they can’t fulfill the characteristics of class I.
Class VI (Orange)
➢ These lands are suitable for horticultural
crops like mango, coffee, guava, cashew nut,
etc.
➢ Grazing should be regulated to preserve the
plant cover.

17. Class VII (Red)
➢ These lands have severe limitations to use for
grazing or forestry.
➢ Generally lands are droughty and swampy,
having very steep slope, rough, stony or very
severely eroded, infested with gullies.
Class VIII (Purple/ Violet)
➢ Lands are very rough, not suitable for wood
land or grazing.

18. LCC Sub-class
The basis of sub class is to recognize the type of
problem/hazard.
The four types of hazards are:-
1. E (erosion)
2. W (water logging)
3. S (soil related hazard)
4. C (climate related hazard)

19. Capability Unit
 The capability unit is a subdivision of the capability
subclasses depending on the management practices.
For example, class IIIs (Soils have severe limitations
that reduce the choice of plants, require special
conservation practices, or both;
 Soil limitations within the rooting zone) could be due
to excess gravel in the root zone or excess salts, i.e.
the codes IIIs1 and IIIs2 could be assigned.
 The capability units are assigned for the individual
applications, but they generally correspond to phases
or soil groups in the national soil survey.

20. Constraints in Applications of the
Land Capability Classification
• One constraint is that it can not deal at all with special
crops, e.g. like cranberries.
• Adaptations of the method to local conditions are often
made in the various applications to better fit the
individual needs.
• The capability classification is an interpretive
classification based on the effects of combinations of
climate and permanent soil characteristics on:
limitations affecting land use, risk of soil damage if
mismanaged, needs for soil management and risk of
crop failure. This opposed to soil classification, which
is based directly on the soil characteristics.

21. • The criteria on the presence of water on the surface or
excess water in the soil, lack of water for adequate
crop production, presence of stones, presence of
soluble salts or exchangeable sodium, or both, or
hazard of overflow are not considered as permanent
limitations to use in the classification where the
removal of these limitations is feasible.
• Within a class there might be different soils but with
the same degree of limitations in soil use for
agricultural purposes or hazards to the soil, when it is
used. If the land unit consists of more than one
capability class the land unit is given the lowest class.
• There is no crop productivity rating, i.e. class IV (see
below) can be more productive than class I, but also
more fragile.

22. Continued…
• Profitability is not determined.
• A single moderately high level of management
is assumed.
• Factors such as distance to market, conditions
of roads and location of fields are not included.

23. Conclusion
• LCC makes easier to classify different types of
land into specific class based on their
potentialities.
• Suitable land utilization
