Land capability classification assigns numbers from I to VIII to rate land based on its suitability for agricultural uses without long-term damage. Class I land has very few limitations and can be cropped every year, while Class II land requires conservation practices and Class III land requires careful crop selection. Land in Classes V through VIII is generally not suitable for row crops due to limitations like slope, wetness, or rockiness, but can be used for pastures, forestry, or wildlife habitat. The system considers factors like soil depth and drainage, slope, erosion susceptibility, and climate.

2. TOPIC :
LAND CAPABILITY
CLASSIFICATION

3. Land
The surface of the earth
not covered with water
Maybe temporarily or
permanently covered with
water
A pond for aquaculture is
considered land

4. Land Capability
Suitability of land for
agricultural uses.
Usage should not cause
damage to the land
although nutrients maybe
removed

5. DEFINITION :
Land capability classification is a system of grouping
soils primarily on the basis of to produce common
cultivated crops and pasture plants without deteriorating
over a long period of time
LAND CAPABILITY CLASSIFICATION

6. Land Capability Classification:
Assigning a
number to land
Eight classes used
I to VIII with I
being the best
arability
Class I to IV can be
cultivated
V to VIII tend to
have high slope or
low and wet

7. CLASSES (CLASSIFICATION ) :
Class I - Very good land
Very few limitations
deep soil and nearly level
can be cropped every year as long as land is taken care
of
Class II - Good land
has deep soil
may require moderate attention to conservation
practices

8. Class III - moderately good land
crops must be more carefully selected
often gently sloping hills
terraces and strip cropping are more often used
Class IV - fairly good land
lowest class cultivated
on hills with more slope than class III
Class V - Unsuited for cultivation
can be used for pasture crops and cattle grazing, hay
crops or tree farming
often used for wildlife or recreation areas

9. Class VI - Not suited for row crops
too much slope
usually damaged by erosion with gullies
can be used for trees, wildlife habitat, and recreation
Class VII - Highly unsuited for
cultivation
has severe limitations
permanent pastures, forestry, wildlife
slope is usually over 12 percent
large rock surfaces and boulders may be found
very little soil present

10. Class VIII
Cannot be used for row crops or other crops often
lowland
covered with water
soil maybe wet or high in clay
aquatic crops maybe grown there
used for waterfowl habitat

12. Subclass e is made up of soils for which the susceptibility to
erosion is
the dominant problem or hazard affecting their use. Erosion
susceptibility and past erosion damage are the major soil factors that
affect soils in this subclass.
Subclass w is made up of soils for which excess water is the
dominant
hazard or limitation affecting their use. Poor soil drainage, wetness,
a
high water table, and overflow are the factors that affect soils in this
subclass.
SUBCLASSES :

13. Subclass s is made up of soils that have soil limitations within the
rooting zone, such as shallowness of the rooting zone, stones, low
moisture-holding capacity, low fertility that is difficult to correct,
and
salinity or sodium content.
Subclass c is made up of soils for which the climate (the
temperature
or lack of moisture) is the major hazard or limitation affecting their
use

14. General Info you need to
know :
Classification is made for agricultural
purposes
3 major categories of soil groupings:
capability unit, capability subclass,
capability class
Arable-means can be used for crops
