3. What do you mean by soil
suitability ?
Soil suitability is the fitness of given
type of land for defined use.
soil suitability analysis is a method of
land evaluation, which measures the
degree of appropriateness of land for a
certain use.
4. Significance of Soil Site Suitability
• To classify and determine the soil profile type with in the
study area .
• Assess the soil suitability classes within the study area.
• Assess the good quality agriculture soil classes with in the
study area .
• Provide preliminary assessment of strategic cropping land
• Assess suitability of top soil for rehabilitation including
identification of unfavourable materials .
• Provide soil management recommendation for top soil.
• The execution and interpretation of basic surveys of climate,
soils, vegetation and others aspects of soil in terms of
requirements of alternative forms of soil use.
• Identifying the most suitable location for specific agriculture
use .
5. Objective
• To understand soil quality under fruit
growing soils.
• To know the soil site suitability for fruit
orchards .
6. Methods of Soil Site Suitability
• Actual limitation method (Sys et al .1971)
• Optimum yield basis ( FAO 1983)
• Storie index (1976)
• Productivity index (Requier et al. 1970)
• Soil irrigability classification (USBR 1953)
• USDA land capability classification(1961)
7. S1 (Highly suitable) Land unit with nil. or up to 5 slight limitation.
S2 (Moderately suitable)
Land units with more than 5 slight limitation
and / or no more than two severe limitation
S3 (Marginally suitable)
Land unit with more than 4 moderate
limitation or/ and no more than two sever
limitations.
N1 (Currently not suitable)
Land unit with more than 2 severe
limitation that can be corrected.
N2 (Unsuitable)
Land units having very severe limitation that
cannot be corrected.
Suitability classes based on limitation
titative land evaluationSuitability class Degree of limitation
8. Suitability classes based on optimum
yield basis (FAO, 1983)
This was based on optimum yield level of
suitability classes as fallows.
• S1 > 80% of optimum yield
• S2 40 to 80% of optimum yield
• S3 20 to 40% of optimum yield
• N <20% of optimum yield
9. Storie method ( Storie 1976)
This method is based on soil characteristics that
govern the land potential utilization and productive
capacity .
SI = A*B*C*X*Y
SI : Storie index
A - General characteristics of soil profile
B - Texture of surface soil
C - Slope
X - Miscellaneous factor
Y - Average annual rainfall
10. Storie index values of suitability class as fallows
• Very poor (10-19)
• Poor (20-39)
• Fair (40-59)
• Good (60-79)
• Excellent (80-100)

39. Conclusion
Pomegranate
The Typic Ustochrept (Inceptisol) soils underlined by loose weathered basalt ( murrum
layer) below 30 cm soil depth were found to be highly suitable (S1) followed by Typic
Ustorthants and Typic Haplusterts for pomegranate production in Maharashtra.
Grape
The Lithic Ustorthent (Entisol) underlined by loose weathered basalt were found highly
suitable (S1) followed by Typic Ustochrepts (Inceptisol) preforming better in terms of
productivity of grape in Maharashtra.
Banana
The Typic Rhodustalfs and Typic Paleustalfs (Alfisol) were moderately suitable (S2)
followed by Vertic Haplustepts (Inceptisol) (S3) for banana in Andhra Pradesh.
Citrus
The Vertic Haplustert (vertisol) was marginally suitable (S3) and calcareous Typic
Haplustepts currently not suitable (N1) for production Citrus production in Nagpur
District.
From above however concluded that specific soil site selection for specific fruits crop
helps to increase the production and profitability of fruits .
