ABSTRACT:
Detailed soil survey of Hingni village covering 578 ha. in Wardha district of Maharashtra state was carried out on 1:5,000 scale to
assess the nature of soils, their problems and potentials and land use pattern. Five soil series were identified and mapped at phase
level into 33 soil mapping. Soils were taxonomically classified as Lithic Ustorthents, Typic Ustorthents, Typic Haplustepts and
Typic Haplusterts. The soil map was scanned and digitised. The data of digitised soil mapping units were processed through
‘AGROMA’ Geographical Information System (GIS) package to generate different thematic maps. Land capability classes varied
from Class II to Class VI depending upon the increasing limitations for their use, whereas land irrigability classes varied from 2 to
6. Soil-site suitability evaluation was carried out for major crops, viz. cotton, pigeonpea, sorghum, soybean and banana. Deep to
very deep soils (Typic Haplusterts) occurring on nearly level to very gently sloping lands were evaluated as highly suitable for
majority of crops, while moderately deep soils (Typic Haplustepts) on gently sloping lands were evaluated as moderately suitable.
Shallow soils (Typic & Lithic Ustorthents) on escarp slopes and undulating lands were evaluated as marginally suitable or currently
not suitable depending upon the severity of site and soil characteristics vis-a-vis crop requirements. Such information is helpful in
crop planning and other village developmental activities.
INTRODUCTION
Soil is one of the most important natural resources. Its
maintenance in good health is very much needed for meeting
the increasing demand for food, fibre, fodder and fuel. It
assumes greater significance in present situation, wherein the
scope of increasing the area further for cultivation is very
limited. In view of this, the knowledge on our soils in respect of
their extent on a particular landscape and their characteristics in
terms of potentials and constraints are required so that the
precious soil resource may be put to judicious use without
allowing it to degrade further.
Soil survey is the main tool which provides the basic
information regarding the nature of soils, their properties,
problems and potentials by taking into account geology,
physiography and land use pattern of the particular area. This
integrates soil properties with site conditions which form a
basis for land evaluation for rational and sustainable land use
planning.
Hence, a detailed soil survey was undertaken on 1:5,000 scale
with the objective to map the soils of the Hingni village to
assess the land capability and irrigability, and to — evaluate the
soils for their suitability to cultivation of major crops, viz.
cotton, pigeonpea, sorghum, soybean and banana cultivation. It
provides information about the soils and their characteristics
and potential for better use and management including
agriculture and other allied aspects. The data have been
interpreted as per capability of soils and their suitability for
different crops, which could form the basis for sustainable
agricultural practices and protection of soil resource from being
degraded. The maps and database will be of immense use in
setting up developmental activities and extension work to
achieve rehabilitation of inmates and as a teaching and training
256
tool for farm level workers. Such information will help the user
agencies in understanding the soil potential for different
crops/cropping sequences towards increasing crop production
to reach to a level of self sufficiency.
Study Area:
The Hingni village covering an area of 578 ha. is located at 21°
54' 30" N latitudes and 73° 43' 20" E longitudes in Selu tehsil of
Wardha district in Maharashtra state. The Physiography of the
area consists of steeply sloping to moderately sloping
escarpments, gently sloping foot-hill slopes, undulating uplands
and gently to very gently sloping plains. The nearly level land
surrounded by the eroded basaltic hills is the typical relief
feature in the study area. The geology of the area is essentially
basalt of the Deccan Trap belonging to the Upper Cretaceous -
Eocene period. The major area of the village is covered by
basaltic alluvium. The climate of the area is tropical dry
subhumid with well expressed summer (March to May), rainy
(June to October) and mild-winter season (November to
February). The mean annual rainfall of the area is 934 mm.
METHODOLOGY
Soil Survey Techniques:
Detailed soil survey of Hingni village was carried out on
1:5,000 scale using cadastral base map. The procedure given in
the Soil Survey Manual (Soil Survey Division Staff, 1995) was
followed for delineating the soil units. Soils occurring on
different landforms were studied for morphological properties
and were mapped as phases of soil series. Auger bores were
also taken at frequent intervals to confirm the soil boundary for
differentiating soil characteristics and to study the extent of soil
