Soils of Himachal Pradesh

Soils of Himachal Pradesh

Himachal Pradesh is situated in the north-western part of Himalaya.
Most of the geographical area of the state comes under forest, pasture, and grazing land; agriculture is possible only on less than ten percent of the state’s net area.
The physiography and climatic condition in the state favours diversified potential for farming and allied activities.
Due to the undulating terrain condition ranging from plains to high hills, Mixed Farming is predominant.
Most of the farming activities are concentrated along the channels of major rivers and their tributaries.
The state has been divided into four agro-ecological zones based on Precipitation, altitude, and Irrigation.
Each agro-ecological zone has its distinct climatic and Soil conditions.
Different types of climatic conditions result into varied Cropping patterns.
Monsoon season in Himachal Pradesh receives more than 70 % of its total rainfall.
Therefore, for the rest of the year, there is water shortage and agriculture requires irrigation. Zone II supports most of the agricultural activities, since rainfall and irrigation are highest in this zone while; they are lowest in Zone IV.

Soils of Himachal Pradesh

The soils found in the Himalayas are diverse in character depending upon altitude, vegetation cover, slope, structure and stage.
The major soil groups in the Himalayas are brown hill soil, sub-mountain soils, mountain meadow soil and red loamy soils, apart from other less major types.
Most of the soils in this region are acidic in nature.
Acidic soils are found in high altitude areas of the western Himalayas, at mid and high altitude regions of the central Himalayas and across all altitudinal ranges in the eastern Himalayas.

Himalayan foothill/terai Soils of Himachal Pradesh:

This type of soil is found in the sub-mountain and foothill tracts of the Himalayas ranging from the western regions in Jammu and Kashmir to the eastern most stretches in Arunachal Pradesh.
While this soil type is extensively found in the foothills of Himachal Pradesh, it is only present in a narrow zone in Uttarakhand from Dehradun to Deori.
This soil has a high content of organic matter and nitrogenous compounds, but lacks phosphate compounds.
The soil is also found in the foothills of Darjeeling, where it has been transported by hilly rivers and streams at altitudes as high as 1500 m.
Here, this soil is acidic and poor in plant nutrients and is made up of sandy material and raw humus.

Forest Soils of Himachal Pradesh:

This soil category is found across the Himalayas under coniferous and deciduous forests in the lower Siwalik range.
This soil type is formed either under conditions of high acidic content (where there is acidic humus) or under mildly acidic conditions.
The top soil of the Soil Profile is very rich in humic matter formed by twigs, bark, leaves and needles.
An important variety of forest soil is brown forest soil, which occurs under dense deciduous forests.
Organic debris from the dense canopy contributes to the topsoil in the form of a thick layer of humus.
This soil can be classified into mildly acidic with high base content and acidic with low base content.

Podzols:

Podzols are found in the western Himalayas and in few areas in Nepal, Sikkim and Arunachal Pradesh.
They are a class of infertile acidic soils that develop under coniferous forests in humid temperate conditions, where the rate of precipitation exceeds the rate of Evaporation.
A continuous percolation of water causes leaching of Minerals like iron and alumina from upper layers, resulting in the formation of a grey bleached zone on the upper surface.
This makes the layer look like ash, giving the underlying soil its name: podzol (pod=under, zola=ash in Russian).
The lack of nutrients and acidic nature of podzols make them poor agricultural soils.
The percolated minerals often form an impermeable layer at the lower end of the soil profile, which restricts water drainage.
These soils occur in high altitude areas near snowline areas.
The parent rock over which it develops varies from quartzite to granite, schist and gneissic rocks.
The depth of the soil ranges from a few centimeters to a meter.
However, sesquioxides or iron oxides usually found in podzols are generally absent in the podzolic soils of the Himalayas. Podzols found in the Himalayas can be divided into two groups: iron podzols (common in Garhwal-Kumaon) and humic podzols.

Red and black Soils of Himachal Pradesh:

These soils are found in isolated areas in Nepal, Bhutan, Uttarakhand (Garhwal region) and Himachal Pradesh.
These are formed from acid and basic Igneous Rocks like granite and basalt.
They are further grouped into red soil dominant type, which is lime deficient, carbonate free and Light textured and black soil dominant type which is comparatively less clayey and deficient in lime.
Red and black soils are deficient in nutrients like phosphate, nitrogen, lime and humus. Their depths vary from 1-70 cm and may be light to dark brown in colour.
These soils support coniferous and mixed deciduous forests of Pinus and Quercus species as well as scrublands.

Desert (arid) Soils of Himachal Pradesh:

These soils are found in the cold desert areas of Ladakh (Jammu and Kashmir), Lahaul, Spiti, Kinnaur and Bharmour (Himachal Pradesh) and pockets of northern Uttaranchal and Sikkim.
These regions have a unique physical, biological, hydrological and anthropological setting that is markedly different from that of the adjoining regions.
These soils are sandy to loamy in texture with clay content of less than 15%. Desert soils are pale brown to yellowish brown in colour and are infertile, lacking nutrients like nitrogen, phosphorous, potassium, sulfur and zinc.

Mountain and hill Soils of Himachal Pradesh:

It is a collective name given to a number of Soil Types occurring at very high altitude areas under sub-tropical and temperate conditions under a wide variety of forests.
These soils have been termed as dabar soils in some parts of Garhwal-Kumaon. Mountain and hill soils are very thin, fertile and may be less than a centimeter deep on steep slopes.
These may occur at elevations above 2750 m in the western Himalayas, over 2500 m in Nepal and over 2400 m in the eastern Himalayas.
These soils are mixed with pebbles and gravel in many regions.
The texture varies from sandy to sandy loam.
The soil reaction varies from acidic to neutral and the organic matter content of these soils ranges from 1 to 5 percent.

High altitude meadow Soils of Himachal Pradesh:

This soil type is found in high altitude meadows found near the snowline in all parts of the higher and trans Himalayas.
Negligible rainfall occurs in these areas and the main form of precipitation is snow.
The soil found here is very thin and fragile.
Since the texture of the soil is very coarse with high gravel content, they are prone to displacement due to slides and avalanches.
These soils are dark in colour and have a high content of humus.

Other different Soils of Himachal Pradesh

Apart from the above-mentioned soils, traces of alluvial soil are found in parts of Uttarakhand and lateritic soils are found in some parts of Arunachal Pradesh.
Erosion due to wind and water is a common problem in the Himalayan belt, especially on steep slopes.
In recent times, several anthropogenic factors like indiscriminate grazing and deforestation has negatively affected the quality of Himalayan soils.

Crops In Himachal Pradesh

Different varieties of crops are being cultivated in the state. Among the Cereals, wheat, rice, maize, and barley are important.
The state also produces pulses and oilseeds. Cash Crops are also becoming important, since fair amounts of potato, ginger, tea, and peas come from the state.
Fruits, dry fruits, and a variety of vegetables are grown in the state.
In addition, there is cultivation of medicinal Plants and herbs, which is also being promoted by the government. Cropping Intensity of the state is over 175 %.

The soils of Himachal Pradesh can be broadly classified into the following categories:

Alluvial soils: These are found in the valleys of the rivers and streams. They are fertile and well-drained. Alluvial soils are formed by the deposition of sediments from rivers and streams. They are typically rich in nutrients and organic matter, making them ideal for agriculture. Alluvial soils are found in the plains of Himachal Pradesh, as well as in the valleys of the major rivers.
Black soils: These are found in the sub-Himalayan tract. They are rich in organic matter and are suitable for growing crops like rice, sugarcane, and maize. Black soils are also known as regur soils. They are formed by the weathering of basalt rocks. Black soils are rich in iron and aluminum oxides, which give them their characteristic black color. They are also rich in organic matter, making them ideal for agriculture. Black soils are found in the sub-Himalayan tract of Himachal Pradesh, as well as in the states of Uttar Pradesh, Madhya Pradesh, and Rajasthan.
Red soils: These are found in the higher hills. They are poor in nutrients and are not very suitable for agriculture. Red soils are also known as lateritic soils. They are formed by the weathering of igneous rocks. Red soils are poor in nutrients and organic matter, making them unsuitable for agriculture. However, they are used for growing crops like maize, millet, and pulses. Red soils are found in the higher hills of Himachal Pradesh, as well as in the states of Andhra Pradesh, Karnataka, and Tamil Nadu.
Laterite soils: These are found in the eastern part of the state. They are rich in iron and aluminum and are not very suitable for agriculture. Laterite soils are formed by the weathering of igneous rocks in a tropical Climate. Laterite soils are rich in iron and aluminum oxides, which give them their characteristic red color. They are also poor in nutrients and organic matter, making them unsuitable for agriculture. However, they are used for growing crops like coffee, tea, and rubber. Laterite soils are found in the eastern part of Himachal Pradesh, as well as in the states of Odisha, Jharkhand, and Chhattisgarh.
Forest soils: These are found in the forests. They are poor in nutrients and are not very suitable for agriculture. Forest soils are formed by the decomposition of plant matter in the forest. Forest soils are typically poor in nutrients and organic matter, making them unsuitable for agriculture. However, they are important for the Growth of trees and other plants. Forest soils are found in the forests of Himachal Pradesh, as well as in the forests of other states in India.
Mountain soils: These are found in the Mountains. They are poor in nutrients and are not very suitable for agriculture. Mountain soils are formed by the weathering of rocks in the mountains. Mountain soils are typically poor in nutrients and organic matter, making them unsuitable for agriculture. However, they are important for the growth of trees and other plants. Mountain soils are found in the mountains of Himachal Pradesh, as well as in the mountains of other states in India.
