Therefore, a ready reckoner for quick appraisal of lime requirement for the acidic soils of Sikkim is suggested to raise the pH 5.5 (Patiram 1991).

Which soil is present in Sikkim?
It revealed that soils of Sikkim belong to 3 orders, 7 suborders, 12 great groups and 26 subgroups. It is observed that Inceptisols are dominant (42.84%) followed by Entisols and Mollisols occupying 42.52% and 14.64% respectively.
Is alluvial soil found in Sikkim?
They are of alluvial and collurial origin. This soil occurs on gently sloping to moderately sloping uplifted river terraces and is susceptible for river bank erosion and flooding. Soils of Sikkim are under horticultural crops.
What is the pH of soil for cultivation?
A pH range of 6 to 7 is generally most favorable for plant growth because most plant nutrients are readily available in this range. However, some plants have soil pH require- ments above or below this range. Soils that have a pH below 5.5 generally have a low availability of calcium, magnesium, and phosphorus.
What is the agriculture of Sikkim?
AGRICULTURE IN SIKKIM
| Crop | Production (000′ tones) |
|---|---|
| Maize | 67.97 |
| Finger Millet | 2.55 |
| Barley | 0.45 |
| Buckwheat | 3.35 |
Which type of soil is common in the Sikkim and Himachal Pradesh?
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.
Where red and yellow soil is found?
Features of Red soil and yellow soil.
These soils are found in the large tracts of Western Tamil Nadu, Karnataka, Southern Maharashtra, Chhattisgarh, Telangana, Andhra Pradesh, Odisha and Chhota Nagpur plateau of Jharkhand.
What is yellow soil?
a soil formed under broad-leaved forests in humid subtropical regions, chiefly on parent material fromclayey shales. It has an acid reaction and low humus content, and its yellow color is caused by the presence of ferric hydroxide.
Which type of soil is found in Assam?
alluvial soils
Soil Type:
The soils of Assam can broadly be divided into four main groups, viz. alluvial soils, piedmont soils, hill soils and lateritic soils. The alluvial soils are extensively distributed over the Brahmaputra and Barak plain and are very fertile.
What is pH full form?
The letters pH stand for potential of hydrogen, since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance. The pH scale was devised in 1923 by Danish biochemist Søren Peter Lauritz Sørensen (1868-1969).
What is the pH of soil class 10th?
Most soils have pH values between 3.5 and 10. In higher rainfall areas the natural pH of soils typically ranges from 5 to 7, while in drier areas the range is 6.5 to 9. Soils can be classified according to their pH value: 6.5 to 7.5—neutral.
What is the best pH of soil for plants?
Vegetables, grasses and most ornamentals do best in slightly acidic soils (pH 5.8 to 6.5). Soil pH values above or below these ranges may result in less vigorous growth and nutrient deficiencies. Nutrients for healthy plant growth are divided into three categories: primary, secondary and micronutrients.
Which type of soil is found in Sikkim Class 10?
Soils of Sikkim have been classified into red loam and red and yellow soils. They are generally dark brown in colour on the surface and reddish in sub surface. The depth of the soil varies, being deep in the valleys and shallow on the hills.
Which type of crops are grown in Sikkim?
Among the chief crops grown in Sikkim are:
- Wheat.
- Paddy.
- Maize.
- Barley.
- Buck wheat.
- Cardamom.
- Potatoes.
- Tea, etc.
Which crop is used in Sikkim?
AGRICULTURE IN SIKKIM
| Crop | Area (000′ hectares) |
|---|---|
| Wheat | 0.17 |
| Maize | 38.46 |
| Finger Millet | 2.47 |
| Barley | 0.42 |
Which type of soil is found in Sikkim and Arunachal Pradesh?
The entire northern plains (including parts of Arunachal Pradesh, Assam, Bihar (Almost entirely), Chandigarh, Delhi (Almost entirely), Haryana, Himachal Pradesh, Madhya Pradesh, Punjab, Rajasthan, Uttarakhand, Uttar Pradesh, and West Bengal) are made of alluvial soil.
What is the pH value of soil in Himachal Pradesh?
Soil pH: In Shiwalik hills of Himachal Pradesh the soils under dominant cropping systems were having mean pH values ranging from 6.04 to 6.90 and 6.0 to 6.93 in surface and sub surface soils, respectively (Table 2).
What is the pH of soil in Himachal Pradesh?
Table 2. Important physico-chemical properties of the soils
| Horizon | Clay (%) | pH (1:2.5) |
|---|---|---|
| AC | 6.4 | 5.2 |
| Ap | 9.6 | 5.4 |
| AC1 | 6.8 | 5.6 |
| AC2 | 5.4 | 5.6 |
Is red soil fertile?
The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous. Thus, proper use of fertilizers and irrigation yields high production of cotton, wheat, rice, pulses, millets, tobacco, oil seeds, potatoes, and fruits.
Where do we find black soil?
Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa Plateau, where there is both moderate rainfall and underlying basaltic rock.
Why red soil is acidic in nature?
The soil is acidic because of the following reasons: Red soil is formed by weathering of acid crystalline rocks. The content of essential nutrients like nitrogen, phosphorus and lime is very less in red soils which results in its slightly acidic behaviour.Many other processes like rainfall, fertilizers, acid rain etc.
