- Moderate limitations.
- Conservation practices.
- Limiting factors: Gentle slope, saline condition, inadequate soil depth etc.
- Examples: Deep red soils, black soils.
- Management practices: Strip cropping, contour tillage, rotation.
- Severe limitations.
- Requires conservation.
- Limitations: Steep slope, high erosion hazard, very slow water permeability, restricted root zone, low fertility.
- Examples: Shallow red soil, slightly saline black soil,
- Management practices: Crop rotation, drainage.
- Very severe limitations.
- Choice of crop is very necessary.
- Suitable for occasional cultivation.
- Extensive use of close growing crops.
- Best suitable for pasture.
- Requires very careful management.
- Examples: Shallow soils, saline soils, alkaline soils.

- Arid soils, uneven soils.
Moderate limitations when grazing is considered.
Severe limitations for:
- Wood land.
- Severe limitations for any type of agricultural activity.
- Extremely rough land.
- Restricted for wildlife, watershed protection, sandy beaches, river wash etc.
- Crop management practice according to land and moisture.
- Agronomic and engineering measures.
- There are 8 classes of land.
- First 4 classes are suitable for cultivation.
- Last 4 classes are not suitable for cultivation.
