Clay soil is composed of very fine mineral particles and retains water extremely well. It is nutrient-rich but has poor drainage and can become compacted, making it harder for plant roots to grow. However, with proper management, clay soil can be one of the most productive soil types for farming.
Clay soils typically have the following characteristics:
Crop | NPK Requirements (kg/ha) | pH Range |
---|---|---|
Rice | N: 100, P: 50, K: 50 | 6.0 - 7.5 |
Soybean | N: 20, P: 60, K: 40 | 6.0 - 7.5 |
Wheat | N: 120, P: 60, K: 40 | 6.0 - 7.5 |
Cotton | N: 80, P: 40, K: 40 | 6.0 - 7.5 |
Crop | NPK Requirements (kg/ha) | pH Range |

Sunflower | N: 120, P: 60, K: 60 | 6.0 - 7.5 |
Barley | N: 80, P: 40, K: 40 | 6.0 - 7.5 |
