Physical problems

Physical problems 

An optimum physical environment of soils is essential for better growth of plants, consequently for better yields. Based on soils physical properties viz., infiltration, bulk density, hydraulic conductivity, porosity (capillary and non capillary, aggregates etc soil physical constraints are identified as below. 

1. Slow permeable soils 

2. Excessively permeable soils 

3. Subsoil hardening 

4. Surface crusting 

5. Fluffy paddy soils 

6. Shallow soils
