Mineral Nutrition — Min Nutri Soil Inducing
| Nutrient | Conditions inducing deficiency |
| N | Excess leaching with heavy rainfall, low organic matter content of soils, burning the crop residue |
| P | Acidic condition, calcareous soils |
| K | Sandy, organic, leached and eroded soils; intensive cropping system without addition of fertilizer |
| Ca | Acidic, Alkali, or sodic soils |
| Mg | Similar to Calcium |
| S | Low organic matter content of soils ; use of N and P fertilizers containing no sulfur, burning the crop residue |
| Fe | Calcareous silt and clays, high organic matter, calcareous soils |
| Zn | Highly leached acidic soils, calcareous soils, high levels of Ca, Mg, and P in the soils |
| Mn | Calcareous silt and clays, high organic matter, Calcareous soil |
| B | Sandy soils, naturally acidic leached soils, alkaline soils with free lime |
| Mo | Highly podzolized soils ; well drained calcareous soils |
