Nutrient mobility in plants and Nutrients their availability in soil to the plants and its mobility in the plant system as well as their mobility in soil is quite critical. Elements considered highly mobile in plants may not be mobile in soils.
Available forms of nutrients to plants
| Nutrient | Form available to plants |
|---|---|
| Nitrogen | NO3– , NH4+ |
| Phosphorus | H2PO4–, HPO42 – |
| Sulphur | SO42 –, SO32 – |
| Boron | BO33 –, HB4O7– |
| Moybdenum | HMOO4 |
Mobility of nutrient in soil
| Level of mobility | Nutrient |
|---|---|
| Mobile | NO2/ NO3, SO4, BO3, Mn2+, Cl |
| Less mobile | NH4, K+ Ca, Mg, Cu |
| Immobile | H2 PO4 – ,H PO4, Zn 2+ |
Mobility in plant system
| Class of mobility | Nutrients |
|---|---|
| High mobile | N, P, K |
| Moderate mobility | Zn |
| Less mobile | S, Fe, Cu, Mn, Mo & Cl |
| Immobile | Ca& B |
