| non-mineral | hydrogen (H), oxygen (O), & carbon (C) | |
| mineral | ||
| primary nutrients | nitrogen (N), phosphorus (P), and potassium (K). | usually lacking from the soil as plants use large amounts for growth and survival. |
| secondary nutrients | calcium (Ca), magnesium (Mg), and sulfur (S). | usually enough in the soil |
| micronutrients | boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). | |
| Hormone | Function | Location |
| Auxins (IAA)* | stem elongation root formation | apical dominanace produced in shoot apical meristem |
| Cytokinins | cell division differentiation | produced in roots |
| Gibberellins (GA)* | stem & internode elongation seed germination | produced in apical portion of root & shoot |
| Ethylene* | abscission fruit ripening | produced in leaves, stems & young fruits |
| Abscisic Acid | supression of bud growth stomatal opening leaf senescence | mature leaves, fruits & root caps |
