Study Notes
Macronutrients
- Nitrogen is found in both organic and inorganic forms in plants and combines with C, H, O, and sometimes S to form amino acids, enzymes, nucleic acids, and chlorophyll.
- Nitrogen is predominantly stored in high-molecular-weight proteins.
- Nitrogen accumulates primarily in stems and conductive tissue as nitrate (NO3) form.
Phosphorus
- Phosphorus is a component of enzymes, ATP, RNA, DNA, and phytin.
- Phosphorus is essential for energy transfer reactions and genetic information.
- Phosphorus facilitates accumulation and translocation of carbohydrates.
Potassium
- Potassium maintains water status, cell turgor pressure, and stomatal function.
- Potassium is required for carbohydrate accumulation and translocation.
Calcium
- Calcium maintains cell integrity and membrane permeability.
- Calcium enhances pollen germination, cell division, and elongation.
- Calcium may detoxify heavy metals in plants.
Magnesium
- Magnesium is a component of chlorophyll.
- Magnesium acts as a cofactor in phosphorylation processes.
Sulfur
- Sulfur is involved in protein synthesis.
- Sulfur is present in amino acids, glutathione, coenzyme A, and vitamin B1.
- Sulfur reduces disease incidence in plants.
