Study Notes
Essential Nutrients
- 17 essential nutrients required by plants for growth and development
- Classified into two groups: macronutrients and micronutrients
Macronutrients (6)
- Nitrogen (N)
- Important for amino acid synthesis and protein formation
- Deficiency: stunted growth, yellowing leaves
- Phosphorus (P)
- Involved in energy metabolism, root development, and flower/fruit formation
- Deficiency: stunted growth, dark green leaves
- Potassium (K)
- Helps with overall plant health, resistance to disease, and water balance
- Deficiency: weak stems, yellowing leaves
- Calcium (Ca)
- Crucial for cell wall development and root growth
- Deficiency: blossom-end rot in fruits
- Magnesium (Mg)
- Involved in photosynthesis, cell wall development, and protein synthesis
- Deficiency: yellowing leaves, stunted growth
- Sulfur (S)
- Important for protein synthesis and enzyme function
- Deficiency: yellowing leaves, stunted growth
Micronutrients (8)
- Boron (B)
- Involved in cell wall development, sugar metabolism, and flower/fruit formation
- Deficiency: distorted leaves, brittle stems
- Copper (Cu)
- Important for enzyme function, protein synthesis, and defense against disease
- Deficiency: distorted leaves, dieback of shoots
- Iron (Fe)
- Crucial for photosynthesis, respiration, and enzyme function
- Deficiency: yellowing leaves, stunted growth
- Manganese (Mn)
- Involved in photosynthesis, enzyme function, and disease resistance
- Deficiency: yellowing leaves, stunted growth
- Molybdenum (Mo)
- Important for nitrogen fixation, protein synthesis, and disease resistance
- Deficiency: yellowing leaves, stunted growth
- Zinc (Zn)
- Crucial for enzyme function, protein synthesis, and growth regulation
- Deficiency: stunted growth, distorted leaves
- Chlorine (Cl)
- Involved in photosynthesis, water balance, and disease resistance
- Deficiency: wilting, stunted growth
- Nickel (Ni)
- Important for enzyme function, nitrogen metabolism, and disease resistance
- Deficiency: stunted growth, distorted leaves
Nutrient Uptake and Transport
- Plants absorb nutrients from the soil through their roots
- Nutrients are transported to the xylem, where they are carried to the leaves
- Nutrients are also stored in plant tissues and organs for later use
