Study Notes
Essential Nutrients
- Macronutrients (required in large amounts):
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
- Calcium (Ca)
- Magnesium (Mg)
- Sulfur (S)
- Micronutrients (required in small amounts):
- Iron (Fe)
- Zinc (Zn)
- Copper (Cu)
- Manganese (Mn)
- Boron (B)
- Molybdenum (Mo)
- Chlorine (Cl)
Modes of Nutrition
- Autotrophic: Plants synthesize their own food through photosynthesis
- Heterotrophic: Plants obtain nutrients by decomposing organic matter
- Mixotrophic: Plants have both autotrophic and heterotrophic modes of nutrition
Nutrient Uptake
- Passive uptake: Through osmosis and diffusion
- Active uptake: Through carrier proteins and energy-dependent transport
Soil Factors Affecting Nutrient Availability
- pH: Affects nutrient solubility and availability
- Temperature: Affects microbial activity and nutrient cycling
- Water: Affects nutrient availability and uptake
Nutrient Deficiency Symptoms
- Nitrogen deficiency: Stunted growth, yellowing of leaves
- Phosphorus deficiency: Stunted growth, dark green leaves
- Potassium deficiency: Weak stems, yellowing of leaves
- Calcium deficiency: Blossom end rot, weak stem growth
Fertilizers and Soil Amendments
- Organic fertilizers: Derived from living organisms (e.g., manure, compost)
- Inorganic fertilizers: Synthetic or mined (e.g., ammonium nitrate, potassium chloride)
- Soil amendments: Additives to improve soil structure and fertility (e.g., lime, gypsum)
