Study Notes
Mineral Salts in Plants
- Mineral salts are chemical compounds formed when a metal reacts with a non-metal. They dissolve in water, producing ions that carry electrical charges.
Functions of Mineral Salts in Plants
- Photosynthesis: Minerals like nitrogen, phosphorus, and magnesium are essential for chlorophyll production and the photosynthesis process.
- Nutrient Transport: Potassium helps regulate the movement of water, nutrients, and other molecules within the plant.
- Fruit & Flower Development: Phosphorus and boron are important for plant reproduction and fruit/flower development.
- Structural Support: Calcium and silicon provide structural rigidity to plant cell walls and tissues.
Importance of Mineral Salts
- Mineral salts are essential nutrients in soil, contributing significantly to plant fertility and growth.
- They provide crucial elements like nitrogen, phosphorus, and potassium for various plant functions.
- Availability of these minerals depends on soil pH; optimal absorption occurs in optimal pH ranges.
Specific Minerals and Their Roles
-
Nitrogen: Essential for leaf growth and overall plant size.
-
Phosphorus: Important for energy, cell movement, structure and regulating water movement; improves root growth and flowering quality of fruits.
-
Potassium: Regulates water quality of fruits.
Nitrate Deficiency Symptoms
- Yellowing leaves (chlorosis): Most common symptom, due to the role of nitrate in chlorophyll production.
- Stunted growth: Impaired protein synthesis limits cell division and tissue formation.
- Curling leaves: Sign of water stress.
- Reduced productivity: Lower protein levels mean smaller fruits and fewer flowers.
- Overall weak plant appearance: The plant appears unhealthy and unproductive.
