Study Notes
Nutrient Absorption in Plants
- Plants absorb mineral salts through their roots, essential for growth and development.
- Water enters root hairs via osmosis, a process driven by water concentration gradients.
- Mineral salts penetrate root hairs through diffusion, facilitating nutrient uptake.
- Water vapor loss from plant parts, primarily leaves, is termed transpiration, crucial for nutrient transport and cooling.
Sources of Plant Nutrients
- Organic fertilizers include decomposed materials like manure, compost, and plant residues (e.g., leaves, cow dung, poultry waste, maize stalks, sunflower, and bean remnants).
Advantages of Organic Fertilizers
- Enriches soil fertility by adding essential nutrients naturally.
- Enhances soil texture, creating air spaces that improve aeration.
- Increases water retention within soil, reducing the need for frequent irrigation.
- Softens soil, making it easier for cultivation and root penetration.
- Encourages beneficial bacterial activity in the soil, promoting a healthy ecosystem.
Disadvantages of Organic Fertilizers
- Potential for nutrient release to be slower compared to synthetic fertilizers, affecting plant growth rates.
- May require larger application volumes, leading to higher labor and transportation costs.
- Risk of introducing pests and diseases if not properly processed or sourced.
