1. Nutrient supply: Soil provides essential nutrients such as nitrogen, phosphorus, potassium, and other micronutrients that plants need for growth and development.
2. Water supply: Soil acts as a reservoir for water, providing plants with the necessary moisture for photosynthesis and other physiological processes.
3. Anchorage: Soil provides physical support for plant roots, allowing them to anchor themselves securely and absorb water and nutrients from the soil.
4. Oxygen supply: Soil contains air pockets that allow oxygen to reach plant roots, which is essential for respiration and nutrient uptake.
5. Protection: Soil acts as a buffer against extreme temperatures, protects roots from physical damage, and provides a habitat for beneficial soil organisms that help plants grow.
Overall, soil is a crucial component for plant growth and health, providing essential nutrients, water, support, and protection for plants to thrive.
