Orchids for one, they are epiphytes which derive their nutrients from the nitrogen in the air. Spanish Moss also lives like this. Water plants don't need soil. If you don't consider sand as soil, then succulents and cacti don't need soil, but then it comes down to how you are defining soil. Almost any plant can be grown hydroponically, that is, with water enriched with nutrients.

Why do humans need soil?

Humans need soil for various reasons, including agriculture for growing food, providing essential nutrients for plants, supporting ecosystems, filtering water, and preserving archaeological records. Soil also plays a crucial role in carbon sequestration and regulating the Earth's climate.


How do you explain to a 5 year old child about plants need soil?

Plants need soil to grow because soil provides nutrients, water, and support for their roots. Just like how we need food to grow healthy and strong, plants need soil to stay healthy and grow big and tall. Soil is like a cozy home for plants, where they can get everything they need to live and thrive.


Why does soil need sunlight?

Soil does not require sunlight itself, but the plants growing in the soil do. Sunlight is essential for photosynthesis, the process by which plants convert sunlight into energy for growth and development. Without sunlight, plants cannot produce the energy needed to survive, affecting the health and fertility of the soil.


Does plant grow better in soil or water?

Plants generally grow better in soil compared to water, as soil provides essential nutrients, support, and stability for root growth. While some plants can be grown in water (hydroponics), most plants thrive in soil due to the balance of nutrients and oxygen it can provide.


Why does soil need plants?

Plants help maintain soil health by adding organic matter, improving soil structure, and preventing erosion. They also support soil microbial communities that aid in nutrient cycling and contribute to overall ecosystem health. Additionally, plants can help regulate soil temperature and water dynamics.
