Marine plants do not need soil.
Lichens can grow on rocks where there is no soil. However, they are slow-growing. Most land-based plants do need soil, however.
Plants which normally grow in soil can be successfully grown hydroponically (in water only). This is achieved by providing nutrients (fertilizers) and air to the water which meet the nutritional needs of plants being grown.

∙ 16y agoNo. Many plants can be grown in soilless environments as long as the nutritional needs are met. spagnum or peat moss can be used. Shredded paper and sawdust can also be used. Hydroponics is the science of growing plants in nothing but water with nutrients added. Soil is the best medium for most plants because of the needed bacteria that resides in soil and allows nitrogen exchange to take place into the roots.

∙ 15y ago[1] If plants were people, they'd be feeding through their feet. For it's plant roots that take in the nutrients and water that's sent throughout the above-ground plant parts. [2] They need access to air, nutrients such as minerals, and water. [3] They need protection to anchor the plant and to spread out. [4] Soil meets those needs by way of air and water pore spaces. It meets those needs by way of nutrients from infiltration and percolation of water, which contains hydrogen, nitrogen, and oxygen from the air. And it meets those needs by way of nutrients from the breakdown of dead and dying organisms such as earthworms and microarthropods. And it also meets those needs by way of protection from extremes of wind, temperature, and moisture. [5] It's also possible, however, for plants to grow in the air, soil-less mediums, and water as long as the basic needs of growth and protection are met.

∙ 15y agoNo. There are high-tech farming methods that uses aeroponics (roots in the air) and hydroponics (roots in the water). The soil is the thing that holds the plant, so without the soil, given that it is well taken care, it can still grow

∙ 13y agoNo it is not needed. In the rain forest, plants grow on the branches of trees. Since it cannot take water from the soil. It takes in moisture from the air and uses it as water.

Do plants need to eat?
yes, nutrients in the soil, sunlight for photosynthesis, and co2
Where do green plants get the ingredients they need for photosynthesis?
Water is absorbed from soil . CO2 is from atmosphere.
Where do plants normally obtain most of their nutrients from?
Plants are autotrophs, meaning they make their own food - plants use the energy from sunlight to create sugar, which they then use for metabolic energy. Other nutrients are drawn from either the soil or the air around the plants.
How do plants obtain magnesium from the soil?
All the plants, who need photosynthesis for a chemical reaction to light energy, will need Magnesium. Magnesium is classified as an alkaline earth metal. It is the 8th most frequent element found in the Earth's crust. Its an elaborated issue. All plants need Chlorophyl to be transferred to energy (sun light) will need the help of Magnesium.
What do plants eat in the desert?
Plants produce their own food through photosynthesis but absorb water and minerals from the soil.
Do plants need to eat?
yes, nutrients in the soil, sunlight for photosynthesis, and co2
How do plants obtain the water they need for photosynthesis?
Plants get the water they require for photosynthesis by absorbing from the soil through their root systems. It is then transported up the stem and to the leaves where is is used to synthesise sugars through photosynthesis.
Where do green plants get the ingredients they need for photosynthesis?
Water is absorbed from soil . CO2 is from atmosphere.
Do plants need light to photosynthesis?
yes and they also need water and some fresh soil ☺
Where do plants get ingredients?
Plants get the nutrients that they need from the soil and water. They get the ingredients to make their own food through photosynthesis.
What do plants get from the soil that is for photosynthesis?
Water.
Where do plants get these ingredients?
Plants get the nutrients that they need from the soil and water. They get the ingredients to make their own food through photosynthesis.
Why do plants need nutrients in the soil?
Plants need fertilizer to live and to grow green and strong.
What nutrition do plants need to live?
Minerals from water, nutrients from soil, energy from the sun (made in the process of photosynthesis)
Do plants receive their nutrients chiefly from sunlight?
Plants need sunlight for photosynthesis, but they get many of their nutrients from the soil. That is why farmers use fertilizer on their fields, and organic growers add compost to soil. As plants use nutrients from the soil, it needs to be replenished for the next crop.
How does the plants gets the substances it needs for photosynthesis?
Plants need only two substances for photosynthesis, water and carbon dioxide. Water is absorbed from the soil (or from the water if they are acquatic plants) and carbon dioxide is absorbed from the air (or again, from the water if the plants grow underwater).
What do plants need to grow other than carbohydrates?
Plants need:Sunlight, water and soil to make photosynthesis and growth.
