Good soil is rich with nutrients so plants have an abundant food supply to support healthy development. Unfortunately, many native soils often lack essential minerals like nitrogen, phosphorus, and potassium, which means plants have trouble reaching their full potential.

Not all plants need soil to grow. Some do better in soil compared to other growing mediums. Plants need minerals and nutrients, such as nitrogen, potassium, and phosphorous. Soil is an effective way of delivering those nutrients cost-effectively. You can also use alternative delivery systems like hydroponics, aeroponics, and aquaponics to achieve t...
Plants only need soil because of the nutrients and the hold the soil provides the plant roots. This way, plants can stand upright. But nutrients are also provided through water and watering. Roots can get hold in different mediums such as legal and other materials. Therefore, plants do not need the soil itself but the benefits it provides. I grow m...
Regardless of the type, every plant has five key elements to grow: light, water, air, heat, and nutrients. Getting nutrients to a plant’s roots is easier done with soil. Soil holds moisture, letting the plant drink what it needs. It also keeps the roots warm while providing the right amount and type of water. Soil also delivers oxygen to the plant’...
Hydroponics
A hydroponics system swaps out soil for water. Not all plants do well when grown hydroponically, but those that do thrive. These are typically used to increase crop yields and the year-round growing of shallow-rooted vegetables. The water is oxygenated, providing support for the roots through the following mediums that won’t compact under consistent moisture: 1. Rock wool 2. Vermiculite 3. Coco coir 4. Peat moss Light is still needed, as are pH controland nutrients. The only difference to gro...
Aeroponics
Aeroponics is a sub-set of hydroponics, minus the growing medium to support the roots. Instead, net pots, closed-cell foam rings, or other types of pots are used to suspend plant roots in the air. But this still provides support for the stems and roots. Aeroponics works by misting the roots directly with a nutrient-rich solution rather than keeping them consistently submerged, according to Science Direct. It is a more technical setup, requiring more maintenance to prevent mineral accumulation...
Aquaponics
Aquaponics is a hydroponics system with fish. It’s essentially an aquaculture-hydroponic hybrid. You feed the fish; the fish waste becomes the plant food. No fertilizer is needed, although what is needed is pH adjustment to keep the fish and the plants alive. Aquaponics is for food cultivation and not just for decorative purposes. This is different from growing freshwater aquarium plantsthat don’t contribute the same to an aquaponics ecosystem. The purpose of aquaponics is to grow editable pl...
Every method of gardening has its pros and cons. Soil is the most convenient and it’s easily understood. There’s plenty of dirt, and you can replace it easily with a potting mixfor most plants. Hydroponics, aeroponics, and aquaponics are far more technical and incur more operational expenses. The main advantage of these is for year-round growing in...
What Plants Will Always Need Soil?
Any plants with deep roots will always require soil. These include deep-rooted vegetables such as potatoes, sweet potatoes, carrots, onions, and turnips. The size of the spread and growth will also be a factor for indoor gardening. Naturally, space limitations will prevent larger plants from being grown in anything other than soil.
Can plants usually grown without soil be transplanted in soil?
You must be careful to avoid transplant shock, but you can certainly transplant plants from one medium to another. Starting seeds, seedlings, or cuttings indoors with hydroponics or aeroponics systems can be beneficial for getting a healthy start to root development. The biggest problem with transplanting to soil is transplant shock. This can be minimized by keeping the soil conditions the same over time to allow the roots to acclimate to their new growing climate. Plant roots are regularly u...

- Light. All plants need some amount of light to survive. Light is the energy source used to convert carbon dioxide into food. Different plants grow best in various types of light and both amount and intensity are important.
- Air. Like all living things, plants need to breathe. They pull carbon dioxide from air and use carbon to break down sugars for food and energy to fuel new growth.
- Water. Water makes up to 95 percent of a plant’s tissues and is responsible for cooling and, transporting nutrients and sugars absorbed by roots to feed the rest of the plant, and structural support.
- Nutrients. Nutrients are plant food and combinations of vitamins, minerals and carbohydrates that fuel functions necessary for survival. Nutrients keep plants healthy and provide energy for all new growth from roots to leaves and flowers to fruits.
12.1 Soils, Fertility, and Plant Growth – The Science of Plants. Learning objectives. By the end of this lesson you will be able to: Describe how soil texture and soil structure affect plant growth. Use simple tests to determine the texture of soil. Determine the meaning and impact of the three numbers typically displayed on fertilizer labels.
Mar 19, 2024 · Healthy soil is essential for growing plants, a lawn, and trees; no matter what soil you start with, you can make it healthy. It involves more than buying a bag of fertilizer and spreading it around. It includes knowing more about the soil, pH, organic content, composition, and changes you can make.

Soil performs four major functions: It provides habitat for fungi, bacteria, insects, burrowing mammals and other organisms; It recycles raw materials and filters water; It provides the foundation for engineering projects such as buildings, roads and bridges; and. It is a medium for plant growth.
Just like how we eat food for energy, plants need soil because the soil itself have nutrients that help plants survive, such as nitrogen and potassium that can only be found from the soil. If you dig out the soil and look at the bottom of trees and many plants, you can see a lot of roots.
