Aeroponics Farming is a soilless farming method in which plants are grown without the need for soil in a misty environment. Plant roots are suspended in the air and irrigated with a nutrient-rich mist in aeroponics. This is not the same as hydroponics, in which the roots of the plants are immersed in a solution containing nutrients and water. The growing popularity of aeroponics in India can be due to its several advantages, including reduced water usage, increased crop yields, and the capacity to cultivate crops in locations with limited space. Herbs, salads, and leafy greens are a few frequent crops grown in aeroponic systems.
In this article, we will look into the Aeroponics System in detail. We will also look into the examples, advantages, disadvantages, challenges, and prospects of Aeroponics Farming in India.
What is Aeroponics Farming?
The method of growing plants in an air or mist environment without the need for soil or an aggregate medium is called aeroponics. From the Greek words aer (“air”) and ponos (“work”), the word “aeroponic” is derived. Aeroponics’ basic method involves suspending plants in a closed or partially closed space and sprinkling their lower stems and dangling roots with an atomized or sprayed solution rich in nutrients. The canopy, or upper part of the plant, reaches above and consists of the leaves and crown. The roots are kept apart by the plant support structure.
Aeroponics Farming Definition
Aeroponics farming is a modern method of growing plants without soil, using a nutrient-rich mist to deliver essential nutrients directly to the plant roots. This method allows for increased oxygen exposure to the roots, promoting faster and more efficient nutrient absorption.
Aeroponics System
The two living components in the aeroponics system are described as follows:
- Roots: The roots beneath are cleanly divided by the structure of the plant supporting it.
- Canopy: The term “canopy” describes the crown and leaves of a plant, which are often higher than the structural supports of the plant.
Aeroponics depends on hydroponics to fulfill this need. This is due to the demand for a backup system in case the aeroponics system fails to provide the plants with the nutrients they need. In high-pressure aeroponics, a 20–50 mm mist head is used to deliver nutrients to the roots using a high-pressure (80 psi) diaphragm pump.
Examples of Aeroponics
Here are some examples of plants that aeroponics can be used to grow:
- Greens with leaves: Kale, spinach, and lettuce.
- Herbs: cilantro, mint, and basil.
- Other plants: cucumbers, tomatoes, strawberries, and marijuana.
Types of Aeroponics
The following are the types of aeroponics:
Low Pressure Units
Plant roots are suspended above nutrient solution reservoirs in low-pressure aeroponic gardens, where the solution is supplied by low-pressure pumps. These systems work well for small-scale cultivation and for demonstration of aeroponic concepts.
High Pressure Devices
For the production of high-value crops, high-pressure aeroponic systems that make use of sophisticated technologies and mist generation are frequently used. These technologies include pressurized delivery systems, nutrition sterilization, and enhanced air and water purification.
Commercial Systems
Commercial systems are designed to increase crop maturity and prolong plant life. These systems comprise biological systems and high-pressure device hardware. These systems improve production and efficiency by combining data collection, monitoring, analytical feedback, and internet connectivity. They also allow for many crop rotations on a continuous commercial scale.
Aeroponic Farming in India
India has a long history of agriculture, and interest in aeroponic farming has grown recently. India may gain a lot from aeroponic farming, including increased crop yields, reduced water usage, and the capacity to cultivate food in constrained areas. With up to 90% less water used than conventional farming techniques, this environmentally friendly and sustainable approach is appropriate for metropolitan settings with limited arable land. Also, aeroponics farming makes crops safer and healthier to eat by doing away with the need for pesticides and herbicides. India’s aeroponics farming industry appears to have a bright future as a result of the government’s promotion of vertical farming and the introduction of laws supporting this innovative technique. Aeroponic farming hence has the potential to transform Indian agriculture and increase food production
Advantages of Aeroponics Farming
The following are the advantages of aeroponic farming:
1. Higher yields
A considerable portion of a plant’s roots are buried in the ground while farming conventionally. This restricts the amount of water and nutrients that the plant can get. Because of this, plants cultivated in aeroponic systems usually yield more than those grown on regular farms.
2. Less Water Used
Compared to conventional agricultural methods, aquaponics uses much less water. Up to 90% less water can be utilized in some situations.
3. Decreased Application of Fertilizer
In an aeroponic system, fertilizers are not required because the water mist provides the plants with all the nutrients they require. This lowers the impact on the environment and costs.
4. No need for Pesticides
Aeroponic systems don’t require pesticides because there isn’t any soil for them to live in. This lowers the impact on the environment and costs.
5. Less Use of Land
Because aeroponic systems can be constructed vertically, less area is needed for cultivation. There is less space in metropolitan places, therefore this is very helpful.
6. Year-Round Agricultural Growth Possible
Irrespective of the weather, crops can be grown year-round using aeroponic systems. This boosts food output and makes fresh products more widely available all year round.
7. No Pollution of the Soil
When using traditional farming methods, soil contamination can be a serious problem. Fortunately, there is little chance of contamination because aeroponic systems do not require soil.
8. Enhanced Crop Security
Aeroponic systems eliminate the need for soil, thus there’s no chance of damaging germs or parasites contaminating the crops. Because of this, aeroponic farming methods are perfect for producing food that people or animals will eat.
9. Suitable for a Broad Range of Agricultural Cultivation
A wide variety of crops, including fruits, vegetables, herbs, and flowers, can be grown in aeroponic systems. As a result, farmers can produce more goods and make more money.
Disadvantages of Aeroponics Farming
The following are the disadvantages of aeroponics farming:
1. Proper Knowledge and Training
Starting requires not just the essential finances, but also the necessary skills and training. An individual must undergo thorough instruction on keeping the aeroponics system clean before using it. This system is backed by science and is dependent on ever-evolving technology, thus its conservators must constantly improve their skills.
2. Sophisticated Equipment
It involves challenges in maintaining the material components. There are various components in this system, and if they are not properly maintained, some of them may stop working.
3. Requirement of Artificial Light
Maintaining the proper light and air supply for the exposed portion of the plant can occasionally be challenging in the closed or indoor aeroponics farming method.
Challenges of Aeroponics Farming
Aeroponic systems come with specific challenges. Some of these challenges are:
- The first challenge with aeroponics is that to keep the plants growing in the best conditions possible, the atmosphere must be continuously monitored and adjusted.
- The fact that setting up and maintaining an aeroponic system might be more expensive than other growing system types presents another challenge.
- The need for electricity for aeroponic systems to function presents a third challenge. In remote places where electricity is not always dependable, this can be problematic.
- The fourth point is that aeroponic systems can be complicated and need regular maintenance. For farmers who are unfamiliar with the technology, this can be challenging.
- Lastly, because the plants in aeroponics systems come into close touch with the misting solution, there is a higher chance of crop contamination.
Aeroponics vs Hydroponics
Aeroponics and hydroponics have similar concepts, however, the processes are extremely different. Both methods are just as sustainable and effective. Resources are needed for both of them but in different kinds and amounts.
