Vertical farming is emerging as an approach to growing crops sustainably. The world’s population is rapidly expanding and, the demand for food is also rapidly rising. Traditional farming equipment, techniques, or practices cannot fulfill this demand, so we need a solution. Vertical farming is emerging as an effective solution for feeding people in urban areas, as this technique doesn’t require large farms to produce.
In this blog, we will discuss vertical farming in India, how it works, its advantages and disadvantages, and why this method is the future of agriculture.
What is Vertical Farming?
Vertical agriculture refers to the practice of growing crops in vertical layers. This technique can be used in constructed houses, warehouses, and even small enclosed spaces such as shipping containers. Vertical farms operate in Controlled Environment Agriculture (CEA), where features such as temperature, lighting, irrigation, and nutrients are managed indoors.
While traditional farming involves the use of extensive space for cultivation, vertical farming can grow crops one above the other in containers. This method can be done throughout the year without being influenced by environmental conditions.
How Vertical Farming Works?
Vertical farming requires the plants to grow in a controlled environment to enhance their growth. Some important components needed for growth are light, heat, moisture, and nutrients. In most vertical farms, artificial lighting such as LED is used due to the minimal use of direct natural sunlight. These lights are uniquely designed to emit the wavelengths that the plants require for photosynthesis. Moreover, vertical farms utilise hydroponics or aeroponics to feed the plants’ roots as they are devoid of soil.
Hydroponic systems are based on growing plants in nutrient solutions containing minerals and nutrients. However, the aeroponic systems irrigate the nutrients in the form of a mist that directly reaches the roots of the plant. Both systems provide close control of the growing conditions and, therefore, have higher growth rates and yield than traditional agriculture.
5 Types of Vertical Farming
Vertical farming can be classified into several types depending on the practices adopted for them. Here are the main types:
1. Hydroponic Vertical Farming
Hydroponics is a way of cultivating crops without using soil as the medium for anchoring the roots. In vertical farming, the origins of the plants are placed in a nutrient bath of water.
2. Aeroponic Vertical Farming
Another technique for growing plants without soil is Aeroponics, in which the plant’s roots are sprayed with nutrient solution. This system is similar to a hydroponic system, as it requires less water and more oxygen to reach the roots, facilitating rapid growth.
3. Aquaponic Vertical Farming
Aquaponics is the union of hydroponics and aquaculture. It is a system that uses recirculating water containing fish and plants. The fish release waste that is fed to the plants, which in turn feed on it and purify the water for the fish to live in.
4. Modular Vertical Farming
Modular vertical farming utilises steel-framed modules that stand vertically stacked. It also uses modules or containers that can be added together, just like an extensively connected Lego set. It is designed to accommodate plants within a controlled and enclosed environment and is flexible enough to accommodate various types of crops.
5. Container Vertical Farming
Container vertical farming involves using old shipping containers to produce a specific controlled climatic environment for plant growth. These containers can be stacked, which is suitable for farming purposes in urban areas.
4 Advantages of Vertical Farming
Considering current environmental conditions, we all have a question: is vertical farming eco-friendly or sustainable? Let’s learn more about the advantages in detail :
1. Space Efficiency
The biggest benefit of vertical farming is that it solves the issue of agriculture in less space. This is especially useful in the current situation where space is a major issue, especially in urban areas. Vertical farming at home enables people to produce their own vegetables. Moreover, it addresses the problem of the carbon footprint when transferring produce from one locality to another.
2. Water Conservation
Vertical farming uses less water than conventional farming practices. In a conventional farm, a high percentage of the water is either evaporated or washed away through the runoff. However, in vertical agriculture, the use of water is limited as these farms are artificially built structures.
3. Reduced Pesticide Use
Another advantage of vertical farming is that there are very low chances of pesticide use. Most of the pests that infest plants in outdoor conditions cannot survive in an enclosed vertical farm environment. To a certain extent, this enables the production of fresher and less pesticide-contaminated food.
4. Year-Round Production
Rainfall availability and other environmental factors affect traditional farming practices. However, vertical farming makes it possible for farmers to produce throughout the year in all types of climatic conditions. This means constant production, which is a great achievement for food producers, particularly in regions having unfavourable weather conditions.
Disadvantages of Vertical Farming
The future vertical farming will be very helpful and economically viable for India farmers. However, a few disadvantages need to be discussed in order to resolve them. Let’s learn more about it in detail:
1. High Initial Costs
Vertical farming has the major disadvantage of the high capital required to build the whole structure. It incorporates many technology investments, such as lighting systems, climate control, and nutrient delivery systems.
2. Energy Consumption
In vertical farming, artificial light and a controlled environment are widely used and tend to be energy-intensive. Some vertical farms use power from solar panels or wind turbines, while others work on conventional power, which may be costly.
3. Technical Expertise
Vertical farming involves a highly technical system that requires the attention of highly qualified personnel. Growing crops in a vertical farm requires knowledge of plant biology, engineering, and data analysis among farmers.
4. Limited Crop Variety
Today, vertical farming is most useful for plants with shallow root systems, such as lettuces, herbs and microgreens. Raising larger or more complex forms, like grains, reduces efficiency and can be less feasible in vertical farming.
5. Market Acceptance
There are many benefits of vertical farming, but market acceptance is still needed. People have been used to traditional agricultural produce, which is why they may not be willing to pay more for vertical farming produce. More awareness is needed among consumers that they should try to produce grown on vertical farms.
Future of Vertical Farming
1. Technological Advancements
The future of vertical farming appears rather bright, with many technological possibilities in store. Recent developments in LED lighting, Automation, and data analysis are predicted to improve its feasibility. For instance, improvements in LED lighting are creating new, much more favourable illumination to plant requirements.
2. Integration with Urban Infrastructure
Due to the increasing population in cities, vertical farming will become more critical. It can be developed as part of various residential and commercial premises. Moreover, it will help eliminate the need for transportation and bring the production of food products closer to the consumer.
3. Expanding Crop Diversity
Currently, studies are being conducted to identify other varieties of crops that can be grown under vertical farming. Researchers have been working on methods to produce more types of fruits, vegetables, and even grains through vertical agriculture at home. This will increase crop diversification, which will enable vertical farms to offer the option and make it feasible.
4. Global Impact
Vertical farming technology is still a relatively new field, but as the technology grows, it might revolutionize the agricultural world. Developing countries with limited land or harsh climates can also benefit from vertical farm produce.
Indoor Vertical Farming
The concept of using vertical farming techniques within an indoor environment is slowly becoming popular in India. This method helps grow crops in layers under controlled climatic conditions. Indian farmers are embracing Indoor vertical farming to produce fresh crops all year round without worrying about climatic conditions.
High-tech hydroponics, LED lighting, and controlled environment technologies enable crop yields to be optimised, and water consumption is minimized. Furthermore, vertical farming is more valuable in urban areas where there is less space and demand for fresh produce is high. With an increasing population and the ongoing process of urbanization in India, the idea of indoor vertical farming is a great approach.
