Hydroponics – Farming the Future

The world’s population, nearing 9 billion, coupled with relentless population growth, poses a significant challenge for humanity in providing sustainable living to current and future generations.

The primary concern is the ongoing land degradation caused by invasive human activities, leading to a decline in forest and agricultural land.

One way to maneuver the current progress toward the future is the use of ‘Hydroponics.’

Hydroponics is commonly known as a form of soilless farming.

It is the process of growing plants in sand, gravel, natural substrates, or liquid, with added nutrients, but without soil.

In conventional agriculture, soil supports a plant’s roots, helping it to remain upright and providing it with the nutrients it needs to grow.

In the case of hydroponics, plants are supported with inert materials, such as gravel, coco peat, and perlite.

Essential nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, etc., are provided to the roots in various ways using nutrient-rich solutions.

A considerable amount of research has been conducted to develop optimal methods for plant cultivation.

Every plant requires certain parameters for its growth.

Similarly, similar conditions are simulated to achieve optimal growth results in a hydroponic system.

Some of the common methods for the cultivation of plants in hydroponics are:

1. Drip system – In a drip system, the nutrient solution is dripped on the plant’s roots to keep them moist.
2. Flood and Drain System – The flood and drain system operates by periodically flooding the plant’s root system with a nutrient-rich solution.
3. Nutrient Film Technique (N.F.T) – In this system, a very shallow nutrient solution continuously flows downward through the tubing; the bare roots of the plants come in contact with the water and can absorb the nutrients from it.
4. Water Culture – In this system, the roots of the plants, suspended in a basket, hang directly into the nutrient solution. The roots remain submerged at all times, 24/7. The necessary oxygen for plants is provided by air bubbles rising through the nutrient solution or from dissolved oxygen in the water.
5. Aeroponics – As the name indicates, the nutrients to the roots of plants hanging in mid-air are provided in the form of mist using a mister or sprinkler at regular intervals. Mid-air hanging provides maximum oxygen to the growing plants.
6. Wick system – In the wick system, the nutrient solution from the reservoir is supplied to the plants using the process of capillary action. Meaning it sucks up water to the plants through the wick like a sponge.

A person can choose from the methods depending on the plant and the feasibility of the process.

Some of the advantages of hydroponic systems are:

• Through hydroponic gardening, plants can be grown anywhere as long as their growth requirements are met.
• This technique does not require pesticides, fertilizers, or other chemicals, as there’s no chance of damage due to soil-borne diseases or pests.
• A monitored environment provides control, irrespective of changing seasons, allowing crops to be grown all year round.
• It’s simple to get complete control over nutrient balance.
• Double yield is achieved, resulting in increased production from the same amount of space, with improved plant health and enhanced nutritional value.
• Ease of harvesting.

The hydroponic practice has yielded excellent results in a very short span of time, thanks to the application of proper knowledge and techniques.

It is extremely beneficial for commercial farmers; hence, it can be said that the new method is surely the future of farming, considering all the expected limitations in the near future.
