Hydroponics: The Future of Sustainable Agriculture

Hydroponics is an innovative means to grow plants without soil. It is rapidly emerging as a sustainable solution to the modern-day agricultural problems. The world’s population is estimated to reach about 9.8 billion by the year 2050 and the demand for food is projected to be 70% higher. Conventional farming systems greatly rely on soil and excess water usage, leading to an inquiry into their sustainability. Hydroponics certainly provides one of the most promising alternatives to some of the most pressing problems of agriculture today. This feature reviews hydroponics as a means to sustainability.

What is Hydroponics?

Hydroponics is the method of growing plants without soil and only by using water, along with aiding additives in a controlled environment. It falls under the field of horticulture. The growth of plants is supported with a growing medium such as perlite, vermiculite or coconut coir, ideally of little nutritious worth for support. The water used is enriched with nutrient solutions. The water is re-enriched and recirculated periodically. In this controlled environment, plants grow faster and yield more produce than those in traditional soil farming.

Advantages of Hydroponics

• Water efficiency: One of the most important aspects of hydroponics is the efficient use of water. In comparison to this, conventional agriculture totally relies on water, from which a high quantity of water either evaporates or runs off and is lost through highly inefficient irrigation. On the other hand, hydroponic systems reuse water and save at least 90% that would otherwise go to waste. 

• Space efficiency: As opposed to conventional farming, hydroponics requires much less space. Space efficiency is done by stacking plants in layers, allowing optimum usage of the area. This advantage particularly benefits urban populations where land is priced at a premium. One subset of hydroponics has gained popularity worldwide is vertical farming. This helps bring fresh produce closer to consumers and reduces the ecological footprint associated with food supply.

• Faster growth and higher yields: Hydroponic plants grow faster and yield more produce as compared to soil-grown plants. The controlled environment, precise nutrient delivery and optimal growing conditions promote healthier plants. This in turn results in more harvests per year. This efficiency is particularly valuable for crops with high market demand, such as leafy greens, herbs and tomatoes.

• Pest and disease control: Soil is a common source of pests and diseases which can prove devastating to crops. Soil being eliminated, hydroponics essentially provides a solution to soil-borne diseases and pests. The controlled environment also allows for easier management of other pests with lesser use of chemical pesticides. In this way, cleaner and healthier produce can be achieved with minimal environmental impact.

Challenges and Considerations

Though hydroponics has a lot of merits, it is not without challenges. 

• The initial cost when setting up a hydroponic system is sometimes very high, most especially with large-scale operations. This technology needs a vast outlay in infrastructural investment, for instance, the grow lights, pumps and nutrient delivery systems. However, such costs are expected to decrease with improvements in the technology and increase in its adoption.

• The other challenge is that one needs a certain level of technical know-how and expertise in order to successfully be able to take care of a hydroponic system. Hydroponics does not wholly rely on natural processes. Thus, the water quality, nutrient levels and environmental conditions have to be monitored with great caution. This may prove to be an obstacle for small scale farmers or those with limited resources and less access to knowledge. 

• Another challenge is the consumption of energy, particularly with respect to indoor hydroponic systems that use artificial lighting. Though the greater efficiency and increased yield of hydroponic farming somewhat offset the costs of energy, such aspects must be looked into in order to have the least environmental effect.

Hydroponics in the Future

Future hydroponics is really bright. Emerging technologies in this sector are working towards making hydroponic systems more affordable, efficient and attainable. Automation and artificial intelligence offer the grower a powerful control of growing conditions in a hydroponic farm, ensuring further yields are fine-tuned for greater precision. Additionally, hydroponics is receiving much popularity in areas that have low quality of soil, lack of arable land or severe climatic conditions.

The techniques that include the concept of growing plants over treated water have already been put into place within countries such as the Netherlands and Singapore, which have developed this as a part of their national agricultural strategies. In India, where the significance of agriculture is huge, hydroponics comes out as a remedy to soil degradation, scarcity of water, and the necessity to feed millions.

The Real Reason Behind Global Suffering

Science and technology have long been seen as the guiding forces of progress, with the potential to solve humanity’s greatest challenges. However, despite rapid advancements, hunger continues to rise, defying our expectations.

Jagatguru Tatvdarshi Sant Rampal Ji Maharaj reveals that this disparity stems from a deeper spiritual cause we are unaware of – We are trapped within the 21 universes governed by Kaal Brahm or Satan. In this territory, equality and justice are elusive, leaving souls in a state of suffering and despair.
