United Nations predicted that the total population of the world will grow to 8.5 Billion by 2030 and 70% of the population will live in cities. Such population increase comes hand in hand with the need to produce more food to feed them. There are some estimates which suggest that more than 80% of food will be required to feed them. But the major challenge is to produce sufficient for them to sustain as there is only 65% of land which is fertile in the world due to rapid urbanization
To overcome this crisis, there’s the niche method for producing food which allows us to grow plants without soils called Hydroponics. In this method, all the minerals and nutrition are feed to plant directly with the help of the Nutrient Film Technique System (NFT) without any help of soil. We can grow just about any vegetable or fruit using hydroponics such as tomatoes, broccoli, cabbage, eggplants, peppers, basil
In the last decade, Hydroponics has been seen as an auspicious strategy for growing various crops. It can play a great contribution in areas having the limitation of soil & water, also for people who have no land for farming as it is possible to grow short duration crops like vegetables round the year in very limited spaces with low labor. The Global Hydroponics Market has been estimated to cross USD 8.1 Billion in 2019 includes such vegetables as tomato, peppers, cucurbits, lettuce & leafy vegetables, and other food crops. Australia, France, Israel, Netherlands, England, Canada & the USA are the leading countries in hydroponic technology. Among them, Netherlands is the world leader now a day in commercial hydroponic having a farming capacity of 13000 hectors of capsicum, tomatoes, cucumber, and cut flowers. It is 50% of the value of all fruits and vegetables produced in the entire country. Japan already started to produce rice with this technique. Spain & Canada are also planning to expand the area for commercial hydroponic farming. Israel is also in the race to grow berries & citrus fruits & bananas large quantities of in the dry & arid climate. On the other side, Australia is the largest hydroponic lettuce producers in the world. Their strawberry cultivation is larger than the USA and cut flower production is almost equal to the USA.
Now the world is accepting this farming technique due to several reasons i.e.
This technique saves a significant amount of space compared to conventional soil gardening
Elimination of soil also eliminates a lot of the different soil-borne diseases and pests that plague
It saves water up to 70% to 95% then soil farming as water can be captured and reused, rather than allowed to run off and drain to the environment
The decrease in the use of fertilizers of about 50%
Due to the Deliverance of soil, a lot of the different soil-borne diseases & pests can be diminished that plague in traditional gardening.
