What is Aquaponics and Organic Farming?

Aquaponics is a soilless farming technique that combines hydroponics (the cultivation of plants in water) with aquaculture (the breeding of fish or other aquatic animals). Essentially, it is a closed-loop system where nutrient-rich water from fish tanks is used to fertilize plants, and in turn, the plants filter and clean the water, which is then recirculated back to the fish tanks. The symbiotic relationship between fish and plants creates a natural balance, eliminating the need for chemical fertilizers and pesticides.

On the other hand, organic farming is an approach that emphasizes the use of natural methods and materials to nurture soil fertility, control pests and diseases, and promote biodiversity. It prohibits the use of synthetic chemicals and genetically modified organisms, focusing instead on sustainable practices such as composting, crop rotation, and the integration of beneficial insects.
