What are Aquaponics?

Intoduction to Aguaponics

To all farmers,

The advancements in technology have brought about significant changes in various sectors, including agriculture. One area that has embraced these changes is the agriculture sector. Aquaponics, a sustainable method of food production, has emerged as a soil-free technique that combines aquaculture (fish cultivation) and hydroponics (plant cultivation in water with nutrients).

In aquaponics, water from the aquaculture system is directed to a hydroponic system, where nitrifying bacteria break down the by-products into nitrites and then nitrates. These nitrates serve as nutrients for the plants. The water is then recirculated back to the aquaculture system. In the hydroponic system, plants grow with their roots suspended in water, allowing them to access all the water directly without any loss due to ground seepage or evaporation.

The unique feature of aquaponics is that plants develop smaller root structures due to their water-based environment. This enables dense planting, resulting in a significant increase in overall productivity, reaching up to 150%-200% per unit of area.

Aquaponics has proven successful for a variety of crops, such as cucumbers, shallots, tomatoes, lettuce, chilies, capsicum, red salad onions, snow peas, Chinese cabbage, basil, roses, okra, cantaloupe, bell peppers, watercress, coriander, parsley, lemongrass, sage, beans, peas, kohlrabi, taro, radishes, strawberries, melons, onions, turnips, parsnips, sweet potato, cauliflower, cabbage, broccoli, eggplant, and pak choys.

It is important to note that the use of pesticides can harm the fish ecosystem in aquaponics. To maintain the symbiotic relationship between plants and fish, it is recommended to employ non-chemical methods like traps, physical barriers, and biological controls (e.g., parasitic wasps and ladybugs to combat white flies and aphids) or opt for organic pesticides such as Magneto® 10 EC or Biochance® 150SL for pest control.

Let’s embrace the opportunities provided by aquaponics and cultivate sustainable agriculture.

Benefits of Aquaponics

  1. Farmers can benefit from dual income streams by cultivating vegetables and raising fish simultaneously.
  2. This method is environmentally friendly, promoting sustainable agricultural practices.
  3. Plants in aquaponics systems have easy access to water, oxygen, and essential nutrients, ensuring their optimal growth.
  4. The planting density can be significantly increased in a given area due to the ability to grow plants closely together, leading to higher plant populations and increased productivity.
