Some plants, like root crops, like to live in soil and not in a soilless medium like clay pebbles or gravel as in Aquaponics or Vermiponics. The plants here are thus put in small baskets of soil and then put into the growth medium. The advantage is that you have the water cycling and you have your plants in soil.

Terraponics is an agricultural system that combines elements of aquaponics while incorporating soil as a growing medium as in a wicking bed. In Terraponics, plants are grown in containers or raised beds filled with soil, just like in traditional farming, but the system also utilizes hydroponic and aquaponic principles to enhance water and nutrient efficiency.

Difference between Terraponics, Hydroponics, and Aquaponics:

  1. Hydroponics: In hydroponics, plants are grown without soil, and their roots are immersed in a nutrient-rich water solution. The absence of soil allows for precise control over nutrient delivery, and plants can grow faster since they don’t need to search for nutrients.
  2. Aquaponics: Aquaponics is a combination of aquaculture and hydroponics. Fish are raised in a tank, and their waste provides nutrients for the plants grown in a hydroponic setup. The plants, in turn, purify the water for the fish.
  3. Terraponics: Terraponics incorporates soil as a growing medium, similar to traditional farming. However, it uses hydroponic or aquaponic techniques to enhance water efficiency and nutrient delivery to the plants. The soil acts as a buffer, allowing for a more natural growing environment for the roots.

Benefits of Terraponics:

  1. Enhanced Water Efficiency: Terraponics retains the benefits of soil as a water reservoir, reducing water usage compared to hydroponics. The soil holds moisture, reducing the frequency of watering and ensuring a steady supply of water to the plants.
  2. Nutrient Control and Natural Buffer: Using soil in Terraponics provides a natural buffer against fluctuations in nutrient availability. It allows for a more forgiving system that can better adapt to changes in nutrient levels.
  3. Sustainable Farming: Terraponics promotes sustainability by combining the advantages of hydroponics and aquaponics with the natural fertility of soil. It encourages responsible resource management and reduces the environmental impact of farming.

Plants Suitable for Terraponics:

A wide variety of plants can thrive in Terraponics, including:

  • Leafy greens like lettuce, kale, and Swiss chard.
  • Herbs like basil, parsley, and cilantro.
  • Root vegetables like carrots and radishes.
  • Tomatoes, cucumbers, and peppers.
  • Small fruits like strawberries.

The selection of plants depends on factors such as local climate, available space, and the specific Terraponics setup used.

In summary, Terraponics is a unique agricultural approach that combines the benefits and aquaponics with the use of soil as a growing medium in the form of a wicking bed. By incorporating soil, Terraponics aims to provide a more natural and sustainable way of cultivating crops while still benefiting from the water and nutrient efficiency of hydroponics and aquaponics.

This video describes Terraponics well.

Terraponics is a new field, promoted by some who want their vegetables grown in soil but also see the benefit of the water savings of aquaponics. Much experimentation needs to be done still though.

Terraponics is similar to wicking beds in aquaponics.
