An INTAG system uses various methods, such as stone beds and floating rafts to give plants access to nutrients that are naturally balanced throughout the water. Replicating natural processes ensures that nutrients and even microbial life are prevalent in the system which is beneficial in creating healthy plants.
Food from a well designed aquaponic system has all the macronutrients and micronutrients that food grown in typical soil does. In many cases, aquaponic produce has even more nutrients than soil-grown produce. This is due to farmland having so many nutrients gradually depleted from the soil through planting and harvesting over time.
