Aquaponics combines aquaculture (the growing of fish and other aquatic animals) and hydroponics (the growing of plants without soil) in one recirculating environment. In aquaponics, the fish produce waste that is converted by the nitrifying bacteria into nutrients for the plants. Plant roots absorb these nutrients to thrive. In return, the plant roots clean and filter the water for the fish to live.
Potassium is one ofthe essential nutrients that plants need to grow. It is one of the three primary macronutrients along with phosphorus and nitrogen. Potassium can affect the shape, size, and vitality of the plants in your aquaponics system. So if you want to grow healthy plants in your aquaponics system, you need to understand and properly manage the potassium in your system.
