Fertilisation is the feeding of plants, while Fertigation is the feeding of plants by means of first dissolving the nutrients in the irrigation water. Hence the name “Fertigation” which is a combination of the two words “Fertilisation” and “Irrigation”. Advantages of Fertigation Uniform application of the fertilisers throughout the irrigated area. The amounts and […]

Introduction Aquaponics is the combination of aquaculture and hydroponics within a single system. You grow the plants (vegetables) hydroponically using the fish waste as the main source of nutrients. The plants in turn purify the water for the fish. Notes on aquaponics are provided on role player websites (see heading 2). Benefits of the system […]
