Aquaponics Africa Vegetables

A large variety of vegetables and herbs can be grown in an aquaponic system especially the leafy crops that require high nitrogen.

Vegetables

The nutrient rich water from the fish tanks is pumped into the growbeds where drain pipes distribute it to the plants. Beneficial bacteria in the eco-lagoons break down the fish waste-products into a form ready for uptake by the plants, before the water is pumped back into the fish tank providing aeration for the fish. A large variety of vegetables and herbs can be grown in an aquaponic system especially the leafy crops that require high nitrogen.

As it is a recirculating system, no chemicals are used with either the fish or the vegetables as it would have an adverse effect on them and upset the delicate balance.

The best insect control is prevention. Strict cleanliness in the greenhouse together with all possible steps to prevent contamination and disease must be undertaken.

Air vents should be screened with small mesh mosquito screening All plants brought into the greenhouse should be thoroughly inspected. A disinfectant footbath at the entrance to the greenhouse should be installed. Stick traps and biological controls are used to deal with any problems. Companion planting should be practiced and catchcrops used
