Reduced running costs – the cost of running a conventional horticultural farm is huge, with the cost of tractors and all the implements needed reaching into the $100's thousands. With Aquaponic systems, there is no ploughing or spraying, reducing the need for large tractors which use large amounts of diesel fuel, and also reducing the need for the farmer to spend alot of their money on synthetic chemicals.
Being exposed to chemicals is not good for us, yet we continue to use them to help grow our food. The farmer has more exposure to these chemicals as they are physically handling them in preparation of spraying. The farmer is also exposed while spraying the liquid, especially if the wind blows it back into the direction of the farmer.
