The highest nutrient
removal rates by fruit harvest were achieved during tomato culture: over a period of more than 3
months, fruit production removed 0.52, 0.11 and
0.8 g m2 d1 for N, P and K in hydroponic and
0.43, 0.07 and 0.4 g m2 d1 for N, P and K in
aquaponic. In summer 2005, about one-third of
NPK removal by the hydroponic system was
achieved by tomato fruits.
