The harmful effects of chemical fertilizers on the environment are proven, their excessive use causes serious problems of contamination in soils and groundwater. Biofertilizers represent a viable and sustainable option for agriculture; the reuse of hydrobiological waste is an excellent alternative. After a 90-day experimentation process, the growth of the champion radish was evaluated, in response to biofertilization with hydrobiological residues, obtained from residues of marine algae and fish. Seven treatments were carried out in pots: homemade biofertilizer, biofertilizer with hydrobiological residues (6 types of mixtures), diluted in four doses: 0.5:20, l:20, 1.5:20 and 2:20 ml/L of water, and a control without fertilizer (only water); all treatments were doubled. The combination 60% fish - 40% algae, with a dose of 2:20 ml/L of water, had better results in terms of growth, since fish is high in nitrogen and phosphorus, while marine algae are rich in potassium. , proving to be a stable combination for good growth. High doses in seaweed didn’t have positive effects due to its high boron content. The high values of electrical conductivity and Na concentration are associated with high salinity. Treatments only fish or only algae were not efficient. It was concluded that fish and seaweed residues, in a 60/40 ratio, are efficient to be used as a biofertilizer, with better results compared to other organic sources.
