Synthesis Of Bio Fertilizer Using Fish Waste And Its Utilization- An Eco-Friendly Approach
C.M. Noorjahan
Abstract
Mindless usage of chemical fertilizers and spraying pesticides to increase yields have made farming a commercial exercise profiting only some private companies rather than small farmers. Application of chemical fertilizers to increase the food production slowly robs the soil nutrients, harm the soil fauna and microbes and cause side effects to the consumers. Fish processing industry is one of the important sectors that generate large amounts of waste by processing and also through fish markets. The disposal of this fish waste material poses a big problem. Addressing this issue would also solve the problem of pollution and waste disposal. Hence this study aims to determine biochemical components - carbohydrates, amino acids, fatty acids, minerals – calcium and zinc present in fish waste, to analyse nutrients present in soil before and after addition of fish manure, to synthesize an eco-friendly bio fertilizer using fish waste and test its efficiency on the germination and growth of balsam plant – Impatiens balsamina and the growth of the plant were compared with that of the same plants that were grown using chemical fertilizer and commercially available fish waste fertilizer. The results of the study revealed that the maximum growth of the plant was recorded using synthesized bio fertilizer than that of chemical fertilizer and commercially available fish waste fertilizer.
