Boon of Seaweed Liquid Fertilizer in Agriculture

Now-a-days, the synthetic fertilizers are commonly using in agriculture when compared with organic fertilizers. The continuous use of chemical fertilizers are diminishing soil fertility, soil erosion, health threads to human, livestock and also microbial community present in the soil. To overcome this problem and to increase the efficiency of plant cultivation, seaweed extracts can be used as fertilizers in sustainable agriculture. The seaweed liquid fertilizer (SLF) or suspensions or extracts obtained from algae gain a commercial importance and it can be an alternative treatment especially for organic farming. The application of seaweed fertilizers for different crop plants is of great importance to substitute/supplementary to the inorganic fertilizers and to reduce the cost of production. The current research indicates that the extract from seaweeds are found to be supplementary to chemical fertilizer due to high level of organic matter, micro and macro elements, vitamins, fatty acids and growth regulators. Therefore, the usage of SLF can minimize the quantity chemical fertilizers for sustainable yield of various crop plants.
