Seaweed liquid fertilizer
Seaweed liquid fertilizer is a type of organic fertilizer derived from various types of seaweed. It is valued for its rich nutrient content, including microelements which don’t appear in standard fertilizer, such as sulphur, as well as plant metabolites which can support the growth of mycorrhizal fungi and nitrogen-fixing bacteria that benefit plant health and growth.
Summary of the study (1) says the efficacy of Seaweed Liquid Fertilizer of different concentrations obtained from green seaweed Ulva lactuca was assessed on the growth, pigments, total chlorophyll, total protein, total carbohydrate and total lipid and the yield of a flowering plant Tagetes erecta.
The combined effect of 1.0% SLF of U. lactuca with different proportions of recommended rate of chemical fertilizers was also made on the test plant. Among the concentrations, plants that received with 1.0% SLF and 50% recommended rate of chemical fertilizers showed a maximum growth characteristic, number and fresh weight of flowers.
