URIBE-OROZCO, María E. et al. Effect of seaweed Sargassum vulgare C. Agardh in soil and the development of coriander plants. Idesia [online]. 2018, vol.36, n.3, pp.69-76. ISSN 0718-3429.

In the present study our evaluated the effect of the application of seaweed dry meal Sargassum vulgare on poor soil and on the growth of coriander plants was evaluated. The results of the analyzes carried out on the soil showed that it is a sandy soil with a pH of 6.4 and CE of 0 mS / cm, and that at the end of the experiment the treatments that modified these variables were fertilizer with a pH of 5.62 and CE 1.07 and with 9 g of flour with pH of 7.92 and CE of 0.22 mS / cm. Results of the total length and dry weight of coriander they indicate that from the productive point of view, the best effects in the development of the plant are generated by the application of 6 and 9 grams of flour with a longer length and amount of biomass generated which indicates that the greater development of coriander plants may be influenced by the organic matter and the bioactive compounds that the flour contributes to the soil. Future studies should be conducted to determine the biotechnological potential of algae and their bioactive compounds for the sake of a sustainable agricultural use.
