This image shows an experiment on seagrass planting using a bamboo quadrat to define the planting area on coastal mudflats. Two researchers are planting young seagrass shoots within the frame as part of the development of a new technique to enhance the survival rate and growth of seagrass in natural environments.
Tape Seagrass (Enhalus acoroides) is a vital ecosystem with the potential to significantly lower the amount of carbon dioxide, one of the primary greenhouse gases responsible for global warming, because it has greater carbon sequestration ability. Seagrass ecosystems have been severely damaged all over the world, and restoration is urgently needed. This present research intended to innovate and experiment on processes based on natural materials with the goal of optimizing the survival of E.acoroides. There were four methods used during testing: (1) Bamboo Quadrat, (2) Sugarcane pot, (3) Sugarcane pot and Bamboo quadrat, and (4) Traditional Wooden Stake Anchoring and control group. The average survival percentage was highest of Sugarcane pot and Bamboo quadrat with 74.07%, and lowest in the control group with 7.41%. An ANOVA test at a 0.05 significance level revealed that there was a significant relationship between planting technique and seagrass survival percentage. There were no statistically significant differences at the 0.05 level for the growth measurements of leaf length, leaf width, and number of leaves among the surviving samples. Soil quality, both before and after planting in terms of pH and organic content, did not reveal any significant difference. Whereas, after planting, nitrogen (N), phosphorus (P), and potassium (K) content was greater.
