Abstract

This study aimed to evaluate the effectiveness of jellyfish chips in promoting the survival and growth of Pinus thunbergii seedlings in a coastal area based on a five-year field investigation from 2012 to 2016. Seedling survival rate was significantly higher in the treatment (96%) than in the control (75%) group in 2012. Furthermore, the height of five-year-old seedlings after plantation in 2012 was significantly greater in the treatment (3.41 m) than in the control (2.32 m) group (t=10.151; p-value<0.01). These results revealed that jellyfish chips can improve soil condition by enhancing moisture retention during the early growth stages and supplying nutrients to the seedlings over time. Our findings indicated that jellyfish chips could be used effectively as an organic fertilizer for growing coastal disaster prevention forests.
