In agricultural activities, fertilization is important. However, in some cases, plants can grow well without continuous fertilization. This due to the influence of plant litter and the presence of undergrowth which is a source of organic matter that supplies nutrients to the soil. The objectives of this study were to know the dynamic of nutrient release from litter decomposition and to find out the amount of nutrient content provided by decomposition of A. mangium and Nephrolepis sp. litter. Fresh litter of A. mangium and Nephrolepis sp. were put in the open area in a 0.2 m2 container with a water tank underneath. The leachate was taken every week, then the macro and micronutrients were analyzed in the laboratory. The results showed that the nutrients in the litter were released gradually through the leaching process from the first week of experiment. This indicates that since the beginning of decomposition process, the nutrients released can be used by plants. The highest nutrient released was potassium equivalent to 76.1 kg K ha−1year−1 for A. mangium and 114.7 kg K ha−1year−1 for Nephrolepis sp. Thus, the presence of litter and undergrowth has the potential to be used as fertilizer and contribute to providing nutrients for plants.

Monitoring vegetation dynamics in terrestrial national parks (TNPs) is crucial for ensuring sustainable environmental management and mitigating the potential negative impacts of short- and long-term disturbances understanding the effect of climate change within natural and protected areas. This study aims to monitor the vegetation dynamics of TNPs in Indonesia by first categorizing them into the regions of Sumatra, Jawa, Kalimantan, Sulawesi, and Eastern Indonesia and then applying ready-to-use MODIS EVI time-series imageries (MOD13Q1) taken from 2000 to 2022 on the GEE cloud-computing platform. Specifically, this research investigates the greening and browning fraction trends using Sen's slope, considers seasonality by analyzing the maximum and minimum EVI values, and assesses anomalous years by comparing the annual time series and long-term median EVI value. The findings reveal significantly increasing greening trends in most TNPs, except Danau Sentarum, from 2000 to 2022. The seasonality analysis shows that most TNPs exhibit peak and trough greenness at the end of the rainy and dry seasons, respectively, as the vegetation response to precipitation increases and decreases. Anomalies in seasonality that is affected by climate change was detected in all of the regions. To increase TNPs resilience, suggested measures include active reforestation and implementation of Assisted Natural Regeneration, strengthen the enforcement of fundamental managerial task, and forest fire management.
