Intra-field heterogeneity of soil properties, such as organic carbon (SOC), nitrogen (N), phosphorous (P), exchangeable cations, pH, or texture, is a function complex interactions between biological factors, physical and historic agricultural management. Mapping the crop growth final yield quantifying their link with properties can contribute to an optimization amendment/fertilizer application ...

Hyperspectral reflectance derived vegetation indices (VIs) are used for non-destructive leaf area index (LAI) monitoring for precise and efficient N nutrition management. This study tested the hypothesis that there is potential for using various hyperspectral VIs for estimating LAI at different growth stages of rice under varying N rates. Hyperspectral reflectance and crop canopy LAI measuremen...

Larix chinensis Beissn., as a native, dominant and climate-sensitive coniferous species at Mount Taibai timberline, Qinling mountains, is rarely disturbed by anthropogenic activities; thus, it an ideal proxy for the investigation of climate change or vegetation evolution. In this study, we applied dendrochronological methods to L. tree-ring series from Mt. investigated relationships between wid...

Pine wilt disease (PWD) has become increasingly serious recently and causes great damage to the world’s pine forest resources. The use of unmanned aerial vehicle (UAV)-based remote sensing helps identify nematode trees in time a feasible effective approach precisely monitor PWD infection. However, rapid high-accuracy detection not been well established complex terrain environment. To this end, ...

Vegetation indices (VIs) are widely used in long-term measurement studies of vegetation changes, including seasonal vegetation activity and interannual vegetation-climate interactions. There is much interest in developing cross-sensor/multi-mission vegetation products that can be extended to future sensors while maintaining continuity with present and past sensors. In this study we investigated...

Uncrewed aerial systems (UASs) provide high temporal and spatial resolution information for crop health monitoring informed management decisions to improve yields. However, traditional in-season yield prediction methodologies are often inconsistent inaccurate due variations in soil types environmental factors. This study aimed identify the best phenological stage vegetation index (VI) estimatin...

[1] MODIS-based leaf area index (LAI) and normalized difference vegetation index (NDVI) are used to examine detailed information regarding actual growing season and total annual production for various regions. Overall, MODIS LAI has larger variability and demonstrates more information regarding the evolution and structure of the seasonal vegetation characteristics. In contrast, the NDVI saturat...

Abstract The forestry and Other Land Use (FOLU) sector in Indonesia is expected to contribute 60% of the greenhouse gas emission reduction. priority location for enhancing carbon stock as mitigation action natural forests, such Mount Halimun Salak National Park (MHSNP). objectives this research were estimate vegetation cover changes 2016, 2019, 2022, analyze programs affecting forest MHSNP.
