Abstract Wildfires have a significant impact on Soil Organic Carbon (SOC) content and fractionation. Here we used Diffuse Reflectance Spectroscopy (DRS) Machine Learning (ML) algorithms, particularly decision tree-based ones, to assess post-wildfire changes in labile, removable, recalcitrant SOC fractions across six distinct areas with varying wildfire recurrence levels. Once spectral data had been acquired by DRS, the transformation of raw through first second derivatives enhanced...
Total soluble solids (TSS) is a key variable taken into account in determining optimal grape maturity for harvest. In this work, partial least square (PLS) regression models were developed to estimate TSS content Godello, Verdejo (white), Mencía, and Tempranillo (red) varieties based on diffuse spectroscopy measurements. To identify the most suitable spectral range prediction, calibrated four datasets that included following ranges: 400–700 nm (visible), 701–1000 (near infrared), 1001–2500...
The Asian chestnut gall wasp is an invasive pest that causes ecological and economic losses in the management of sweet (Castanea sativa Mill.). therefore needs to be monitored order assess its impact on tree growth fruit yield. As part this work, we propose infestation level classification based number galls per branch. For two orchards infested by wasp, terrestrial light detection ranging (LiDAR) data were used calculate yield was quantified terms nuts burrs. variables statistically...
While populations of the Asian chestnut gall wasp (Dryocosmus kuriphilus Yasumatsu), an invasive pest affecting European (Castanea sativa Miller), have started to be controlled biologically, this still conditions tree development. With aim assessing plant health status as a means monitoring infestation, we used field spectroradiometer collect data from leaves taken 83 trees in two orchards. We calculated characteristic spectral signatures for and after training validation, developed...
