The paper also presents particle size distribution down to 30 cm, and near infrared reflectance (NIR) spectra for the main soil types. This dataset allows evaluating the effects of land use, soil type and texture on SOC content and stock, at regional scale. It also allows inferring SOCg, SOCv and particle size distribution from NIR spectra. Such information is useful for studying and managing soils in the Martinique island and in other tropical volcanic regions. specialized land use and management near infrared diffuse reflectance particle size distribution soil type MARTINIQUE 068 75 1 e13453 [6 p.] 2024 1351-0754 https://www.documentation.ird.fr/hor/fdi:010088949 10.1111/ejss.13453 1351-0754 [F B010088949] https://www.documentation.ird.fr/hor/fdi:010088949 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-03/010088949.pdf IRD - Base Horizon / Pleins textes 2024-03-06 2026-06-12 fdi:010088949 fre
