TL;DR: In this article, the authors developed and analyzed a global soil visible-near infrared (vis-NIR) spectral library, which is currently the largest and most diverse database of its kind, and showed that the information encoded in the spectra can describe soil composition and be associated to land cover and its global geographic distribution, which acts as a surrogate for global climate variability.

TL;DR: In this article, the authors compared nine colour space models and a redness index: Munsell HVC, RGB, decorrelated RGB (DRGB), CIE XYZ, CIE Yxy, CIELAB and CIELCH.

TL;DR: The aqp package was designed to support data-driven approaches to common soils-related tasks such as visualization, aggregation, and classification of soil profile collections and sought to advance the study of numerical soil classification by building on previously published methods within an extensible and open source framework.

TL;DR: In this article, the effect of Nitrification Inhibitors (NI) on ammonium (NH4+) emissions was investigated in both pasture and cropping soils and from both applied urine and urea with NI (e.g., dicyandiamide (DCD), ATC [4-amino-1.2,4-triazole]).

TL;DR: By the end of 2020, the first worldwide product that fully meets the GlobalSoilMap specifications will be delivered, and the pro and cons of top-down and bottom-up approaches to produce such maps are discussed and their complementarity is stressed.
