Digital soil mapping and its implications in the extrapolation of soil-landscape relationships in detailed scale [PDF]
Pesquisa Agropecuária Brasileira, 2017 : The objective of this work was to test the extrapolation of soil-landscape relationships in a reference area (RA) to a topographic map (scale 1:50,000), using digital soil mapping (DSM), and to compare these results to those obtained in similar studies

Molecular Ecology, Volume 32, Issue 23, Page 6243-6259, December 2023., 2023 Abstract Declines in soil multifunctionality (e.gsoil capacity to provide food and energy) are closely related to changes in the soil microbiome (e.g., diversity) Determining ecological drivers promoting such microbiome changes is critical knowledge for protecting soil functions.

Journal of Plant Nutrition and Soil Science, Volume 185, Issue 6, Page 720-744, December 2022., 2022 Abstract A 3–4D soil model represents a logical step forward from one‐dimensional soil columns (1D), two‐dimensional soil maps (2D), and three‐dimensional soil volumes (3D) toward dynamic soil models (4D), with time as the fourth dimension. The challenge is to develop modeling tools that account for the states of soil properties, including the spatial ...

European Journal of Soil Science, Volume 73, Issue 5, September–October 2022., 2022 Abstract Digital soil mapping provides estimates of soil properties and, in turn, an understanding of the spatial variation in soil across landscapes. In recent years, several digital soil mapping products have been released across the world. An end user in New South Wales (NSW), Australia, could choose between a global product (SoilGrids), a national ...

Mapping depth to Pleistocene sand with Bayesian generalized linear geostatistical models
European Journal of Soil Science, Volume 73, Issue 1, January–February 2022., 2022 Abstract Spatial soil applications frequently involve binomial variables. If relevant environmental covariates are available, using a Bayesian generalized linear model (BGLM) might be a solution for mapping such discrete soil properties. The geostatistical extension, a Bayesian generalized linear geostatistical model (BGLGM), adds spatial dependence ...
