Soils are increasingly recognized as major contributors to ecosystem services such food production and climate regulation (1, 2), demand for up-to-date relevant soil information is soaring. But communicating among diverse audiences remains challenging because of inconsistent use technical jargon, outdated, imprecise methods. Also, spatial resolutions maps most parts the world too low help with practical land management. While other earth sciences (e.g., climatology, geology) have become more...
Estimation of carbon contents and stocks are important for sequestration, greenhouse gas emissions national balance inventories. For Denmark, we modeled the vertical distribution soil organic (SOC) bulk density, mapped its spatial at five standard depth intervals (0−5, 5−15, 15−30, 30−60 60−100 cm) using 18 environmental variables as predictors. SOC was influenced by precipitation, land use, type, wetland, elevation, wetness index, multi-resolution index valley bottom flatness. The highest...
Abstract The effects of pH on nutrient availability are not solely caused by to the reaction with soils but an interaction between these and rate uptake plants. Some specific particular ions, important aspect is that plant roots soil particles both have variable charge surfaces. This influences availability, in opposite directions. Sulfate example this interplay. Its sorption decreases markedly increasing thus “soil availability” increases. However, also “plant decreases. For phosphate,...
There is a growing need for spatially continuous and quantitative soil information environmental modeling management, especially at the national scale. This study was aimed predicting particle‐size fractions (PSF) Nigeria using random forest model (RFM). Equal‐area quadratic splines were fitted to Nigerian legacy profile data estimate PSFs six standard depths (0–5, 5–15, 15–30, 30–60, 60–100, 100–200 cm) GlobalSoilMap project specification. We applied an additive log‐ratio (ALR)...
