This paper describes the technical development and accuracy assessment of most recent improved version SoilGrids system at 250m resolution (June 2016 update). provides global predictions for standard numeric soil properties (organic carbon, bulk density, Cation Exchange Capacity (CEC), pH, texture fractions coarse fragments) seven depths (0, 5, 15, 30, 60, 100 200 cm), in addition to depth bedrock distribution classes based on World Reference Base (WRB) USDA classification systems (ca. 280...
Abstract. SoilGrids produces maps of soil properties for the entire globe at medium spatial resolution (250 m cell size) using state-of-the-art machine learning methods to generate necessary models. It takes as inputs observations from about 240 000 locations worldwide and over 400 global environmental covariates describing vegetation, terrain morphology, climate, geology hydrology. The aim this work was production properties, with cross-validation, hyper-parameter selection quantification...
Background Soils are widely recognized as a non-renewable natural resource and biophysical carbon sinks. As such, there is growing requirement for global soil information. Although several information systems already exist, these tend to suffer from inconsistencies limited spatial detail. Methodology/Principal Findings We present SoilGrids1km — 3D system at 1 km resolution containing predictions selection of properties (at six standard depths): organic (g kg−1), pH, sand, silt clay fractions...
Aim It has been suggested that on a global scale, fire activity changes along the productivity/aridity gradient following humped relationship, i.e. intermediate fire–productivity hypothesis. This relation should be driven by differing relative roles of main drivers (weather and fuel) productivity gradient. However, full model across all world ecosystems remains to validated. Location The entire globe, excluding Antarctica. Methods To test hypothesis, we use ecoregions as spatial unit and,...
Abstract. The World Soil Information Service (WoSIS) provides quality-assessed and standardised soil profile data to support digital mapping environmental applications at broadscale levels. Since the release of first “WoSIS snapshot”, in July 2016, many new were shared with us, registered ISRIC repository subsequently accordance licences specified by providers. managed WoSIS contributed a wide range providers; therefore, special attention was paid measures for quality standardisation...
Abstract. The aim of the World Soil Information Service (WoSIS) is to serve quality-assessed, georeferenced soil data (point, polygon, and grid) international community upon their standardisation harmonisation. So far, focus has been on developing procedures for legacy point with special attention selection analytical physical properties considered in GlobalSoilMap specifications (e.g. organic carbon, pH, texture (sand, silt, clay), coarse fragments ( < 2 mm), cation exchange capacity,...
Abstract Aim Understanding the drivers of global diversity has challenged ecologists for decades. Drivers related to environment, productivity and heterogeneity are considered primary factors, whereas disturbance received less attention. Given that fire is a factor been affecting many regions around world over geological time scales, we hypothesize regime should explain significant proportion coarse‐scale plant diversity. Location All terrestrial ecosystems, excluding Antarctica. Time period...
A produção de mudas mamoeiro (Carica papaya L.) é uma das etapas principais para obtenção resultados na produtividade, sendo um dos gargalos a cultura. Dentro desse contexto, destaca-se, maneira significativa, utilização fontes alternativas composição substratos, como o esterco bovino. Diante isso, objetivo principal deste estudo foi avaliar qualidade da variedade Hawai em substratos compostos por solo combinado com diferentes proporções O experimento realizado estrutura telado do tipo...
Question: Small and marginal forest populations are a focus of attention because their high biodiversity value as well the risk population decline loss. In this context, we ask to what extent small, Quercus suber (Cork oak) located in eastern Iberian Peninsula (Valencia, Spain) has capacity for self-regeneration factors that determine its recruitment variability. Location: Pinet Spain). Methods: We performed spatially explicit sampling both potential parameters could account Using regression...

To better address the growing demand for soil information ISRIC - World Soil Information has developed a centralized database shared benefit of international community. This database, hereafter referred to as WoSIS (World Service), been designed in such way that, principle, any type data (point, polygon, and grid) may be accommodated. However, will only provide quality-assessed consistent format, with detailed on lineage conditions use. Data derived from used pressing challenges our time...
