The FOSS4G conference is an annual global conference around Open Source Geospatial software. ISRIC – World Soil Information is an active participant in various open source communities, which shared their current and upcoming activities at the conference. This post highlights some of the presentations and contains links to the videos.

Since ancient times, people have believed in the sacredness of the earth and honor soil with different traditions. Sometimes these traditions include engaging in eating soil, also called geophagy. From 1 November until 17 December a new exhibit, Earth as Superfood, showcasing edible soils from around the world begins in two locations on Wageningen University and Research (WUR) campus, in the World Soil Museum and in the Impulse building.

The Munsell Soil Color Chart is one tool soil scientists use to describe soils in a standardised way.

Though we may not recognise it on a daily basis, standards are important for all of us. They help us work together, to measure progress, and to ensure quality and fairness.

Filtration of soil extracts for the determination of K-AA.

Multi-element soil extractions, like Mehlich 3, gained popularity in recent years. Mehlich 3 (M3) is a cost-effective method as it extracts macronutrients, including phosphorus and potassium, as well as micronutrients from soil samples. Availability of M3 data presents challenges for the use of soil and crop models that are calibrated based on different soil tests.

A visualization of map error presented in the journal article 'Spatial cross-validation is not the right way to evaluate map accuracy.'

There are different ways to evaluate map accuracy, and ISRIC pedometrician and senior researcher Gerard Heuvelink recently gave a talk on what he considers to be the gold standard of soil map accuracy assessments: design-based probability sampling.

Soil spectroscopy is a rapidly growing field of research used to measure soil properties and generate soil data. Along with the increased use of soil spectroscopy, sound and standardised procedures are needed for soil spectral measurements, analysis, storage, exchange and prediction of soil properties.
