Soil temperature and moisture for any point in Czechia, now and for the next 5 days.

Out of test since 2026-10-20 (the "test version" tag is gone). This is still a model estimate, not an official forecast or warning.
What it shows
- Click anywhere in Czechia to get a 250 × 250 m square with its own soil, terrain, land cover and weather.
- Soil temperature at 2, 5, 10, 20, 30, 50, 75 and 100 cm, with the morning minimum and daily maximum near the surface.
- Soil moisture as % of plant-available water (% VVK) for 0–10, 0–40 and 0–100 cm, and in mm.
- "Vs normal" map layers: moisture 0–40 cm as a percentile of 1991–2020 (same time of year, ±15 days), the soil-temperature departure at 5 cm and, April–October, drought classes S0–S4 from moisture 0–100 cm. The normal is the ERA5-Land reanalysis mapped to the model.
- Erosion on arable land: the long-term water-erosion hazard from the official VÚMOP erosion layers and a daily erosion risk from the rainfall forecast and soil moisture (map layer and location panel).
- A deeper section at 150 and 200 cm, marked lower confidence. Moisture there is shown only as drier or wetter than usual.
- A soil profile to 200 cm, with soil type and geology from the ČGS maps and the layered soil the model uses.
- "Máte jinou půdu?": switch to another soil or land cover found within ~10 km and see the forecast for it.
- Decision cards: sowing, frost and winter, trafficability, conditions for nitrogen fertilising (advisory only) and irrigation.
- An accuracy page comparing the model with ČHMÚ soil-temperature stations.
- Updated 4× a day.

Languages
The site is available in Czech and English. A Czech system language selects Czech, anything else English; the CS | EN switch in the header overrides this and is remembered in the browser (?lang=cs|en in a link also works).
- Strings live in
web/src/lang/cs.js and web/src/lang/en.js (same keys in both; npm test checks this). Use t('key', {param}) and tp('key', n) from web/src/i18n.js.
- The long text page (
jak-to-funguje.html) has one block per language (data-l="cs" / data-l="en").
- Proper names and rock names from the data stay as published; generic labels are translated in
web/src/lang/data-en.js.
