Farming weather
Soil temperatures today read surface 15.1 °C, 6 cm 18.9 °C, 18 cm 22.2 °C, 54 cm 21.2 °C. Soil moisture sits at 0-1 cm at 0.08 m³/m³, 3-9 cm at 0.14 m³/m³, 27-81 cm at 0.23 m³/m³. For maize, the root-zone reading is below the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 45 mm against only 0 mm of expected rain — a 45 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 06:00 on 2026-06-21, with winds at or below 15 km/h and no rain expected. Heat stress is likely for wheat with highs reaching 33 °C (threshold 32 °C). Projected growing degree days over the next week: maize 95, wheat 134.
