Farming weather
Soil temperatures today read surface 16.2 °C, 6 cm 19.4 °C, 18 cm 19.9 °C, 54 cm 17.2 °C. Soil moisture sits at 0-1 cm at 0.11 m³/m³, 3-9 cm at 0.15 m³/m³, 27-81 cm at 0.27 m³/m³. For maize, the root-zone reading is below the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 35 mm against only 12 mm of expected rain — a 24 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 62, wheat 100.
