Farming weather
Soil temperatures today read surface 18.4 °C, 6 cm 22.4 °C, 18 cm 24.2 °C, 54 cm 20.6 °C. Soil moisture sits at 0-1 cm at 0.05 m³/m³, 3-9 cm at 0.13 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 52 mm against only 0 mm of expected rain — a 52 mm deficit, so irrigation will be needed this week.
