Farming weather
Soil temperatures today read surface 26 °C, 6 cm 28.1 °C, 18 cm 29.2 °C, 54 cm 27.3 °C. Soil moisture sits at 0-1 cm at 0.39 m³/m³, 3-9 cm at 0.39 m³/m³, 27-81 cm at 0.41 m³/m³. For wheat, the root-zone reading is above the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 36 mm against only 11 mm of expected rain — a 25 mm deficit, so irrigation will be needed this week.
