Tri-Cities farming weather

Soil temperatures today read surface 20.1 °C, 6 cm 24.1 °C, 18 cm 26.4 °C, 54 cm 23.3 °C. Soil moisture sits at 0-1 cm at 0.02 m³/m³, 3-9 cm at 0.04 m³/m³, 27-81 cm at 0.09 m³/m³. For maize, the root-zone reading is below the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 56 mm against only 0 mm of expected rain — a 56 mm deficit, so irrigation will be needed this week.
