Farming weather

Soil temperatures today read surface 15.5 °C, 6 cm 16.4 °C, 18 cm 18.2 °C, 54 cm 18.3 °C. Soil moisture sits at 0-1 cm at 0.37 m³/m³, 3-9 cm at 0.38 m³/m³, 27-81 cm at 0.34 m³/m³. For maize, the root-zone reading is above the ideal 0.2-0.35 m³/m³ band. Forecast rain (31 mm) roughly covers crop water demand (ET0 28 mm), so irrigation can likely be paused.
