Farming weather

Soil temperatures today read surface 16 °C, 6 cm 17.3 °C, 18 cm 18.2 °C, 54 cm 18.6 °C. Soil moisture sits at 0-1 cm at 0.34 m³/m³, 3-9 cm at 0.35 m³/m³, 27-81 cm at 0.36 m³/m³. For maize, the root-zone reading is within the ideal 0.2-0.35 m³/m³ band. Forecast rain (36 mm) roughly covers crop water demand (ET0 25 mm), so irrigation can likely be paused.
