Arwal farming weather

Soil, irrigation, spray-window and crop-stress guidance for Bihar, India.

Field summary

Soil temperatures today read surface 30.2 °C, 6 cm 31.5 °C, 18 cm 34 °C, 54 cm 32.1 °C. Soil moisture sits at 0-1 cm at 0.21 m³/m³, 3-9 cm at 0.21 m³/m³, 27-81 cm at 0.26 m³/m³. For wheat, the root-zone reading is within the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 46 mm against only 4 mm of expected rain — a 42 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 05:00 on 2026-06-22, with winds at or below 12 km/h and no rain expected. Heat stress is likely for wheat with highs reaching 39 °C (threshold 32 °C). Heat stress is likely for rice with highs reaching 39 °C (threshold 35 °C). Heat stress is likely for sugarcane with highs reaching 39 °C (threshold 38 °C). Projected growing degree days over the next week: wheat 205, rice 167, sugarcane 153.
