Grimbergen farming weather

Soil temperatures today read surface 22.3 °C, 6 cm 24.5 °C, 18 cm 24 °C, 54 cm 18.4 °C. Soil moisture sits at 0-1 cm at 0.26 m³/m³, 3-9 cm at 0.27 m³/m³, 27-81 cm at 0.3 m³/m³. For wheat, the root-zone reading is within the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 47 mm against only 28 mm of expected rain — a 19 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 06:00 on 2026-06-21, with winds at or below 15 km/h and no rain expected. Heat stress is likely for wheat with highs reaching 37 °C (threshold 32 °C). Heat stress is likely for maize with highs reaching 37 °C (threshold 35 °C). Projected growing degree days over the next week: wheat 168, maize 129.
