Soil Temperature & Moisture

A lower moisture reading number in centibars (cb) = more saturation & wetness, a higher number means the soil is drier. The soil at this particular site is rich black earth between 0 & 10 cm becoming a mix of brown earth at 15cm & well mixed with clay at 30cm. The soil nearly all dense clay at 60cm.


0-10 CB = Saturated soil. Occurs for several days after irrigation or rainfall

10-20 CB = Soil is adequately wet (except coarse sands which are drying out at this range)

30-60 CB = usual range to irrigate or water (except heavy clay soils). Irrigate at the upper end of this range in cool humid climates and with higher water holding capacity soils

60-100 CB = Usual range to irrigate heavy clay soils

100-200 CB = Soil is becoming dangerously dry for maximum production, proceed with caution.

Soil Info

The soil in Vaughan and much of Woodbridge consists of Peel Clay & Cashel Clay which are both Grey-Brown Podzolic's with good to imperfect drainage & moisture retention. The station is visible above as a star with a red dot in the center. For more information about the soil types of York Region & Southern Ontario visit
