Four readings taken before a single line is drawn
Every plot is walked and measured in September, while the ground is still dry. These four readings come from a 0.42 ha plot in Kyiv oblast and set the depth of every drain, terrace and root ball we install.
- Soil profile
- 0 to 0.35 m cultivated loam, sandy loam to 0.95 m, then dense grey clay to 2.1 m. Percolation 12 mm/h in the upper layer, below 2 mm/h under 1.0 m.
- Slope
- 1.8% fall to the south-east across 46 m, with terrace breaks at 0.9 m and 1.4 m. Surface run-off collects along the western boundary.
- Modelled water table
- Peak −0.55 m in March, low −1.65 m in August, modelled from three piezometers read over 14 months. Design level for drainage: −0.70 m.
- Frost zone
- 0.90 m design frost depth for Kyiv oblast. Footings, retaining walls and buried irrigation lines are set below it.
