Full explanation
Sod-podzolic profile: A1 (sod-humus 5–15 cm, 1.5–3% humus) → A2 (eluvial, leached, whitish 10–30 cm, pH 4.0–4.8) → B (illuvial, Fe/Al accumulation, red-brown 20–50 cm) → C (parent material, often moraine sands). In Ukraine: Rivne, Zhytomyr, Volyn, Lviv, northern Chernihiv oblasts. CEC 5–15 cmol(+)/kg (3–5× lower than chernozems). Farmer challenges: (1) low pH locks P and micronutrients, plus toxic Al³⁺; (2) low buffering — seasonal pH swings; (3) fast NPK leaching under high rainfall; (4) low humus — poor water-holding. Crops suited to unmodified podzol: rye, oats, potato, flax, lupin, clover, timothy, forage sorrel — acid-tolerant. Reclamation: liming (CaCO₃ dolomite) 4–8 t/ha worked in with a chisel plough. April 2026 land price after moratorium lift: USD 800–1,500/ha (versus USD 2,500–4,500/ha for chernozems).
