The present study investigated the effects produced in the soil by municipal sewage
sludge and wood ash applied during the cultivation of Jerusalem artichoke. The impact of the
presence of applied the fertilizer materials on changes in soil and a macro- and microelements
contents were investigated. The comparative analyses took into account 3 factors; the first
factor - 4 levels of wood ash – 0; I–4.28; II–8.57; III–12.85 t ha-1, the second factor – 2 levels of
sewage sludge – 0; 1 – 30.3 t ha-1, the third factor – 2 varieties of Jerusalem artichoke (Helianthus
tuberosus L.) – Gigant, Albik. Application of the fertilisers did not resulted in significant change
in the total contents of phosphorus, potassium and magnesium in soil examined after Jerusalem
artichoke was harvested. Application of ash from coniferous trees, with high levels of calcium,
resulted in increased total contents of calcium in the soil. Fertilisation of the soil with ash from
coniferous trees or with sewage sludge, as well as cultivation of two varieties of Jerusalem
artichoke, resulted in a significant increase in the concentrations of cadmium and lead, and
produced no effects in the levels of nickel, zinc and copper identified in soil. The above findings,
and in particular the fact that the limit values were not exceeded, indicate the possibility of using
both sludge and biomass ash for fertilizing Jerusalem artichoke.
