Soil-introduced ashes affect mainly physical and chemical properties of soil, i.e. its reaction, acidity, amount of aluminium exchangeable, capacity of sorption complex and water absorbing power.
Addition of fly ash significantly enriched soil in exchangeable calcium and magnesium. During second and third year of the experiment it has been observed that the effect of brown coal ash presence tended to get lower.
Applied brown coal ash, despite using large quantities, did not contribute to abundance changes of metals: zinc, copper, nickel, lead and cobalt in soil and did not affect crop size, its structure and biometric features of cultivated plants.
