摘要：

Biochar used in this study was prepared from wheat straw and enriched with 10% solutions of chemically pure salts: ammonium sulfate [(NH4)(2)SO4] and magnesium sulfate (MgSO4 7H(2)O). The aim of this study was to determine the growth response of Perennial ryegrass L. as well as identify changes in chemical and biological properties of sandy soil after the application of biochar. A significant increase in the amount of Perennial ryegrass L. biomass was determined after amending the soil with unenriched biochar and biochar enriched with (NH4)(2)SO4. The highest immobilization of available forms of Mg was observed for biochar enriched with (NH4)(2)SO4. The highest dehydrogenase activity was determined in the soil with biochar enriched with MgSO4 7H(2)O.
