Effectiveness of different liming materials on some soil properties and yield of crops

Abstract

The stationary field experiment on the application of different types and doses of liming was started in Kupres plateu (1.184 m.a.s.l.), Bosnia and Herzegovina in the summer 2017. The aim of this three-year research was to determine the effectiveness of liming materials on changes in soil chemical properties and yield of cultivated crops. The used treatments were; control, crude dolomite from Rama, crude dolomite from Kupres, and commercial burnt lime; each applied at lower and higher dosages of 7 and 15 t/ha, respectively. Application of lime materials resulted in desirable reduction in soil acidity, and changes in the soil chemical complex with an increase of exchangeable Ca2+ after limestone application and increase of exchangeable Mg2+ after dolomite application. Commercial burnt lime (BLP) proved to be most effective, followed by crude dolomite Rama (CDR), while crude dolomite Kupres (CDK) proved to be the least effective. All cultivated crops (silage corn > triticale > spring barley) responded positively to the applied lime materials. In terms of investment and yields achieved, silage corn proved to be the most economical.
