Sažetak
Acid soils are widespread in Eastern Croatia. In general, liming of these soils is a usual recommnedation for their improvement. Five experiments have been conducted under field conditions during the past 25 years with purpose of exploring this problem. Three experiments were conducted from 1980 to 2000. They included liming with hydrated lime up to 10 t/ha and calcite up to 32 t/ha. In general, maize, soybean and barley grain yields increased due to liming by more than 10% or less than 10%, while wheat showed no response to lime application. Also, the effects of liming differed depending on the soil characteristics and the year of testing. Liming with carbocalk (sugar factory waste with about 37% CaO) was applied in three experiments. Depending on the experiment, the yield increases due to carbocalk application (15, 30 and 60 t/ha) were 23%, 100% and 43%, respectively.
