Liming, fertilization and chemical properties of dystric cambisols

A field trial with liming and fertilization of Dystric Cambisol at Lika area in mountain part of Croatia was set up in 1998. The trial involved 12 different combinations of liming, mineral and organic fertilization in 4 replications. The crops included in the crop rotation are barley, potato, maize, rye and wheat. Two rates of limestone were applied (10 and 20 t ha-1). Marked acidity of the soil in this region is one of the main causes of poor soil fertility and relatively low yields of grown crops. Mineral and organic fertilizers very often are not applied in the correct manner, while liming, as the key soil-improvement measure, is generally not practiced. The differences in the yield according to the trial treatments point to the conclusion that liming, combined with organic and mineral fertilization had statistically significant positive influence on the correction of the excessive acidity of Dystric Cambisols as well as on the yield of the grown crops.
