Liming and fertilization impact on nutrient status in acid soil
The effect of liming and different rates of mineral fertilizers upon the changes in the soil chemical properties were monitored on two sites in the eastern Croatia. After liming (10 t ha-1 carbocalc with total Ca content 344 g kg-1) the plots were fertilized for maize and in second year for winter wheat with three different nutrient amounts. Liming increased base saturation level and soil pH raised for approximately 1.2 pH units while hydrolytic acidity were decreased for 1.3 cmol (+) kg-1. Liming also significantly increased phosphorus availability for 17.1 mg kg-1. As a result of mineral fertilization nutrients availability raised for 25 mg P2O5 kg-1 and 50 mg K2O kg-1 at NPK treatment and for 54 mg P2O5 kg-1 and 70 mg K2O kg-1 at doubled mineral fertilization treatment, respectively. Results indicated that the effects of low liming rates in intensive crop production were short termed implying that more frequent or higher lime application is necessary in order to improve soil chemical properties and increase crop yields.
