Effect of conservation soil tillage and nitrogen fertilization on selected soil properties and crop productivity

Conservation soil tillage practise is different and specific for every European country mainly because of different agroecological conditions, different acceptance of new scientific approaches and technological innovations, and of course because of different approaches to soil tillage systems. Stationary field experiment was established in 2009 at two experimental stations on two different soil types in eastern Croatia. The main aim of this study, which was conducted under different agroecological conditions, was to test the effects of different tillage systems on some physical soil properties along with testing different nitrogen fertilization rates on productivity of maize and winter wheat crops. All main investigated soil parameters (bulk density, penetration resistance) and indicators of crop productivity (crop residues, crop biomass, yield components and yields) were highly influenced by agroecological conditions (mainly weather conditions and soil type).
