      abstract = {Use of fertilizers keeps increasing on the global scale,  primarily because of
increased fertilizer use in developing  countries. In conditions of the global
economic crisis, the  portion of expenditures for mineral fertilization  increases
within the total price of main field  crops.
Nitrogen fertilization cannot be omitted because of  specific properties of
this macronutrients (migration down  the soil profile).
Low humus content was found in a large  number of soil samples taken on
the territory of the  Vojvodina Province. This calls for a more intensive  application
of organic fertilizers and restraint from the  practice of burning harvest residues.
Phosphorus and  potassium fertilization may be optimized if soil  analyses
show that the levels of these macronutrients are  above the optimum level (a
minimum of 15 mg/100 g of soil).  Length of period during which phosphorus and
potassium  fertilization will be omitted depends on the actual levels  of these
elements in the soil and crops grown.},
