Strategy of nitrogen fertilization in Slovene growing conditions is determined in the first place by our climatic and soil characteristics. Relatively high air temperature and abundant precipitation quantity (800 to 1600 mm in the most parts of the country) are two main characteristics of our climate. Abundant precipitation during the growth period in many cases exceeds the need of the plants as well as soil capacity for water. Especially in the areas where drinking water is collected, the soil is shallow ( 30 cm), therefore a large part of precipitation is drained during the growing period as well, which consequently pollute underground water with nitrates. Large areas covered with forests (52 %) and with permanent grasslands (30 %) diminish the effect of nitrogen leaking. The excess of precipitation and fast underground water streams protect the water from pollution as well. These are the reasons for which the nitrogen rate has to be divided into several parts. For better allotment of nitrogen, different new methods are proposed. They still have to be adopted to our conditions and to be used more often in praxis.
