Effect of weather conditions and use of fertilizers on crop and soil mineral nitrogen content in years 1999-2000 during field experiment IOSDV/Tartu

Teesalu, T. | Leedu, E. (Estonian Agricultural Univ., Tartu (Estonia). Dept. of Soil Science and Agrochemistry)

The field experiment of IOSDV (set up in Tartu in 1989) with application of mineral nitrogen fertilizer in combination with different forms of organic fertilizer (manure, straw) during 2 years has led to changes in mineral nitrogen level depending on fertilization regime used. Crop rotation was the following: potato-spring-wheat-spring-barley. The weather conditions during the period of the study were rather different and it appeared that weather conditions are more important factors in determining mineral nitrogen content and crop yields than applying fertilizers.
