THE USAGE OF STATISTICAL METHODS FOR EVALUATION OF INORGANIC NITROGEN CONTENT IN SOIL

摘要

This paper shows the impacts of ago-technical arrangements oriented on the dynamics of inorganic nitrogen content. From the tilt practices, this effect described two methods of cultivation (medium depth ploughing-B1, shallow ploughing-B2) with tree variants of fertilization in two depths. The results of the analyzes confirmed that the average inorganic nitrogen content decreased as the depth increased and the date of soil sampling as a function of the growing season.
