EFFECT OF BIO-ORGANIC FERTILIZERS ON SEASONAL CHANGES OF INORGANIC NITROGEN FORMS IN THE SOIL UNDER WINTER WHEAT

Abstract

In a field stationary experiment was during growing seasons 2007/2008 and 2008/2009 investigated the effect of bio-organic fertilizers Condit Mineral and Condit Eco on the dynamics of inorganic nitrogen in the soil under winter wheat. The results of our experiment confirmed the greater dependence on the dynamics of inorganic nitrogen in the soil had climate conditions during the growing season than the applied fertilizers. Differences between fertilized variants were statistically no-significant. The highest contents of inorganic nitrogen were in the autumn Condit Mineral fertilizer application.
