SZULC, P. and J. BOCIANOWSKI, 2013. Monitoring of biogenic element concentrations in drainage water of the production field. Bulg. J. Agric. Sci., 19: 472-478
Studies on the monitoring of biogenic element content concentrations in drainage water were carried out on a production field in 2009-2010 belonging to the Experimental and Didactic Station of the Poznan University of Life Sciences, with a branch in Swadzim. During the two years of the research, it was found that the amount of N-NO3, P, K, Mg, Ca, and the salinity of drainage water from the production field depended on the time when the water was collected for analysis.
