Sažetak
Possible agricultural utilization of four different processed slaughterhouse waste composts and meat powder was examined in a field experiment in 2002-2006. The trial was set up with different crops on a calcareous sandy soil weakly supplied with N, P and K. The site was prone to drought. Composts were applied once at 5 levels (0, 25, 50, 100 and 200 t ha-1 fresh compost and 0, 2.5, 5, 10 and 20 t ha-1 meet powder) in 4 replications. Extreme doses (100 and 200 t ha-1) of immature and semi-mature compost combined with dry weather in 2002 and 2003 caused yield depression. Residual effects of composts were pronounced. In normal years the yield increased threefold compared to control. Differences were significant in the case of stronger composts even in 2006, in the 4th and 5th experimental years.
