ABSTRACT
The objective of the pot trial carried out at the area of the Slovak University of Agriculture in Nitra was to determine the impact of dry pig manure produced on the sawdust bedding and sawdust litter on the level of nutrients’ mobility in the soil and sugar beet yield. The achieved results showed that one month after the sawdust and manure application to the soil, the contents of mobile nutrients (Nan, P, K, Ca, Mg) in soil were lower than in the control unfertilized treatment. The sawdust litter immobilized nutrients more considerably than manure. Four months after the manure application into soil, its immobilization effect was not evident. On the contrary, the manure increased the mobile nutrients content in soil. In the second year of experiment the immobilization effect of sawdust litter was proved even four months after its application into soil. The application of manure increased considerably the beet root yield. The maximum root yield was determined in the treatment where the highest dose of manure was applied. The minimum root yield was detected in the treatment where the highest dose of sawdust litter was applied.
