Název v původním jazyce

The influence of fertilisation and crop rotation on soil microbial characteristics in the long-term field experiment

Popis výsledku v původním jazyce

Soils were sampled from the plots with four variants of fertilisation: Nil ? without fertilisation, NPK ? mineral fertilisation, FYM ? farmyard manure, FYM + NPK ? farmyard manure with mineral fertilisation, and two variants of crop rotation: field IV ?classical 9 years crop rotation, field B ? 2 years rotation alternative growing. Determination of urease, CFU of Azotobacter spp. and potential nitrogenase activity has been conducted for time period 1999?2004. The urease activity was positively affectedby manure fertilisation (FYM) and the combination of FYM + NPK. The statistically significantly highest counts of Azobacter spp. and the highest nitrogenase activity were determined on field B in variants FYM and FYM + NPK. The results show that there was a higher amount of accessible nitrogen present on field IV than on field B. This would explain the lower counts of Azotobacter spp. and therefore the lower nitrogenase activity.
