Abstract | The purpose of this study was to measure the effects of plant growth on soil microbial biomass C (C-mic) and soil enzyme activities. In a pot experiment using spring barley and sugar beet, we investigated the response of C-mic, hot water extractable C and N fractions (C-hwe, N-hwe), and enzyme activities involved in C, N and P cycling in a loess-derived Chernozem from Bad Lauchstadt (Central Germany). The study site has been receiving the same fertilisation treatments for 100 years. The soil originated from plots fertilised with 15 t ha(-1) farmyard manure (FYM) year(-1) + mineral fertiliser (NPK), or 15 t ha(-1) FYM year(-1), or NPK or from an unfertilised control. Pots were sampled monthly, and alkaline phosphatase- (AP), beta-glucosidase- and protease-activities were analysed. At the beginning and the end of study, levels of C-mic, C-hwe and N-hwe were also measured. All three enzyme activities and C-mic were significantly and positively correlated with C-org and C-hwe. Results suggest that the enzyme activities measured originated mostly from microorganisms and that C-hwe is an important C source for soil microorganisms. beta-Glucosidase and AP activities were higher in summer months than at other times. In contrast, protease activity changed only slightly during the growing period. |
