“…During the years 1956-1999, springsown cereals dominated in the crop rotation and fodder rape and fodder beet were occasionally cultivated (Kirchmann et al, 1994), but since 2000, all plots except the bare fallows have been cropped with maize (Zea mays). To obtain a good estimate of the primary production in the different treatments, the average crop yield during 2000-2006 for each (Enwall et al, 2005(Enwall et al, , 2007.

“…Focus was on the nitrate-reducing and denitrifying bacteria as well as the AOB and AOA as model functional guilds, in addition to the total bacterial community in soil sampled in a long-term fertilizer field experiment established in 1956 in Sweden. The site provides a unique model system to relate microbial communities to ecosystem functioning, as the longterm effects related to fertilization have changed microbial activity and community composition (Enwall et al, 2005(Enwall et al, , 2007, in addition to differentiated soil properties and crop yield. We determined the size of the functional guilds and the total bacterial community by quantifying genes encoding some of the enzymes catalyzing reactions in the nitrogen cycle and 16S rRNA genes, respectively.…”

“…We determined the size of the functional guilds and the total bacterial community by quantifying genes encoding some of the enzymes catalyzing reactions in the nitrogen cycle and 16S rRNA genes, respectively. To explore the effect of correlation structure of community size and composition on ecosystem functions, the density data were subjected to an integrated statistical analysis using environmental factors and crop yield, together with the results on community composition and potential process rates previously reported from the same sampling occasion (Enwall et al, 2005(Enwall et al, , 2007.…”

The relative importance of size and composition of microbial communities in ecosystem functioning is poorly understood. Here, we investigated how community composition and size of selected functional guilds in the nitrogen cycle correlated with agroecosystem functioning, which was defined as microbial process rates, total crop yield and nitrogen content in the crop. Soil was sampled from a 50-year fertilizer trial and the treatments comprised unfertilized bare fallow, unfertilized with crop, and plots with crop fertilized with calcium nitrate, ammonium sulfate, solid cattle manure or sewage sludge. The size of the functional guilds and the total bacterial community were greatly affected by the fertilization regimes, especially by the sewage sludge and ammonium sulfate treatments. The community size results were combined with previously published data on the composition of the corresponding communities, potential ammonia oxidation, denitrification, basal and substrate-induced respiration rates, in addition to crop yield for an integrated analysis. It was found that differences in size, rather than composition, correlated with differences in process rates for the denitrifier and ammonia-oxidizing archaeal and total bacterial communities, whereas neither differences in size nor composition was correlated with differences in process rates for the ammonia-oxidizing bacterial community. In contrast, the composition of nitrate-reducing, denitrifying and total bacterial communities co-varied with primary production and both were strongly linked to soil properties.

Understanding the long‐term effects of manure applications on the soil microbial component in semiarid climates will be key to sustain essential processes that affect their productivity and soil health. In this paper, soil health indicators encompassed both selected chemical and biological indicators. From 2004 to 2009, solid dairy manure treatments were applied to plots at cumulative rates of 0, 134, and 237 dry Mg ha−1 (34–56 dry Mg ha−1 year−1) in a randomized complete block with three replicates. Soil samples were taken from each manure rate in the spring of 2020 at 0–15 and 15–30 cm. Eleven years after manure applications ceased, many of the soil chemical and biological indicators were different between the manure and control treatments. In general, soil organic carbon and biological indicators were significantly greater in the 134 and 237 Mg ha−1 treatments as compared to the 0 Mg ha−1 treatment.
