We studied the long-term effect (about 45 years) of farmyard manure, sewage sludge and compost application in two increments on organic carbon (C<sub>org</sub>), the amount (C<sub>mic</sub>) and activity of the microbial biomass (soil respiration, dehydrogenase activity), total N content and N delivery of soils as compared to manuring with mineral fertilizers. The application of both increments of compost and the high sewage sludge application rate resulted in an increase in C<sub>org</sub> while soils treated with both compost application rates and the high farmyard manure application rate showed a significant increase in C<sub>mic</sub>. C<sub>mic</sub>/C<sub>org</sub> ranged between 1.7 and 3.3. Dehydrogenase activity and soil respiration were the greatest in the soil with the highest compost and farmyard manure application rates. Total soil N content was significantly higher in both compost treatments and in the treatment with the high sewage sludge application rate. This was accompanied by the highest N uptake of ryegrass. &nbsp;

Abstract. Soil contamination by trace elements (TEs) is a major concern for sustainable land management. One potential source of excessive inputs of TEs into agricultural soils are organic amendments. Here, we use dynamic simulations carried out with the IDMM-ag model to describe observed trends of topsoil Zn, Cu, Pb and Cd concentrations in a long-term crop trial in Switzerland, where soils plots have been treated with differing organic amendments, particularly farmyard manure, sewage sludge and compost. IDMM-ag requires the definition of a parsimonious set of boundary conditions. The model adequately reproduced the metal EDTA-extractable concentrations in ZOFE when site-specific soil lateral mixing, due to mechanically ploughing of small plots, was introduced. Calibration of an additional metal input flux was necessary to fit the measured data, indicating that knowledge gaps in quantifying historical metal inputs can affect field-scale simulations even in a well-characterized field. Projections of soil metal content in the long-term showed that, under stable organic amendment application rates, Zn and Cu labile concentrations might pose toxicological hazard for the soil ecosystem, particularly in the sewage sludge-amended plots. The sewage sludge topsoil was characterized by some variability in the organic matter composition, potentially due to the applied sewage sludge quality, which might affect the metal lability: this effect should be accounted for in models. This study takes a step forward in assessing potential and limitations of the IDMM-ag model to predict TEs long-term dynamics in agricultural fields, paving the way to quantitative applications of TEs modelling at field and larger scales.

This study describes the long-term effects of different sewage sludge application rates on vegetative parameters, morphological characteristics, yield, and chemical properties of fruit and leaves of sour cherry (Prunus cerasusL.) cv. “Kütahya.” A three-year field experiment was set up in a completely randomized block design with six sewage sludge application rates (0.0, 2.5, 5.0, 7.5, 10.0 and 12.5 kg of dry matter per tree) and three replications. One-year-old Kütahya sour cherry trees grafted onPrunus mahalebrootstock were evaluated. In all application rates, sewage sludge altered vegetative growth parameters, morphological characteristics, and yield. The most effective application rate was 7.5 kg per tree, it increased cumulative yield more than twofold. The results obtained in this study demonstrate that application of sewage sludge to light-textured soil is an effective means for improvement of vegetative growth and yield, and that a single application of sewage sludge sustains its effects for at least 7 years.

A field experiment established in 1962 on a luvisol derived from loess was chosen to investigate the effect of long-term application of farmyard manure, compost and sewage sludge, respectively, in two increments on inorganic and organic S fractions in bulk soil. Compared with mineral fertilizer, the high application rates of the different organic fertilizers (10 t farmyard manure (FYM2), 29 t compost (COM2), 7.44 t sewage sludge (SS2)/ha/year, respectively), resulted in an increase of the total S content in the bulk soil: 220 mg/kg (FYM2), 298 mg/kg (COM2), 277 mg/kg soil (SS2) as compared to the control (MIN) with 158 mg/kg soil. The sum of water soluble plus adsorbed S was significantly higher in the treatments with the high amount of compost (17.9 mg/kg soil) and sewage sludge (16.4 mg/kg) soil as compared to all the other treatments (10.0 to 13.1 mg/kg soil). The treatments with the high amounts of organic manures contained lower contents of ester sulfate and higher contents of C-bonded S as compared to the treatments with the low amounts, and vice versa. &nbsp; &nbsp;

ABSTRACT The objective of this study was to explore the long-term effects of different organic and inorganic fertilizers on activity and composition of the denitrifying and total bacterial communities in arable soil. Soil from the following six treatments was analyzed in an experimental field site established in 1956: cattle manure, sewage sludge, Ca(NO3)2, (NH4)2SO4, and unfertilized and unfertilized bare fallow. All plots but the fallow were planted with corn. The activity was measured in terms of potential denitrification rate and basal soil respiration. The nosZ and narG genes were used as functional markers of the denitrifying community, and the composition was analyzed using denaturing gradient gel electrophoresis of nosZ and restriction fragment length polymorphism of narG, together with cloning and sequencing. A fingerprint of the total bacterial community was assessed by ribosomal intergenic spacer region analysis (RISA). The potential denitrification rates were higher in plots treated with organic fertilizer than in those with only mineral fertilizer. The basal soil respiration rates were positively correlated to soil carbon content, and the highest rates were found in the plots with the addition of sewage sludge. Fingerprints of the nosZ and narG genes, as well as the RISA, showed significant differences in the corresponding communities in the plots treated with (NH4)2SO4 and sewage sludge, which exhibited the lowest pH. In contrast, similar patterns were observed among the other four treatments, unfertilized plots with and without crops and the plots treated with Ca(NO3)2 or with manure. This study shows that the addition of different fertilizers affects both the activity and the composition of the denitrifying communities in arable soil on a long-term basis. However, the treatments in which the denitrifying and bacterial community composition differed the most did not correspond to treatments with the most different activities, showing that potential activity was uncoupled to community composition.

A continuous long-term field experiment (2008–2018) was conducted in Xinjiang, north-western China, to assess the impact of farmyard manure (FYM) and inorganic fertilisers on the sustainable biomass yield of sweet sorghum cultivar (Xingaoliang No. 3) and soil chemical properties. Seven treatments, associated with nitrogen (N), phosphorus (P), potassium (K), FYM, and their different combination, were compared with the control plot (CK). As a result, the treatments NP, PK, NK, NPK and NPKM significantly increased the average biomass yields by 30–48% over CK. The 12 t/ha FYM per year with NPK (NPKM) increased both the yield and total soluble solids (T<sub>SS</sub>) by 48% and 7.9%, respectively, while the 18 t/ha/year application rate of FYM had an adverse effect on yield. Stem T<sub>SS</sub>, soil available N and K for all treatments decreased while soil organic carbon, soil total salt and the available P for FYM applied treatments increased over the years. The soil pH stabilised at 7.8–8.2 at the end. In conclusion, the 12 t/ha/year of FYM is the most efficient rate for a single application or incorporation with inorganic fertilisers. A more reasonable application rate of N and K fertiliser to increase the yield and irrigation rate to reduce soil salt needs for further investigation.
