“…This corresponds with Wang et al (2013), who found that the organic fertilizer treatments improved soil aggregate stability and soil microbiological properties compared with unfertilized and mineral NPK treatments.…”

Agricultural practice often causes soil structure degradation and as a result it leads to changes in soil fertility and quality. The aim of this study was to compare soil aggregate stability (SAS) and soil organic matter (OM) quantity and quality in different systems of soil management. Three adjoining longterm experiments established on Chernozem were chosen; they were all set up in different years with different crop rotations and comparable fertilization treatments: control (without fertilization); NPK; manure; NPK + manure; N + manure; OM and NPK + OM. SAS was statistically significantly lower in the trial with the highest proportion of cereals in the crop rotation. Differences among the fertilization treatments were noticeable, but not significant; the lowest SAS was observed at treatments with the mineral NPK fertilization. Significant correlation was found out between SAS and C/N ratio (R = -0.571; P < 0.05) and between SAS and soil pH (R = 0.30; P < 0.05). Further, the individual trials differed in soil pH. A significant positive influence of the treatment NPK + manure was observed in the content of hot water-extractable carbon (C hwl ) and total soil organic carbon and nitrogen. The significant correlation between the 3000-2800/cm peak area of fourier transform infrared (FTIR) spectra and labile organic compounds in soil (C hwl ) was confirmed.

“…These results indicate a negative effect of mineral N application on the stability of soil aggregates and the possibility of elimination of this negative effect using the application of compost or organic-mineral substances. The results are consistent with the work of Wang et al (2013); Zhang et al (2016b); Bronick and Lal (2005). Soinne et al (2016) warn that the destruction of soil structure exhibiting a reduced stability of aggregates leads to a significant reduction of soil functions, such as changing soil moisture conditions and deterioration of soil infiltration capacity.…”

The stability of soil aggregates is one of the most important characteristics of the soil affecting the overall soil quality and its health. In locality Březová nad Svitavou, experiment to reveal the effect of nitrogen dose on the stability of soil aggregates of Rendzina soil was carried out. The aim was to detect changes in soil aggregate stability after 4 and 5 years from the beginning of the experiment. There were tested 7 variants, prepared in triplicate. The results revealed that the stability of soil aggregates decreases with increasing amounts of applied N. Effect of N application was not statistically significant in the fourth but in the fifth year of the experiment. The results also revealed a significant deterioration in the stability of soil aggregates in the fifth year compared to the fourth year of the experiment.

“…The microcosm method was validated to provide a good access for studying the effect of litter type on soil properties during the early stage of decomposition (Taylor and Parkinson 1988, Vargas et al 2006, Wang et al 2010. Since soil microbial biomass, enzyme activities, and DOC were suggested as early indicators of biological changes, and even important indicators of soil quality (Liang et al 1998, Hu et al 2006, Wang et al 2013, this study should provide some valuable information for the soil fertility management of the local pine plantations.…”

A laboratory microcosm experiment was conducted to evaluate the effects of the four single-species (Pinus tabulaeformis (Pt), Pinus radiata (Pr), Cercidiphyllum japonicum (Cj), and Ostryopsis davidiana (Od) litters from southwestern China and mixed pine-broadleaf (Pt + Cj, Pr + Cj, Pt + Od, Pr + Od) litters on soil microbial activities and dissolved organic carbon (DOC). Microcosms with the local typical soil and litterbags containing the eight litter types were incubated with 60% water field capacity for 84 days at 20°C. The results showed that the dynamics of soil microbial parameters and DOC were influenced by the litter types with different initial chemical quality. Due to their initial poor nutrient contents, the Pt and Pr litter treatments always showed lower soil microbial activities and DOC at each sampling compared with the Cj and Od litter treatments. However, compared with the single-species pine litter treatments, the inclusion of broadleaf Cj or Od litter into pine litter significantly increased soil microbial activities, and the concentrations of soil DOC during the whole incubation process. The current work thus provided a good implication for plantation management that it should be appropriate to consider Cj as an ameliorative species or retain Od in the pine plantations to improve soil conditions.
