“…Blake et al (2000) did not find any impact on total C during storage for air‐dried samples analysed first in 1959–1964, stored in a daylit room in lead‐sealed or waxed cork‐sealed glass bottles and re‐analysed in 1991. However, Włodarczyk et al (2014) found a storage effect on organic C concentration. Soil samples of different soil types were stored over 25 years in the Polish Bank of Soil under air‐dry conditions and compared with fresh soil samples taken from the same site in the year of analysis.…”

“…Stored and fresh soil samples were air-dried, rewetted and subsequently analysed for SOC and microbial biomass activity and resulted in unexpected fractions of microbial biomass that survived storage (about 20% with 47 years and 10% with 80 years of storage; De Nobili et al, 2006). We remark that this increased SOC concentration in freshly taken soil samples for both studies (De Nobili et al, 2006;Włodarczyk et al, 2014) is likely to be related to land use changes and natural C turnover that took place over decades in the resampled soils, but not necessarily due to storage conditions. However, in the current study, soil moisture content was $1 Vol.…”

Long‐term experiments (LTEs) have provided data to modellers and agronomists to investigate changes and dynamics of soil organic carbon (SOC) under different cropping systems. As treatment changes have occurred due to agricultural advancements, so too have analytical soil methods. This may lead to method bias over time, which could affect the robust interpretation of data and conclusions drawn. This study aims to quantify differences in SOC due to changes in dry combustion methods over time, using soil samples of a LTE established in 1963 that focuses on mineral and organic fertilizer management in the temperate zone of Northeast Germany. For this purpose, 1059 soil samples, collected between 1976 and 2008, have been analysed twice, once with their historical laboratory method right after sampling, and a second time in 2016 when all samples were analysed using the same elementary analyser. In 9 of 11 soil sampling campaigns, a paired t‐test provided evidence for significant differences in the historical SOC values when compared with the re‐analysed concentrations of the same LTE sample. In the sampling years 1988 and 2004, the historical analysis obtained about 0.9 g kg−1 lower SOC compared with the re‐analysed one. For 1990 and 1998, this difference was about 0.4 g kg−1. Correction factors, an approach often used to correct for different analytical techniques, could only be applied for 5 of 11 sampling campaigns to account for constant and proportional systematic method error. For this particular LTE, the interpretation of SOC changes due to agronomic management (here fertilization) deviates depending on the analytical method used, which may weaken the explanatory power of the historical data. We demonstrate that analytical method changes over time present one of many challenges in the interpretation of time series data of SOC dynamics. Therefore, LTE site managers need to ensure providing all necessary protocols and data in order to retrace method changes and if necessary recalculate SOC. Highlights A total of 1059 LTE soil samples taken between 1976 and 2008 were re‐analysed for SOC in 2016 Several methodological changes for SOC determination led to significant different SOC concentration in the same sample Interpretation and time series of LTE soil data suffer from consideration of analytical method changes and poor documentation of the same Soil archive establishment, thorough method protocols and diligent proficiency testing after soil method changes ameliorate the dilemma

“…1) suggests rapid oxygen uptake. In the anaerobic parts of the aggregates, following O 2 depletion, facultative anaerobes shift their metabolism and use NO 3 − as electron acceptors during denitrification (Włodarczyk et al 2014). The significant difference in the NH 4 + -N contents between the AP+ and AP− aggregates after 24 h of incubation may have been due to the intensive N assimilation associated with the rapid growth of microbial communities stimulated by apple pomace.…”

Apple pomace (AP) is an abundant waste causing environmental problems. Therefore, the aim of the study was to evaluate the impact of AP on soil and plant growth under optimum and limited water availability. Two laboratory experiments were conducted to evaluate the impact of AP on: (i) hydrophysical properties, respiration, and N transformations in soil aggregates and (ii) the growth of wheat and faba bean in soil with addition of AP under optimum and limited water availability. The soil respiration rate increased rapidly after the introduction of AP, and the effect was dependent on the aggregate size. The reduction of nitrate and the increase in ammonium content in response to the AP addition were more pronounced in the larger aggregates. Reduced growth of wheat was noted in the dry soil supplemented with AP. Faba bean maintained its unchanged rate of growth after the application of AP, irrespective of water availability. An increase in the chlorophyll content was observed in faba bean grown in the AP-enriched soil. The apple pomace reduced the water wetting rate and increased the repellency index but did not affect the tensile strength of the soil aggregates. Disposal of AP as a soil amendment affects many indicators of soil quality. The application of AP to the soil has an impact on respiration and N transformations in the soil aggregates; moreover, it differently influences the growth of spring wheat and faba bean.

“…The most clustered results of the first measurement, (AD soils in Figure 3 ), indicate that the storage of a soil in AD conditions somehow equalizes the influence of the soil origin (type) on the volatile fingerprint. The microbial activity of AD soil is practically zero; however, the microorganisms can still be reactivated [ 50 ].…”

The possibility of distinguishing different soil moisture levels by electronic nose (e-nose) was studied. Ten arable soils of various types were investigated. The measurements were performed for air-dry (AD) soils stored for one year, then moistened to field water capacity and finally dried within a period of 180 days. The volatile fingerprints changed during the course of drying. At the end of the drying cycle, the fingerprints were similar to those of the initial AD soils. Principal component analysis (PCA) and artificial neural network (ANN) analysis showed that e-nose results can be used to distinguish soil moisture. It was also shown that different soils can give different e-nose signals at the same moistures.
