“…Nevertheless, high temperatures reduce the SWC (the loadings are relatively high, especially at 3 and 6 passes) and CO 2 emissions in the summer period. These results are consistent with those of previous works (Bogunovic et al, ; Tóth et al, ). Overall, vineyard management modifies soil properties and wine characteristics.…”

“…Our results are similar to these results, indicating that vegetation and cover crops have an impact on CO 2 emissions. Mulch and dead plants may be the reason for high CO 2 emissions in no‐tilled soils due to the high availability of carbon and the consequent microbiological activity, as observed in other works (e.g., Bilandžija et al, ; Tóth et al, ).…”

“…Tillage destroys the soil macro‐aggregates, reducing the retention of carbon labile forms in newly formed crumbs. Tóth et al () investigated the seasonal variability of CO 2 fluxes in ploughed and no‐tilled soils and observed a higher CO 2 emission in ploughed plots compared with no‐tilled soils just after ploughing. Nevertheless, later during the season, no‐tilled soils have higher CO 2 emissions than ploughed soils.…”

Few works have been carried out on the coupled impacts of different management practices and tractor traffic on soil properties and degradation in vineyards, grape productivity and must quality. The influence of different tillage practices (conventional tillage—CT; grass coverage in a given year—INV‐GC; tillage in a given year—INV‐T) and continuous grass coverage (CGC) on bulk density (BD), soil water content (SWC), CO2 emissions, grape yield and must quality have been investigated in a vineyard in Zagreb, Croatia. During 2017, soil properties were analysed in the 0–10 cm and 10–20 cm layers after 3, 6 and 11 tractor traffic passes. The results showed that tractor traffic increased the BD in the CGC, INV‐GC and INV‐T treatments. The BD at the 0–10 cm and 10–20 cm depths was significantly higher in CGC than in CT. During the wet year of 2017, CT and INV‐T had significantly higher SWCs than did CGC and INV‐GC. The CO2 emissions under different management practices were INV‐T (120.3 CO2 ha−1 yr−1) > CGC (111.4 CO2 ha−1 yr−1) > INV‐GC (71.7 CO2 ha−1 yr−1) > CT (51.5 kg CO2 ha−1 yr−1). The effects of soil management on must quality and grape composition measurements were also detected. Grape yield was as follows: CT (5.37 kg vine−1) > INV‐GC (4.43 kg vine−1) > CGC (4.06 kg vine−1) > INV‐T (3.87 kg vine−1). Treatments had a significant impact only on pruning weight, pH value and free amino nitrogen (FAN), whereas no significant differences were found in the cluster number per vine, mean cluster weight, sugar content and titratable acids.

“…The continuing increase in atmospheric concentration of greenhouse gases, especially carbon dioxide (CO 2 ), nitrous oxide (N 2 O), and methane (CH 4 ) can result in unforeseeable long-term effects on ecosystems as a feedback with climate change [21][22][23][24]. Terrestrial ecosystems currently act as a net sink of anthropogenic carbon emission, the soil itself storing 290 times larger amount of carbon than the 2009 global anthropogenic emissions [25].…”

Recent studies on using soil enhancer material, such as biochar, provide varying results from a soil hydrological and chemical perspective. Therefore, research focusing on soil-biochar-plant interactions is still necessary to enhance our knowledge on complex effects of biochar on soil characteristics. The present study investigated the changes in soil water content (SWC) and soil respiration (belowground CO2 production) over time during the growth of Capsicum annuum (pepper) in pot experiments. Concurrently, we investigated the influence of grain husk biochar with the amount of 0, 0.5%, 2.5%, and 5.0% (by weight) added to silt loam soil. Pepper plants were grown under natural environmental conditions to better represent field conditions, and additional irrigation was applied. SWC among treatments showed minor changes to precipitation during the beginning of the study while plants were in the growing phase. The highest water holding throughout the experiment was observed in the case of BC5.0. CO2 production increased in biochar amended soils during the first few days of the experiments; while the overall cumulative CO2 production was the highest in control and the lowest in BC2.5 treatments. We used the HYDRUS 1D soil hydrological model to simulate changes in SWC, using the control treatment without biochar as a reference data source for model calibration. The simulated SWC dynamics fitted well the measured ones in all treatments. Therefore, the HYDRUS 1D can be an exceptionally valuable tool to predict the hydrological response of different amount of biochar addition to silt loam soil including plant growth.

“…The research area covers 5.5 ha. The terrain is flat, with a soil of a clay-loam texture, Endocalcic Chernozems, loamic [20], a humus content of 3.12%; the sand, silt, and clay contents of the top 20 cm layer are 10%, 54%, and 36%, respectively [21]. The soil has a slightly acidic reaction pH (H 2 O) of 6.2 and pH (KCl) of 5.1 when all treatments and depths are considered.…”

Long Term Effects of Ploughing and Conservation Tillage Methods on Earthworm Abundance and Crumb Ratio

In addition to the dry (D) and rainy (R) seasons, a combination of the two i.e., rainy-dry (RD) and dry-rainy (DR), can also be observed in one year. The effects of the dry (D) and rainy (R) on soil are known, hence we hypothesized that the effects of the rainy-dry (RD) and dry-rainy (DR) periods on soil may differ from the former assessments. The aim of the study is to investigate the effect of six tillage treatments (ploughing—P, disk tillage—DT, loosening—L, tine tillage (a deeper—T and a shallower—ST) and no-till—NT) on earthworm abundance and crumb ratio during a long-term research (16 years) on Chernozems. The results related to the four year-groups (D, R, RD, and DR) with different residue cover. Seven degrees of cover ratio (between 12.5% and 62.5%) were selected on stubbles. Higher cover ratio (≥52.5%) improved water conservation, increased earthworm abundance (31 and 41 ind m–2) and crumb (78 and 82%) ratio (p < 0.001). R year came first in the rank of water content and earthworm abundance and DR proved to be more favorable for crumb formation. Considering the rank of soil tillage treatments, ST takes first place in evaluation of soil water content (SWC) and crumb ratio, and NT for earthworm abundance.
