“…This may be due to the specific soil structure formation in NT soils [2]. However, most of the authors found higher SWC in no-till soils [2,4,28,29]. Water content, measured in stubble soils were higher than soil under crops, confirming the fact, that stubble phase plays important role in water preservation.…”

“…Present experiences reveal that at extreme weather conditions the planned depth of the loose layer may fulfil, but the size and distribution of the soil crumbs influenced by tillage induced biological activity, fall behind the optimum [9] and earthworm abundance decreases [10]. Relevant publications stated the most important findings in the role of the earthworms and outlined their importance in soil biological activity and the ecosystem services [4,11,12]. Authors referred to the quality of habitat, e.g., soil looseness or structure, temperature, water content, shading of surface, and supplying with food material [13,14].…”

“…However, the environmental condition of the soil is directly or indirectly affected by soil tillage [2,3]. The adverse effect of ploughing on soil condition is known from the literature [4,5], where authors frequently report negative impacts on deteriorated soil [6,7]. In spite of this, extreme weather modifies the soil tillage objectives [8].…”

“…Authors referred to the quality of habitat, e.g., soil looseness or structure, temperature, water content, shading of surface, and supplying with food material [13,14]. Evaluation of the relationships among tillage, soil condition, and earthworm abundance has been widely published [4,10,11,14,15], but it is needed to highlight that year weather effects in long-term experiments on their habitat required more knowledge.…”

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.

“…However, in our study, soil organic carbon was mainly stored in soil aggregates of 0.25-1 and <0.25 mm size ranges, and high level of biochar (20 or 40 t•ha −1 ) significantly increased the total organic carbon of these two fractions for each nitrogen treatment. This might be because in this experiment, conventional tillage was frequently carried out by mechanical tillage and caused breakage of soil large aggregates (>5 and 2-5 mm), thus they became easily attacked by microorganism, resulting in accelerating mineralization of SOM, and the retention of SOM was unfavorable [30]. However, through the action of stabilizing force, biochar combined with soil minerals to form aggregates, whose physical protection could reduce the decomposition of soil organic carbon in aggregates of 1-2, 0.25-1 and <0.25 mm size ranges by microorganism.…”

Reduction of soil fertility and production efficiency resulting from excessive application of chemical fertilizers is universal in rapeseed-growing fields. The main objective of our study was to assess the effects of biochar combined with nitrogen fertilizer reduction on soil aggregate stability and rapeseed yield and to identify the relationship between yield and soil aggregate stability. A two-factor field experiment (2017–2019) was conducted with biochar (0 (C0), 10 (C10), 20 (C20) and 40 t·ha−1 (C40)) and nitrogen fertilizer (180 (N100), 144 (N80) and 108 kg N·ha−1 (N60)). Experimental results indicated that under N100 and N80 treatments, C10 significantly increased the macro-aggregates (R0.25), mean weight diameter (MWD) and geometric mean diameter (GMD) of soil water stable aggregate by 14.28%–15.85%, 14.88%–17.08% and 36.26%–42.22%, respectively, compared with C0. Besides, the overall difference of the soil water-stable aggregate content in 2–5 mm size range among nitrogen treatments was significant under the application of C10, which increased by 17.04%–33.04% compared with C0. Total organic carbon (TOC) in R0.25 of soil mechanical-stable aggregates was basically all increased after biochar application, especially in 0.25–1 mm and 1–2 mm aggregates, and had an increasing trend with biochar increase. C10 significantly increased rapeseed yield by 22.08%–45.65% in 2019, compared with C0. However, the reduction of nitrogen fertilizer reduced the two-year average rapeseed yield, which decreased by 11.67%–31.67% compared with N100. The highest yield of rapeseed was obtained by N100C10 in two consecutive years, which had no statistical difference with N80C10. However, the two-year yields of N80C10 were all higher than those of N100C0 with increase rate of 16.11%, and which would reduce 35.43% nitrogen fertilizer in the case of small yield difference, compared with the highest yield (2.67 t·ha−1) calculated by multi-dimensional nonlinear regression models. The regression analysis indicated R0.25, MWD and GMD had the strong positive associations with rapeseed yield, whereas percentage of aggregate destruction (PAD0.25) had a significant negative correlation with rapeseed yield. This study suggests that the application of biochar into upland purple soil could improve soil structure, increase the content of TOC in macro-aggregates under nitrogen fertilizer reduction as well as replace part of nitrogen fertilizer to achieve relatively high rapeseed yield.

The Eurasian woodcock prefers habitats where its main prey, earthworms, can be found in higher densities. Although they are forest‐dwelling birds, they regularly visit pastures and natural grasslands at night, where earthworm abundance is generally higher. However, there is little information on fine‐scale habitat use in relation to variation in habitat characteristics and prey availability, particularly beyond the breeding season. In our study, we investigated if the nocturnal occurrence of woodcocks during migratory stopover periods differed between two neighbouring fields, or management units, with similar vegetation structure, and if within‐field variation in the spatial patterns of woodcock sightings were associated with fine‐scale earthworm densities and soil parameters. Specifically, we used GPS tracking data of two tagged woodcocks and direct observation data to study patterns of occurrence of birds in a mixed forest‐pasture landscape in Hungary during pre‐ and post‐breeding periods. We compared these patterns with fine‐scale soil characteristics and earthworm abundance, acquired by field sampling. We found that the field with higher earthworm abundance was visited by woodcocks more frequently, and this correlation was similarly observed at the intra‐field level. Our results demonstrate that woodcocks select foraging sites with higher earthworm densities at multiple spatial scales, both between fields (coarse scale), and within fields (fine‐scale). Considering that woodcocks tended to return to the same field to forage at night, the strong associations between occupancy and resources provide a basis for developing habitat management strategies at the field level for conservation. As earthworm densities and soil parameters are good indicators of woodcock foraging habitat, measuring those variables, at least at a coarse scale, could aid in predicting important habitats for the species across the landscape.
