“…A SW has a negative correlation with the labile fractions of carbon (CWEOC and HWEOC), but A LW has a negative correlation with non-labile carbon. This corresponds to findings of the authors that larger aggregates are richer in organic matter [35,90]; however, they are not the only labile components that are dominant. It is also true that smaller aggregates are poorer in organic carbon [91], though this does not have to be only the carbon of humus substances but also otherwise-stabilised organic substances.…”

Soil structure (SS) plays an important role in relation to climatic change, with the most important task the decreasing of CO2 in the atmosphere by carbon sequestration in the soil and the prevention of floods by better water infiltration into the soil. However, the evaluation of its condition is very different because of the various parameters and their inappropriate uses. The aim of this study was to determine the responses of the parameters of SS on the soil type and tillage system as the most important factors that influence it through changes in the soil organic matter and soil texture. The soil factor, which was represented by seven soil types (EF, Eutric Fluvisol; MF, Mollic Fluvisol; HC, Haplic Chernozem; HL, Haplic Luvisol; ER, Eutric Regosol; EG, Eutric Gleysol; DS, Distric Stagnosol), should be included in all evaluations of SS because of the specifics of each soil type. The tillage factor (shallow non-inversion-reduced, RT; deeper with inversion-conventional, CT) was chosen because of a high sensitivity of SS to soil disruption by cultivation, which represents high potential for the mitigation of climate change. The study included 126 sampling places in different parts of Slovakia on real farms (7 soil types × 3 localities × 3 crop rotations × 2 tillage systems × 2 soil depths). The soils were analysed for the aggregate fraction composition, particle size distribution, and parameters of organic carbon. The data of different parameters of SS were calculated and evaluated. The most sensitive parameter of the tested ones was the coefficient of structure (Kst), which manifested up to the level of the fractions of humus substances and indicated a better condition of SS in more productive soils than less productive soils. The coefficient of soil structure vulnerability (Kv) and mean weight diameter in water-resistant macroaggregates (MWDw) showed a worse condition of SS in the soils, which developed on Neogene sediments. A better condition of SS in RT was predicted particularly by the primary parameters (index of crusting, Ic; critical content of soil organic matter, St), and in CT, they were mainly the secondary parameters (Kst; water-resistant of soil aggregates, Kw). Overall, the suitability of the parameters of SS should be evaluated in relation to a specific soil type with its characteristics and should not be used universally.

“…The results of this study demonstrate that different straw-returning measures, including straw mulching, straw incorporation, and biochar application, have a significant impact on increasing soil carbon, nitrogen, phosphorus, and potassium levels (Tables 1 and 2). The direct effect of returning straw is to raise soil nutrient levels by introducing mineral nutrients and organic matter into the soil [29,30]. Straw and biochar, both rich in organic carbon, increase the organic matter content in the soil.…”

In order to investigate the comprehensive effects of straw returning on soil physical and chemical properties, as well as cotton growth in Jiangsu, China, and to determine suitable high-yield and efficient straw returning measures, this study implemented three different straw returning methods: straw mulching (SM), straw incorporation (SI), and straw biochar (BC), with no straw returning served as a control (CT). The study aimed to assess the impact of these straw-returning measures on soil nutrients, soil moisture content, soil water storage, and deficit status, as well as primary indicators of cotton growth. The findings revealed that the total available nutrient storage under SM, SI, and BC showed an increase of 11.93%, 11.15%, and 32.39%, respectively, compared to CT. Among these methods, BC demonstrated a significant enhancement in soil organic carbon content, available phosphorus, and available potassium. Furthermore, SM exhibited a considerable increase in soil moisture content across all layers (0–40 cm), resulting in an average water storage increase of 7.42 mm compared to CT. Consequently, this effectively reduced the soil water deficit during the cotton development period. Moreover, the height of cotton plants was increased by SM, SI, and BC, with SM promoting the greatest growth rate of up to 66.87%. SM resulted in an 11.17 cm increase in cotton plant height compared to CT. Additionally, SM contributed to higher chlorophyll content in leaves at the end of the growth period. Overall, the indicators suggest that straw mulching is particularly effective in enhancing soil moisture and nutrient distribution, especially during dry years, and has a positive impact on promoting cotton development. Based on the results, straw mulching emerges as a recommended straw-returning measure for improving soil quality and maximizing cotton production in the study area.

“…al., 1992;Hadas et al, 2004;Singh & Rengel, 2007). As expected, the decomposing residues and their metabolites are not only improved soil fertility, but increased soil water-holding capacity to improve soil quality and support crop productivity(Halder et al, 2023;Singh & Rengel, 2007). While N is the most critical essential nutrient required by the plants(Bernard & Habash, 2009;Wang et al, 2021); however, the FP, RD, and 125RD treatments did not consistently increase maize yield with N fertilization, indicating a lack of su cient N or partial availability of N to achieve the highest grain yield and e ciency for maize.…”

Nitrogen-use efficiency (NUE) of crops is critical for addressing global food security in response to climate change effects. The objective of our study was to evaluate the effects of N fertilization integrated with crop residue management to optimize NUE of crops. A replicated 2 x 4 split-plot experiment in randomized complete block design was conducted during the 2020–2022 on farmers’ fields at Bogura, Cumilla, and Mymensingh sites of Bangladesh. The main plots were two levels of crop residues (no residue, NR vs. 30% residue, CR) combined with sub-plots of four levels of N fertilizers (control, CL; farmers’ practice, FP; national recommended dose, RD, and 125% of RD, 125RD) on potato (Solanum tuberosum, L.), maize (Zea mays, L.), and rice (Oryza sativa, L.) systems. N fertilization when interacted with residue retention progressively increased crop yield. Residue alone contributed significantly to increase NUE of potato and maize by 9 and 6%, respectively. The NUE of rice increased significantly, while the NUE of maize decreased with N fertilization. The comparison of NUE models suggested that the nationally recommended N fertilization should be adjusted to 169, 152, 187, 92, and 112 kg/ha for potato, maize, Boro, Aus, and Aman rice, respectively. For potato and Aman rice, the SNMI showed better results, whereas for Boro, Aus, and maize, utilizing both NUE and SNMI provided maximum benefit from N management.
