“…Jacobs et al (2009) reported a result from Germany that after 37–40 years, TOC increased by 35%–50% under minimum tillage than under PT, which is very similar to our results. Approximately 20 km from our experimental area, Bankó et al (2021) analysed the effects of three farmyard manure (FYM) doses with and without ploughed‐in plant residues on the PT field. After four decades, the increase in TOC was only 9.57%–15.10% for the FYM input and 14.66%–26.20% for the residue management.…”

“…Amino‐N is a derivative of organic matter that provides N that is ready for use by microorganisms (Moore et al, 2019). Soil microbial activity is highly related to soil organic C and N. Several authors have concluded that the water‐extractable or amino‐N is a more sensitive measurement of the soil substrate and the impact of the tillage system which drives soil microbial activity (Bankó et al, 2021; Haney et al, 2012). Theoretically, an adequate amount of C and N stimulates the decomposition process, releasing high amounts of organic carbon and nutrients in the soil.…”

Conservation tillage (CT) is a ploughless tillage with a reduced number of operations, and its positive effect on soil functions and health is widely known. Multivariate analyses are required to choose indicators that adequately characterize the changes in soil health. However, there is little research on the comprehensive analysis of the full spectrum of soil physical, chemical and biological properties. Therefore, we examined 21 soil parameters in a long‐term CT experiment conducted in Hungary. Four pairs of similarly sized CT and conventional ploughing tillage (PT) plots were set up in 2003 on Luvisols. The soil samples were collected after 17 years. The total organic carbon (TOC) increased significantly in the 0–15 cm layer at CT sites compared to those in PT, indicating a total increase of 5.22 t ha−1 TOC stock. In addition, the increasing biological activity and improved soil structure were the most important processes at the CT sites. Furthermore, more complex humic substances with higher molecular weights are characteristic of water‐extractable organic matter (WEOM) as a result of CT. The potentially available nitrogen, phosphorus and potassium were also measured with a relatively high response ratio. Slowly changing parameters, such as cation exchange capacity and base saturation, are important soil physical and chemical parameters, but are not good indicators of the impact of tillage practices. Based on principal component analysis, we suggest the use of water‐extractable organic C, amino‐nitrogen, water‐stable aggregates, available P and K and photometric analysis of WEOM to identify the soil improving processes.

“…Hotwater extractable N is a useful predictor for tillage practices, N mineralization, and available N, providing recommendations on the optimum N dose that should be applied (Zhou et al, 2012). Also, according to Bankó et al (2021), HWC and HWN are correlated with SOC and TN. MBC was greater under NT at both Concord and Lincoln sites when compared to double disk, chisel, and moldboard plow (Table 1).…”

Agricultural management practices tend to influence soil structure stabilization, mediating many physical, chemical, and biological processes in soils. Therefore, understanding the long‐term effects of management practices on various soil health indicators is crucial to develop sustainable agricultural practices. This study aimed to assess the long‐term conventional and conservation tillage effects on soil physical (aggregates) and biochemical (soil organic carbon [SOC], enzymes, and microbial biomass) parameters under a range of tillage practices in a corn–soybean rotation in Nebraska. The experiment was conducted at two locations as follows: (1) Concord site (36 years) with the three treatments: no‐till (NT), disk, and moldboard plow; and (2) Lincoln site (40 years) with four tillage treatments: NT, double disk, chisel, and moldboard plow. Results showed that NT at both sites significantly increased SOC concentration by 24%–66% compared to moldboard plow. Similarly, double disk tillage increased SOC by 54% compared to the moldboard plow at the Lincoln site. Arylsulfatase, β‐glucosidase, hot‐ and cold‐water extractable carbon, microbial biomass carbon, and nitrogen concentrations significantly decreased with the increased tillage intensity at both sites. This implies that the NT increased these parameters compared to the disk and moldboard plow. However, aggregate size fraction 0.053–0.25 mm was the only parameter higher under moldboard plow (20.8%) than NT. Overall, the results from these long‐term studies indicate that NT, and to a lesser extent the reduced tillage practice of disk till, can improve soil health more than conventional tillage practices under a corn–soybean cropping system, suggesting the adoption of sustainable agricultural practices to improve soil health.

“…Soil organic matter has been used for many years as one of the major indicators of soil quality, given its important role in controlling soil chemistry as well as physical and biological processes [85]. However, it may take many decades to detect a change in the total soil organic C pool, given its slow rate of change [86]. Water-soluble and hot waterextractable C and N analyzed in this study are labile components of soil organic matter that could reflect early changes in soil-plant interactions [87].…”

“…Water-soluble fractions contain dissolved organic components almost similar to those measured directly in the soil solution using lysimeters and suction devices [88]. Hot water-extractable fractions consist of an easily decomposable pool of SOM, including microbial biomass, that serves as the source of energy and substrate to soil microorganisms, and its decomposition provides nutrients to plants [61,86]. This implies that labile fractions of SOM, especially those extracted with hot water, might be used as a proxy for soil microbial biomass and activity [28,61].…”

Long-Term Effects of Forest Plantation Species on Chemical Soil Properties in Southern Rwanda

Understanding the long-term effects of tree species on soil properties is crucial for the development of forest restoration policies in relation to the choice of species that meet both environmental and local livelihood needs. This study was performed in the Arboretum of Ruhande, Southern Rwanda, where monocultures of 148 deciduous and 56 conifer species have been established in 0.25 ha replicated plots from 1933 onwards. We investigated the effects of six exotic and two native tree species planted in monoculture plots and native species mixed within one self-regenerated plot on soil properties in two layers (0–5 cm and 5–10 cm depth). We measured general soil properties (pH, SOM, exchangeable base cations) and water-soluble C and N as a proxy for soil functioning. Changes in soil properties were observed in the upper soil layer for all tree species. Planting Eucalyptus species caused soil acidification, whereas soil exchangeable cations and pH were higher under native species (Entandrophragma excelsum and Polyschias fulva) and mixed native species. The effects of tree species were more pronounced for hot water-extractable C and N than for other soil properties. Their analyses could be used for detecting changes in soil functioning linked to vegetation types.
