“…Одним із найкращих опосередкованих показників рециркуляції органічної речовини (біологічної активності ґрунту) є інтенсивність його дихання (виділення СО2), яка напряму залежить від життєдіяльності аеробної біоти (Gray et al, 1971). Сучасними дослідженнями встановлено, що емісія СО2 за рахунок дихання ґрунту є чи не одним із найпотужніших джерел збільшення концентрації вуглекислоти в повітрі (Gonzales-Ubierna et al, 2015). За окремими підрахунками, обсяг втраченого з ґрунту за рахунок його дихання вуглецю за період від 1850-х років до сьогодення становить близько 136 (+/-55) млрд тон (Lal et al, 1998).…”

The article is devoted to study of the biological activity of soil under sweet corn crops depending on tillage depth, mineral fertilizers application rate with drip irrigation in the soil-ecological conditions of the Dry Steppe Zone of Ukraine. The plan of the experiment foresaw study of such factors: A -tillage depth (moldboard plowing on 20-22 and 28-30 cm); B -mineral fertilizers application rate (no fertilizers, N60P60, N120P120); C -plants density (35, 50, 65, 80 plants ha -1 ). We used water of the Ingulets irrigation system for irrigation. The water belongs to II quality class by agronomical criteria of the DSTU 2730-94 and its suitability for irrigation is limited. We studied the soil biological activity on variants with 65 plants ha -1 by the indicies of its respiration rate (method of V.I. Shtatnov) and linen decomposition degree ("application" method). At the same time we have made monitoring of the soil meliorative state depending on the moldboard plowing depth by the toxic salts content, anionic-cationic composition of the aqueous soil extract. The results of the laboratory-field experiments prove that the moldboard plowing depth , mineral fertilizers application rates and soil meliorative state have an influence on its biological activity. The maximum respiration rate, which is used to characterize an activity of the aerobic microflora of the upper soil layers, was at moldboard plowing on depth of 20-22 cm at non-fertilized experimental variant -250.0 mg СО2/m 2 ×hour. Increase of the tillage depth and mineral fertilizers application rate significantly decreased carbonic acid emission to the athmosphere, which was the minimum of 178.3 mg СО2/m 2 ×h. The maximum linen decomposition degree, which is used to characterize an activity of the cellulose-decomposing soil microflora, was at moldboard plowing depth of 28-30 cm at non-fertilized experimental variant -58.3%. The tillage depth changed cellulose-decomposing soil microflora activity insignificantly. Mineral fertilizers application at the maximum rate of N120P120 decreased cellulose-decomposing soil biota activity 1.7 times comparatively to non-fertilized variant. Higher toxic salts concentration (at 0.006-0.019 %), sodium ions content (at 0.15-0.38 mg-eq/100 g of soil) in the 0-50 cm layer led to decrease of the soil biological activity. We consider, that the best from the agroecological point of view is the variant with moldboard plowing depth of 28-30 cm, mineral fertilizers application rate N120P120.

“…Sewage sludge is used as a fertilizer. These sources contain a large amount of nutrients, which can enhance conditions for plants' growth, but also can increase the CO 2 emission from soils (e.g., Carmo et al, 2014;Dhanker et al, 2021;Fernández-Luqueño et al, 2009;González-Ubierna et al, 2015;Lloret et al, 2016;Paramasivam et al, 2008;Paudel et al, 2018;Sheppard et al, 2005;Yerli et al, 2022). In addition, it has been found that these sources also include variety of micropollutants including the human and veterinary pharmaceuticals that can contaminate soils and plants (e.g., Carter et al, 2019;Grabic et al, 2022;Ivanová et al, 2018;Klement et al, 2020;Kodešová et al, 2019a, b;Picó et al, 2020) and can also stimulate the CO 2 emission from soils (e.g., Fér et al 2020).…”

“…Despite that these soil amendments can have a significant impact on the CO 2 emission from soils, their actual effect on measured values has not been fully revealed. It has been found that the CO 2 emission increases with the increasing dose of a sewage sludge (Dhanker et al, 2021;Fernández-Luqueño et al, 2009), or that the impact of a sludge from different resources or resulted from different stabilization treatments on the CO 2 emission can differ (Carmo et al, 2014;Fernández-Luqueño et al, 2009;González-Ubierna et al, 2015). In addition, Fernández-Luqueño et al (2009) showed that the emission of CO 2 from sludge amended soils can be also affected by plants and this effect depends on a phenological stage of the plants.…”

The goal of this study was to evaluate the effect of products from a municipal wastewater treatment plant on the H2O and CO2 effluxes from two soils. The net H2O and CO2 effluxes were measured at the surface of nine beds with two different soils (Cambisol and Arenosol) and two crops (maize or vegetables). Soils in some beds were amended with stabilized sewage sludge (bed with Cambisol and maize) or composted sewage sludge (two beds with Cambisol and both crops) or were irrigated with treated wastewater (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). Remaining beds were irrigated with tap water (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). While stabilized and composted sewage sludge positively affected the CO2 emission, the effect of treated wastewater was not confirmed. Different treatments had negligible effect on the water efflux, which was mainly affected by the plant canopy that influence the temperature of the soil surface. Statistical analyses showed that trends of the CO2 efflux with respect to various scenarios measured on different days changed during the season. No significant correlations were found between the average H2O and CO2 effluxes and measured soil properties.

“…No tillage can improve the SOC concentration in the surface layer [ 13 ]; however, it is still controversial whether the SOC concentration in the deeper soil layers will be affected by long-term tillage [ 14 , 15 ]. The results of a twenty-two-year tillage experiment showed that the SOC concentration under no tillage at a 0–20 cm depth increased by 30% compared with that under plow tillage [ 16 ].…”

Scientific management of the soil organic carbon (SOC) pool, e.g., through a reasonable tillage system, is a potential way to mitigate global climate change. There is scarce information about the effect of tillage during the summer fallow period on the SOC pool in rainfed winter-wheat fields. The present study was designed to evaluate the effects of tillage practices, i.e., plow tillage (PTF), subsoiling (STF) and no tillage (NTF), during the summer fallow period on SOC sequestration in winter-wheat fields in the rainfed area of the eastern Loess Plateau of China. The SOC, mineral-associated organic carbon (MOC), permanganate-oxidizable organic carbon (POxC) and particulate organic carbon (POC) concentrations were determined after four years of tillage implementation during the summer fallow period. Our results showed that in comparison to the adoption of NTF, the adoption of STF significantly increased POxC, POC and MOC concentrations by 56.6–111.2%, 45.7–118.7% and 26.2–29.4%, respectively, at the 10–20 and 30–40 cm soil depths before sowing (P < 0.05). The POxC and MOC concentrations under STF at depths of 0–10, 10–20, 20–30 and 30–50 cm were significantly greater than those under PTF and NTF after harvesting (P < 0.05). In addition, the SOC concentration and SOC stock under STF were significantly greater than those under NTF at the 0–10, 10–20, 20–30 and 30–40 cm soil depths before sowing and after harvesting (P < 0.05). Furthermore, in comparison to PTF and NTF, STF resulted in significantly higher SOC stocks by 12.0–25.3% and 7.1–19.2% than PTF and NTF, respectively, in the 0–10, 0–20, 0–30, 0–40 and 0–50 cm soil profiles at harvesting (P < 0.05). In summary, the adoption of STF could be beneficial to the management of the SOC pool in the 0–50 cm soil profile in the rainfed area of winter-wheat on the Loess Plateau of China.
