“…In support, Álvaro-Fuentes et al (2008), who investigated tillage impact on CO 2 emissions from soils in a semiarid climate, attributed the observed large difference between tillage and no-tillage to differences in soil water availability. At humid sites high soil moisture favour high decomposition rates resulting in small differences between tilled and untilled soils, while large differences develop in arid climates with much lower soil water content (Fortin et al, 1996;Feizienė et al, 2011). This supports the idea that the soil response to tillage is affected by climate thresholds (Franzluebbers and Arshad, 1996).…”

“…The greatest soil CO 2 emission amongst the considered sites was 9125 g C-CO 2 m −2 yr −1 observed under tilled soils with barley in an arid area at Nesson Valley in western North Dakota, USA . The lowest soil CO 2 emission was 11 g CO 2 -C m −2 yr −1 observed under no-tillage wheat in the humid climate of Lithuania (Feizienė et al, 2011).…”

Abstract. The management of agroecosystems plays a crucial role in the global carbon cycle with soil tillage leading to known organic carbon redistributions within soils and changes in soil CO 2 emissions. Yet, discrepancies exist on the impact of tillage on soil CO 2 emissions and on the main soil and environmental controls. A meta-analysis was conducted using 46 peer-reviewed publications totaling 174 paired observations comparing CO 2 emissions over entire seasons or years from tilled and untilled soils across different climates, crop types and soil conditions with the objective of quantifying tillage impact on CO 2 emissions and assessing the main controls. On average, tilled soils emitted 21 % more CO 2 than untilled soils, which corresponded to a significant difference at P <0.05. The difference increased to 29 % in sandy soils from arid climates with low soil organic carbon content (SOC C < 1 %) and low soil moisture, but tillage had no impact on CO 2 fluxes in clayey soils with high background SOC C (> 3 %). Finally, nitrogen fertilization and crop residue management had little effect on the CO 2 responses of soils to no-tillage. These results suggest no-tillage is an effective mitigation measure of carbon dioxide losses from dry land soils. They emphasize the importance of including information on soil factors such as texture, aggregate stability and organic carbon content in global models of the carbon cycle.

“…It is known that agricultural practices play a significant role in production and consumption of greenhouse gas, specifically, CO 2 (Rastogi et al, 2002;Smith et al, 2008). Soil water content is consider as the most influential environmental factor controlling soil surface CO 2 fluxes (Lopes de Gerenyu et al, 2005;Feiziene et al, 2012). Soil net carbon exchange rates peaked at intermediate soil moisture and decreased under increasingly dry conditions (drought induced), but also decreased when soils became water saturated (van Straaten et al, 2009).…”

Little is known about the effects of modern soil management practices, especially no-tillage, on soil physical state, soil pore size distribution and soil water capacity after a long-time of successive application on different soil types. The investigations were performed in 2014 at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry in Central Lithuania's lowland on a sandy loam-textured Endocalcari-Epihypogleyic Cambisol (CMg-p-w-can) and at the Experimental Station of Aleksandras Stulginskis University on a silt loamtextured Endohypogleyic-Eutric Planosol (PLe-gln-w). The goals of this paper were a) to compare soil water capacity, soil pore-size distribution and CO 2 e-flux in Cambisol and Planosol, b) to evaluate the effect of long-term no-tillage application in combination with and without residue management on hydro-physical properties of soils with different genesis and c) to assess the suitability of such management practice for practical use. Regarding different soils genesis, the lower bulk density and higher total porosity were registered within 0-20 cm depth in Planosol than in Cambisol, while Cambisol was better aerated than Planosol due to a greater space of macropores. A risk of waterlogging condition may occur in Planosol due to a greater share of meso-and microporosity within 5-35 cm soil depth, compared to Cambisol. No-tillage application with crop residue returning was more suitable on Cambisol than on Planosol. This soil management system increased volumetric water content in the soil and CO 2 e-flux. No-tillage with residue removal on Cambisol conditioned soil CO 2 e-flux increase when volumetric soil water content ranged from 0.159 to 0.196 m 3 m -3 . When soil water content increased up to 0.220-0.250 m 3 m -3 , the e-flux peak was reached at which the further CO 2 e-flux sloped down. On Planosol, the soil CO 2 e-flux peak ranges were lower, i.e. approximately 0.170-0.200 m 3 m -3 . Long-term residue returning onto soil surface on Planosol acted as a physical obstruction inside mesopores in 5-10 cm and within macropores in 5-10 and 15-20 cm layers and, finally, causing clogging them. Increase of soil surface volumetric water content in Planosol caused a decrease in soil CO 2 e-flux.

“…Soil moisture is considered as the most influential environmental factor controlling soil surface CO 2 flux (Wiseman & Seiler 2004;Lopes de Gerenyu et al 2005;Regina & Alakukku 2010;Feizienė et al 2012). Soil moisture increase usually favours soil respiration activity, while under dry conditions soil CO 2 efflux is lower.…”

There have been few long-term field studies on greenhouse gases measurement in organic crop rotations under temperate climatic conditions. Little is known about the extent to which the share of legumes in a crop rotation of organic farming affects the potentials for CO 2 emission and soil organic carbon sequestration. The current study was aimed to investigate soil physicochemical state and soil net CO 2 exchange rate in diverse organic crop rotations with different crop species and proportions of legumes. Four 5-year duration crop rotations were investigated. The best soil sustainability of the arable layer was found in a crop rotation enriched with red clover (Trifolium pratense L.). This rotation resulted in the highest soil mesoporosity and the lowest microporosity, ensured the best supply of plant-available water and revealed high soil resistance to dry conditions. Red clover secured the highest soil organic C sequestration, caused the increase in reserves of total N and available K, and slackened the decrease of soil-available P sources. Red clover-based cropping system exhibited the highest soil net CO 2 exchange rate during five experimental years. The effect of crop rotation, consisting of phacelia (Phacelia tanacetifolia Benth.), peas (Pisum sativum L.) and yellow lupin (Lupinus luteus L.), on soil sustainability was weaker than the effect of rotation with red clover. Non-legume rotations, i.e. binary (two-crop) rotation and the crop rotation involving four spring and one winter species, can be regarded as miners of soil nutrient resources rather than contributors. These rotations did not promote soil sustainability because the soil lost large amounts of macronutrients and caused 26-33% lower soil net CO 2 exchange rate, compared with leguminous rotations. For future, it could be recommended for ecological farming to rely more on crop rotations with red clover to improve ecosystems functioning.
