“…A significant increase in soil aggregate stability was determined in the 10-25 cm layer as well: in the treatment of shallow rotovating before sowing 21. aggregate stability is the lowest if the soil is annually deeply or shallowly ploughed, and incorporation of straw residues has a tendency to increase aggregate stability. Similar trends were found in the research conducted by Bogužas et al (2010) and Velykis and Satkus (2018). Notillage has a positive effect on soil structure, significantly reducing the amount of small aggregates and increasing the amount of stable aggregates not only in the upper 0-10 cm layer but also in the 10-25 cm layer.…”

“…No-tillage technology has many advantages for economic and environmental protection, and it is currently used on 117 million ha worldwide and 1.15 million ha in Europe (López et al, 2012;Romaneckas et al, 2015). Feiza et al (2010) and Velykis and Satkus (2018) have reported that tillage and crop rotation are fundamental factors that influence soil quality and sustainability of cropping systems, soil physical properties depend on tillage intensity and soil depth. Bogužas et al (2010) have documented that the aggregate structure of soil did not change significantly with different tillage technologies.…”

Since 1999, a long-term field experiment has been done at the Experimental Station of the Lithuanian University of Agriculture (currently-Vytautas Magnus University). The current research was conducted in 2013-2015. The aim of the study was to evaluate the effects of long-term tillage systems and straw management on soil penetration resistance, shear strength and soil aggregate stability. The soil of the experimental site was Epieutric Endocalcaric Endogleyic Planosol. A short crop rotation was introduced: winter wheat → spring barley → spring oilseed rape. According to two factor field experiment, the straw was removed from one part of the experimental field, and on the other part of the field the straw was chopped and spread at harvesting (factor A). Six tillage systems: conventional (deep) and shallow ploughing, shallow loosening, shallow rotovating, catch cropping and rotovating, and no-tillage, were used as a subplot (factor B). During a 16-year (1999-2015) period, long-term application of reduced tillage resulted in a significant increase in soil penetration resistance and shear strength. The results of current study show that the lesser the tillage depth, the higher the soil penetration resistance and shear strength. The effect of straw residue spreading was lower comparing with treatment without straw. Soil aggregate stability was highly dependent on tillage. Shallow rotovating before sowing increased soil aggregate stability by up to 1.8 times, incorporation of plant residues of white mustard into the soil by a rotovator before sowing increased it by up to 2.0 times and no-tillage by up to 1.9 times, compared with conventional ploughing.

“…The volume (m 3 ) of soil aggregate fractions i.e., fine, medium, and coarse was determined (Figure 2). The ratio of the aggregate fractions was an indicator of soil quality and calculated according to the methodology provided in the literature (Slawiñski et al 2011;Usowicz and Lipiec, 2017;Velykis and Satkus, 2018). The disc harrows and spring harrows loosened the soil layer to a certain depth, which was named as the working depth of the implement.…”

Over the years, tillage became less intense due to environmental safety requirements in order to minimize fuel and labour time. Mostly, this is achieved by reducing the depth of tillage. However, highly cut winter rape stubble is the main challenge for reduced tillage to prepare clear soil, especially as the summer droughts intensify. The aim of this study was to determine the optimal tillage performances of the spring tine cultivator and compact disc harrow and establish the fuel consumption required to achieve the preferred level of soil structure formation and residue incorporation on loam and clay loam soil after a rape harvest. The fuel consumption depends on the desired level of soil tillage intensity, implement type, tillage depth (5 and 8 cm), and forward speed (1.4, 1.9, 2.5, 3.1, and 3.6 m∙s-1). The tractor “CASE IH 135” was instrumented with an additional data acquisition system and was used to perform the indicators of stubble tillage. The research examines the dependence of the tractor-implement regime mode on the soil aggregate ratio, which varied from 0.10 to 0.21, and the residue interblending ratio, which varied from 0.60 to 0.96. The relationship was established by obtaining the tillage quality level and reduced fuel consumption, which varied from 3.4 to 5.9 L·ha-1, depending on soil type. Minimization of fuel consumption and sufficient quality of oilseed rape stubble cultivation was achieved by reducing the depth but not the speed of tillage.

“…It is well known that extensive tillage has certain benefits over the conventional, such as reduced costs (especially through fuel use), soil erosion, nitrate leaching, increased soil organic matter and activity of soil organisms, improved soil structure and preserved soil moisture [ 1 , 2 , 3 , 4 ]. Nevertheless, extensive tillage systems often face problems, including soil compaction [ 5 , 6 ], weed [ 7 , 8 , 9 ] and disease management [ 10 ]. Consequently, noninversion tillage is considered one of the major factors contributing to fusarium head blight (FHB) development, since it causes the increased inoculum resulting due to the presence of a high quantity of host plant residues on the soil surface [ 11 , 12 , 13 ].…”

The establishment of the harmful pathogen Fusarium graminearum in different agroecosystems may strongly depend on the ability of the soils to suppress its development and survival. This study aimed to evaluate the influence of different soil tillage systems (i.e., conventional tillage, reduced tillage and no-tillage) on soil fungistasis against F. graminearum. Soil samples were collected three times during the plant growing season in 2016 and 2017 from a long-term, 20-year soil tillage experiment. The F. graminearum in the soil samples was quantified by real-time qPCR. The soil fungistasis was evaluated by the reduction in the radial growth of F. graminearum in an in vitro assay. The antagonistic activity of the soil bacteria was tested using the dual culture method. The F. graminearum DNA contents in the soils were negatively correlated with soil fungistasis (r = –0.649 *). F. graminearum growth on the unfumigated soil was reduced by 70–87% compared to the chloroform fumigated soil. After the plant vegetation renewal, the soil fungistasis intensity was higher in the conventionally tilled fields than in the no-tillage. However, no significant differences were obtained among the tillage treatments at the mid-plant growth stage and after harvesting. 23 out of 104 bacteria isolated from the soil had a moderate effect, and only 1 had a strong inhibitory effect on the growth of F. graminearum. This bacterium was assigned 100% similarity to the Bacillus amyloliquefaciens Hy7 strain (gene bank no: JN382250) according to the sequence of the 16S ribosome subunit coding gene. The results of our study suggest that the presence of F. graminearum in soil is suppressed by soil fungistasis; however, the role of tillage is influenced by other factors, such as soil biological activity, type and quantity of plant residues and environmental conditions.
