In addition to the dry (D) and rainy (R) seasons, a combination of the two i.e., rainy-dry (RD) and dry-rainy (DR), can also be observed in one year. The effects of the dry (D) and rainy (R) on soil are known, hence we hypothesized that the effects of the rainy-dry (RD) and dry-rainy (DR) periods on soil may differ from the former assessments. The aim of the study is to investigate the effect of six tillage treatments (ploughing—P, disk tillage—DT, loosening—L, tine tillage (a deeper—T and a shallower—ST) and no-till—NT) on earthworm abundance and crumb ratio during a long-term research (16 years) on Chernozems. The results related to the four year-groups (D, R, RD, and DR) with different residue cover. Seven degrees of cover ratio (between 12.5% and 62.5%) were selected on stubbles. Higher cover ratio (≥52.5%) improved water conservation, increased earthworm abundance (31 and 41 ind m–2) and crumb (78 and 82%) ratio (p < 0.01). R year came first in the rank of water content and earthworm abundance and DR proved to be more favorable for crumb formation. Considering the rank of soil tillage treatments, ST takes first place in evaluation of soil water content (SWC) and crumb ratio, and NT for earthworm abundance.

Vineyard floor management has been widely discussed for many decades, but it is still unclear how its intensity levels change the fungal community structure of grape rhizosphere. Our objective was to examine the density and rate of the habitats of fungi in three vineyards that differ only in the methods of tillage procedure applied, namely intensive, extensive and none (abandoned). The hypothesis was that in the cases of lower intensity or no soil tillage, there would be a higher level of fungal diversity with a lower ratio of pathogen strains in grape rhizosphere. In the course of this research, it has been determined that the level of fungal colonization of roots is the highest in the extensively managed vineyard, unrelated to season (spring and summer). Four of the five fungal genera detectable in all of the three sampled vineyards are registered as opportunist grape pathogens, however the fifth one, Trichoderma, is commonly used in biological plant protection. The diversity of fungal communities in grape rhizosphere, in accordance with the expectations, was the lowest in the intensively cultivated and highest in the abandoned vineyard, and it was not affected by seasons. The proportion of opportunist plant pathogen groups was higher in the intensive variant than in the other two (less-intensive variants); therefore, it is possible to conclude that soil under similar conditions but disturbed by intensive tillage methods tends to exhibit lower suppressivity.

Inter-rows in vineyards are commonly tilled in order to control weeds and/or to conserve water. While impacts of tillage on earthworms are well studied in arable systems, very little is known from vineyards. In an experimental vineyard, the impact of four reduced tillage methods on earthworms was examined: rotary hoeing, rotary harrowing, grubbing and no tillage. According to an erosion prevention programme, tillage was applied every other inter-row only while alternating rows retained vegetated. Earthworms were extracted from the treated inter-rows 10, 36, 162 and 188 days after tillage. Across dates, tillage methods had no effect on overall earthworm densities or biomass. Considering each sampling date separately, earthworm densities were affected only at day 36 after tillage leading to lower densities under rotary hoeing (150.7 ± 42.5 worms/m<sup>2</sup>) and no tillage (117.3 ± 24.8 worms/m<sup>2</sup>) than under rotary harrowing (340.0 ± 87.4 worms/m<sup>2</sup>) and grubbing (242.7 ± 43.9 worms/m<sup>2</sup>). Time since tillage significantly increased earthworm densities or biomass, and affected soil moisture and temperature. Across sampling dates, earthworm densities correlated positively with soil moisture and negatively with soil temperature; individual earthworm mass increased with increasing time since tillage. It was concluded that reduced tillage in vineyards has little impact on earthworms when applied in spring under dry soil conditions.

Abstract During the years 2012‒2016 at the site threatened by erosion, the effect of different intensity and depth of soil tillage on the progression of erosion were evaluated on the plots with silage maize. Three different tillage methods were compared and evaluated - conventional tillage, including ploughing (CT), no-tillage using mulch and direct drilling (NT), and minimum tillage treatment with a lower depth of soil cultivation and organic matter incorporation (MT). Water and soil runoff on all of the experimental plots were measured during erosion events. Besides an analysis of naturally occurring rainfall causing erosions, we also conducted the test of soil infiltration abilities with a rain simulator after silage maize harvest. The effect of the tillage on aboveground biomass yield and the input costs was also analyzed. The results showed that NT and MT can significantly reduce water and soil runoff comparing CT. The highest yields were recorded in MT, while the lowest were in CT. Total input costs were higher in the case of NT and MT, but the share of mechanized work was lower for these technologies. Our results showed that NT and MT technologies, as a part of silage maize with a higher plant density stand establishment, should be a useable erosion control measure in areas vulnerable to erosion.

In 2014–2016 in Zakame of the Republic of Tatarstan, a study was conducted to increase the productivity of corn (Mashuk 250 hybrid) for silage using various fertilizer systems (without fertilizers – control, NPK at 40 t/ha of green mass, PK - background, background + N40, background + N60 , background + N80, background + N100, background + N120) and tillage methods (plowing - control, tillage cultivation). The availability of phosphorus in the soil of the experimental plot was sufficient for the formation of the planned yield, therefore, phosphorus fertilizers were not added. The nitrogen content in the green mass of corn for plowing was 3.03 ... 3.85%, phosphorus - 0.45 ... 0.71%, potassium - 1.71 ... 1.98%, for non-dump processing, respectively - 3.01 ... 3, 83; 0.43 ... 0.69 and 1.69 ... 1.97%. Against an unfertilized background, the nitrogen content in the green mass of corn for plowing was equal to 3.03%, with the introduction of NK under the yield of 40 t/ha - 3.41%, K - 3.14%. In the variant with the use of anhydrous ammonia at a dose of 40 kg of active substance/ha against a background of potash fertilizers, the amount of nitrogen in the green mass was 3.34%, 60 kg - 3.41%, 80 kg - 3.43%, 100 kg - 3.76% and 120 kg - 3.85% (0.82% higher than unfertilized background). The maximum NPK removal in the experiment was observed by plowing in the background + N120 variant (1183; 218; 608 kg/ha, respectively), background + N100 (1114; 207; 584 kg/ha) and when fertilizing with a yield of 40 t/ha of green mass (1051; 206; 598 kg/ha). With subsurface processing, the take-off decreased, but the distribution of the first variants of this indi

Abstract The objective of this study was the model comparison and economic evaluation of different methods of soil tillage and crop stand establishments used. Based on yield results (winter wheat, spring barley, and white mustard cultivated in three-crop rotation) from field experiments with conventional, conservation with minimum tillage, and no-tillage methods conducted at the site Prague-Ruzyně, model economic balances were evaluated. Prices of the main products were determined based on the yield results from the period 2010-2013 and the current market prices. In the individual tillage systems, the total costs of production of evaluated crops were counted up and profitability was calculated as a ratio of profit to total costs. The highest total costs of crop cultivation were identified in cereals under conventional soil tillage, on the contrary, the lowest in cereals cultivated under conservation tillage technology. As for the growing technologies, the highest profitability was found in winter wheat, as for the tillage methods, it was in the conservation variant with minimum tillage. The economic evaluation for individual crops was based on standards of growing technologies and particular work operations.
