“…Results of investigations by López-Bellido et al (1998) and De Vita et al (2007) indicate that in the areas with low precipitation, higher yields are noted for cereals cultivated in the no-till than in the conventional tillage system. This was also confirmed by findings of Guy and Cox (2002) and these by Hemmat and Eskandari (2004). The agrotechnical factors influence also the quality of grain (Morris et al 2010), though a research by Gomez-Becerra et al (2010) demonstrates that these characteristics are strongly dependent on the agroclimatic conditions.…”

The objective of this study was to analyze the effect of tillage systems and nitrogen fertilization on the grain yield and quality of spring wheat and on selected chemical and biological properties of soil. The first order factor was the tillage system: (1) conventional (CT) -shallow ploughing and harrowing after harvest of the previous crop, and pre-winter ploughing; (2) reduced (RT) -only a cultivator after harvest of the previous crop, and (3) no-tillage (NT) -only Roundup 360 SL herbicide (a.s. glyphosate) after harvest of the previous crop. The second order factor was nitrogen dose: (1) 90 kg N/ha and (2) 150 kg N/ha. Higher yields were demonstrated for spring wheat sown in CT and RT systems, compared to the NT system. In addition, grain yield was increased by a nitrogen dose of 150 kg/ha, compared to 90 kg/ha. Contents of protein and wet gluten in the grain were also increased by the higher nitrogen dose. The RT and NT systems were observed to increase the content of organic C, total N and available phosphorus in the soil, compared to the CT system. They also increased the number and mass of earthworms in the soil, compared to the CT system.

“…Erosion can be reduced with greater residue cover, soil roughness, and improved water infiltrations with residue cover usually the most effective. Seedbed preparation for winter wheat reduces crop residue groundcover and surface roughness (Guy and Cox, 2002;Elliot et al, 1999). Besides improved erosion control, crop residue provides organic matter for the soil and improves the www.elsevier.com/locate/still Soil & Tillage Research 91 (2006) [89][90][91][92][93][94] physical, chemical and biological properties of dryland soils (Black and Unger, 1987).…”

A minimum plant residue groundcover of 30-50% is recommended for adequate erosion protection (Guy and Cox, 2002;Schertz and Bushnell, 1993).…”

“…In fact, according to Shelton et al (1995), the values of the residue cover for maize can range from 18.6 to 46.5% in dependence on different conservation management applied in complete tillage and planting systems. Also Guy and Cox (2002) refer that tillage intensity had more influence on carryover residue levels than previous crop type.…”

“…Area-wide tillage systems, in comparison with the previously described management, generally show a lower level of the ground coverage by plant residues (Shelton et al 1995). Referring to Guy and Cox (2002), together with plants residues decomposition over the time and particular tillage systems which incorporate some part of plant remains into soil profile, it is difficult to ensure a certain level of biomass to be left on the field surface as an erosion protective layer -concretely over the 30% groundcover by plant residues recommended for erosion control. The soil coverage can be increased by sowing overwintering or winter non-surviving intercrops into maize and other wide-sowing crops (Bohren 2000;Feil & Liedgens 2001), but always just to a certain extent.…”

Brant V., Kroulík M., Pivec J., Zábranský P., Hakl J., Holec J., Kvíz Z., Procházka L. (2017): Splash erosion in maize crops under conservation management in combination with shallow strip-tillage before sowing. Soil & Water Res., 12: 106−116.Soil under maize cropping is among the most endangered by erosion. The effect of conservation tillage management on values of splash erosion when using shallow strip tillage before sowing maize was evaluated in the Central Bohemian region (Czech Republic) during the period 2010-2012. The following types of tillage management using conventional technology and shallow tillage were evaluated: ploughed plots with mulch formed by weed biomass (PL W ), ploughed plots with mulch from perennial ryegrass plants (PL PR ), ploughed plots without mulch (PL) and shallow tillage (ST) where the mulch was formed by cereals straw. Furthermore, values of the splash erosion, plants and plant residues coverage ratio of soil by image analysis and the stability of soil aggregates were monitored during the whole experiment. The average value of splash erosion (MSR) was higher by 18.7% in the variant of PL W , lower by 35.9% in PL PR , and lower by 39.5% in ST, than in the control treatment PL (MSR value for PL = 100%) for the whole evaluated period (2010)(2011)(2012). The average values of the soil surface plant coverage ratio in the plots with mulch ranged from 1.5 to 43.0% at the beginning of the vegetation period, and from 4.9 to 85.5% in the second half of the vegetation period. A positive correlation was observed between the average values of the stability of soil aggregates and the plant coverage ratio of the soil surface in 2010 and 2011.
