“…Soil under both cereals grown in RT demonstrated an increasing trend of microbial biomass as compared to CT (by 11.2% under maize, and by 38.2% under wheat, respectively). The observed positive effects of RT on DHa activity in this study were similar to the results obtained by Mikanová et al (2009), Sikora et al (2011 and Wolińska et al (2015). Negative impacts of CT on MBC and MBN contents were also confirmed by numerous studies, e.g.…”

The aim of the study was to compare the activity and functional biodiversity in soil under two different cereals: common maize and winter wheat, both grown in the same pattern of cultivation techniques: conventional (to 25 cm depth) and reduced (to 10 cm depth). Soil samples for comparative analysis were collected at the same time (July 2016) at a long-term field experiment, which was carried out in 2013–2016. Soil biological activity was determined by measurement of dehydrogenases activity (DHa) with TTC (2,3,5-triphenyltetrazolium chloride) application, microbial biomass carbon (MBC) and nitrogen (MBN) content by fumigation-extraction method, and functional diversity of soil microorganisms using the Biolog EcoPlate System. The results demonstrated that the cultivation technique had a greater impact on the soil biological activity, compared to the type of cereal. Higher biological activity was found in the soil under reduced tillage in both cereals. Calculated correlations showed that DHa, MBC, MBN and acid phosphatases were positively correlated with each other. The negative correlation obtained between yield and biological parameters of activity in soil was not expected.

“…The increase of soil microbial activities and biomass after reduction of tillage has been reported by several authors, particularly in the top soil layer (Melero et al 2009, Mikanová et al 2009). Changes in the dynamics of the microbial community occur from the interactions between tillage, soil moisture, temperature, aeration, and substrate availability (Sainju et al 2007).…”

The field experiment with different soil tillage treatments has been carried out in Prague-Ruzyně locality (Czech Republic) since 1995. Data of two growing cycles in the years 2007-2010 and 2011-2014 were evaluated. Tillage technique was decisive for changes in soil characteristics and crop yields. Bulk density, organic carbon (C org ) and microbial biomass C (C mic ) were more equilibrated throughout all tested soil layers (0-0.1; 0.1-0.2 and 0.2-0.3 m) in conventional tillage (CT). In reduced tillage (RT) and no-tillage (NT) treatments significant accumulation of C org and increase of C mic in the surface layer were found, compared to CT. No significant differences in C org and C mic between two growing cycles were determined; however, mostly higher values were obtained in the top layer of NT during the second growing period. Higher bulk density under conservation tillage techniques did not negatively affect soil characteristics and should be taken in consideration for data evaluation as it can alter interpretation of their changes in the soil profile. Crop yields were comparable in CT and RT. Yield decrease in NT was mostly observed for winter wheat and pea. Beneficial effects of RT and NT conserving soil moisture on crop yield were not observed in dry years.

“…Apparently, the input of organic matter was higher and the mineralization processes were less intensive in this variant, compared to the CT treatment. The beneficial effect of crop residues in the no till system, in which crop residues remain on the surface, and soil organic matter accumulates in the upper layer, was also cited by Mikanová et al (2009). Lipavský et al (2008), who showed that the cereal straw and mineral nitrogen fertilizers may substitute for farmyard manure in its effect on crop yields and organic C content in the topsoil.…”

Soil quality and fertility are associated with its productivity, and this in turn is connected to the soil biological activity. To study these effects, well designed long-term field experiments that provide comprehensive data sets are the most applicable. Four treatments (tillage methods) were set up: (1) conventional tillage (CT); (2) no tillage (NT); (3) minimum tillage + straw (MTS), and (4) no tillage + mulch (NTM). Our objective was to assess the relationships between soil microbial characteristics and winter wheat yields under these different techniques of conservation tillage within a field experiment, originally established in 1995. The differences in average grain yields over time period [2002][2003][2004][2005][2006][2007][2008][2009] between the variants were not statistically significant. Organic carbon in the topsoil was higher in plots with conservation tillage (NT, MTS, and NTM), than in the conventional tillage plots. There was a statistically significant correlation (P ≤ 0.01) between the grain yields and organic C content in topsoil.
