“…This was represented by 72 bands in total, whereas the CT soil was represented by only 67 bands in total (Table 3). These findings are consistent with those reported by Mathew et al (2012) and Peixoto et al (2006). Moreover, Silva et al (2013) reported that in a long-term field experiment, the DNA profiles representative of each tillage treatment showed differences in soil bacterial diversity, with greater diversity under NT, compared to the other systems studied, inter alia CT.…”

The effects of different tillage systems on the properties and microbial diversity of an agricultural soil was investigated. In doing so, soil physical, chemical and biological properties were analysed in 2013-2015, on a long-term field experiment on a loamy sand at the IUNG-PIB Experimental Station in Grabów, Poland. Winter wheat was grown under two tillage treatments: conventional tillage using a mouldboard plough and traditional soil tillage equipment, and reduced tillage based on soil crushing-loosening equipment and a rigid-tine cultivator. Chopped wheat straw was used as a mulch on both treatments. Reduced tillage resulted in increased water content throughout the whole soil profile, in comparison with conventional tillage. Under reduced tillage, the content of readily dispersible clay was also reduced, and, therefore, soil stability was increased in the toplayers, compared with conventional tillage. In addition, the beneficial effects of reduced tillage were reflected in higher soil microbial activity as measured with dehydrogenases and hydrolysis of fluorescein diacetate, compared with conventional tillage. Moreover, the polimerase chain reaction – denaturing gradient gel electrophoresis analysis showed that soil under reduced till-age had greater diversity of microbial communities, compared with conventionally-tilled soil. Finally, reduced tillage increased organic matter content, stability in water and microbial diversity in the top layer of the soil.

“…Simplified cultivation systems involving shallower and less intensive interference in the soil physical structure frequently without translocation of soil layers in the soil vertical profile (reduction tillage, conservation tillage) or even complete abandonment of cultivation treatments (no-tillage, direct sowing) offer an alternative to the traditional ploughing cultivation across the entire depth of the soil humus horizon. The above-mentioned simplifications, irrespective of their economical consequences, are also associated with various repercussions of a physico-chemical, biological, and ecological nature [1][2][3][4].…”

The scale and extent of the impact of farming on the natural environment are so wide-ranging that in many places on our planet, and especially in Europe, an ever growing pressure is being exerted on limiting or eliminating negative effects of this impact. Actions in this sphere adopted a concept of so-called sustainable farming, which combines production objectives with the requirements of environmental protection thanks to the application of integrated plant proPol. J. Environ. Stud. Vol. 24, No. 1 (2015), [285][286][287][288][289][290][291][292][293][294] Original Research Microbiological AbstractTraditional ploughing cultivation can contribute to soil erosion as well as to other symptoms of soil degradation, leading to a decline in its biological and production potentials. An alternative to conventional tillage is offered by simplified cultivation systems consisting of shallower and less intensive interference into the soil physical structure or even complete abandonment of cultivation treatment. The aim of the performed investigations was to ascertain the impact of a long-term application of simplifications in soil tillage on select soil chemical and microbiological properties under sugar beet cultivation employing two watering combinations: natural distribution of precipitation and sprinkling. Conventional ploughing tillage was treated as reference. The research hypothesis assumed that the application of simplifications in the pre-sowing soil cultivation of sugar beets contributes to the increase in soil organic carbon content and soil fertility. Its microbiological activity and sprinkling also can modify this effect.Experiments were carried out for a period of four years in conditions of long-term application of three tillage systems (conventional tillage, simplified cultivation, and direct sowing). Select soil chemical (pH, C org. , total N) and microbiological (total bacterial counts, numbers of oligotrophs, copiotrophs, actinomycetes and fungi, plus activity of dehydrogenases and acid phosphatase) parameters were analyzed.The microbiological indices analyzed in this study nearly always spoke in favour of simplifications in soil tillage or complete abandonment of cultivation treatments. In successive years of experiments, almost all the analyzed parameters assumed the lowest values in conditions of ploughing cultivation and the highest ones in direct sowing. Sprinkling and fertilization modified this rule, whereas the level and directions of this impact varied and depended on weather conditions.

Response of Organic Matter Decomposition to No-Tillage Adoption Evaluated by the Tea Bag Technique

Organic matter (OM) decomposition is a fundamental ecosystem service in conservation agriculture, but the response of this process to the conversion from conventional tillage (CT) to no-tillage (NT) systems is not fully understood, especially during the transition period. Here, using a litterbag experiment (tea bag technique), we studied OM decomposition in a chronosequence of NT fields of different ages since conversion from CT (1 to 7 years) around Beauvais (northern France). We found that, in contrast with physico-chemical soil properties, the decomposition of both high quality (green tea) and low quality (rooibos tea) organic matter was significantly correlated with the NT age. Irrespective of the OM quality, the OM mass losses linearly increased with the time span since conversion from CT to NT. Taken together, our results suggest that adopting NT practices provides more favorable habitats for microorganisms involved in OM decomposition.
