“…The obtained results are consistent with those described in the literature on the effects of fertilization on soil microbial activity (Barabasz et al 2002, Kanova et al. 2010, Lazcano et al 2013). In the rhizosphere soil, the number of heterotrophic bacteria was more than three, and that of microscopic fungi more than two orders greater than the size of these groups in the non-rhizosphere soil (Tables 3 and 4).…”

This experimental work was undertaken to assess the effect of various fertilization regimes (CaNPK, NPK, CaPK, CaPN, CaKN and Ca) and different soil properties on growth and yield of Miscanthus plants and to check the impact of this plant on soil microbial characteristics. Field experiment was set up in 2003 on a long-term fertilization experiment, which had been established since 1923. Miscanthus giganteus response to high soil acidity and deficiency of N, P and K was investigated. Some physico-chemical and microbiological properties of soil samples were estimated and microbial characteristics of soil were conducted to investigate the number of the following microorganisms: heterotrophic bacteria, microscopic fungi, and some diazotrophic bacteria. Obtained results showed that, the highest yield of Miscanthus was obtained from the field fertilized with the CaNPK; while the lowest one was found for plants grown without nitrogen (CaPK). The high acidity of soil and small amount of phosphorus did not affect the yields in the NPK and CaKN combinations as compared with CaNPK one. The experiments showed that Miscanthus giganteus responded positively to mineral fertilization, especially with nitrogen. The rhizosphere of Miscanthus plants provides a suitable environment for the growth and development of microorganisms, in contrast to the non-rhizosphere zone.Keywords: energetic plant; microbial characteristics of soil; nutrients in plant and soil Plant Soil Environ. Vol. 60, 2014, No. 3: 117-122 118 MATERIAL AND METHODSThe object of chemical and microbiological analyses was soil taken under Miscanthus giganteus plants grown in different fertilization combinations. The experiment was set up in 2003 in triplicate on the site of a long-term fertilization experiment in which a fixed fertilization scheme had been applied since 1923: CaNPK, NPK, CaPK, CaPN, CaKN, Ca. The experiment was carried out on a podzolic soil formed from heavy loamy sand. Chemical and microbiological tests were carried out over 2010 and 2011 at three different times of the year (spring, summer, and autumn).Chemical tests were carried out on plants and non-rhizosphere soil, whereas microbiological tests included both rhizosphere and non-rhizosphere soils. Rhizosphere soil was taken to be the soil that remained within the root system of Miscanthus plants after shaking them.Soil samples were analysed for pH in 1 mol/L KCl (PN-ISO 10390), total nitrogen (PN-ISO 11261), organic carbon (PN-ISO 10694), available P by Egner-Riehm method (Fotyma et al. 2005), and exchangeable forms of K, Mg and Ca (Ostrowska et al. 1991). Plant samples were analysed for total amounts of macroelements (N, P, K, Mg, Ca, S) (Ostrowska et al. 1991).Microbial characteristics in the soil were assessed on the basis of population sizes of selected physiological groups of microorganisms: heterotrophic bacteria on the Bunt and Rovira medium (1955), and microscopic fungi on the Martin's medium (1950). The most probable number (MPN) of diazotrophic bacteria (Azotobacter sp. a...

“…In this study, long-term compostand peat-applied treatments showed significantly higher respiration rates than the other treatments (Table 4). Lower and no difference in respiration rates were noted between the CK, Chem-N, and GM + 1/3 N treatments, which may be due to the deficiency in available organic C. An energy source is important for biological activities (Lazcano et al 2013). The compost and peat are superior to the green manure as a long-term supply of energy for biological activities even if the peat is resistant to decomposition.…”

Continuous cultivation has been known to decrease soil organic matter content. Application of organic matter to cultivated soil is an important practice from the point of view of maintaining an adequate amount of soil organic matter. Soil organic matter content significantly affects soil microbial activity, which is an important index of soil quality. In this study, a field experiment was conducted to examine the long-term effects of different kinds of organic matter in combination with inorganic nitrogen (N) fertilizer on chemical and biological properties of soils. There were seven treatments, namely (1) The results showed that compared with CK and Chem-N treatments, applications of compost and peat increased soil organic carbon (SOC) content and altered microbial activities and microbial community structure. However, application of green manure for 12 years had no effect on SOC content. Both microbial activities and PLFA profiles were clearly dependent on the characteristics of the applied organic amendments. In summary, a peat application led to the highest increase in SOC content compared to compost and green manure; however, compost-treated soil had a higher microbial population and higher microbial and enzyme activities, while the effects of both green manure and chemical N fertilizer on soil properties were similar.

“…The main objectives in majority of these studies have been its disease suppression properties (Ersahin et al, 2009;Somasekhara et al, 2011;Singh et al, 2012;Carr and Nelson, 2014) and its effect on plant growth and yield (Arancon et al, 2003;Sallaku et al, 2009;Kalantari et al, 2011). There are also some studies focusing on the relationship between vermicompost and soil biological and chemical properties under various soil conditions (Arancon et al, 2006;Gopinath et al, 2011;Tejada and Benitez, 2011;Doan et al, 2013;Lazcano et al, 2013;Doan et al, 2014). However, most of these studies employed soils with neutral or acidic reactions.…”

The aim of this study was to investigate impact of vermicompost on chemical and biological properties of an alkaline soil with high lime content in the presence of plant under the open field conditions in semiarid Mediterranean region of Turkey. The study also included farmyard manure and chemical fertilizers for comparison and was conducted in two consecutive growth seasons in the same plots to observe any cumulative effect. Plots were amended with fertilizers in different rates and celery (Apium graveolens L. var. dulce Mill.) was grown as the test plant. In general, vermicompost appeared to be more effective to increase organic matter, N, P, and Ca compared to farmyard manure. Soil alkaline phosphatase and β-glucosidase activities, especially in the second growth season, were significantly elevated by the vermicompost application. Urease activity, however, appeared not to be influenced by the type of organic fertilizer. A slight but statistically significant difference was detected between organic amendments in terms of number of aerobic mesophilic bacteria with vermicompost giving the lower values. Results showed that, in general, vermicompost significantly alters chemical and biological properties of the alkaline soil with high lime content during celery production under field conditions compared to farmyard manure and that it has a high potential to be used as an alternative to conventional organic fertilizers in agricultural production in the Mediterranean region of Turkey.
