The efficiency of the application of microbial preparations enhancing soil properties as well as the diversified fertilization of spring wheat nitrogen was evaluated in the field experiment. Factors of the experiment referred to the levels of nitrogen fertilization: 0, 40, 80, 120 and 160 kg/ha as well as the application of microbial preparations, namely, Proplantan (disaccharide, and polysaccharide, lactic acid, carotene, riboflavin, thiamine, amylase, sea salt, minerals), Effective microorganisms (milk bacteria, photosynthetic bacteria, yeast, actinomycetes, moulds) and UGmax microorganisms (lactic acid bacteria, photosynthetic bacteria,...

Root net primary productivity (RNPP) was assessed in the wet submontane meadow in the highland region of the Czech Republic. RNPP was studied from 1992 to 1995 with help of the in-growth core technique. The effect of different intensities of fertilization on root growth was covered. In comparison with unfertilized stands, the application of fertilizers (90 kg N/ha) resulted, mostly significantly, in greater root productivity (297 g/m2/year and 2.08 g/m2/day, on average). This represented an increase by 72% and 71%, respectively. Variability in the fraction of RNPP to total net primary productivity was examined. Results indicate...

A field study was conducted to ascertain the effect of three zinc (Zn) levels: 0, 20 kg ZnSO4/ha and 20 kg ZnSO4/ha + foliar spray of 0.5% ZnSO4, on wheat grain Zn content and factors contributing to or hindering in its bioavailability. Increasing Zn levels were established as serviceable in improving the nutritional status of genotypes. Soil application + foliar spray proved to be paramount for all the traits leading to an 80% increase in grain Zn content, 61.3% in methionine content and a decrease of 23.2% in phytic acid as an average of all genotypes and both years. The genotype UP 2382 was found more suited to Zn...

The effect of mercury (Hg) on the electrophysiological and permeability properties of grapevine adventitious root cells was examined. In short-term experiments, the apical segments of adventitious roots were treated with different concentrations of mercury (0.01 µmol/L to 2 µmol/L HgCl2), and trans-membrane electrical potential differences (EM) were monitored in root cortical cells, localized in distinct root zones. Based on Hg-induced decrease of EM, we can confirm that the depolarization of the membrane is an instant Hg-response and the extent of EM decrease is not only time- and concentration...

The research results have shown that the enzyme pH index (0.49-0.83) confirmed the neutral or alkaline nature of the soils. Neither the changes in the content of available phosphorus nor in the activity of dehydrogenases, catalase, alkaline and acid phosphatase in soil were due to the factors triggering soil salinity; they were a result of the naturally high content of carbon of organic compounds, which was statistically verified with the analysis of correlation between the parameters. There were recorded highly significant values of the coefficients of correlation between the content of available phosphorus in soil and the activity of alkaline (r...

The impact of transgenic Bacillus thuringiensis (Bt) cotton residues on soil microorganism communities was investigated. Leaves of three different varieties of transgenic Bt cotton and their near-isogenic lines were placed in soil and the numbers of indigenous soil microorganisms were measured with cultivation-dependent approaches under laboratory conditions. The soil samples were collected after 7, 14, 21, 28, 56 and 84 days of incubation. Numbers of bacteria, actinomycetes and fungi in the soil were measured by counting colony forming units after incubation on appropriate medium. Overall, although there were differences...
Diagnostics of boron deficiency for plants in reference to boron concentration in the soil solutionOriginal Paper

Plant Soil Environ., 2013, 59(8):372-377 | DOI: 10.17221/306/2013-PSE
The determination of a range of boron concentration in the soil solution, evaluation of the effect of physico-chemical soil properties on boron concentration in the soil solution as well verification whether boron quantity in the soil solution is sufficient for nutritional needs of selected plants cultivated in Poland were comprised. Average boron concentration in the soil solution of Poland's cultivated soils ranges from 0.59 to 5.07 µmol/L and is differentiated by physico-chemical properties of soil. Taking into account decreasing effects of soil properties on the increase of boron concentration in the soil solution, the soil properties can...

The paper deals with a general solution of semantic description related to various electronic data formats in the domains of agriculture, aquaculture, forestry, food industry, environment, horticulture and rural areas. The solution presented was developed on the basis of metadata formats analysis and then complemented with its own software superstructure. It is based on the VOA3R metadata application profile (AP) that was developed within the framework of the Virtual Open Access Agriculture and Aquaculture Repository project for the sake of describing research papers and scientific publications. However, thanks to its complexity and comprehensiveness,...
