Selection of plant physiological parameters to detect stress effects in pot experiments using principal component analysis

Anna Füzy, Ramóna Kovács, Imre Cseresnyés, István Parádi, more

Acta Physiologiae Plantarum > 2019 > 41 > 5 > 1-10

Appropriate selection and well-timed measurement of plant developmental, morphological and physiological parameters are essential to maximize efficacy and minimize time consumption of experiments. To select for the most sensitive indicators of drought or salt stress, three independent pot experiments with diverse setups were analysed with 20–20 measured parameters. Parameters of plant growth, phenology...

Potential nitrogen fixation changes under different land uses as influenced by seasons and biochar amendments

Agota Horel, Imre Potyó, Tibor Szili-Kovács, Sándor Molnár

Arabian Journal of Geosciences > 2018 > 11 > 18 > 1-10

Soil nutrient dynamics, potential biological nitrogen fixation (BNF) changes, and their relations were studied using four land use types. Further, we investigated BNF changes in the presence of biochar in soils. Soil samples were collected from arable, vineyard, grassland, and forest soils during four seasons, and analyzed for abiotic contents of total nitrogen, NH₄⁺-N, NO₃⁻-N, ammonium lactate (AL)-soluble...

The application of a filter‐based assembly model to develop best practices for Pannonian sand grassland restoration

Melinda Halassy, Anand Narain Singh, Rebeka Szabó, Tibor Szili‐Kovács, more

Journal of Applied Ecology > 53 > 3 > 765 - 773

The application of a filter‐based assembly model is a promising concept to support ecological restoration. The filters illustrate dispersal, abiotic and biotic constraints that narrow down the species pool and determine the realized species composition. The aim of restoration interventions is the manipulation of filters to achieve a restoration target. We tested the applicability of a filter‐based...

Long‐term outcome of nitrogen immobilization to restore endemic sand grassland in Hungary

Katalin Török, Katalin Szitár, Melinda Halassy, Rebeka Szabó, more

Journal of Applied Ecology > 51 > 3 > 756 - 765

Soil nitrogen immobilization by carbon amendment is a management technique used for conservation purposes to increase the competitive ability of late‐seral plant species over early‐seral species based on their different tolerance of low soil nitrogen content.We immobilized nitrogen over six growing seasons on three ex‐arable fields with poor sandy soils in the Hungarian lowland in order to restore...

Contribution of Agricultural Field Production to Emission of Greenhouse Gases (Ghg)

Ágnes Bálint, Sándor Hoffmann, Attila Anton, Tibor Szili-Kovács, more

Ecological Chemistry and Engineering S > 2013 > 20 > 2 > 233-245

According to global inventories the agricultural field production contributes in a significant measure to increase of concentration of greenhouse gases (CO₂, N₂O, CH₄) in the atmosphere, however their estimated data of emissions of soil origin differ significantly. Particularly estimates on nitrogen-oxides emissions show a great temporal and spatial variability while their formations in microbial...

Promoting microbial immobilization of soil nitrogen during restoration of abandoned agricultural fields by organic additions

Tibor Szili-Kovács, Katalin Török, Emma L. Tilston, David W. Hopkins

Biology and Fertility of Soils > 2007 > 43 > 6 > 823-828

Application of organic materials to soils to enhance N immobilization into microbial biomass, thereby reducing inorganic N concentrations, was studied as a management option to accelerate the reestablishment of the native vegetation on abandoned arable fields on sandy soils the Kiskunság National Park, Hungary. Sucrose and sawdust were used at three different topographic sites over 4 years. N availability...
