Research objectives:
Research activities of this research group are scoped on the study of the sustainable plant nutrition management, and phytoremediation of toxic elements.
Description and results of research:
Our activities are the followings:
- In open-field trials the impacts of various mineral fertilizers and wastes (e.g. municipal sewage sludge sediment, municipal sewage sludge compost, municipal biocompost) and mineral amendments (rhyolite tuff, willow ash are) are studied on energy crops (willow, black locust, giant reed). Yield, mineral nutrient plant uptake and soil leaching, accumulation of toxic elements in plants, microanatomical and physiological (enzyme activity, photosynthesis) responses of plants, and microbial activity, respiration of soils are followed.
- At our University Training Farm (Nyírtelek, Ferenctanya) open-field large plot experiments are conducted to study the effects of mineral fertilizers (e.g. ammonium nitrate, ammonium nitrate with calcium-magnesium carbonate, sulphuric urea), organic manures (e.g. poultry manure), biowastes (municipal sewage sludge compost), mineral amendments (rhyolite tuff, dudarit, alginit) and innovative foliar fertilizers in maize, wheat hybride and common wheat cultures.
- At organic farming areas of University Training Farm macro- and micro-nutrient turnover is studied in various second sowing green manure crops (e.g. daikon radish, sunn hemp, multi-component green manure crop mixtures). Yield and mineral nutrition of after cultured sunflower, physical and biological soil conditions of soils are studied.
- In collaboration with University of Debrecen Institute of Ecology at Debrecen-Lovászzug area the toxic element phytoremediation potential of various herbaceous (e.g. Arundo, Sorghum sp.) and woody plants (elm and white willow sp.) is studied. Plants are grown in former sewage settling ponds where sewage sediment is covered now with uncontaminated soil. Processes in contaminated soils and in plants are modelled running growth chamber pot experiments.
