Abstract:

Today, climate change is exacerbating the problems of efficient and environmentally friendly use of acidic soils, which are widespread in Ukraine. At the same time, the role of mobile aluminium compounds in acidity formation is also becoming increasingly important. In this regard, chemical amelioration remains a primary and very important factor in the system of resource-saving and environmentally friendly agricultural measures for the efficient and balanced use of acidic soils. Therefore, the main objective of the research is to establish scientifically sound doses of chemical ameliorant that reduce the content of mobile aluminium compounds and ensure environmental safety and high productivity of agrocenoses on Albic Pantostagnic Luvisol. The research was carried out in a long-term stationary experiment established in 1965 with different doses of mineral fertilisers, manure and lime on an Albic Stagnic Luvisol. It was found that with a prolonged application of mineral fertilisers and the use of this soil without fertilisers, the content of mobile aluminium compounds at the end of the X rotation at pHKCl 4.20 and 4.42 was 68.4 and 58.5 mg kg-1 respectively. Under the organo-mineral and mineral fertilisation systems with liming with 6.0 t ha-1 of CaCO3 calculated by hydrolytic acidity, the content of mobile aluminium compounds decreased to 7.2 and 6.7 mg kg-1 of soil respectively. Under identical fertilisation systems with a lime application by pH-buffering capacity (2.5 t ha-1 CaCO3), the content of mobile aluminium compounds is 10.8–10.0 mg kg-1 soil.

Abstract:

Aluminium toxicity is one of those factors limiting lucerne production on acid soils. Efficient method for selection of Al resistant plants should accelerate breeding of new cultivars. Reaction to Al of the 25 European lucerne cultivars was evaluated using Petri dish with filter paper moistened with AlCl3 concentrations 0, 2, 4, 8, 16 mM. The tested lucerne cultivars did not differ considerably by resistance to Al in regard to the origin. It was clear that aluminium inhibited lucerne seed germination, seedling root and hypocotyl elongation depending on cultivar resistance. Germination rates at AlCl3 concentrations 0, 2, 4 were similar for most cultivars, whereas AlCl3 concentrations 8 and 16 mM highly inhibited germination of susceptible cultivars. Germination test was suitable for elimination of the most susceptible accessions. The seedlings hypocotyl elongation reaction to different AlCl3 concentrations characterized cultivars better than root elongation rates. This method was suitable for selection of the most resistant accessions as only cultivars Magda, Vertus, Luna, Marova out of the 25 ones formed hypocotyls at AlCl3 concentrations 16 mM.

Abstract:

The aim of the studies was evaluation of brown coal ash produced by Power Plant Group Pątnów-Adamów-Konin for agricultural purposes. The subject matter was the estimation of the influence of fly ash applied to light soil on the metal content of soils (aluminium, iron, manganese, copper, nickel and cobalt). The field experiment was conducted on light soil at the area of the Agricultural Experimental Station in Lipnik, Poland. The experiment was set up by means of randomized complete blocks in 4 replications. The study consisted of testing 7 variants (controlburned lime (CaO) dolomite lime CaCO3⋅MgCO3, ash from 1st electrofilterzone, from 2nd electrofilter zone, from 3rd electrofilter zone and mixture of ashes from three electrofilter zones). Lime fertilizers and ashes were applied in a dose corresponding to 1.0 hydrolytic soil acidity expressed in cmol H+ kg-1 of soil. Brown coal fly ash produced by Power Plants ZE PAK S.A., used as soil fertilizer, did not contribute to changes of content of the following metals: iron, zinc, copper, nickel, lead and cobalt in the tested soil. Soil-incorporated brown coal fly ash significantly increased the content of manganese. However, the obtained results did not exceed the allowable standard. In the soil of all fertilizer variants, where brown coal ash was applied, the content of mobile aluminium diminished. When brown coal ash produced by Power Plants ZE PAK S.A. was applied in the experiment, soil reaction changed from acid to neutral and its hydrolytic acidity decreased by ca 50%.

Abstract:

The aim of the study was to check reaction of spring brewer’s barley seedlings to the pH and aluminium concentration of the growing medium. Seedlings of four cultivars of barley (Madonna, Orthega, Philadelphia and Rasbet) were grown at 4 levels of pH (3, 4, 5 and 6) and under 3 doses of Al3+ (0, 150 and 300 µmol dm-3). Significant differences in dry matter of roots and shoots were found for the studied cultivars and plants grown at different pH and concentrations of Al3+. Cv. Madonna had the highest tolerance to aluminium ions at low pH (3 and 4) of the medium and also the highest chlorophyll content in the leaves among those studied. With an increase of aluminium concentration, phosphorus content in dry matter of the leaves decreased from 0.66% in control plants to 0.52% under 300 μmol Al3+ dm-3 and the magnesium content decreased from 0.16% in control to 0.12% under 150 μmol Al3+ dm-3 and 0.10% under 300 μmol Al3+ dm-3.
