The paper verified the hypothesis of the existence of the correlation between the content of zinc in soils and plants in the municipality of Trzebinia that is in the area which is highly degraded as a result of long term activity of mining and processing of local raw materials. In order to achieve the above, the total metal content in plant and soil material as well as the selected physicochemical properties of soil such as pH, electrolytic conductivity, organic matter content and granulometric composition were determined. 664 soil material samples and 332 plant material samples were collected in years 2010-2012 from 83 research plots located in fallow lands of the town of Trzebinia and in 10 village councils of the municipality. The results obtained of zinc content do not confirm the correlation between soil and plant. The disclosed concentration of the element is in line with indications of permitted levels of metal content in plants proposed by IUNG, which allows the use of plant material as animal feed. The mean content of zinc in the soils of the municipality is higher than the permitted level of national regulations. The claim that the soil of the municipality is contaminated with ...
The aim of the article was to determine the content of heavy metals (lead) in soils and plants in areas heavily degraded by mining and processing industries. The study was con-ducted in the area of the municipality of Trzebinia, in the western part of the Małopolska province. Altogether 83 research areas were designated (one area of 25 m2) from which the plant material and soil samples were taken from the levels of 0-20 cm and 20-40 cm. The analysis of soil material was based on the determination of granulometric composition of the soil with the use of the Casagrande method modified by Prószyński [according to the industry standard (BN-78/9180-11), soil reaction in 1M KCl and in water with the use of the potenti-ometric method, electrolytic conductivity of the soil with the use of the conductometric meth-od, content of organic matter in soil by its annealing using the modified Tiurin method, the total Pb content in the soil using the FAA method. The analysis of plant material was based on the determination of the total content of Pb in plants using the atomic absorption spec-trometry. It was found that the mean lead content in the soil for the municipality exceeded the ...
Many agro-technical factors are of great importance concerning the amount of crop in corn production. One of these factors is nutrient supply. Plants are supplied with macro-, meso- and microelements. Nowadays cultivated plants cannot always obtain enough microelements from the soil, therefore the importance of foliar fertilization increased. Applied at the right time, foliar fertilization might increase the resistance of corn against biotic and abiotic factors as well. In the experiment the authors examined the effect of three foliar fertilizer products and their combinations on the important elements of the crop development of corn, and their application from economic point of view. The experiment was set in three repeats in random blocks on meadow soil in 2015. The nitrogen supply of the soil is good, the phosphorus and potassium supply is very good, however the zinc content of the soil is low. The corn yield without foliar fertilisation was 6.39 t/ha. The highest yields were achieved after the following treatments: Amalgerol + Fitohorm Turbo Zn (7.50 t/ha), Fitohorm Turbo Zn (7.35 t/ha), and Algafix + Fitohorm Turbo Zn (6.94 t/ha). Treatments with products containing Zn resulted in the best amounts of yields indicating that the low Zn levels of the ...
