Opis:
Technological progress in the cultivation of horticultural and fruit plants makes the use of soil becoming less and less important. Growing plants in soilless substrates is becoming more and more common. The aim of the study was to determine the variability of the mineral composition of fruits and leaves of everbearing strawberry of the San Andreas® variety in soilless cultivation. Research was carried out at the experimental plantation of Polski Instytut Truskawki Sp. z o.o. (geographical coordinates: 50°02′11″N and 19°81′19″E). The cultivation of everbearing strawberry of the San Andreas® variety was carried out in a gutter system under covers in coconut substrate. The stability of the chemical composition of strawberry leaves and fruits depends on fertilisation, weather factors, and the quality of water used for fertigation. Despite maintaining the content of nutrient in the rhizosphere at the level recommended for organic substrates, low potassium and calcium content and high magnesium content in strawberry leaves were determined. Among the macroelements analysed in strawberry leaves, the lowest variation coefficient values were found for nitrogen, magnesium and calcium, and in fruits – for nitrogen, phosphorus, and magnesium. The highest variation coefficients were obtained for phosphorus and sodium in strawberry leaves, and for sulphur and sodium in strawberry fruits. Variation coefficient values of copper, zinc, and manganese content in leaves were similar. The content of iron in leaves and zinc in fruits was characterised by the lowest variation coefficients during the growing period.

Opis:
The impact of lignite and leonardite combined with a NaX-C composite on the abundance of selected groups of culturable microorganisms in soil contaminated with Pb, Cd and Zn was tested. For this purpose, a 7-month incubation experiment and two-year pot experiments were conducted. The pattern of both experiments was analogous and included: soil without fertilization (C); soil fertilized with NPK mineral fertilizers (MF); soil with NPK + 3 or 6% lignite (MF+CW3%, MF+CW6%) and 3% zeolite-carbon composite (NaX-C); soil with NPK + 3 or 6% leonardite (MF+CL3%, MF+CL6%) and 3% zeolite-carbon composite (NaX-C). The test plant in the pot experiment was the Kosynier variety of maize. The soil material was used to estimate the abundance of general bacteria, mold fungi, actinomycetes (actinomycetales), ammonification bacteria and bacteria from the Azotobacter genus. The study found that the application of lignite and leonardite combined with a NaXC composite had generally contributed to a significant increase in the total nitrogen content and a decrease in the total carbon content in soil in the pot experiment. In general, the mineral-organic mixtures had a stimulating effect on the analyzed groups of soil microorganisms in both experiments, but the dominant groups in the pot experiment were total bacteria and ammonifying bacteria, while in the incubation experiment, fungi and actinomycetes were the prevalent groups. An RDA analysis indicated that mold fungi, bacteria, actinomycetes and amminofers were positively correlated with the EC, total nitrogen and carbon.
