“…The potential fertiliser use of compost will have no significant effect on a change in the quantitative relations of carbon, nitrogen and potassium in soil. One should, therefore, suppose that there will be no significant shift in the balance of transformations of those elements in the soil environment, in the direction of synthesis or mineralisation (Paul and Clark 1996, Kalembasa and Kalembasa 2015and 2016. Similar quantitative ratios of carbon to nitrogen and phosphorus are noted in spent mushroom substrate (Kalembasa et al 2012, Becher andPakuła 2014).…”

A b s t r a c t. The study addresses the problem of assessment of the chemical properties of compost produced on the basis of organic fraction of municipal waste, including the quantity and quality of organic matter. Six composts originating from central-eastern Poland were included in the research. The following analyses were performed: pH; salinity; content of C, N, P, K and heavy metals, fractional composition of organic matter (after decalcification, bitumens, fulvic acids, humic acids and post-extraction residue) and properties of humic acids (elemental composition and spectrophotometric properties). The analysed composts were characterised by a similar chemical nature. They were considered to be chemically and biologically silised. They were characterised by a significant potential for soil enrichment in soil humus and biogenic elements. The content of heavy metals in the tested composts did not constitute a barrier to their use as a fertiliser. The contribution of carbon of humic substances (separated by 0.1 M NaOH) ranged from 23.3 to 31.2%. Among humic substances the most humic acids prevailed, with the ratio of humic to fulvic carbon from 2.07 to 3.03. The elemental composition of humic acids of the tested composts was similar to those occurring in humus horizons of intensively used arable soils. Spectrophotometric parameters indicated a low degree of their humification.K e y w o r d s: compost, humic substances, humic acids

“…The nitrogen and carbon organic compounds were isolated from the soil material using a 2-step sequential extraction as described by Kalembasa (1995) and modified by Becher (2013), Becher et al (2023) and Kalembasa and Kalembasa (2016). According to the procedure mentioned above, the following fractions were obtained: a fraction of the soluble mineral and organic compounds, a fraction of the easily hydrolysable, difficult-to-hydrolyse and nonhydrolysable compounds.…”

Returning crop residue can increase soil organic matter content, and residue quality has an influence over the rate of their turnover. However, there is a lack of information concerning the biochemical transformations of organic compounds of N and C present in the crop residues during subsequent crop growth. In this study, the contents of organic N and C fractions in soils obtained using acid and alkaline hydrolysis under two crop rotations (faba bean vs. wheat rotation) were investigated. Black fallow served as a control. The mean total N increased in the order: black fallow, wheat rotation, faba bean rotation, total C and SOM were higher in the cropped soils than in black fallow. Hydrolysable-N (1-step acid hydrolysis) reached 83.7% total N, amino acid-N and threonine+serine-N were the highest in faba bean rotation and the lowest in black fallow, ammonia-N and aminosugar-N were lower in black fallow than in cropped soils. Hydrolysable-N (2-step sequential fractionation) reached 85.3% total N and significant differ ences were noted between the cropped soils and black fallow, with respect to both the N and C contents. 15 N was mainly accumulated in the N soluble and easily hydrolysable N compounds, and these fractions were greater in cropped soils than in black fallow. N in the humic com pounds increased from black fallow to faba bean rotation. A PCA analysis showed that crop rotation and soil sampling terms had a substantial influence over cluster formation. An ANOSIM test revealed significant diff erences between the crop rotation and term treat-ments. The results indicated that soil with faba bean rotation is richer in N compounds than soil with wheat as a forecrop and this may result in a reduction in N fertilizers for the succeeding crop.Ke y w o r d s: organic nitrogen fraction, soil organic matter, crop residues, faba bean, wheat, 15 N

“…After the addition of 5 mL of 10% HCl, crucible contents were passed through a hard filter to a 100 mL volume flask and supplemented with distilled water up to the mark. In the presence of hydrochloric acid, silicic acid was precipitated from silicates in the form of white gelatinous mass with high water content (H 2 SiO 3 •nH 2 O), which at a temperature of 100-200 • C converted into sparingly soluble SiO 2 [15]. The content of selected chemical elements was determined using Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES), while calibration was performed using standard Merck solutions.…”

This paper presents the results of research on the Ba, Li and Ti content in six species of herbs sampled from mid-field wet depressions and from the soil. These temporary flooded depressions were surrounded by arable crops, permanent grassland and shrubby vegetation. The research area was located in the eastern part of the Mazovian Voivodeship, east-central Poland. The following plants were used in the experiment: corn mint (Mentha arvensis L.), purple marshlocks (Comarum palustre L.), silverweed (Potentilla anserina L.), yarrow (Achillea millefolium L.), yellow loosestrife (Lysimachia vulgaris L.) and gypsy-wort (Lycopus europaeus L.). The Li, Ba and Ti content of plants, bottom sediment and soil was determined by the ICP-AES method after previous dry mineralization. Of the six herb species, Mentha arvensis L. was with the greatest accumulation potential of the chemical elements. However, no excessive Ba, Li and Ti content was found in herbs growing at different distances from arable fields, permanent grassland and shrubby vegetation. The highest Ba content was found in periodically flooded soil (zone II), while the highest amounts of Li and Ti were recorded in non-flooded soil (zone III).
