Opis:
The aim of the research was to test of several variants of basalt-sulphur improver, differing in the ratio of the two components, and to select the most suitable one for oil seed rape. Basalt dust, which is a troublesome by-product of rock processing, and elemental sulphur were used to produce the improver. The study included 3 improver variants with 1, 1.5 and 2% S and a control treatment without an improver. The experiment was conducted in concreted microplots filled with two soils: sandy loam and loamy sand, in a split-block two-factor design, in 4 replicates. The most suitable variant for rapeseed was the variant containing 1.5% S, which resulted in a 12% increase in rapeseed yield on sandy loam. Moreover, for this variant, an increase in seed fat content, an increase in the bioavailable form of sulphur in the soil and an increase in the concentration of this nutrient in oilseed rape straw and seed were observed on both soils.

atmospheric nitrogen fixation
Opis:
Bacteria belonging to the genus Azotobacter are microorganisms commonly found in various soils all over the world and capable of fixing atmospheric nitrogen. The biological nitrogen fixation (BNF) process annually supplies approximately140–170 million tons of this element to the nitrogen cycle, which is of great importance from an ecological and practical point of view. Although the efficiency of atmospheric nitrogen fixation by Azotobacter spp. is relatively high and amounts to 20 mg N per1 g of glucose used, these bacteria are sensitive to various environmental factors, including soil reaction, contents of organic matter, soil humidity or nutrient content, and their abundance in soils is small. These bacteria secrete numerous biologically active substances into the soil environment, which have a beneficial effect on the development of plants, which from the ecological point of view plays an important role in the functioning of agricultural ecosystems. An additional advantage of bacteria belonging to the genus Azotobacter, which speaks for their use in agriculture, is the ability to produce antifungal and solubilization of insoluble phosphates. Research on Azotobacter spp. proves that the concentration of hydrogen ions (pH) is a significant factor which determines the presence of this group of bacteria in the soil environment. Many other soil properties have a large impact on the presence and development of this important agricultural group of bacteria. The aim of the work was to systematize the knowledge on the known occurrence conditions and ecological relationships and interactions between environmental factors and the presence and abundance of Azotobacter bacteria in soils.

Opis:
Coal mining in Donbas is a global problem as it causes the destabilization of ecological landscapes. Spoil tips, covering almost 52% of the territory, alter the topography of the land, affect the ecosystem, and decrease soil fertility. The soils become degraded and are unsuitable for agricultural use. The occupation of the Donetsk region by the Russian Federation has suspended the observation and research of man-made influence on this territory, which is a major concern for the scientific community. To reduce the negative impact of spoil tips, it is necessary to slow down the process of pyrite oxidation and the formation of toxic substances, as well as the migration of heavy metals due to erosion. Biological reclamation with grass and woody plants can help in achieving this goal. Another urgent issue is the constant supervision and assessment of the suitability of the bedrock of coal mines for agricultural use. The study investigated the total and mobile content of heavy metals in the rock samples from the “South Donbaska-1” mine, ordinary chernozem (background soil), and vegetation growing on the spoil tip. The results showed that the content of Co, Cr, Cu, and Fe in the rock of the spoil tip is higher than in the background soils. The content of heavy metals gradually decreases as the distance from the spoil tip increases. The content of Pb in ordinary chernozem and rock is practically the same, indicating its active migration. An analysis of the biomass of plant samples growing on the spoil tip showed that the content of Co, Cu, and Zn was within the limits of the threshold limiting values. However, the content of other studied elements exceeded the permissible norms. The research results provide information on the ecological state of the spoil tip and can be used for recreational as well as reclamation works in these areas.

Opis:
In 2017 the field experiments were established at two localities of the South-west Slovakia (1 Dolná Streda: sandy Arenosol and 2 Veľké Úľany: loamy Chernozem). The experiments involved biochar substrates (1 BS1 mix biochar, sheep manure and 2 BS2 mix biochar, sheep manure and digestate) in two application doses (10 and 20 t ha-1), which were applied independently compared with the unfertilized control (Co-NF) and combined with additional fertilization versus the fertilized control (Co-F), in order to verify their impacts on the changes of soil properties. In the spring and autumn of 2018–2020, within these experiments the soil samples were taken to determine the range of effect of the tested biochar substrates (BS) and also their combination with fertilization (F) on the changes of soil pH and surface charge of soil particles in the soils different in texture. The results pointed out the fact that a more significant effect of tested BS on soil pH was detected in sandy soil than loamy soil. In sandy soil, only the application of BS2 in doses 10 and 20 t ha-1 statistically significantly increased the soil pH in H2O in comparison with Co-NF. The application BS1 + F in dose 10 t ha-1 and BS2+F in dose 20 t ha-1 statistically significantly increased pH in KCl compared with Co-F. The fertilization to BS eliminated the considerable decrease of the soil pH in H2O both soils. In sandy soil, pH was substantially regulated by the content of alkali cations themselves in BS; however, in loamy soil, it occurred as a result of the increase of the content of soil organic carbon after the application of BS (R2 = 0.339), but also BS + F (R2 = 0.468). In sandy soil, the application of BS itself, owing to the change of the surface charge, influenced predominantly the sorption of anions. Conversely, the additional fertilization to BS treatments had an impact on the sorption of cations. In loamy soil, the application of BS and BS + F as a result of the change of surface charge did not have any significant effect on the total soil sorption.

Opis:
Soils along with their properties, climate and mineral fertilisation level are among the most important environmental elements impacting the quality and quantity of agricultural crops. Agricultural practices as well as crop varieties also have an impact on crop quantity and quality, but the method of cultivation of agricultural crops and selection of varieties depend on soil quality and local climate conditions. One of the most important soil parameters is pH. Acidic soils result in a range of negative phenomena that, on the one hand, impact crop quality and quantity, while, on the other hand, place a burden on the natural environment. Most soils used for crop cultivation in Poland originated from noncarbonate rocks and, consequently, are acidic. In order for agricultural production to reach an appropriate level of economic efficiency, systematic deacidifying fertilisation should be applied. However, the level of deacidifying fertilisation in Poland is far too low relative to the requirements of most plants. The necessity of using deacidifying fertilisers in crop production is a known problem and has been described in both scientific and popular scientific literature. Nevertheless, current trends indicate that farmers still use deacidifying fertilisation to a small extend, despite the fact that it is a simple way to significantly increase the quality and quantity of agricultural crops while maintaining the same level of fertilisation by mineral fertilisers. The paper describes, based on the National Agricultural Census 2012-2022, the current level of soil fertilisation by deacidifying fertilisers in Poland and analyses the reasons for this level as well as potential consequences.

Opis:
Soil Erodibility Factor (K-factor) is a crucial component of a widely used equation for soil erosion assessment known as the USLE (Universal Soil Loss Equation) or its revised version – RUSLE. It reflects the potential of the soil of being detached due to rainfalls or runoffs. So far, an extensive number of researches provide different approaches and techniques in the evaluation of K-factor. This study applies soil erodibility estimation in the soils of the South Caucasian region using soil data prepared by the International Soil Reference and Information Centre (ISRIC) with 250 m resolution, whereas the recent K-factor estimation implemented in the EU scale was with 500 m resolution. Soil erodibility was assessed using an equation involving soil pH levels. The study utilises Trapesoidal equation of soil data processing and preparation, as suggested by ISRIC, for various layers of surface soil data with up to 0-30 cm depth. Both usage of SoilGrids data and its processing as well as estimation of K-factor applying soil pH levels have demonstrated sufficient capacity and accuracy in soil erodibility assessment. The final output result has revealed the K-factor values varying from 0.037 and more than 0.060 t ha h/MJ mm within the study area.

This study investigated the spatial variability of the soil silicon content in relation with topography, parent materials, soil texture, soil organic matter, exchangeable cations and pH. Using the experimental data from two longterm sites in the Forest-Steppe area of Ukraine, the SiO2 content was estimated in 60 samples taken from a soil depth 0–25 cm. The accumulation of SiO2 was significantly greater in the soils formed in footslopes. A content of extractable silicon fraction significantly increased from a sandy loam(366–465 mg•kg-1) to medium(670–697 mg•kg-1) and heavy(506–849 mg•kg-1) textured soils. The highest amount of available silicon content was found in the soils containing: 35.0–39.9% of physical clay fraction (< 0.01 mm dia) in Hrytsiv area – 143.0 ± 46 mg•kg-1 and < 25.0% of physical clay fraction in Khrolyn area – 125.0 ±6 mg•kg-1. A significant relationship was found between pHKCl, P2O5, K2O, Mg and both forms of SiO2. There was almost no correlation between available/ extractable SiO2 and exchangeable Ca and ∑ Ca+Mg. Our studies found the best correlation between extractable SiO2 and spring barley yield (r = 0.651; P = 0.041), as well assoluble SiO2 and corn for grain yield (r = 0.514; P = 0.128). No significant relationships were found for sugar beet, winter wheat, sunflower.

Opis:
During biogas production, anaerobic digestion of plant material rich in nutrients results in the so-called whole digestate. e application of nutrient-rich material present in digestate could have fertilising effects, especially in intensively used agricultural soils, and in crop yields that can affect the nutrient cycle. e aim of this article is to inform about possibilities of using mixture of digestate and haylage (use the fertilizing effect of both matters), and at the same time contribute to the improvement of agrochemical properties of soil. is study evaluates the effect of applying the mixture of digestate and haylage on germination and early stages of plant development. is article deals with primary test mixtures of digestate and haylage at ratios 10:1, 5:1 and 3:1 and compares the results with whole digestate applications. Simplified statistically calculated quantities showed that all examined mixtures better fertilizing effect in comparison with the control growing media. Based on the chemical analysis of the growing medias, a growing media with mixtures of digestate and haylage characterizing as growing medias with a high content of nutrients and a low amount of hazardous metal was investigated. e examined growing media thus met the limits for organic and commercial fertilizers. Fertilizing effects of growing media with mixture of digestate an haylage can also be noted on increasing the proportion of macronutrients in the soil, reducing fertilization only throughout whole digestate.
Podczas produkcji biogazu fermentacja beztlenowa bogatego w składniki pokarmowe materiału roślinnego skutkuje powstaniem tzw. pofermentu. Zastosowanie materiału bogatego w składniki odżywcze obecnego w pofermencie może mieć działanie nawozowe, zwłaszcza dla intensywnie użytkowanych gleb rolniczych oraz dla plonów, może wpływać na cykl składników odżywczych. Celem artykułu jest przedstawienie możliwości wykorzystania mieszanki pofermentu i sianokiszonki (wykorzystanie efektu nawozowego obu substancji), a jednocześnie przyczynienie się do poprawy właściwości agrochemicznych gleby. W pracy oceniono wpływ zastosowania mieszanki pofermentu i sianokiszonki na kiełkowanie i wczesne etapy rozwoju roślin. Artykuł dotyczy podstawowych mieszanek testowych pofermentu i sianokiszonki w proporcjach 10:1, 5:1 i 3:1 i porównuje wyniki z zastosowaniem całego pofermentu. Uproszczone statystycznie obliczone ilości wykazały, że wszystkie badane mieszanki mają lepsze działanie nawozowe w porównaniu z kontrolnymi podłożami uprawowymi. Na podstawie analizy chemicznej podłoży uprawowych zbadano podłoża uprawowe z mieszaniną pofermentu i sianokiszonki, charakteryzujące się jako podłoża uprawowe o wysokiej zawartości składników odżywczych i niskiej zawartości metali niebezpiecznych. Badane podłoża uprawowe spełniały tym samym limity dla nawozów organicznych i komercyjnych. Nawozowe efekty podłoży uprawowych mieszanką pofermentu i sianokiszonki można również zauważyć na zwiększenie udziału makroskładników w glebie, ograniczając nawożenie tylko w samym pofermencie.

Chemical fertilizer use is highly increasing in farming activity, and the process has a significant impact on soil quality and pH which is the measurement of the acidity or alkalinity. Therefore, soil pH is the main variable because it regulates plant nutrition availability by controlling the chemical forms of various nutrients in agricultural activity. This research aims to find out the excessive use of chemical fertilizers & dynamic soil pH on agricultural land. The primary data had collected by using questionnaires, interviews, Focus Group Discussion (FGD) and soil testing. For the soil testing experiment, simple random sampling method was used to collect the sample in 11 agricultural continents using GPS technology to identify the land location and 22 soil samples were collected based on pre and post applied chemical fertilizer stage. In order to pH value were tested from the collected soil samples. Accordingly, the data were analyzed by ArcGIS 10.3 using the IDW technique. Therefore, the results find out the condition of soil quality during the pre-chemical fertilization, 9% of the land found to be slightly acidic, 27% of the land with neutral soil structure and 15% of the land with salinity soil structure. During the post-chemical fertilization, 9% of the land was found to be moderately acidic, 41% of the soil was found to be strongly acidic, 32% of the soil highly acidic and 18% of the land be moderately pH. The result of the study shown, chemical fertilizers use highly impact on soil quality and agricultural land productivity.

Opis:
Since tillage technologies considerably influence soil properties and have a major impact on soil sustainability, the objective of this study was to evaluate the effects of conventional (CT) and reduced (RT) tillage on basic soil chemical properties at selected Slovak agricultural farms. Subsequently, the relationships between the chemical properties and soil organic matter (SOM) in both tillage technologies were ascertained. Differences in soil properties between long-term RT and CT were investigated at the adjacent plots on thirteen sites, where six soil pits were excavated on each RT and CT plots. Soil samples were collected from all pits, for each 0.1 m layers from the depth of 0.0-0.4 m. The results revealed that the regular overturn of topsoil, and thus the transfer of leached base cations to the surface layer, as well as deeper incorporation of crop residues and fertilizers in the soil cultivated conventionally has been manifested by higher values of pH, lower hydrolytic acidity (H) and the almost uniform content of base cations (mainly in the layer 0.0-0.3 m) compared to the soil cultivated by RT. Apart from H,, none of the examined sorption properties and pH differed significantly between the compared tillage technologies. Therefore, H can be considered as an important indicator of the change of basic chemical soil characteristics. While in RT, there was a significant correlation only between labile SOM fractions and basic soil chemical properties, in CT the sorption parameters and pH were influenced by labile and also stable SOM.

Opis:
The progressive degradation of soils is a recently increasing environmental problem. The risk of soil degradation may be associated, for example, with landslides, flooding, soil erosion. However, these are relatively rare phenomena compared to the risk of chemical degradation caused by human activity. Given the limited research on the positive effect of miscanthus biochar on soil properties, a study was carried out aimed at determining changes in pH, electrical conductivity, sorption properties, and mobility of selected heavy metals in sandy soil treated with various chemicals. Biochar used in the study was produced at a temperature of 300°C. The addition of biochar to soil generally increased the pH value, regardless of the type of chemical degradation. The study revealed a decrease in the hydrolytic acidity value and, at the same time, no significant changes in the content of alkaline cations and sorption capacity of the biochar-treated soil. The best effect on reducing the mobility of trace elements was achieved by adding biochar to the soil supplemented with acidifying substances. Bearing in mind the current agricultural and environmental problems, there is a need to increase the effectiveness of biochar and to direct its action to improve specific soil properties.

The study was conducted in the Górzno and Czarny Bryńsk Forest, ranges which belong to the Brodnica Forest Dis-trict. Brunic Arenosol (Dystric) soils predominate in the Brodnica Forest Division (over 77% of the total area). The aim of this study was to analyze the granulometric composition, the organic matter content and pH values in H2O and KCl at three genetic horizons of soils (A – humus, B – sideric and C – parent material) within the crown extension of four tree species: English oak, European beech, Scots pine and Norway spruce. Silt and clay had a signifi-cantly higher share of A-horizon compared with B and C hori-zons. Soil samples collected under the crowns of Norway spruces were characterized by a significantly higher percentage of sand and a significantly lower percentage of silt than soil samples col-lected under beech and pine trees. In the analyzed soil horizons, pH values increased significantly with depth regardless of tree species. Tree species had a significant effect on the pH of the analyzed soils and the organic matter content of A horizon. Soil samples collected under the crowns of Norway spruces had sig-nificantly lower pH values than those collected under pine trees. Soil samples collected under the crowns of Norway spruces had significantly higher organic matter content than those collected under oak trees. There was a very high negative correlation be-tween organic matter content and the values of pH measured in 1 M KCl, and a high negative correlation between organic matter content and the values of pH measured in H2O suspension.

Opis:
This study presents the spatial variability and dynamics of soil organic carbon (SOC), soil organic matter (SOM) and soil pH contents at the Wonji Shoa Sugar Estate (WSSE), Ethiopia. Soil samples were collected immediately after the sugarcane was harvested and then analysed for SOC, SOM and pH content using standard procedures. The analysis results showed that the pH value varied between 6.7–8.4 (neutral to moderately alkaline) and 7.3–8.5 (neutral to strongly alkaline) for the top and bottom soil profiles, respectively. The SOM content is in the range of 1.1–6.7% and 0.74–3.3% for the upper and lower soil layers, respectively. Nearly 45% of the samples demonstrated a SOM content below the desirable threshold (<2.1%) in the bottom layer and, hence, inadequate. Moreover, most of the topsoil layer (95%) has an SOM content exceeding the desirable limit and hence is categorized within the normal range. Interestingly, the SOC content showed a spatial variability in both the surface and sub-surface soil layers. A lower SOC and SOM content was found for the sub-soil in the south and southwestern part of the plantation. A further decline in the SOC and SOM content may face the estate if the current waterlogging condition continues in the future for a long period. Overall, the study result emphasizes the need to minimize the pre-harvest burning of sugarcane and action is needed to change the irrigation method to green harvesting to facilitate the SOC retention in the soil and minimize the greenhouse emission effect on the environment, hence improving soil quality in the long-term.
W pracy przedstawiono przestrzenną zmienność i dynamikę węgla organicznego w glebie (SOC), materii organicznej (SOM) i pH na plantacji Wonji Shoa Sugar Estate (WSSE) w Etiopii. Próbki gleby były pobierane bezpośrednio po zbiorze trzciny cukrowej. Analizowano w nich wymienione wyżej składniki według standardowych procedur. Wartość pH zmieniała się od 6,7 do 8,4 w powierzchniowej warstwie gleby i od 7,3 do 8,5 w głębi profilu glebowego. Zawartość materii organicznej wynosiła od 1,1 do 6,7% w górnej i od 0,74 do 3,3% w dolnej warstwie gleby. Około 45% próbek zawierało materię organiczną w ilościach mniejszych niż pożądana (2,1%) w głębszych warstwach gleby. Większość próbek powierzchniowych zawierała materię organiczną w ilościach przekraczających tę granicę, co klasyfikuje te gleby jako normalne. Co ciekawe, zawartość węgla organicznego cechowała zmienność przestrzenna zarówno w powierzchniowych, jak i podpowierzchniowych warstwach gleby. Mniejszą zawartość materii organicznej i węgla organicznego stwierdzono w podpowierzchniowych warstwach gleby z południowej i południowozachodniej części plantacji. Gleby na plantacji mogą doświadczać dalszego spadku zawartości SOC i SOM, jeśli obecne wysycenie gleby wodą będzie występowało w przyszłości. Podsumowując, wyniki badań wskazują na potrzebę minimalizowania opalania trzciny cukrowej przed zbiorem oraz podejmowania działań zmierzających do zmiany metod nawadniania, aby usprawnić retencję węgla organicznego w glebie i łagodzić środowiskowe skutki emisji gazów cieplarnianych, a przez to polepszyć jakość gleb w dłuższej perspektywie czasowej.

Opis:
The pH dependence of adsorption reactions of cationic metals is due, in part, to the preferential adsorption of the hydrolyzed metal species, in comparison to the free metal ion (McBride, 1977; McLauren and Crawford, 1973; Davis and Leckie, 1978; Farrah and Pickering, 1976a,b; James and Healy, 1972; McBride, 1982; Cavallaro and McBride, 1980; Harter, 1983). The pH of the soil system is a very important parameter that directly influences sorption/desorption, precipitation/ dissolution, complex formation, and oxidation-reduction reactions. In general, maximum retention of cationic metals occurs at pH>7 and maximum retention of anionic metals occurs at pH<7. However, because of the complexity of the soil-waste system, with its myriad of surface types and solution composition, such a generalization may not hold true. For example, cationic metal mobility has been observed to increase with increasing pH due to the formation of metal complexes with dissolved organic matter.

Opis:
Biochar usually has a neutralizing effect, therefore, it is recommended for application to acid soils due to its potential to increase soil pH. The aims of this study were (1.) to quantify the role of different rates of biochar and biochar in combination with N fertilization on change of soil pH, and (2.) to evaluate the dynamic changes of soil pH in relation with doses of biochar and biochar with N fertilization. A field experiment was conducted with different biochar application rates: B0 control (0 t ha-1), B10 (10 t ha-1) and B20 (20 t ha-1) and 0, 40 and 80 kg N ha–1 of nitrogen fertilizer (N0, N40, N80) on silt loam Haplic Luvisol at the locality of Dolná Malanta (Slovakia) in 2014. Their effects were investigated after vegetation season of spring barley and spring wheat (once a month: from April to July) in 2014 and 2016, respectively. Experimental results indicate that the soil pHH2O in B0N0, B10N0, B20N0, B10N40, B20N40, B10N80 and B20N80 were 6.23, 6.45, 6.60, 6.77, 6.48, 6.36 and 6.60, respectively. The results of LSD test showed statistically significant differences between soil pH in control treatment and treatments with biochar and biochar with N fertilization. The most significant effect on increase of soil pH was observed in B10N40. During whole period, after application of biochar and biochar with N fertilization the values of pHKCl were gradually decreased in all treatments.
