Opis:
Different individual soil parameters or simple indices are widely used in soil quality evaluation, but this approach has many limitations. The aim of the study was to determine an integrated soil quality index in agricultural soils as affected by different levels of anthropopressure. The soil quality index was calculated through: the selection of the appropriate indicators for a minimum data set, score assignation for selected indicators and the integration of indicators in an index. The study was carried out in two areas under agricultural use with similar soil cover but with a different history and intensity of exposure to pollution input. Soil samples collected from the surface layer (0-30 cm) were analysed for physicochemical (i.e. texture, fractional composition of soil organic matter, pH), and biological (respiration, dehydrogenase activity, microbial biomass and nitrification) properties and the levels of contaminants (16PAHs and heavy metals). The level of anthropopressure was assessed on the basis of pollutants emission indices. A statistical evaluation based on principal component analysis enabled the selection of indicators of significant importance to soil quality. The level of anthropopressure was found to be an important factor influencing soil quality; higher soil quality index values (0.50) were determined for the area of low anthropopressure.

Opis:
The efficient use of water is increasingly important and proper soil management, within the specificities of each region of the country, allows achieving greater efficiency. The South and Caparaó regions of Espírito Santo, Brazil are characterized by relief of ‘hill seas’ with differences in the degree of pasture degradation due to sun exposure. The objective of this study was to evaluate the least limiting water range in Udox soil under degraded pastures with two faces of exposure to the sun and three pedoenvironments. In each pedoenvironment, namely Alegre, Celina, and Café, two areas were selected, one with exposure on the North/West face and the other on the South/East face. In each of these areas, undisturbed soil samples were collected at 0-10 cm depth to determine the least limiting water range. The exposed face of the pasture that received the highest solar incidence (North/West) presented the lowest values in least limiting water range. The least limiting water range proved to be a physical quality indicator for Udox soil under degraded pastures.

Opis:
Soil quality is a measure of the condition of soil. The goal of sustainable agriculture is to maintain a non-negative trend in productivity while maintaining soil quality. Susukan is an area in Semarang, Central Java, Indonesia, which has developed organic farming to increase rice productiv- ity and quality. The main objective was to determine the sustainability of organic rice cropping sys- tems. The organic farming system at the research location has been conducted for 8 years. Appropri- ate agricultural management can maintain the quality of soil, environment and improve the health of plants, animals and humans. This research aims to know the soil quality and determine the minimum data set (MDS) in organic and non-organic paddy field with a technical irrigation system. Paddy soil samples were analyzed in the laboratory. The parameters are porosity, permeability, hydrogen potential (pH), cation exchange capacity (CEC), soil organic matter (SOC), total-N (nitrogen), car- bon/nitrogen (C/N) ratio, available-P (phosphorus), available-K (potassium), base saturation (BS), electric conductivity (EC), soil respiration (qCO2), redox potential (Eh) with 3 repetitions. The value of soil quality index (SQI) in the organic paddy field is 3.216 with bad soil quality criteria, while the non-organic paddy field is 0.147 with very bad criteria. The soil quality values are based on the key factors or MDS that is potential redox (EH), soil respiration (qCO2), potential hydrogen (pH), poros- ity, soil organic matter (SOC), total-N (nitrogen), C/N ratio, available-P (phosphorus).

Opis:
The present paper aims to perform a detailed analysis of all available results of physical and chemical testing of recultivated land, in order to determine which of them significantly influence their quality, and should thereby form the basic criteria for the evaluation and for the development of the methods of management of lands subject to recultivation. The samples of soil from Piaseczno dump area were tested. The test results have allowed to state that the method proposed by Gruszczyński, based on the physical properties of soil, with special respect to the water and air properties and sorption abilities, allows to properly evaluate the quality of such soil. The method allows also to take account of changes in soil quality, occurring as a result of the soil-creation process initiated by the recultivation.
Celem niniejszego opracowania było przeprowadzenie szczegółowej analizy wszystkich dostępnych wyników badań właściwości fizycznych i chemicznych gruntów rekultywowanych w celu ustalenia, które z nich mają istotny wpływ na ich jakość i tym samym powinny stanowić podstawowe kryteria oceny przy opracowaniu metodyki gospodarowania utworami podlegającymi rekultywacji. Badania przeprowadzono na próbach gruntów ze zwałowiska Piaseczno. Wyniki badań pozwoliły na stwierdzenie, że zaproponowana przez Gruszczyńskiego metoda, bazująca na właściwościach fizycznych gruntów, ze szczególnym uwzględnieniem właściwości powietrzno--wodnych oraz zdolności sorpcyjnych, umożliwia prawidłową ocenę jakości gruntów. Daje ona także możliwość uwzględnienia zmian jakości gruntów, zachodzących pod wpływem procesu glebotwórczego zainicjowanego w wyniku rekultywacji.

In the soil environment, there are many enzymeswhose origin is related to microorganisms. Enzymes participatein the synthesis of proteins and nucleic acids, they are also elementsof the carbon, nitrogen and phosphorus cycles. They alsoplay a role in less known cycles, such as the sulphur cycle orcellulose decomposition. Determination of soil enzymes activityis very popular in microbiology, biochemistry and agriculturalsciences. Their activity may be a measure of soil fertility. Thepresent report describes the importance of selected soil enzymesand the methods of their determination. However, it is importantto remember that a single enzyme cannot be an indicator of theenvironment. The enzymatic activity is sensitive to many naturaland anthropogenic factors affecting soil microorganisms. Onlycomprehensive researchers on the activity of many, different enzymescan provide reliable information on the state of the soilenvironment.

Opis:
Soil microorganisms play a key role in many biochemical processes essential for the environment and for the ecological and production functions of soils, hence they are very important quality indicators. The study aimed at evaluating the effect of 1 and 2% additions of wheat and miscanthus straw biochars on soil enzymatic activity (dehydrogenases, urease, phosphatases) and the number of microorganisms (bacteria, fungi, actinobacteria). Pot experiments were carried out on soil with a loamy sand texture. The geometric mean of enzyme activities, biological index of fertility, and the integrated total enzyme activity index were used to explore the relationships between soil enzyme activities and the microbiological and chemical properties of soil. The addition of 1% miscanthus straw biochar had the most beneficial effect on the number of bacteria and fungi (increase by 380 and 26%, respectively), and 1% wheat straw biochar on the number of actinomycetes (increase by 273%). The correlation analysis between the number of actinomycetes and the chemical parameters of the soil showed the significant effect of the content of Ntotal (r = 0.76) and Ctotal (r = 0.85). The values of biological index of fertility, total enzyme activity index and geometric mean of enzyme activities indexes showed that the best quality of soil was produced by a 2% addition of wheat straw biochar.

Opis:
The aims of this study were to assess the quality of soils affected by strongly saline waste products and to analyze the spatial distribution pattern of soil properties influenced by a soda plant. Soil samples were analyzed for electrical conductivity (EC), sodium adsorption ratio (SAR), pH, trace element content and dehydrogenases activity. The research was conducted in the vicinity of the waste ponds of the Ciech Soda Poland S.A. company (Central Poland), where 35 groundwaters, 63 surface (0–20 cm) and 60 subsurface (80–100 cm) samples were collected. Although the waste ponds are currently not used for regular disposal of waste products, a high level of salinity of groundwater and soil, especially in the subsurface layer, is still being observed. The electrical conductivity of soil saturation extract (ECse) values varied between 0.9–15.4 and 1.0–87.2 dS·m-1 for surface and subsurface layer, respectively. Analysis of the spatial distribution of soil salinity reveals a correlation with microrelief and groundwater levels. Maps of the spatial distribution of heavy metals showed that their content in the subsurface layer was a result of chemical migration from the waste ponds, and in the surface layer by other sources (atmospheric deposition). The soil salinity did not influence dehydrogenases activity.

Opis:
In this review paper strip-till has been characterized from the point of view of the latest scientific research and practi- cal justification of the advisability of using and popularizing this cultivation method in Poland for various crop species. Analysis of scientific literature has shown that strip-till has a beneficial ef- fect on crops and soil properties. It reduces the number of tillage operations, and thus labour costs and fuel consumption. Further improvement of strip-till cultivation should be related to the im- provement of seeding units designed for this cultivation technol- ogy, as well as to the implementation of precision farming solu- tions related to the application of fertilizers and their effective use by plants. In connection with the implementation of cultivation technologies improving soil quality and reducing the negative im- pact of agriculture on the environment, strip-till technology has a chance to be much more widely used in Poland and may replace traditional plough tillage.

Opis:
One of the bioindicators most often applied to assess the quality of soil is its enzymatic activity. Undesirable changes in the activity of enzymes can imply excessive presence of substances which are harmful to soil environment, such as heavy metals. Being a heavy metal, zinc is also an element essential for maintaining proper functions of live organisms. The purpose of this study has been to determine the significance of changes occurring in moderately heavy soil under the influence of zinc. The experiment was carried out in three replicates under laboratory conditions. Sandy loams of pH 5.5 and 7.0 were used for the trials. The soils were contaminated with zinc according to the following design: control (natural content), raised content (70 mg Zn2+ kg–1), weakly polluted (200 mg Zn2+ kg–1 ), moderately polluted (500 mg Zn2+ kg–1), heavily polluted (1,500 mg Zn2+ kg–1) and very heavily polluted soil (5,000 mg and 10,000 mg Zn2+ kg–1). The soil samples prepared as above were brought to the moisture content of 50% maximum water capacity and incubated at 25oC for 120 days. On day 30, 60 and 120, the activity of dehydrogenases, β-glucosidase, urease, acid phosphatase and arylsulphatase was determined. Based on these determinations, the following indices were calculated: ED50, the index for resistance (RS) and the index for resilience (RL). The tests have demonstrated that as the rate of soil contamination with zinc increased, the activity of all the analyzed enzymes was significantly depressed. The negative influence of zinc contamination on the activity of particular enzymes, irrespective of the soil pH, persisted throughout the whole experiment. In respect of their sensitivity to zinc, the enzymes can be ordered as follows: arylsulphatase > dehydrogenases > acid phosphatase > urease > β-glucosidase. Zinc contamination caused lasting changes in the soil environment, but the return to the state of equilibrium was the quickest in the case of dehydrogenases (RL = 0.276), less rapid for arylsulphatase (RL = 0.173) and the slowest for acid phosphatase (RL = 0.064). In contrast, the activity of urease, instead of regenerating, was increasingly disturbed (RL = 0.350). Soil acidification was the factor that most evidently exacerbated the negative influence of zinc on the activity of β-glucosidase and arylsulphatase. Values of ED50 for the activity of particular enzymes were varied. In the soil of pH 7.0, they ranged from 3,324 mg Zn2+ kg–1 for β-glucosidase to 412 mg Zn2+ kg–1 for dehydrogenases, and in the soil of pH 5.5, they varied from 1,008 Zn2+ kg–1 for β-glucosidase to 280 mg Zn2+ kg–1 for arylsulphatase.
Aktywność enzymatyczna gleby stanowi jeden z najczęściej wykorzystywanych biowskaźników do oceny jakości gleby. Niekorzystne zmiany w aktywności enzymów mogą świadczyć o nadmiernej zawartości substancji szkodliwych dla środowiska glebowego, do których należą również metale ciężkie. Cynk jest też niezbędnym składnikiem do prawidłowego funkcjonowania organizmów żywych. Celem badań było określenie istotności zmian zachodzących w glebie o średniej kategorii agrotechnicznej ciężkości pod wpływem cynku. Doświadczenie wykonano w warunkach laboratoryjnych, w 3 powtórzeniach. Do badań wykorzystano gliny piaszczyste o pH 5,5 oraz o pH 7,0, które zanieczyszczono cynkiem wg następującego schematu: kontrola (zawartość naturalna), zawartość podwyższona (70 mg Zn2+ k g–1), słabe zanieczyszczenie (200 mg Zn2+ k g–1), średnie zanieczyszczenie (500 mg Zn2+ k g–1), silne zanieczyszczenie (1500 mg Zn2+ k g–1) i bardzo silne zanieczyszczenie (5000 mg oraz 10 000 mg Zn2+ k g–1). Tak przygotowane próbki gleby uwilgotniono do poziomu 50% maksymalnej pojemności wodnej i inkubowano w temp. 25°C przez 120 dni. W 30., 60. oraz 120. dniu określono aktywność dehydrogenaz, β-glukozydazy, ureazy, fosfatazy kwaśnej oraz arylosulfatazy. Na ich podstawie obliczono wskaźniki ED50, oporności (RS) i powrotu do równowagi (RL). W wyniku badań stwierdzono, że wraz ze zwiększeniem stopnia zanieczyszczenia gleby cynkiem aktywność wszystkich badanych enzymów ulegała istotnemu zmniejszeniu. Negatywny wpływ zanieczyszczenia cynkiem na aktywność enzymatyczną gleby, niezależnie od jej pH, utrzymywał się przez cały okres trwania badań. Enzymy pod wpływem wrażliwości na zanieczyszczenie gleby cynkiem można uszeregować następująco: arylosulfataza > dehydrogenazy > fosfataza kwaoena > ureaza > β-glukozydaza. Zanieczyszczenie cynkiem powodowało długotrwałe zmiany w środowisku glebowym, ale najszybciej do stanu równowagi powracały dehydrogenazy (RL = 0,276), nieco wolniej arylosulfataza (RL = 0,173), i najwolniej fosfataza kwaoena (RL = 0,064). Natomiast aktywność ureazy nie tyko nie regenerowała się, ale stan zaburzenia ulegał pogłębieniu (RL = -0,350). Zakwaszenie gleby w największym stopniu wzmagało negatywne działanie cynku na aktywność β-glukozydazy i arylosulfatazy. ED50 dla aktywności poszczególnych enzymów było zróżnicowane. W glebie o pH 7,0 wahało się od 3324 mg Zn2+ k g–1 dla β-glukozydazy do 412 mg Zn2+ k g–1 dla dehydrogenaz, a w glebie o pH 5,5 od 1008 mg Zn2+ k g–1 dla β-glukozydazy do 280 mg Zn2+ k g–1 dla arylosulfatazy.
