Opis:
This study used multivariate statistics including cluster analysis (CA) and principal component analysis (PCA) to evaluate the variability and key indicators causing changes in soil quality in Tram Chim National Park, Dong Thap province, Vietnam. Soil samples were collected in the dry season at the habitats of Ischaemum rugosum (CM), Panicum repens (CO), Nelumbo nucifera (LS), Eleocharis dulcis (NO), Oryza rufipogon (LM), Rice field (RL), Melaleuca cajuputi (T) in two layers: A (0–20 cm) and B (20–40 cm). The parameters of pH, total nitrogen (TN), total phosphorus (TP), total acidity (TA), organic matter (OM), total iron (Fe) and exchanged aluminum (Al3+) were used to assess soil quality. The results showed that soil pH was low in both A and B layers. Fe and Al were both high, and the concentrations of these metals in layer A were higher than those in layer B. The OM content was medium while the TN and TP levels were very low. Most of the soil quality indicators tended to decrease with the depth (except for TA). The results of CA analysis showed that there was almost no major change in soil quality between the two soil layers; however, the soil quality in rice field habitat was different from other habitats. The cause may be due to human impact in adding fertilizers/pesticides during farming practices. The PCA results showed at least five influencing factors, explaining 99.7% and 99.9% of soil quality variation in A and B layers. The Al3+, TA, OM, and TP parameters had the main influence on the soil quality of layer A. Meanwhile, the pH, Al3+, TA, TN, Fet indicators had influence on the soil quality of layer B. These indicators need to be future surveyed to assess the evolution of soil quality in the study area.

Opis:
Peculiarities of formation, distribution and fertility of typical chernozems on the territory of Europe as a whole and within the agricultural lands of Ukraine were given. It is noted that the existing agro-industrial characteristics of agricultural products least reflect the quality of raw materials and therefore are not analyzed as a factor influencing public health. The relevance of biogeochemical research of food (agricultural) raw materials and the introduction of new criteria for its quality were outlined. The purpose of the presented research was to expand the quality indicators of agricultural products on the basis of topical structure of agricultural landscapes and biogeochemical criteria for evaluating "typical chernozems – cereals and vegetables" systems. A system of biogeochemical parameters and quality criteria of plant products containing two components has been developed. The first component is the spatial differentiation of natural and agro-technological features of agrolandscapes (systems of rocks-typical chernozems-cultures), which highlight the prevalence of nutrients in bedrock, particle size distribution of typical chernozems and the ratio of their prevalence within the administrative regions of Ukraine. There are 12 groups of agricultural landscapes that differ in these features. A set of biogeochemical parameters for the distribution of essential elements in the components of the agricultural landscape, criteria for their ecological balance and impact on the quality of agricultural raw materials.Implementation of the proposed criteria for the quality of agricultural products was carried out on the territories of two agrolandscapes of typical chernozems in the Kyiv and Poltava regions.It was established that the physico-chemical balance of Zn, Cu and excess Mo in the rocks and soils of the agro-landscape of the Right Bank Forest-Steppe is not consistent with biogeochemical deficiency of copper and, in part, zinc in cereals (oats). The physico-chemical balance of Zn, Cu in the soils of the agro-landscape of the Left Bank Forest-Steppe does not agree with the biogeochemical deficiency of zinc in vegetable crops (potatoes, carrots, and beets). On the basis of the biogeochemical criteria for the distribution of Zn, Cu, Mo in agricultural landscapes, the proposed territorial measures to improve the quality of grain and vegetable products to prevent copper and zinc "hidden hunger" in the population.

Opis:
The aim of the research was to identify the influence of environmental factors inherent in the alluvial and displaced sands of the study region on the growth of the Jack pine and the prospects for its cultivation. We found that the success of growth of Jack pine seedlings on sandy soils depends on a set of factors, which include the presence or absence, in the rhizosphere of sand, of humus impurities and genetic horizons of zonal soils, silty or loamy layers, soil density and composition of pine stands formed in the cultivation. On alluvial sands, sparse forests of Jack pine and Scots pine with a density of 0.3 units were formed. The yield of seeds from Jack pine cones was 1–2% higher than the normative values, and the mass of 1000 seeds was 50% higher. Jack pine seedlings grow according to I class of productivity on displaced sands, with an admixture of humus mass and remnants of genetic horizons of zonal soils at the root depth. In the rhizosphere of the stand, the roots of Jack pine seedlings occupied 78% of the mass of all roots that inhabited a metre-thick sand. Jack pine seedlings that fall under the canopy of Scots pine fall out of the plantations due to drying, which indicates their demand for light and appropriateness of growing Jack pine in solitary plantings or in mixed low-density plantations with Scots pine.

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:
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:
Tillage and plant residues influence soil attributes and, consequently, soil quality. Therefore, suitable management and maintaining the stability of soil structure is important. This study was performed to evaluate the effects of tillage systems on soil quality during a 4-year crop rotation (wheat, canola, wheat and tomato) at the Agricultural Research Center of Khorasan Razavi province (Iran) from 2011 to 2015. The study was conducted as a randomized complete block design in a factorial arrangement with 3 replications. For this purpose, conventional tillage (CT), minimum tillage (MT) and no-tillage (NT) systems together with three rates of plant residues (0, 1,500, and 3,000 kg ha-1) were applied annually after harvesting. Soil quality was determined by using the integrated quality index (IQI) and Nemoro quality index (NQI) based on total data set (TDS) and minimum data set (MDS). In total, 23 physical, chemical, and biological soil characteristics were considered as TDS and 7 out of these were selected as MDS for use in the principal component analysis (PCA). Soil quality in different tillage treatments was determined and the most appropriate indices and effective characteristics for soil quality assessment were selected. Correlation coefficients between IQITDS and IQIMDS (r = 0.69) and between NQITDS and NQIMDS (r = 0.76) showed that NQI was a better indicator for assessing soil quality. The NQITDS provided a more accurate and comprehensive assessment of soil quality. However, using MDS reduced the cost and time with proper precision. Soil quality in MT and NT treatments was more desirable than the CT system, and the addition of plant residues improved the soil quality. According to the results of NQITDS, IQITDS, and IQIMDS, soil quality in the NT system with 3,000 kg ha-1 of plant residues and the MT system with 1,500 and 3,000 kg ha-1 of plant residues were more favorable than other soil tillage treatments. Soil characteristics that decreased soil quality in the conventional tillage were soil structure, macro and micronutrients, while in conservation tillage it was micronutrients, especially Zn.

Opis:
Understanding the spatial variability of soil organic matter (SOM) is critical for studying and assessing soil fertility and quality. This knowledge is important for soil management, which results in high crop yields at a reduced cost of crop production and helps to protect the environment. The benefits of an accurate interpolation of SOM spatial distribution are well known at the agricultural, economic, and ecological levels. It has been conducted this study for comparing and analyze different spatial interpolation methods to evaluate the spatial distribution of SOM in Sidi Bennour District, which is a semi-arid area in the irrigated scheme of the Doukkala Plain, Morocco. For conding this study, it was collected 368 representative soil samples at a depth of 0–30 cm. A portable global positioning system was used to obtain the location coordinates of soil sampling sites. The SOM spatial distribution was performed using four interpolation methods: inverse distance weighted and local polynomial interpolation as deterministic methods, and ordinary kriging and empirical Bayesian kriging as geostatistical methods. High SOM levels were concentrated in vertisols, and low SOM levels were observed in immature soils. The average SOM value was 1.346%, with moderate to high variability (CV = 35.720%). A low SOM concentration indicates a continuous possibility of soil degradation in the future. Ordinary kriging yielded better results than the other interpolation methods (RMSE = 0.395) with a semivariogram fitted by an exponential model, followed by inverse distance weighted (RMSE = 0.397), empirical Bayesian kriging (RMSE = 0.400), and local polynomial interpolation (RMSE = 0.412). Soil genetics and the strong influence of human activity are the major sources of SOM spatial dependence, which is moderate to low. Low SOM content levels (< 1.15%) were present in the southwestern and eastern parts of the digital map. This situation calls for the implementation of specific soil recovery measures.

The article presents results of quality class determination and regulatory and monetary valuation of agricultural land in the steppe soils irrigation zone using the Karmanov’s methodology of soil and climatic quality class determination and author's methodology of ecological, agro-ameliorative and climatic soils quality class determination. Based on the results of spatial modeling, a series of maps was created and characteristics of ecological, agro-ameliorative and relief and climatic components of soils quality class were presented based on the example of the Kherson Region, Ukraine. According to the results soil and climatic quality class determination, it is established that the value of the class varies from 25 to 46 points; the regulatory and monetary value of agricultural land varies from USD 490 per 1 ha for dark chestnut and chestnut alkaline soils up to USD1,360 per ha for ordinary chernozem. According to the results of ecological, agro-ameliorative and climatic soils quality class determination, it is established that the value of the class varies from 6 to 59 points; the regulatory and monetary value of agricultural land varies from USD145 per 1 ha for degraded and highly saline chestnut soils up to USD2,060 per ha for irrigated southern chernozem. The suggested methodology of soil quality class calculation can have multiple purposes. It is intended to be used for different physiographic conditions of land use to develop adaptive soils protection measures at different territorial levels of agricultural production management with the overall objective of ensuring sustainable land use.

This paper aimed to evaluate the physical properties of the soils on the slope of the spoil heap of the coal mine in Bogdanka based on literature and the authors’ opinion. The field soil tests were carried out in the agricultural season of 2018 in the coal mine waste dump. The main purpose was to develop and apply the soil physical quality index. For the calculation of the SPQI used nine soil physical properties: texture, bulk density, MWD, AWC, K, POR, PAW, S, StI. The paper used a system for assessing the physical parameters of soil within the range from 0 to 4. On the basis of the research, it was found that the best parameters of soil quality occurred in the surface horizons and increased with depth. The SPQI value calculated for the 0–60 cm Technosol layer was 0.51, which indicates good soil parameters.

Any type of material that increases soil yield, both qualitatively and quantitatively, to strengthen the soil and increase its fertility is called fertilizer. The current study examines the production of a new effective fertilizer. Results presented involve effects of new bioorganic-mineral compositions obtained from the combination of vermicompost and sulphur-containing waste from sulphuric acid production on the yield and quality of tubers (beets, carrots). An increase in the yield of tubers has been found to be 1.13–1.25 times when the bioorganic-mineral composition (~20 Mg∙ha–1) is introduced into the sierozem (serozem) soil. The best results are obtained with mass ratios in the range 30–45 and 55–70 for vermicompost and sulphur-perlite-containing waste, respectively. The effectiveness of the mixture of vermicompost and sulphur-containing waste is explained by the increased synergistic interaction of these components. The proposed composition has high structure-forming, water-retaining, nutritional and biologically active properties.

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 aim of the experiment, conducted in 2005-2011, was to make an assessment of the influence of spring spring barley sowing technology (pure and with companion crops) in crop rotation sequences with 25, 50 and 75% shares of spring spring barley on chemical changes in the 0-20 cm soil horizon. In 2011, spring spring barley (pure sowing) on a stand where spring barley preceded spring barley in a crop rotation system with a 50% spring barley share was found to cause a decline in soil pH and a rise in the soil content of organic carbon (C org.) in comparison with the treatments where companion crops were undersown. Spring barley with the companion crop of Italian ryegrass on a spring barley after spring barley stand raised the pool of C org. in soil relative to the period before the experiment, but the opposite effect was observed when spring barley was undersown with red clover on a stand after potato. In the pure stand, after seven years of the experiment, the highest increase in the soil phosphorus (P) content was noted under the spring barley field following spring wheat, whereas on the plots with the Italian ryegrass companion crop in a sequence of spring barley after spring barley repeated twice the soil was richer in P than prior to the experiment. Once the experiment was terminated in 2011, more potassium (K) was determined in soil under pure spring barley than under spring barley with companion crops. Spring barley with Italian ryegress as a companion crop raised the content of K in soil, but a reverse situation was observed on plots with red clover undersown on a stand of spring barley after potato in comparison with the crop rotation sequences of spring barley after spring wheat and after spring barley. In the case of the soli pH and phosphorus, a positive correlation was noted in the sequence of spring barley undersown with red clover on a stand after spring barley in the crop rotation system with a 75% of spring barley.

W artykule przedstawiono systemy monitoringu środowiska przyrodniczego o zasięgu ogólnokrajowym, związane ze środowiskiem gruntowym. Pierwszy to monitoring chemizmu gleb ornych, ujawniający jakość gleb rolniczych w Polsce. Monitorowane jest 216 punktów. Problem stanowi głównie zakwaszenie gleb oraz niedobór przyswajalnego fosforu. Drugi to monitoring suszy rolniczej. Jest oparty na wyznaczaniu klimatycznego bilansu wodnego w powiązaniu ze zdolnościami retencyjnymi gleb. Stwierdzenie suszy uprawnia do uzyskania państwowej pomocy finansowej. Trzeci to monitoring osuwisk, który dotyczy głównie obszaru Karpat Polskich. Wyznaczane są tereny zagrożone ruchami gruntu, a w obrębie osuwisk analizowane są przemieszczenia powierzchniowe (pomiary GPS) i wgłębne (pomiary inklinometryczne). Opisano zakres każdego monitoringu, a także podano liczne informacje metodyczne. Zwrócono uwagę na praktyczne aspekty działań monitoringowych. Wyniki każdego monitoringu są w różnym zakresie dostępne do wiadomości publicznej, co umożliwia ich dyskutowanie.
The article presents nationwide environmental monitoring systems related to the ground environment. The first system is the monitoring of chemical properties of arable soil, aiming to estimate the quality of agricultural soils in Poland. Totally 216 points are being monitored. The problem is mainly soil acidification and a deficiency of available phosphorus. The second one is monitoring of agricultural drought. It is based on the determination of the climate water balance in connection with soil retention capacity. When a drought is confirmed it entitles to receive state financial assistance. The third system is the landslides monitoring, which mainly concerns the area of the Polish Carpathians. The areas endangered by ground movements are indicated, and within landslides surface of ground displacements (GPS measurements) and deep movements (inclinometric measurements ) are analyzed. The scope of each monitoring was reviewed, as well as numerous methodological information was given. The attention was paid to practical aspects of the monitoring activities. The results of each monitoring are available to be public message in varying degrees, which makes it possible to discuss them.

Opis:
Improving water productivity (WP) through deficit irrigation is crucial in water-scarce areas. To practice deficit irrigation, the optimum level of water deficit that maximizes WP must be investigated. In this study, a field experiment was conducted to examine WP of the three treatments at available soil water depletion percentage (Pi) of 25% (reference), 45% and 65% using a drip irrigation system. Treatments were arranged in a randomized complete block design. The water deficit was allowed throughout the growth stages after transplanting except for the first 15 days of equal amounts of irrigations during the initial growth stage and 20 days enough spring season rainfall during bulb enlargement periods. Physical WP in terms of water use efficiency (WUEf) for treatments T1, T2, and T3 was 9.44 kg∙m–3, 11 kg∙m–3 and 10.6 kg∙m–3 for marketable yields. The WUEf and economic water productivity were significantly improved by T2 and T3. The WUEf difference between T2 and T3 was insignificant. However, T2 can be selected as an optimal irrigation level. Hence, deficit irrigation scheduling is an important approach for maximizing WP in areas where water is the main constraint for crop production. The planting dates should be scheduled such that the peak water requirement periods coincide with the rainy system.
