A subsoil plus surface drip irrigation system is proposed, which combines the advantages of the two systems operating separately and at the same time eliminates their disadvantages. Seven main advantages of the developed system are systematized, factors and parameters that determine the quality of the system are defined.

  • Evaluation of vegetation indices in organic vineyards using plant-o-meter sensor measurements

    pg(s) 60-62

    Increased environmental concerns and the growing demand for sustainable agricultural practices are encouraging the development of more sustainable agricultural management systems. In the field of viticulture, increasing attention is being paid to the use of alternative organic plant protection products, which can reduce dependence on synthetic pesticides while maintaining grape yield and quality. At the same time, high-precision vineyard technologies enable more detailed monitoring of vineyard conditions and spatial variability. Vegetation indices derived from spectral measurements provide valuable information on plant vigor, physiological status, and potential stress. Consequently, the combination of environmentally friendly plant protection methods with modern monitoring tools represents an important step towards sustainable vineyard management. The aim of this study was to evaluate the effects of organic plant protection products on grapevine vigor using NDVI and NDRE vegetation indices. The study was conducted in a vineyard with two grape varieties, representing table grapes and wine grapes. Vegetation monitoring was carried out using a Plant-O-Meter sensor, enabling nondestructive spectral measurements of the grapevine canopy. Measurements were carried out before the application of organic plant protection products (control measurements) and twice after treatment in July, when the plants were fully developed. Spectral data were used to calculate two widely applied vegetation indices, NDVI and NDRE, in order to evaluate changes in plant vigor and physiological status. The results showed variability in vegetation indices across cultivars and observation periods. In table grape cultivars, NDVI values ranged from 0.58 to 0.60, while NDRE values ranged from 0.023 to 0.11. In wine grape cultivars, NDVI values remained stable at 0.73, whereas NDRE values ranged from 0.10 to 0.12. Correlation analysis revealed significant relationships between vegetation indices and production parameters. In table grape cultivars, significant correlations with yield were observed during the first measurement for NDRE (r= 0.99) and NDVI (r= 0.91). In wine grape cultivars, significant correlations were found during the third measurement between NDRE and total acidity (r= 0.898), as well as between NDRE and sugar content (r= 0.926). Two-way ANOVA indicated that cultivar had a significant effect on NDVI values, while NDRE was significantly influenced by cultivar, observation period, and their interaction (p= 0.001). The results demonstrate that NDVI and NDRE can be used as reliable indicators for monitoring vineyard canopy vigor and assessing the impact of organic plant protection products, highlighting their potential as valuable tools for supporting sustainable vineyard management.

  • Soil characterization by capillary test

    pg(s) 55-59

    This article deals with the characterization of soil using the capillary effect. The interactions between water molecules and those of a soil sample cause a liquid to flow upwards. The climbing height and rate of rise are strongly dependent on the geometric shape of the pore system of the soil sample hence these parameters can be used for soil characterization. The paper shows that capillary action is primarily responsible for cohesion in the soil, and it is therefore physically quite reasonable to use related properties for soil characterization in agricultural machinery applications. This paper presents a method to derive dimensionless key figures allowing the experiment-independent characterization of the soil sample. The aim is the computer-simulation of soil behavior for applications in agricultural technology. Calibration of Discrete Element Method (DEM) models involves matching virtual particle parameters (friction, stiffness, restitution) of the simulation model to the real soil behavior like cohesion and abrasion. Properties of the developed agricultural machineries, such as traction requirements, power consumption and wear behavior, can thus be predicted very soon in the product development process. The characterization enables an assignment of a given soil to an established set of simulation parameters. Two soil samples examined can be easily and reliably distinguished from each other using the method presented.

  • Productivity of irrigation water and irrigation effect of raspberries grown under optimum irrigation conditions and water deficit

    pg(s) 27-29

    This paper deals with the productivity of irrigation water and the effect of irrigation on raspberries in the Chelopechene experimental field. We examined different regimes, keeping from full satisfaction of daily water needs of crop to irrigation with reduced by 20 and 40% irrigation norms and variant without irrigation
    Moisture optimization in the active soil layer contributes to a significant increase and stabilization of yields, which for the test conditions range from 835 to 1074 kg / dka, with additional yields ranging from 404 to 627, kg / dka or from 47 to 59% on average for the study period. Established productivity irrigation rate is highest in the variants irrigated with a 40% reduction in the optimum norm and varies in units from 13.0 kg. ha -1.mm-1 to 24.0 kg.ha – 1.mm-1, and it is low in the irrigation variants with 100% irrigation rate, with the highest values reaching in the dry year 2000.

  • Energy consumption of primary tillage operations in conventional and no-till farming systems – a review

    pg(s) 22-26

    This article reviews domestic and international literature on the energy consumption of primary tillage operations in four farming systems: conventional (plough-based) tillage, simplified tillage, strip-till and no-till farming. The energy inputs of individual agrotechnical operations were analysed, with particular emphasis on fuel consumption, cumulative energy, CO₂ emissions and the impact on the physical and biological properties of the soil. The results of the review indicate that switching from ploughing to no-till farming reduces fuel consumption by 60–80%, energy inputs by 55–75%, and greenhouse gas emissions by 65–80%. At the same time, no-till systems promote the accumulation of organic matter in the topsoil, improve the stability of soil aggregates and protect against erosion. The limitations of no-till farming under Polish conditions were also discussed, including the risk of seed embedding in heavy soils, problems with weed control, increased reliance on herbicides, and economic and psychological barriers. An economic analysis of cultivation costs in individual systems was carried out for a model farm with an area of 100 ha.

  • Synthesis of Carbon Adsorbents with Potential Application for Water Purification for Environmental Protection

    pg(s) 123-124

    Carbon adsorbents were synthesized from waste biomass through controlled carbonization and activation processes, aiming to develop sustainable materials for environmental applications. The produced carbons exhibited a well-developed porous structure and high specific surface area, as confirmed by textural characterization. These structural features contributed to enhanced adsorption capacities toward various water pollutants, including dyes, heavy metals, and organic contaminants. The adsorption mechanisms were mainly governed by surface interactions and pore diffusion, indicating strong affinity between the adsorbents and the target molecules. The use of renewable biomass as a precursor not only reduces production costs but also supports waste valorization and circular economy principles. Overall, the synthesized carbon materials demonstrate significant potential as efficient, low-cost, and environmentally friendly adsorbents for water purification and protection of aquatic ecosystems.

  • Selective polymer materials for iron speciation in surface waters

    pg(s) 120-123

    Iron in surface waters occurs in a variety of physical and chemical forms, each exhibiting distinct reactivity and environmental behaviour. To advance the understanding of how individual biogeochemical processes interact and how aquatic ecosystems respond to shifts in iron speciation, it is essential to establish reliable analytical approaches. In this context, the development of a procedure capable of determining the most reactive and kinetically labile fractions of Fe(II) and Fe(III) represents a timely and significant challenge in contemporary environmental analytical chemistry.

  • Soil pollution: pollutants, causes and effects

    pg(s) 115-119

    Soil is a complex heterogeneous system composed of solid, liquid and gaseous matrix, which is a key factor for terrestrial ecosystems. As an open system, it is a source or sink of many substances, including pollutants. Pollutants in soils can be of natural or anthropogenic origin, which are generally divided into two main groups: organic and inorganic pollutants. The report is prepared on the basis of scientific literature and is entirely aimed at clarifying the sources, impact and effects of persistent organic compounds. For this purpose, 32 scientific articles available in ResearchGate, Scholar and ScienceDirect were studied. Attention is focused on them, as they are considered a global environmental problem due to their persistence, potential for bioaccumulation, toxicity, carcinogenic and mutagenic potential.

  • Prototype of a SMFC-based biosensor for real-time monitoring of heavy metals polluted water

    pg(s) 108-111

    Timely detection and treatment of water pollution is of utmost importance for preventing serious environmental pollution and toxicity to living organisms. Traditional monitoring methods require time for sampling and analysis, and those that provide real-time monitoring are expensive and have limited application. The development of a low-cost sensor for real-time water monitoring will enable wider application and quality management of more water bodies. Guided by this, we constructed and tested a prototype of a biosensor based on a sediment microbial fuel cell. The sensor showed high efficiency and sensitivity to the most common heavy metals pollutants from industrial, agricultural and domestic wastewater. The sensor is designed for both portable and desktop applications, as well as for integration into the technological schemes of enterprises for continuous monitoring.

  • Alleviating negative impacts of drought on water resources, agriculture and environment in Konya closed basin

    pg(s) 104-107

    Water scarcity is a global phenomenon and is described as a marked decrease in precipitation, relative to the historical average, over a period of time. The negative consequences of drought are far worse than the positive outcomes. The Konya Closed Basin (KCB), characterized by a semi-arid climate zone, has been among the worst-affected regions in the last several decades. There have been reports of surface water bodies (e.g., Beyşehir Lake, Altınapa Dam) in the KCB declining in water levels. There has been a sustainable supply of water over the last two years of the drought period, and in the case of Beyşehir Lake and Altınapa Dam, which are the two largest surface water storage bodies on the Konya Plain, the water levels have fallen below usable levels, causing larger implications for the agricultural settings and aquatic environment. Therefore, increasing reliance on groundwater supplies has steadily worsened aquifer depletion and general declines in well yields across the KCB. In particular, excessive groundwater use has led to the formation of many sinkholes across the KCB, with a higher incidence of occurrence in the Konya-Karapınar district, termed the desert of Türkiye. After experiencing recurrent and severe drought conditions, agricultural farmers growing high water-consuming crops like alfalfa, maize, and sugar beet on their farming systems often showed higher economic returns on these crops, so that these farmers selected to grow these crops rather than consider the issue of water availability. Thus, financial mechanisms need to be established to incentivize the production of cereals with low water demand to relieve drought-related pressures. Moreover, it is also important for soil protection to convert land to drought-resistant crops, shrubs, and trees. Lastly, large-scale application of pressurized irrigation techniques, particularly using sprinklers and drip irrigation, is necessary to improve water use efficiency under constrained conditions.
