This study aims to evaluate the effects of foliar fertilization (FF) on the yield and quality of sunflower seeds. Foliar fertilization (FF) applied to sunflower crops can have significant impacts on seed yield and quality, influencing their chemical composition and nutritional values. Unlike soil fertilization, which delivers nutrients through the root system, foliar fertilization supplies nutrients directly to the leaves, ensuring a rapid and efficient absorption of essential elements during critical growth stage...

This study investigates the effects of foliar fertilization (FF) on the yield and quality of corn grains, utilizing Principal Component Analysis (PCA) to optimize foliar treatment applications. The PCA approach enabled the identification of the most effective FF formulation for enhancing grain production and quality. The experiments were conducted in 2022 and 2023 at the university's experimental field, evaluating seven treatment variants, each with distinct chemical compositions labelled from V1 to V7, along with...

Between September 13th and 16th, 2024, heavy rainfall led to widespread flooding across the municipalities in the Senica district, as well as significant soil erosion on intensively farmed arable land. According to data from the Slovak Hydrometeorological Institute (SHMU), the Senica district received a total of 230 millimeters of precipitation during this period. In the village of Smolinske, located in the lowlands of Zahorie in western Slovakia, experienced substantial flooding of agricultural areas, leading to ...

Agate-like soil cover structures (ASCS) of leached chernozems are common in some regions of Russia with a total area of 425 242 km2 (the republics of Tatarstan and Bashkortostan, Orenburg, Samara, and Ulyanovsk regions). The term -agate-like structures- was proposed due to the fact that on remote sensing data they resemble a section of the Timan agate. The structures are formed on loamy and clayey Quaternary sediments with a thickness of 0.5-5 m, overlying Permian sediments (bedrock). It is possible to identify th...

The research is aimed at identifying the conditions for the formation of the ecological agriculture concept aimed at creating a sustainable, environmentally friendly and efficient agricultural production system. The main idea is to use natural processes and resources to ensure a harvest while maintaining the environmental balance. Ecological farming can be an important step towards sustainable agriculture and environmental sustainability, but it requires a balance between positive and challenging aspects, as well ...

The cultivation of American cranberries (Vaccinium macrocarpon Aiton) with organic fertilizers is becoming more common in the world. With 180 ha of producing plantings and 376 tonnes of yearly production, Latvia is one of the largest cranberry producers in the world. The lack of knowledge on fertilization management can be an obstacle to a successful transition to organic farming. The objective of this study was to test the effect of organic fertilizer of animal origin on cranberry mineral nutrition status, plant ...

The soils from the central part of Sredna Gora Mountain in Bulgaria were studied aiming to establish the occurrence of contemporal soil forming processes occured in the forest ecosystem. Soils were analyzed to determine the carbon content, the soil organic matter composition and the total soil acidity. The precise soil classification based on the detail morphological diagnostic was carried out. The ecological conditions in forest ecosystem determine the mode of humic substances in the studies soils. Soils are char...

Geochemistry, a young earth science discipline, has evolved with chemical analysis techniques and is now integrated with environmental issues. Industrial development has increased the input of toxic elements into soil, water and air, potentially affecting the food chain. Geochemical tools investigate these sources and assess the risk of contamination. The combination of background enrichment indices and contamination indices provides a robust framework for understanding soil contamination. This dual approach enabl...

To enable effective operational decisions and combat mission execution on the battlefield during war, access to reliable, accurate, and timely data is essential. We propose utilizing Geographic Information Systems (GIS) to analyze extensive datasets, as modern military operations rely on accurate spatial terrain mapping for command, control, communication, and coordination. This study introduces a terrain analysis approach tailored to military vehicle movement, focusing on assessing ground resilience to vehicle tr...

The presented paper focuses the issue of finding new sources of phosphorus fertilizers to be used in conventional agriculture. Various types of pellets for heating purposes were tested. Based on the determination of phosphorus (P) content in ash obtained from the combustion of pellets produced from plant waste generated during the production of seed materials, it was found out that getting P from this ash is more effective than getting P from the ash of wooden pellets that are commonly used as fuel in households. ...

Micromorphological features of salt-affected soils in the Cis-Baikal and Trans-Baikal regions (south of East Siberia, Russia) are considered. When studying morphogenesis of these soils, pedofeatures of soluble salts and gypsum serve as indicators of modern and former stages of soil formation. Comparative-geographical, micromorphological, and chemical methods have been applied to study soil salinization. Chemical analyses attest to the presence of gypsum and soluble salts in solonchaks of both regions. However, the...

New methods for assessing soil cover heterogeneity, based on the analysis of extensive satellite data using neural network filtering technologies, were implemented to evaluate the territory of northern Kazakhstan. A comparative analysis of the quality of soil cover structure (SCS) determination, using remote sensing data, was conducted using two different methods. The first method is indirect and involves determining the SCS by analyzing and aggregating multitemporal vegetation indices (MVI). The second method is ...

Phytoremediation technology is environmentally friendly and inexpensive to clean soils of harmful toxins. The study aims to introduce phytoremediation of arsenic in the Racha-Lechkhumi and Kvemo Svaneti regions to restore soil fertility. For this study, three plants, Amaranthus gangeticus, Chenopodium album and Helianthus annuus, were selected for the accumulation and translocation of Arsenic from the contaminated soil. The seeds of selected plants were treated with the bioactivator Biorag to increase the plant's ...

Orphaned or abandoned sulphide tailing disposal sites pose significant environmental hazards, including eolian dispersion, water erosion, acid mine drainage, and heavy metal mobility. Phytostabilization, an eco-friendly strategy, entails the use of alkaline amendments alongside non-native plant species capable of thriving in environments with high concentrations of heavy metals. A greenhouse experiment was conducted to assess the effect of a commercial cement which contained 46.3% sand, applied alone or combined w...

Potential environmental impacts of growing maize as monoculture lead to efforts focused on finding other potentially suitable crops or their combinations that could replace the pure maize cultures. The most frequent and most effective combination is a mixed crop of maize and legumes. The presented paper deals with the issue of the quality of post-harvest residues when growing maize in the system of mixed cropping. In the field experiment, yield and quality of post-harvest residues were studied during the growing s...

The health, richness, and variety of microbial life in soil represent basic indicators for the evaluation and surveillance of forest ecosystem vitality. The vital role these microorganisms occupy in forest ecosystems underscores the necessity to in-depth assess and monitor their populations within soil habitats. Aiming to deepen our comprehension of microbial communities across different soils and soils horizons, we conducted an investigation of 22 soil profiles situated within the territory of Vitosha Nature Park...
