A global bibliographic review of soil variability trends on arable land: An impetus to sustainable land management
27-39Views:153Crop production is significantly affected by soil properties under the influence of climate, management practices, and geographical location. Soil variability affects the development, quality, biochemical reactions, and heterogeneity of soil. The most recent research has focused on soil variability monitoring, highlighting the importance of soil testing. This review aimed at identifying global research trends and assessing soil testing in monitoring variability on arable land, based on the bibliographic method. Literature search in Scopus Database (2020-2023) yielded 8,898 documents, refined to 815 articles. VOSviewer 1.6.20 Software was used for analysing exported data. The results revealed a growing emphasis on monitoring soil variability, with key countries including India, United States of America (USA), China, Australia, Canada, United Kingdom, and Brazil. Funding mainly came from Asia, North America, and Europe. Common monitoring approaches included soil tests and remote sensing, focusing on organic carbon, nitrogen, phosphorus, potassium, microorganisms, and soil moisture. However, digital illiteracy and high costs were major hindrances to using remote sensing and modern soil testing tools. The study suggests that whereas soil variability monitoring is essential for sustainable land management, development of affordable soil testing equipment and improved digital education are needed for its enhanced adoption.

Stress Response of four Common Carp (Cyprinus carpio L.) Varieties with Different Genetic Background
26-29Views:167Four different carp varieties were tested for stress reaction, with the help of 10 °C cooling and 100 g/l crowding. The selected varieties represented a broad genetic spectrum of carp species. The stress was monitored by measuring plasma cortisol, glucose and lysozim levels. In each test different varieties showed significantly different reaction to stress. This means that they differ in the trait of general resistance. Thus, this trait can be used in selection programmes and the acquired information helps to understand fish-environment interaction and specific resistance. These traits should be used in selection to improve the breeding of new more tolerant species for intensive farming or for organic production.

Examination of the possible role of biofertilizers and wood ash in the nutrient supply of plants
87-95Views:214Some physiological effects of bacteria containing fertilizer and some wood ash were examined in the experiments. The minimization of the use of chemicals in agriculture has been an ongoing challenge. One option lies in the intenzification of soil life. The release of organic matters by the roots and bacteria play a significant role in the uptake of minerals. The main problem to usilize wood ash in agriculture is its heavy metal contents. The solubility of heavy metals is very low, therefore there is no risk to use the wood ash in the agriculture and in the horticulture according to our experiments. The wood ash and biofertilizer contains several micronutrients in an optimum composition for forestry and agricultural plants.

Stripe rust reaction and yield response of winter cereals in bio - versus conventional farming
47-50Views:232In 2014, was an extremely early and heavy yellow rust (Puccinia striiformis var. striiformis) epidemic in Hungary. Significant differences were among locations, years and genotypes in the severity of infection. Ratio of the resistant and moderately resistant genotypes was higher under bio environment. The yellow rust epidemic caused significant yield decreasing in the tested winter cereals.
