    Detection of heavy metals in soil to determine phosphorus and potassium levels
    (CEP USM, 2024-10-07) Holomb, Lyudmila; Vakerych, Mykhailo; Hasynets, Yaroslava; Schwartau, Victor
    The presence of heavy metals in the soil can significantly affect the formation of available levels of the main macronutrients, in particular, phosphorus and potassium. This dependence is used in modern technologies for determining the content of phosphorus and potassium in soils, for example, based on the rapid determination of gamma irradiation of K40, U238, Th232, Cs237. These interactions are influenced by several factors, including soil properties, heavy metal concentrations, and plant species. Understanding these interactions is essential for effective soil management, environmental protection, and increasing the productivity of agrophytocenoses. The use of these technologies enables the development of highly sensitive methods for rapid assessment of phosphorus and potassium in soils and for regular soil monitoring to mitigate the negative effects of heavy metals in agrophytocenoses and to ensure balanced nutrient availability for plants.

    INFLUENȚA POTENȚIALULUI DE FERTILITATE A SOLULUI ASUPRA INDICILOR DE PRODUCȚIE LA FLOAREA SOARELUI CULTIVATĂ ÎN RAIONUL CAHUL, REPUBLICA MOLDOVA
    (CEP USM, 2023) Paladi, I.
    Sunflower is a plant widely used in the food industry and human food. In the diet of the peoples of Eastern Europe, sunflower oil is the most important source of calories as much as bread. And sunflower seeds are the second product by volume exported from the Republic of Moldova. Due to drought resistance and unpretentiousness to agrophytotechnical measures and a good marketing price it is one of the most profitable crops grown in our country. However, soils do not have the same production potential everywhere and this must be taken into account when developing cultivation technologies as well as the choice of hybrids.
