Plant nutrition in urban environment

Opterećenje: 30+0+0

Sadržaj predmeta: 1. Historical development of plant nutrition as a scientific discipline, definition and classification and division of biogenic elements and plant nutrients. Soil as a source of plant nutrients; chemical composition of the soil, colloid properties of the soil, pH reaction of the soil, buffer capacity of the soil, forms of nutrients in the soil, dynamics of nutrients in the soil. 2. Potential, uptake and transfer of nutrients through the plant; potential and availability of plant nutrients, receiving nutrients through roots, uptake of nutrients by leaves, transfer of nutrients between cells. 3. Factors that influence the adoption of nutrients in specific conditions of the urban environment; plant species and genotype, mycorrhiza, soil fertility, soil moisture, soil salinity, root metabolism. 4. Supply of plants with biogenic elements; antagonism and synergism of biogenic elements, retranslocation of mineral nutrients within the plant. Loss of nutrients from the plant organism and general symptoms of deficiency and excess of elements of plant nutrition. 5. Macroelements and Nitrogen; forms of nitrogen in the soil and their availability to the plant, nitrate reduction in the plant, the role of nitrogen in plant metabolism, signs of insufficient nitrogen nutrition. 6. Phosphorus; forms of phosphorus in the soil and their accessibility to plants, the role of phosphorus in plant metabolism, signs of insufficient phosphorus nutrition. 7. Sulfur and potassium; forms in the soil and their accessibility to the plant, their role in the plant and symptoms of their deficiency on the plant. 8. Calcium and magnesium; forms in the soil and their accessibility to the plant, their role in the plant and symptoms of their deficiency on the plant. 9. Microelements and iron; forms in the soil and availability of iron to the plant, its role in the plant and symptoms of its deficiency on the plant. 10. Manganese and boron; forms in the soil and their accessibility to the plant, their role in the plant and symptoms of their deficiency on the plant. 11. Zinc, copper, molybdenum, chlorine and nickel; forms in the soil and their accessibility to the plant, their role in the plant and symptoms of their deficiency on the plant. 12. Interactive influence of stress factors in the urban environment and suboptimal nutrition with mineral nutrients on the physiological constitution and vegetative growth of plants. 13. The problem of taking samples and analysis with the aim of determining the concentration of mineral nutrients in the soil and in the plant. 14. Fertilizers in general, their division and chemical analysis. 15. The influence of different doses and formulations of mineral fertilizers on the physiological constitution and vegetative growth of plants.
