Trace their mark on leaf growth in November. In this category are: Iron (Faith), Copper (With), Manganul (Mn), Zinc (Zn), Molybdenum (Mo) and Boron (B).
Iron: Younger leaves when suffering from iron chlorosis is missing or assimilated by the plant in very small quantities. Following, the growth of the flower Gets a white color. Because excess iron, violets rarely suffer. This is possible only if the mix of land containing iron sulphate. In this case, plant dies immediately after planting because of rapid proliferation and necrotic spots appear on the leaves.
Copper: Copper deficiency favors the appearance of chlorosis on the youngest leaves. In the second stage of plant growth point turns a brownish, but does not rot.
Manganul: Manganese deficiency favors the appearance of chlorosis on the youngest leaves, necrosis of the older leaves stains on. In the mixture of Earth with a high acidity can alter manganese Valence from 4 to 2, pantrunda which allows it to quickly settle in plant tissues and its. Plant dehydrates, May be unable to absorb water from the soil. Violets lose turgor with symptoms of Phytophthora infestation.
Excess manganese in soil is moderately negative effect on stems and leaves. Stems become brittle, bumps appear on the leaves and stumps.
Zinc: Following zinc deficiency chlorosis plant can suffer from atypical. Yellow spots on leaves rather highlighted and jagged edges. In the second stage, leaves its edges curve and remain in this position without loss of turgor. Excess zinc afesteaza especially species of violets with variegated leaves. Specific spots on the leaves of these species during disappear.
Molybdenum and Boron: Molybdenum exception. Molybdenum deficiency can take a toll on older leaves: a halo of yellow on the leaves followed by burns. Boron deficiency leads to death of growing point of the plant. It dries and while old leaves are affected by chlorosis. Excess boron is disappearing spots on leaves violets with variegated leaves. It burns may occur on the edges of leaves.
But! In everyday life we meet excess or deficiency of one element. This phenomenon is found only in laboratory experiments. In practice we encounter the lack of an element in combination with other. To determine the exact diagnosis requires a personal approach and checking water quality that are watered flowers.
