REQUIREMENT OF PLANTS FOR MANGANESE.
Depending on specific features, conditions of growth and an agrotechnics, the manganese content in tissues of plants fluctuates: 5-500 mg/kg of dry mass, on a thicket of 25-250 mg/kg. This element concentrates in small quantities in reproductive organs and in considerable quantities in vegetative organs, and the main thing in leaves. Greater the manganese content contains in leaves of bean cultures and a beet, and the low content of manganese in leaves of grain crops.
The set of the parties of a metabolism is connected with manganese in a vegetative organism, it accepts active participation in regulation of reaction of oxidation and a reduction in processes of a nitric and carbon exchange, in breath of cages, photosynthesis etc. As a result of multilateral participation in a metabolism of a plant manganese influences quality indicators of crops: the sugar content in root crops of a sugar beet and fruits of a strawberry, starch in tubers of a potato, fiber in grain of grain crops, on vitamin C in fruits, berries and vegetable cultures.
REQUIREMENT OF SEPARATE CULTURES FOR MANGANESE.
On responsiveness degree to manganese crops can be divided into four groups:
-
Bean cultures, barley, corn grasses;
-
Flax, clap, spring wheat;
-
Hemp, sugar beet, potato;
-
Winter wheat.
From fruit-berry cultures the strawberry, a pear and a peach are more sensitive to a manganese lack, than an apple-tree and a cherry, and from vegetable cultures - a beet, a radish, salad, a bean, peas, heads and a cauliflower.
At the majority of crops the requirement for manganese increases in a flowering time and formation of fruits, and at edible roots - during the period formation of roots and tubers. Some cultures have exceptions - a clap the requirement for manganese for a growth incipient period, for example, feels.
For the majority of crops critical concentration of manganese in leaves about 20-25 mg/kg of dry mass, and the toxic content for barley above 200 mg/kg, for a soya above 250 mg/kg of dry mass, for corn above 300 mg/kg, for tomatoes and fruit-trees above 600 mg/kg, for a potato above 800 mg/kg and for a red beet above 1000 mg/kg of dry mass.
SOIL AS THE SOURCE OF MANGANESE FOR PLANTS.
Manganese total in superficial horizon of the Bulgarian soils, in borders of 0,018-0,332%. Basically it is connected with mineral and a chemical compound forming bedrock rocks.
In soil manganese meets in various connections. At oxidative-reducing conditions, characteristic for soils, manganese can be in the form bivalent, trivalent and tetravalent connection: water-soluble salts, manganese in organic connections, difficultly soluble manganese salts etc. Accessible to plants, manganese is in soil in the form of water-soluble salts (nitrate, chloride, sulphate and salts of organic acids), exchange ions and easily reducing oxides bivalent and trivalent manganese. In the plant nature use first of all water-soluble and exchange manganese in the form of bivalent ions. At an easy approach of air manganese quickly is oxidised and passes in poorly soluble tetravalent connections. Therefore water-soluble connections of manganese are in soil in insignificant quantity or are absent.
Organic connections of manganese meet in meadow soils and bogs are more often. Mobility of manganese is caused oxidative-reducing processes in soil, the content of humus, mechanical structure of soil etc., however the great value is rendered by soil reaction. Sour reaction raises solubility of manganese, and alkaline reaction reduces solubility of manganese. At soil reaction рН 8 all manganese passes in insoluble connections and plants start to test manganese deficiency.
SOILS WITH THE LOW CONTENT OF MANGANESE.
Soils with the low content of manganese:
-
Calcareous chernozems;
-
Carbonate-loamy soils;
-
Some typical chernozems;
-
Light-brown soils;
-
The salted soils.
At cultivation of crops on soils with the low content of manganese the foliar top dressing the Natural microfertilizer «MANGANESE HUMATE» in a dose of 0,5-1,0 l/hectares is required.
The foliar top dressing a microfertilizer «MANGANESE HUMATE» is obligatory at cultivation of crops sensitive to manganese: a beet, a radish, salad, a bean, peas, heads and a cauliflower, bean cultures, barley, corn grasses, flax, a clap, spring wheat, and also a pear and a peach.VISUAL SIGNS IN PLANTS AND ILLNESS CAUSED BY DEFICIENCY OF MANGANESE.
In comparison with deficiency of iron and zinc symptoms of manganese deficiency at various cultures have poorly expressed general character. On young and middle age leaves (on all cultures suffering from manganese deficiency) it is shown a chlorophyll, cages are braided and die off, deficiency of manganese leads to sheet twisting to the top area of sheet and occurrence brown or black-coffee necrosis. This disease on separate cultures is shown as specific and is known under various names: a grey spot, a wet or marsh spot, manganese a chlorosis etc.
At deficiency of manganese, with a grey spot in the first days of growth oats, barley, wheat, a rye and corn falls ill. On leaves between veins there are separate light yellow stains in the form of points or slanting faltering lines, which become after a while grey (at oats) or light (at a rye). At strong manganese deficiency of a stain merge on length of sheet in the form of lines, gradually dry up, become coffee and form plots with a dead tissue. At oats and a rye these lines pass on the sheet middle, and at wheat – is closer to a sheet edge. At early and strong disease of a plant can be lost, and at weak defeat of a plant blossom, but form few seeds.
The yellow spot is shown at a sugar and red beet, turnip, a potato, cabbage, salad, sunflower, a soya, a bean and at other cultures. At this disease leaves turn yellow, edges of leaves rise to top, leaves dry up and fall down. Soya leaves become covered is light-green stains which diseases with development become yellow. In many cases there are small coffee stains which gradually increase, merge and form plots with a dead tissue.
At strong deficiency of manganese peas suffer from a wet or marsh spot. The plant outwardly looks completely healthy, but on seeds there are coffee or black stains.
At deficiency of manganese fruit-berry cultures are amazed chlorosis. Manganese a chlorosis damages a pear, an apple-tree, a peach, citrus fruit crops, a currant, a raspberry, a strawberry and other cultures. It is established that separate fruit-berry cultures differ on the reaction to deficiency of manganese. For example a pear and wild strawberry more sensitive to deficiency of manganese, than an apple-tree and a cherry. At the majority fruit-berry cultures of a chlorosis it is shown between veins, in the beginning from a sheet edge and extends to the sheet middle. Leaves from above start to wither and early fall down. At strong deficiency of manganese clones of trees perish, and on fruits of citrus and plums appear outgrowths.
It is required to distinguish to a chlorosis caused by deficiency of manganese from iron chlorosis. At a peach, a cherry, plum, an apple-tree and a raspberry signs of iron deficiency are shown on young leaves, and at manganese deficiency – on old. Besides, in early phases of disease manganese chlorosis, on leaves near an average nerve much more green tissues, rather than at iron a chlorosis.
The lack and deficiency of manganese causes following important diseases of plants:
-
Manganese a chlorosis;
-
Manganese a necrosis;
-
Grey spot of grain crops;
-
Yellow spot of vegetable cultures;
-
Wet or marsh spot of bean cultures.
For protection and treatment of the diseases set forth above it is necessary to process crops some times a solution of the Natural microfertilizer «MANGANESE HUMATE». A sugar beet and a potato process twice during formation of a root crop and tubers, and a clap in a budding (before flowering). Fruit-trees and vineyards process 2-3 times during vegetation with an interval in 1-2 weeks.
Amazed manganese chlorosis trees are required to be processed in a dormant period (before melting of kidneys) a strong solution of the Natural microfertilizer «MANGANESE HUMATE».
Necrosis on inside layers of a bark at an apple-tree it is shown from surplus on mobile manganese in soil. At this disease necrosis stains appear on internal tissues of a bark, in a combination to a bubbly surface of a bark on branches and clones. Growth sharply decreases, strongly amazed branches die off, and there is a considerable quantity of annual shoots, whose bark soon starts to become covered necrosis. Strongly damaged trees perish, and poorly amazed reduce productivity.
