Manganese (Mn) are quickly digested and regulates flow of other elements
Manganese (Mn) a microelement that is necessary for plant nutrition, after iron, the quantity in the plant is 0.001%, has the ability to quickly assimilate the plant, move through the organs and regulate the flow of other elements, affect growth processes, change in micro-biological activity, organic matter content agricultural crops, increases resistance to unfavorable factors, improves fruiting. Manganese actively participates in the processes of photosynthesis (the transfer of electrons - due to the ability to change the valence, accumulation of chlorophyll, formation of sugar, vitamins - ascorbic acid) respiration (decrease in transpiration and increase in water regulating ability, transfer of phosphorus from the lower vegetative organs to the upper reproductive organs); metabolism (metabolism of carbohydrates,
Deficiency of Manganesewith insufficient amount of water, it drips on the formation of plastids and the passage of the process of photosynthesis, the plants are damaged by gray patches, while the leaves become light green, the ratio of the elements is disturbed during nutrition, which leads to chlorosis, necrosis (small yellow spots appear on the leaves, to the death of their parts), darkening of the roots, helps to reduce the frost resistance of agricultural plants. The most sensitive to the lack of element: cereal crops (oats, barley) are damaged by gray spot, vegetable (spinach, beet) is observed - spotted jaundice, legumes (beans, peas) - seeds form black, brown spots and fruit-berry crops (apple, peach ) - different necrotic zme of leaf blades, further leads to a decrease in the absence of fruiting. In most cases (for plants, if the manganese is less than 10-25 mg / kg dry weight) leads to a deficit and appears on the soils after liming, at pH 6.0-6.5, at low temperatures, insufficient illumination intensity, high organic content substance, in particular phosphorus and calcium.
Excessive food manganese leads to iron deficiency in the soil. On plants there are chlorosis (on old leaves), on leaf plates - spots with different colors (brown, necrotic) and after a while they curl and fall off, and the cereals lead to "burning out of crops". The excess of manganese in the soil must be controlled, in particular, plants should be fertilized with silicon, and molybdenum eliminates the toxic effect of the element.
Mutual interaction of manganese with other elements
|Antagonists (An excess of one contributes to the deficit of another element)||Sinengists (Improve mutuality of each other)||Blocks the interaction of each other (not recommended to combine together)|
|Fe (iron), Zn (zinc)||-||P (phosphorus), Ca (calcium)|

Ukraine has an agrarian orientation of the economy and in modern conditions one of the most perspective areas for agriculture is the use of organic preparations and is based on the application of exclusively natural components that offers production AGRO.BIO - liquid concentrate GUMAT KALIYA , which helps to rationally and effectively restore the natural components of the main asset - the soil.
In a soil environment, there is not always enough nutrition for plant growth and development, but this disadvantage can be improved by additional fertilization, namely: GUMAT KALIYA UNLIMITED WITH LEONARDITA produced by AGRO.BIO - ecologically safe complex fertilizer and growth stimulator for organic plants that promote soil fertility.
In order to make it easier for you to read our products below, there are articles about potassium humate and multicompules.
