What plants need for healthy living? Good eating! On this depends not only their normal growth, flowering and fruiting, but also resistance to stresses (frost, drought). The success of growing plants eventually buried in a particular soil and depends on its nature (chemical composition, physical properties, proximity to groundwater, etc.). Change the chemical composition of the soil and enrich it with elements of power can be introduced using a variety of fertilizers. Necessary and significant for plant macro-and micro-elements – these are the batteries, excess or deficiency of which is determined by growth and development.

Nitrogen regulates the growth of plants. Excess causes “obesity”, they do little and rarely bloom bad winter because they do not ripen shoots. Lack of nitrogen is manifested in the fact that the size of leaves decreased, they turn yellow, becoming reddish hue, slowing growth, thinner stems, forming small buds. There is accelerated ripening. A sharp loss of ornamental plants.

PHOSPHORUS Improvement phosphate supply in autumn increases winter hardiness of plants. With the optimum balance of nitrogen, potassium and calcium promotes balanced growth. With the shortage of phosphorus leaves become pale blue and even violet.

POTASSIUM When he was little, decreased turgor of plants, weakens the ability of plants to resist fungal disease. The leaves become brittle, their tips are bent downwards, there is a premature yellowing of the leaves, extending, starting from the top down at the edges, and then between the veins. Later the leaves brown, and die.

Calcium helps the growth of roots. If the shortage of nitrogen, phosphorus and potassium attenuated the development of aboveground parts, then the lack of calcium – the growth of root system. When calcium starvation occurs albication tops of plants, the newly formed leaves are small, curved, with irregular edges. If a strong calcium deficiency top flight dies. Excess calcium in the soil may cause “lime chlorosis – yellowing of the leaves in the period of active growth.

SULPHUR Usually it is sufficient in the soil, moreover, it is made with manure, superphosphate, ammonium sulfate.

Magnesium is part of chlorophyll, activates enzymes, has a strong influence on fruit formation. When magnesium starvation leaves (especially lower) are marble: blanch the veins, leaf tissue acquire different colors – yellow, orange, red, violet. The leaves are starting from the edges, roll and gradually fall. Usually this happens on light sandy soils. Application of fertilizers containing magnesium on such soils makes a noticeable positive effect.

Iron during his absence comes chlorosis of plants and leaves lose green color, the young leaves of poorly developed. Lack of this element may appear only on soils rich in lime. Correct the situation will spray fertilization vitriol 0,2-0,4% concentration with the addition of 0.15 per cent slaked lime. Even better results are obtained by introducing chelates iron.

Note. Chlorosis of leaves can often be not only the result of a lack of some element, but simply lack of good drainage of soils.

The main trace elements in the menu of plants
Sodium increases the yield of crops, increases the sugar content.
HLORusilivaet respiration of plants.
SILICON contained in the ash (20% or more).

BOR with a deficiency in the soil of his dying apical buds, tops of stems, appears rot. Fall off the buds, flowers, and ovaries, dramatically reduces seed yield. Shoots are numerous, brittle, leaves are hard, rough. The positive effect of boron fertilizer primarily manifested in the limed soils.

Molybdenum has a positive effect on plant growth. Its drawback manifests stunting, pale yellow leaf spot. The best result molybdenum fertilizer yield on acid soils.

Manganese with a deficiency primarily affects median leaves: at the surface between the veins there are small yellow spots (mottled chlorosis). Plants do not grow and develop. A characteristic of an excess of manganese – brown spots (necrosis) on leaves.

Copper for strong expression of suffering plants dry, the tips of leaves turn white, the edges are yellowish-gray color, chlorophyll content in plants decreases. Suffice it to small doses of copper fertilizers to prevent this disease.

Zinc is found in all plant organs, but most – at the points of growth and reproductive organs, especially in seed embryos. Zinc deficiency retards growth, the plants produced narrow, curled into a spiral of leaves, leaf veins stand out clearly against a background of green mesh bleached fabric between them. To address the lack of this element in the soil made of zinc sulphate and other soluble salt it.
