Symptoms of failure of plant nutrition

to annually collect high yields of good quality fruits and berries, you need to learn how to efficiently apply fertilizers.The plant is necessary to create conditions under which it would receive the batteries in the right quantities and for him in certain proportions.Requirements of fruit and berry crops are very specific to the power supply.

Horticultural Crops relatively less demanding on soil fertility, they positively respond primarily with nitrogen and potassium.

accumulating in the wood aboveground part and root system of a significant amount of nutrients, trees use them with a lack of income from the soil (there is the so-called reutilization).However, it can not serve as a reason to not to make fertilizer.For example, the movement of phosphorus in growing young bodies is accompanied by the demise of the old fabric, which reduces the resistance of plants to unfavorable conditions.If you do not replenish the reserves of phosphorus in the soil, it will manifest symptoms of the defect.This also ap

plies to other batteries.

Black currant and buckthorn require elevated phosphate diet;gooseberries, red and white currants - potash, raspberries - nitrogen and potash.

occupies a special place the strawberries - it can be successfully grown on relatively poor soils, but with a certain predominance of potassium over the nitrogen and phosphorus.

Poor nutrition leads to disruption of metabolism in the plant.With a sharp shortage of a particular element there is a change in its appearance.In this case deficiency of each element has its own characteristic symptoms.This deficit under certain conditions can occur in any soil, but most often on the light sandy and sandy loam (potassium, magnesium, sulfur, iodine, bromine), on calcareous or pereizvestkovannyh (manganese, boron, zinc), on zafosfachennyh - when making excessive doses of phosphorusfertilizers (zinc), on peat (copper, manganese, boron, potassium).Nitrogen deficiency can manifest itself in any soil and at any time of the year.

Symptoms of some macro- and microelements in fruit and berry plants

batteries

Signs of a lack of the element

plant parts and the most dramatic signs of (by plantsindicators)

N

nitrogen

Melchanie leaves, loss of intense green color, yellowing, appearance of orange and red hues, early leaf fall.Growth is depressed, poor flowering.Usoobrazovanie in strawberry bad

On older lower leaves from the beginning of the growing season (strawberries, apples, potatoes, tomatoes)

P

phosphorus

leaves Painting dull, dark green, sometimes withbronze tint, characterized by the emergence of red and purple hues.Wither the leaves turn dark, sometimes black.Tightening the flowering and ripening.Early defoliation

On older lower leaves (apple, black currants, strawberries, tomatoes)

By

potassium

Leaf Color from blue-green to dull chlorotic.The most characteristic feature - the appearance on the edges of the leaves wither rim tissue - boundary "burn."lamina growth uneven, leaves shriveled

On older lower leaves, often in the middle of the growing season (apple, currants, raspberries, strawberries, tomatoes, beets)

Ca

calcium

whitening youngleaf curl leaf upward dying apical buds and shoots, defoliation and ovaries

at the beginning of the growing season on young tissues on the tips of shoots (strawberries, apple, currants, gooseberries, cucumbers, cabbage)

Mg

magnesium

Leaves yellow, red or purple, their edges and veins for some time remain green (interveinal chlorosis).Painting like a "Christmas tree".Listopad begins early with the lower part of shoots

On older lower leaves, often in the middle of the growing season and especially during drought (apples, potatoes, tomatoes)

M n

manganese

Occurrencewhite, pale green, red spots as in magnesium starvation, but on the top, and not on the lower leaves.Interveinal chlorosis

on upper leaves, especially at their base (potatoes, cabbage, beets)

In

boron

Chlorosis of young leaves, they melchanie, twisting, early subsidence.Enhanced development of lateral buds at the apical braking.Flowering and tying weak, fruits ugly

on younger parts of plants, and particularly sharply in the dry summer (apple, raspberries, beets, tomatoes)

With u

copper

Weakening growth, braking and sometimes death of the shoot apex, lateral buds awakening.The leaves are variegated, pale green, limp, ugly

on younger parts of the plant, especially in the dry hot summer (apple, plum, lettuce, spinach)

Zn

zinc

small leavesnarrow, due to interveinal chlorosis - mottled, wrinkled, thin shoots, shortened.Characteristic "rosetteĀ»

On older leaves, especially in the spring (apple, tomato, pumpkin)

However, no less harmful excess food.Excessive nitrogen nutrition, particularly in the second half of the summer, stretches between pot one plant the wood does not ripen, and eventually increases the risk that they freeze slightly in winter.Excess fertilizer results in strawberries, the strong development of leaves at the expense of fruiting and, indirectly, to the development of botrytis.Excess boron and molybdenum in plants cause toxemia.
