REQUIREMENT OF PLANTS FOR NITROGEN
Nitrogen is a component of organic connections in plants (fibers, amino acids, nucleinic acids, phosphates, a chlorophyll, glucose, alkaloids, etc.) which majority is executed by exclusively important functions. As the component of fibers nitrogen plays a paramount role in the course of growth and reproduction of alive organisms. As the essential part of a molecule of chlorophyll nitrogen plays the important role in the course of photosynthesis, formation of green mass and formation of fruits and seeds. Nitric connections deeply influence all vegetative organisms: morphology of organs, rate of development, the general biological efficiency, quantity and quality of a crop.
REQUIREMENT OF SEPARATE CULTURES FOR NITROGEN.
Most of all nitrogen from soil is taken with a corn crop, head cabbage and tomatoes. The moderate quantity of nitrogen is taken with a crop of a clap, a sugar and red beet, a potato, a seed of sunflower, wheat, barley, pepper, eggplants, cucumbers, fruit-berry cultures, an apple-tree, citrus fruit crops and grapes.
Least nitrogen it is taken with an oat crop, turnip, carrot, salads, onions, plum, a quince etc.
Crops differ among themselves with rate of mastering of nitrogen in vegetation. In an initial stage of the development of a plant use rather small quantity of nitrogen. However during this period nitrogen is extremely necessary to avoid a delay in growth of leaves. Deficiency of available nitrogen negatively affects development of a root system of plants and as consequence limits access of nutrients to plants.
Especial requirement for plant nitrogen test in a bookmark of reproductive organs when vegetative organs most intensively grow and the main mass of sheet is formed. If during this period there is a lack of nitrogen, the surface of leaves remains small and insufficient for photosynthetic activity, and as consequence of this lack reproductive organs (seeds, roots, tubers, etc.) cannot be supplied in enough with reserve matters, fibers, fats, sugars, etc.
VISUAL SIGNS IN PLANTS CAUSED BY DEFICIENCY OR SURPLUS OF NITROGEN.
Consequences at deficiency of nitrogen accessible to a plant are shown in infringement of formation of a chlorophyll and growth of a vegetative organism. Depending on degree of deficiency of nitrogen there is a change of intensity of colouring of sheet – leaves become pale-green, and then are yellow-green, and then yellow. Plants at first get pale colour, veins of sheet and nearby tissues turn yellow, other parts of a tissue can keep light green colour. Later on leaves the orange or coffee shade prevails, and then leaves die off and prematurely slough. These signs are shown, first of all, on old leaves, and then and on young as nitrogen gradually passes from old leaves to young, for maintenance of growth of young leaves, seeds and fruits.
Because of a delay of process of cell fission in a growing point or in germinating tissues the nitrogen lack reduces the size of a plant, the area of a surface of sheet, quantity and the size of fruits and seeds. Axillaries or accessory buds which could raise productivity of some kinds of plants, either are not formed, or slough in the beginning of the development, or do not reach full development. In all cases the nitrogen lack leads to detention of growth, plants grow small and lignify. Small plants, because of insufficient vegetative mass and a sheet surface,
have weak photosynthetic activity. Therefore the quantity of the sugar synthesised in plants decreases, the general balance of a feed of plants that does not give a guarantee for heavy yield and quality formation green mass, fruits and seeds is broken.
High doses and unilateral entering of nitrogen are given by adverse reflexion on growth, development and efficiency of plants: growth of vegetative mass strongly amplifies, the vegetative period is extended, and amplifies adjournment of nitric organic substances, and leaves are lush develop and painted in dark green colour.
At many crops, high doses of nitrogen lower quality of cultivated production, and at vegetable cultures and a potato palatability worsen. At grain crops, at high doses and unilateral entering of nitrogen, the exit of straw instead of productivity of grain, contrary to a violent growth of plants increases, and in a plant dry season are strongly amazed with diseases (Field tests see).
DEFICIENCY OF NITROGEN AT CULTIVATION OF TOMATOES.
SYMPTOMS: Slow growth of plants, occurrence yellow chlorosis on old leaves. At greater deficiency of nitrogen of a plant become pale-green with small leaves and fruits. At sick plants nitrate nitrogen about 0,1% in a solid, when at healthy – about 0,5-1,5%.
THE DEFEAT REASON: Deficiency of nitrogen in soil. Application of straw or dung with the big content of straw. Cultivation of tomatoes on clay or sandy-argillaceous poor soils.
PROPHYLAXIS: Entering of nitrogen into soil at cultivation of tomatoes. A foliar top dressing of tomatoes the OM fertilizer "NITROHUMATE" in a dose of 3 l/hectares, or 0,3 % a solution.
DEFICIENCY OF NITROGEN AT CULTIVATION OF CUCUMBERS.
SYMPTOMS: There is yellowness on all plant which begins with leaves. At first leaves become light green, then flavovirent which gradually dry up. Fruits grow small and dark.
THE DEFEAT REASON: Deficiency of nitrogen in soil. Cultivation of cucumbers on clay or sandy-argillaceous poor soils.
PROPHYLAXIS: Entering of organic fertilizers – bio-paste "FERTILITY". Overcoming of deficiency of nitrogen through a foliar top dressing of plants the OM fertilizer "NITROHUMATE" in a dose of 2-2,5 l/hectares, or 0,2 % a solution.
DEFICIENCY OF NITROGEN AT POTATO CULTIVATION.
SYMPTOMS: Leaves turn yellow, new leaves grow the small. Growth of plants stops.
THE DEFEAT REASON: Deficiency of nitrogen in soil.
PROPHYLAXIS: the Choice of rich soils at potato cultivation. Entering of nitric fertilizers. A foliar top dressing of plants the OM fertilizer "NITROHUMATE" in a dose of 3-3,5 l/hectares, or 0,3 % a solution.
