Nutrients

August 12, 2017 17:52 | General Information About Plants

all nutrients necessary for the full development of the plants.Each of them has a certain impact on the growth of plants, plays a role in metabolism.Yet, the most important is the presence of a balanced set of all the elements, as this provides a plant assimilation of all components of the complex.

Nitrogen among the most important biogenic macro-elements, without the plant can not exist.Nitrogen is part of protein compounds which are the basis of life, as well as of chlorophyll, with which plants utilize solar energy, absorb carbon dioxide to form carbohydrates necessary for the construction of plant tissues.The presence of nitrogen is probably the main condition for the growth of plants, the formation of shoots and leaves.Plants get nitrogen from the soil, digest it only in the form of ammonia or nitric acid, and very painfully react to the lack of this element.However

change in its appearance, possible diseases and even death of the plant.There are a number of signs in the appearance of the plant, indicating the lack or excess of a particular element.However, often there is a lack of not one but several elements, and then the signs of their disease combined.For example, while a lack of phosphorus and potassium plant does not show the characteristic features of mineral starvation, but its growth is depressed, and often completely suppressed.At strong deficiency of these elements occurs violet color of petioles and the lower part of shoots.With a lack of phosphorus combined with a lack of nitrogen leaves become tough and fibrous, becoming light green in color and grow at an acute angle relative to the escape.As a result of such a complex deficiency of elements plants often cease to bear fruit.With a lack of three elements nitrogen, potassium and phosphorus plants develop weak, their growth is suppressed, they do not bear fruit, fruit in small seeds.Based on the foregoing, we can conclude that critical to the full development of healthy plants is not the absolute content of nutrients in the soil, and the ratio of the main battery.

Fertilizers: types

and applications

soil as a medium of rooting and plant nutrition must have all the necessary for the life and development of plant substances.Just out of the land as a source of support and nutrients the plants derive their force for the growth, flowering and fruiting full.The balance of nutrients in the soil

objective processes of weathering and leaching of elements in the lower layers of the earth under the influence of precipitation and groundwater,

and natural removal of plant nutrients cause a significant depletion even fertile soils

is a complexdynamic relationships mobilizing and binding processes, the exchange of nutrients, fertilizers and the removal of their plants.Getting nutrients from the soil, the plants gradually exhaust their supply, which in intensive cultivation of crops is not replenished naturally.Therefore, to maintain soil nutrient levels sufficient to plant life support, and to prevent its depletion, it is necessary to compensate for the natural processes of plant nutrient removal and washing them in the lower layers of the soil by applying fertilizers, thereby replenishing the stock of items consumed.

Fertilizers are important in plant nutrition: they act directly on the power mode, improve soil properties,

facilitate transfer of nutrients available in the form of plants.The most difficult issue in the practice of applying fertilizers - determine where to draw the line between the deficiency of nutrients when the plant threatens mineral starvation, and an excess of mineral elements, entailing dangerous glut of soil and plants.From the establishment of the border depends on the optimal dosing of fertilizers.The task of creating a balance of nutrients in the soil is very complex.To determine the optimal level necessary to know the amount contained in the soil of nutrients and trace elements to take into account the structure of the soil, level of acidity, which largely depends on the degree of assimilation of certain substances by plants, the degree of soil moisture, the percentage of humus, the climatic conditions and plant needs

nutrients of different groups.Moreover, during the growing period, the plants need for certain nutrients varies depending on plant organs which grow vigorously in a given time interval.The sheet weight and young shoots require nitrogen, potassium and calcium, the root system - phosphorus and magnesium, the colors - nitrogen and phosphorus.Therefore, the changing needs of plants at different stages of development of food items should also be taken into account when determining the rate of fertilizer application.To do this, it is advisable to carry out soil analysis to establish the level of the nutrient content, and then according to the needs of crops to make the missing elements in the form of fertilizer, which in its composition are divided into organic, mineral and organic or complex.
