The purpose of spring frost nutrition of winter wheat is to ensure balanced mineral nutrition of plants during the spring-summer period of vegetation. Particularly important is to prevent the manifestation of the deficit of macro - and trace elements in the critical phases of plant development: bruising, the period of maximum growth - from the beginning of the exit to the ear to the ear, formation of grains.
The positive effect of nutrition at the beginning of the restoration of spring vegetation (tillering) is maintained until the end of the vegetation, especially affecting growth processes, photosynthesis and plant productivity. The later feeding (in the period from the beginning of the ear eruption to the filling of the grain), the less the effect of the trace elements on yield and the greater - on the quality of the cultivated product. During this period of growth and development of the plant are quite sensitive to the presence of nitrogen, the shortage of which leads to the reduction of the number of stems on the plant, or to the back of the part of the stems in growth in which the complete ear is not formed, and the presence of macro and microelements responsible for the completeness of nitrogen , in particular magnesium, sulfur, copper. This period in our climatic conditions in different years has significant differences in terms of the beginning, duration and temperature regime and the level of moisture available to plants. The second important element necessary for the full growth and development of plants is phosphorus. Sometimes, even in normally developed plants from autumn, in the spring, phosphorus deficiency is manifested through a long period of relatively low temperatures, in which plants can not absorb phosphorus from the soil. In late, poorly digested crops, the lack of phosphorus at the time of vegetation restoration may be one of the main causes of liquefaction. Plants with a weak root system just die. This inconsistency of weather conditions early in the spring leads to stressful events, which significantly affects the formation of the crop. According to various scientific data, the reduction of grain yields as a result of the stress of plants can reach 5 - 20% or even more than the biological potential of seeded varieties.
The company Ecoorganic in 2016 brought to the market several compositions of antistressants containing critical elements and amino acids suitable for the removal of plants from the stress state.
Macroelements of wheat plants are most intensively assimilated in the period from the beginning of the output to the tube before the ear eruption. At this time, plants form the vegetative mass and some of the most important elements of productivity: the number of productive stalks, the number of grains in the ear. In addition to macroelements, cereal cereal plants have a high need for zinc, copper. Copper is intensively absorbed by the plant in the planting and earing phase; Zinc, which is necessary for the growth of interstitials, is absorbed from the phase of planting to tubing. In the growing season depending on the soil and climatic conditions, other trace elements may also be needed.
The fertilizer line for end-root nutrition Ecoline provides the ability to provide plants with all the trace elements in an easily accessible form for plants. The same applies to some of the macronutrients that, during the vegetation period, play a key role for plants, but are temporarily inaccessible due to the low absorption of the root system.
A vivid example is the application of phosphorus phosphorus for foliar application of phosphorus. Phosphite form is quickly digested through the leaves, quickly moves into the plant, stimulates the growth of the root system, which is especially important in the spring. Stimulates the synthesis in a plant of a specific group of proteins phytoalexin.
Based on the above, the company Ecoorganic recommends several variants of its micronutrient fertilization for foliar application of winter crops.
It is intended for producers that, for one reason or another, are not aimed at obtaining the maximum yield of high quality. Includes one or maximum two-fold foliar feeding. In this case, we recommend using complex compositions that include a balanced set of macro and microelements, most important for grain crops.
This is Ecoline Grain Chelaty and Ecoline Magnus Helat . For single use it is better to use Ecoline Grain Chelates at a dose of 1.0 - 2.0 l / ha at the beginning of the phase of the tube.
For two replenings at the beginning of the phase of the output of the tube it is advisable to first use Ecoline Magnesium Chelate in a dose of 1.5 - 2.0 l / ha, and the second fertilizer to make the composition Ecoline Grain Chelates in the ear staining phase in the dose of 1.0 - 2.0 l / Ha.
On areas covered with high reproduction seeds, by the best predecessors (legumes, perennial grasses), where it is planned to obtain a high yield of good quality, extra-root nutrition should be planned taking into account the parameters of laboratory diagnosis in order to better take into account the needs of plants.
The best option in conditions of 2016 for such crops was a three-fold, non-root nutrition of microfertilizers from LLC Ecoorganic.
The first feeding at the beginning of the phase of release into the tube - Ecoline Magnesium Chelate is normally 1.5 - 2.0 l / ha.
The second feeding at the beginning of the earing phase is Ecoline Grain Chelat. Application dose 1,0 - 2,0 l / ha.
And the third recharge in the phase of filling of grain - Ecoline Grain Chelaty - 1,0 - 2,0 l / ha + Ecoline Phosphite K - 1,0 - 1,5 l / ha.
- Intensive +.
It is possible to apply on areas of sown seeds of high reproductions, according to the best predecessors where it is planned to obtain a high yield of good quality, extra-root nutrition should be planned taking into account the parameters of laboratory diagnosis in order to more fully take into account the needs of plants. It is recommended in cases of manifestation of stress phenomena associated with the temperature regime or the negative effect of ZZR.
In a cool, protracted spring, plants have no chance to absorb such a phosphorus that is necessary for them, which leads to inhibition of growth and development of plants, weakening of their competitive ability in combating weeds and diseases. In order to improve the plant nutrition conditions with phosphorus and potassium in the planting phase, we recommend using concentrated phosphate fertilizer in the form of phosphate Ecolaline Phosphite K in a dose of 1.0-1.5 l / ha, which is digested at lower temperatures than phosphates. Another important property of the phosphite form of phosphorus is the stimulation of plant synthesis of specific proteins of phytoalexins, which increase the immunity of plants and inhibit the development of pathogenic fungi.
The following foliar nutrition at the beginning of the phase of the tube - Ecoline Magnesium Helata is normally 1.5 - 2.0 l / ha. At the same time, a manifestation of stress caused by a lack of moisture. To overcome stress, we recommend adding Ecoline Universal Rist-Amino with high free L-α-amino acids in a dose of 1.0-1.5 l / ha.
Feeding at the beginning of ear staining - Ecoline Grain Chelates - 1.0 - 2.0 l / ha.
And the last addition to the phase of pouring grain to improve its quality - micronutrient Ecoline Grain Chelaty in a dose of 1.0 - 2.0 l / ha in a tank mix with special fertilizer Ecoline Phosphite K in the norm 1.0 - 1.5 l / ha. Although our recommendations are based on the results of the application of the microfertilizer company "Ecoorganic" on the fields of different farms in different soil-climatic zones, they can not be considered a dogma. Under real conditions, specific weather-climatic, soil and other factors that can influence the development of culture can occur, and, consequently, a set of microfertilizers and their doses for each individual field may differ somewhat. Here, the professionalism of the agronomist, as well as the help of the specialists of the company Ecoorganic, will help to select the system of end-root nutrition, which according to the quality / valuec indicator will be optimal for the given economy.
We also want to note the following:
All microfertilizers of the company Ecoorganic are manufactured in accordance with the standard ISO 9001: 2015.
Microelements-metals included in our products are in the form of 100% chelates EDTA.
