Claims of grain on micronutrient supply

Our types of grain, including wheat, barley, rye, triticale as well as oat have, in addition to the demand on  main nutrients as  nitrogen, phosphorus, potassium and sulphur, also a high need in micronutrient supply. Based on a harvest production of 80 dt/ha, the withdrawal of manganese is 600 to 1000 g/ha, copper is 50 to  150 g/ha, zinc is 250 to 350 g/ha and  boron  is 50 to 100 g/ha. When viewing the extracted amount, these micronutrient denials appear low first and the application of manure promises a balanced nutrient care

– an assumption, which is frequently deceptive in practice. Even with good contents in the soil analysis many stocks show nutrient lack symptoms, which is reflected in numerous plant analyses of grain cultivation in the recent years in Germany. The reasons for lacks in main nutrients and micro-nutrients can be very versatile, they lie most frequently in the nutrient availability in the soil solution.


Soil-pH-value and                                                  weather conditions

Micro-nutrients, except molybdenum, are difficultly plant-available particularly with high pH values in the soil. Moreover, aridity, stagnant water and cold can lead to the fact that the plants are not able to absorb the required existing nutrients. The administration of trace nutrients via soil, especially manganese, is not recommended. In view of the above the existence is reached, but the mobility and admission via plant is not covered. Therefore the foliar trace nutrient fertilization is established in practice. Various measures of plants protections in autumn and spring allow a simple, uncomplicated administering without separate sprayings.


Combination of manganese, copper and zinc in grain

As already mentioned, manganesecopper and zinc belong to the most important trace nutrients in grain cultures. With the fertilization of these three elements due to  the basis of nutrient antagonisms a so-called „sleigh effect“ has shown, which means that the admission of one of these elements is promoted  by a multiple by the parallel dose of the other mentioned elements. A simple combination of these three nutrients is received by the application of Lebosol®-Triple SC oder Lebosol®-QuadroS SC. Give ideally a dose in autumn and in spring. The nutrient need is covered enough by this measure. At specific locations, like e.g. fen soils (pH-values higher 6,5) with a particular need in e.g. manganese, the rise of  the nutrient amount is recommended with a separate dose of mangnese.


Stabilization of resistivity against diseases

For the  application in autumn, there exists no admittance for fungicides in  grain.  To give better conditions to the plants against the pests, a foliar application with VITALoSol® GOLD SC is recommended. The nutrients sulphurcopper and manganese combined in  VITALoSol® GOLD SC  have a positive effect on winter hardness, stress tolerance and on stabilization of the resistivity against diseases.

Salt-free, leaf-compatible ear treatment by a mild formulation

The formulation of the nutrient suspension Lebosol®-MagSOFT SC has been developed specially for a late dose, because compared to salty, granulated products, there exists no danger of foliar combustions of the grain cultures. Tests have shown a frequently higher nutrient efficiency compared to unformulated salts.


Magnesium and sulphur for the promotion of the brute protein yield

In recent years a clear sulphur shortage appeared frequently in winter barley crops.

By the decline of the sulphur entry from the atmosphere and strong erosion by autumn rains, many surfaces show light yellow discolorations in young leaves.

A clear difference to the nitrogen lack is visible, because this appears in older sheets with bright discolorations.  To a sufficient basic fertilization with sulphur via soil a foliar fertilization with

Lebosol®-Schwefel 800 SC or Lebosol®-MagSOFT SC in EC 31/32

is recommended for the direct recovery of these sulphur shortage symptoms in grain.

A good sulphur supply promotes at the same moment the nitrogen admission, that is why this should be protected fundamentally for the formation of yield. An administration of magnesium and sulphur to the ear treatment  is favorable for the protein formation and should be executed by the application of  Lebosol®-MagSOFT SC.

The application of formulated suspensions is economically as well as agronomically an advantage for the user.
