Spring cereals & winter cereals

Cereals demand for micronutrients

The cereals, including wheat, barley, rye, triticale and oat have a certain demand for trace elements in order to get the most of their yield potential. Based on an average yield of 80 dt/ha, the nutrient removal of manganese will be 600 to 1000 g/ha, copper around 50 to 150 g/ha, zinc roughly 250 to 350 g/ha and boron around 50 to 100 g/ha.

Even with a sufficient level in the soil and an application of manure - many field crops suffer from “hidden hunger”, which is confirmed by many plant analyses done in the last years in Germany. There are many reasons for the undersupply with main and micro-nutrients. Most important will be the nutrient availability for plants.

Soil-pH-value and weather conditions

Micro-nutrients, except molybdenum, are less plant-available when soil pH is high. Also, dry conditions or cold temperatures can reduce the availability and the uptake of nutrients. The application of micro-nutrients via the soil will be less effective. The foliar sprays in these instances ensure precise application of the right nutrient(s) at the right time and will be the most effective way to feed the crops. Lebosol foliar fertilisers are widely mixable with crop protection products to make treatment easier and more convenient.

Combination of manganese, copper and zinc in cereals

Manganese, copper and zinc are classified as key trace elements in cereals production. The synergistic relations of these three elements, mean that the uptake of one of these nutrients increases with the application of the other micro-nutrients. A perfect combination of these three elements has been achieved in Lebosol®-QuadroMaxS SC. The best effects in winter cereals have been observed with 2 consecutive treatments in Autumn and Spring.

Under specific circumstances and soil conditions (high humus content, pH-values higher than 6.5) an additional application with manganese (Lebosol®-Mangan 500 SC, Lebosol®-Mangan Gold SC) might be beneficial.

Improving resistance against diseases

Foliar application with VITALoSol® GOLD SC will strengthen the plants against unfavourable weather conditions and diseases. The combination of sulphur, copper and manganese in VITALoSol® GOLD SC will have a positive effect on winter hardiness, stress and disease tolerance.

Safe to the crop and salt-free ear treatment

Lebosol®-MagSOFT SC has been developed especially for late application. This suspension is much more receptive to the leaves compared to granulated magnesium sulphate products. Field tests have shown a much higher nutrient efficiency compared to unformulated salts based products.

To enhance protein with magnesium and sulphur

Leaf analysis have shown an increase of sulphur deficiency in winter cereals. This is caused by the decline of sulphur availability from the atmosphere. S deficiency symptoms occur first in young leaves, which becoming pale yellow.

Prolonged undersupply results in reduced protein in grain.

Not to confuse it with an undersupply of nitrogen – this will be visible on older leaves.

In addition to soil supplied sulphur, a foliar treatment with Lebosol®-Schwefel 800 SC or Lebosol®-MagSOFT SC will enhance yield and quality.

An optimal sulphur provision optimises the N-utilisation, yield and improves healthy crop development. The late application of sulphur in wheat will increase the protein content.
