Optimise resilience to cold and nutrient uptake
Potassium performs two important tasks in the growth of wheat: it regulates water levels and protein metabolism. If the plant has a sufficient supply of potassium, it has a lower water consumption, withstands dry periods better and develops higher resilience against the cold.
A potassium deficiency in wheat and other grain varieties exhibits symptoms similar to an excess of nitrogen:
- lack of sturdiness
- higher susceptibility to disease
- wilting symptoms
- chlorosis on older leaves
- low storage of reserve substances in the grain
How can SOLU K 52 positively affect the growth and crop yield of wheat and other varieties of grain?
The advantage of leaf fertilisation with SOLU K 52 is the direct and rapid absorption of nutrients into the metabolism of the plant tissue. The energy consumed for conversion within the plant remains low. Moreover, the absorption of nutrients is not dependent on environmental factors such as soil humidity.
In addition, SOLU K 52 can be combined with pesticides and growth regulators and leads to beneficial synergy effects in many cases: in dry conditions, the high concentration of the combined sprays reduces vaporisation and thus the evaporation of the active substances. This, in turn, reduces the use of pesticides and has positive effects for the ecosystem.
When applying SOLU K 52, however, the plant’s absorption capacity is limited. Overdosage can lead to leaf burn. This is why it’s important to observe the relevant concentration limits, particularly when splitting into multiple doses.
How can SOLU K 52 positively affect the growth and crop yield of wheat and other varieties of grain?
Early leaf fertilisation with SOLU K 52 can be carried out if heavy rainfalls or prolonged periods of drought have had a negative impact on the nutrient balance in the soil even before sowing.
Similarly, if prolonged dry spells or heavy rainfalls occur within the first month after sowing, we recommend initial leaf fertilisation with SOLU K 52. After all, deficiencies in this early stage are very difficult to compensate in the further growth of the plant.
In the generative phase, there is a generally increased need for potassium and sulphur (as sulphate). Leaf fertilisation in this stage can have a significantly positive effect on the quantity and quality of the yield.
With a spray rate of 400 l/ha, we recommend a fertiliser concentration of 2 kg/l in the spray mixture and a fertiliser quantity of 4 kg/ha.This equals a nutrient content of 2.2 kg/ha K2SO and 0.7 kg/ha S.
