Grains only Grains and straw

Winter grains 5,6 11,8

Spring grains 13,7

Źródło Potash Development Association, UK, 2005

Peak demand in fild of wheat, giving some 8 t grain yield,

shortly before flowering, can achieve up to 10 kg K2O a day

and accumulation raches some 200 kg/ha at this time.

3-4 treatments

I: 4-6 kg/ha at spring vegetation restart. Summer crops – tratment

at tillering stage (BBCH 21-29)

II: 4-6 kg/ha at flag leaf. Malting barley – tr-tmnt when ear visible.

IIa: 4-6 kg/ha some week or two after II, if high gluten content is

demanded.

IV: 2-3 kg/ha at last autumn foliar treatment.

That supplies plant with

potassium and sulphur but first

of all potassium supplied with K-

Leaf reduces drought stress

allowing the plant to absorb

more nutrients from soil.


Oilseed rape – demands for potassium

Oilseed rape needs some 80-85 kg K2O for 1 t of grain yield.

About 1,3 – 1,6 kg K2O per 1 kg N fertilisation.

About 20% of total needs are to be accumulated before winter

Well K-supplied OSR has some 3-6 C° better frost resistance.

Spring K shortages hardly ever show any visual effects.

Very high demand for S – similar to P.


OSR – K assimilation dynamics

3 treatments

I: 4-6 kg/ha at spring regrowth.

II: 10-12 kg/ha at green bud phase.

III: 2-3 kg/ha at last autumn foliar treatment.

Potato demand for potassium

Potato usually needs some 6 kg K2O per 1 t of

tuber yield.

Highest demand during 1 month after tuber

initiation.

After floering accumulation of potassium slowes

down and more potassium transfers from leafs to

tubers.


When potato needs potassiu most?

I: 4-6 kg/ha at when tubers are of some 10-15 mm diameter.

II – IV: 4-6 kg/ha at each consequent foliar fungicide

treatment for 4 weeks after Ist treatment

V – VI: 4-6 kg/ha additionally during tubers ripening (july –

early august), especially if high dry matter is requested.

can be mixed with:

Fungicides, insecticides, other foliar fertilisers.

We recommend to apply mixed with MgSO4

Natrium borate – it dissolves in K-leaf solution by

far faster than in pure water.

● It can not be mixed with calcium (Ca) sources,

however it is fine to use K-leaf in hard water.

● We do not recommend to use with herbicides.
