When sowing winter
wheat (winter barley, triticale or rye) in the autumn
- it is not profitable to apply nitrogen
fertilizers to the rows - it is a waste of money! At the photo - late
germination of winter wheat after sunflower in a temperate climate (dry,
cold continental climate)
Applying nitrogen
fertilizers to rows when sowing winter wheat
in autumn (also:
nitrogen fertilizers - any top dressing, side dressing, application of
UAN or ammonia in autumn)
-
is not economically profitable.
Due to the lack of knowledge and fake information, this
practice is common only in Belarus, Kazakhstan and Russia, and
unfortunately - is still present in Ukraine. In the USA, Canada, Europe,
the countries of the British Commonwealth do not do so! Farmers and
agro-industrialists who count their money do not apply nitrogen
fertilizers when sowing winter wheat in autumn!
Nitrogen
fertilizers when applied in the autumn
are washed away, leached but do not pay off with an increase in yield.
Applying nitrogen
fertilizers when sowing winter wheat,
winter barley or winter rye is the same fake as fertilizing by frozen
soil. Such investments do not pay off!
For the same reason, fertilizing
winter wheat with nitrogen fertilizers in the autumn
do not effective.
But to apply phosphorus
fertilizers when sowing winter wheat in
rows - very profitable, because it contributes to the good development
of the root system and increase resistance of plants to freezing in
winter. You can also give other nutrients (but not nitrogen), based on
soil analysis and a
properly calculated fertilizer system.
The rate of fertilizer application for
the winter wheat yield of
7
t/ha and for the 10-12 t/ha yield will
be very different! It is necessary to calculate everything correctly!

Consulting for this!
Spreading fertilizers (top dressing)
before sowing is less cost-effective than applying them at the same time
as sowing.
It is recommended to apply
phosphorus fertilizers in autumn, when
sowing winter wheat (winter rye or winter barley), it is not
recommended to apply nitrogen, the
minimum norms are indicated below:
phosphate fertilizer double 40-50 kg/ha
(35-45
lbm/ac), contains 43% or 46%
P2O5,
or
liquid complex
fertilizers (LCF) containing phosphorus
(Р), for
example, LCF P18K18,
rate must be calculated by P content, planning
yield and soil & climatic conditions + possible add K, S, Mg and
micronutrients to liquid fertilisers
often make other fertilizers (not
nitrogen)
give phosphorus, potassium fertilizers
and other nutrients, the introduction of which in the fall when sowing
is justified.
Phosphorus fertilizers are recommended to be given
in a row when sowing winter wheat, winter canola
and winter barley, even when there is enough phosphorus in your soils!
Always add a small amount of starting
rate of phosphorus (P) to the row when sowing, regardless of the soil
test. If no starter fertilizer is applied to the row, then the rates of
phosphorus (P) on soils with a high and very high phosphorus content
should be zero! At the photo - late sowing of hybrid winter rye in
continental
temperate climate and light black soils - will be
frozen after some days
If, for any reason, you want to
give nitrogen fertilizers in the fall in rows when sowing winter crops, then
give the very minimum dose of nitrogen, or better to focus on using of other
nutrients that will not be lost if they are applied in time of sowing.
Also, the application of
nitrogen when sowing spring wheat or spring barley will be an effective
solution!
