Establishment the key
to unlocking yield potential
The development of a plant's roots, and the
subsequent initiation of yield-determining
tillers, depend on adequate available phosphate
around the developing roots of the young plant.
In the first six
weeks the roots can only access
around 5% of the soil to obtain nutrients. The
very limited mobility of phosphate further
challenges the plant's development.
AVAIL can help your crops
reach their potential.
With the introduction of AVAIL ® Phosphorus
Fertiliser Enhancer into the UK, growers have
the opportunity to harness the value of the
phosphate they are applying, which will help
provide the required available phosphate the plant.
Carrs recommend that whenever phosphate
fertiliser is applied to autumn sown crops,
80%
or more of the P necessary for that crop is
applied pre-emergence as AVAIL-treated P.
AVAIL-treated P will remain accessible by the
plant for the whole growing season, thus will
supply the crop requirements throughout the
life of the crop. This is a significant advantage
over conventional phosphate fertiliser,
which
starts locking up in the soil soon after application.
The extra cost of AVAIL is small compared to
the advantages it offers. Indeed, by increasing
the availability of the phosphate it reduces the
cost of plant-available P by half.
The wheat on the left received AVAIL-treated P,the wheat on
the right standard P. Note the larger plant size and root system
on
the wheat that received AVAIL-treated P.
A new approach to PK fertilisers
for autumn
cereals in which 80% of the P and 20% of the K requirements are
applied in the autumn, with
the balance applied in the spring together with
nitrogen and sulphur.
Why 'PK 80/20' + AVAIL?
The highest nutrient uptake
in establishing
autumn crops is phosphate and calcium
The phosphate in ‘PK 80/20 ’ is
treated with AVAI L , unique phosphate fertiliser
enhancer
Potash uptake is highest in spring, so it
makes sense to apply it in the spring
Potash prices are still very high,so it also
makes sense to ‘spread ’ the purchase of
potash between autumn and spring
How does the 'PK 80/20' + AVAIL system
work?
Establish your soil indexes for P, and Ca.
If you don't know them, contact us for soil
sampling.
Estimate your yield.
Choose the appropriate ‘PK 80/20 ’ +
AVAIL grade (see table below).
For each ‘PK 80/20 ’ AVAIL
grade there is
a corresponding spring NPK +S grade to
apply the correct nutrient balance. We will
contact you to discuss the correct spring
balancing fertiliser for you.

* The recommended application rates above are based on straw
being removed and no slurry or FYM being applied.
The Benefits of 'PK 80/20' + AVAIL
* AVAIL is tried and tested in extensive field trials in the
UK. Contact us for further information.
