ENTEC® – THE STABILISED MINERAL FERTLIZERFOR OPTIMAL NITROGEN EFFICIENCY
Properties
ENTEC®-fertilizers are nitrogenous mineral fertilizers
containing the ammonium stabiliser DMPP*. This slows
down nitrification and ‘stabilises’ the ammonium nitrogen
in the fertilizer in the soil. In addition to the stabilised
ammonium nitrogen, ENTEC® always contains a propor-
tion of nitrate for fast plant uptake. ENTEC®-fertilizers are
available in the form of nitrogen-sulphur fertilizers and as
complex fertilizers on the basis of Nitrophos®/Nitrophos-
ka®. All ENTEC®-products are characterised by the high
quality of their granule, which guarantee problem-free
storage and precise application.
AbsorPTIoN oF AMMoNIUM NITroGEN AND NITrATE NITroGEN
Ammonium NH4+ Nitrate NO3
–
Nitrate nitrogen is always dissolved in the soil water and is carried to the roots passively. Nitrate there-
fore takes effect quickly. High rainfall can leach
the nitrate out of the rooting zone.
Ammonium nitrogen is nearly immobile in the soil. The roots have to grow into the nutrient. Absor ption is even and constant.
Effect
Ammonia-nitrogen is less mobile in the soil than nitrate. It
is bound to the surface of clay and humus particles. This
explains the slow, almost reserved availability of nitrogen
and the uptake of ammonia by the roots, which proceeds
steadily and consistently. Nitrogen in the form of nitrate, on
the other hand, is dissolved in the liquid soil phase and is
easily able to reach the plant roots. The uptake is via the soil
solution, which is why nitrate works quickly, however it is
more easily washed out of the rooting soil area by high rain-
fall. Unlike this, Ammonia-N stays longer in the rooting zone.
both forms of nitrogen can be used by plants and it is
favourable for plant growth if plants can be nourished with
both forms of nitrogen. Due to the subsiding nitrification
processes in the soil, however, all forms of nitrogen are
converted relatively quickly into nitrate depending upon
the soil conditions, so that the nourishment of plants with
nitrogen mostly takes place via nitrate.
by the stabilisation of the ammonia nitrogen with ENTEC®
fertilizers, ammonia is no longer subject to rapid nitrification
and plants are in a position to assimilate ammonia nitrogen
over a longer period of time. This combined nitrate and am-
monia nutrition is advantageous for plants – the efficiency
of nitrogen fertilizers is thereby increased.
ENTEC® – the ammonium stabiliser DMPP
The ammonium is stabilised by the active ingredient DMPP.
In the soil, ammonium is transformed by microorganisms
via nitrite into nitrate. Depending on the properties of the
soil and the temperature, this transformation (nitrification)
normally occurs within hours or days. DMPP delays the
release of nitrate by up to ten weeks and adjusts it to plant
growth. The ENTEC® nitrogen is protected against the ef-
fects of displacement and being washed away. That is why
ENTEC® fertilizers are also suitable for watersheds. DMPP
specifically targets nitrosomonas bacteria without affecting
other soil organisms.

The nutrients in ENTEC® Nitrogen is present 30 – 50% as nitrate nitrogen and ap-
prox. 50% – 70% as stabilised ammonium nitrogen and the
case is similar with calcium ammonium nitrate. That is why
ENTEC® works quickly and persistently. Gaseous nitrogen
losses which occur, for example in the case of urea, are
largely prevented.
Phosphate is completely solubilised and present 60% –
80% in water-soluble form. This part ensures that young
plants have a head-start when it comes to spring growth.
The remainder of the phosphate is soluble in ammonium
citrate and is available during later growth periods.
Potash is present in a water-soluble chloride or sulphate
form that is available to plants. The potash supply ensured
by applying nitrogen and phosphate in early spring im-
proves efficiency.
Magnesium is present 80% in water-soluble form. This
ensures that the plant‘s current needs are met and, if the
soil is well-supplied with magnesium, makes a contribution
to maintenance application.
sulphur is present in a moderately soluble sulphate form
that is quickly available to the plant. The current sulphur
requirement is covered and efficiency is improved.
DMPP protects the ammonium nitrogen from being washed
out – it can remain in the soil for longer and the plants can
better use of the nitrogen. research carried out at the Insti-
tute of soil Technology in bremen shows that ammonium-
stabilised fertilizers reduce nitrate loads in the soil considera-
bly. In a series of experiments conducted by the Institute, the
nitrate discharges via seepage water were reduced almost to
the level of an unfertilized field.
ENTEC® protects against nitrate shifting With no or poor root penetration, the danger of nitrate
shifting into lower soil levels exists.
This applies primarily
To light soils,
To soils without plant cover (e.g. during the cultivation
break between two crops),
In the case of still poorly developed plants (e.g. during
juvenile development) and
in the case of crops with widely sown seeds or plants
(e.g. corn, beets, some species of vegetables, potatoes
prior to row closure).

ENTEC® – FOR FLExIBLE LABOR MANAGEMENT
ENTEC® fertilizer systems allow you greater flexibility when
planning the application of fertilizer: fertilizer application
dates can be brought forward or together without having
to reckon on lower yields. Farmers can better exploit the
ability of the soil to be worked and periods of time when
there is less work to do, while in more labor-intensive
periods they can reduce the workload on their farms.
Work peaks can be broken and remedial costs due to
off-schedule work avoided. Time becomes available for
other agricultural work that has to be completed by specific
deadlines or work that needs to be done in other areas,
such as animal husbandry.
HUMAN lAbor rEqUIrEMENT IN DIFFErENT FErTIlIzEr sysTEMs
An example: Farm size 600 ha: 20% sugar beet, 5% rapeseed, 65% winter cereals, 10% summer cereals. The diagram
shows the benefits of an ENTEC®-fertilizer system as compared to conventional fertilization. The surface to which fertilizer
is to be applied is reduced by about 40% in this example. No additional work is involved in the first application. The time
devoted to fertilization measures from April to June is significantly reduced.

The effect of nitrogen-fertilization always depends on the
weather. As a result of climate change, more and more
extreme weather events are occurring, which increases the
uncertainty felt by farmers with regard to the application
of fertilizer. ENTEC® helps to minimize the cultivation risk –
regardless of the weather:
secure N-supply through early fertilization with subse-
quent dry conditions – especially during dry springs and
early summers.
optimal N-supply when weather conditions are normal.
Protection against surface run-off and leaching in wet
years and when there are high levels of precipitation.
The early fertilization of crops with ENTEC® fertilizers
ensures that nitrogen is supplied when it is needed over
a longer period. The nitrogen in the fertilizer is protected
against leaching and/or the effects of displacement. No
detrimental overgrowth of crops occurs.

During the past 100 years there have been changes in
annual precipitation worldwide – on the one hand in the
volume and on the other in its timing and distribution.
Extreme weather events like heavy rains or hail will go
on increasing in this context, which makes it ever more
difficult to calculate how to organise work on a farm.

ENTEC® IMPROVES ROOT-EFFICIENCY
In principle, plants can absorb both nitrate nitrogen and
ammonium nitrogen via their roots. The stabilisation of
the ammonium nitrogen in ENTEC® enables the plants to
absorb more ammonium. The side-effect: The pH value
in the immediate area of the roots falls, regardless of the
physiological lime effect of a nitrogen-fertilizer (lime con-
sumption value).
The effect of partial lowering of the
pH value and better root penetration
is shown by the root absorption
in the research of Prof. römheld,
University of Hohenheim, stuttgart.
pH value
This results in increased availability of nutrient compounds
that are bound into the soil and are highly insoluble: For
example, phosphates, which are bound to calcium and
the trace nutrients manganese, copper, zinc, iron and
boron. This effect persists for up to ten weeks after the
fertilization date and, during critical growth phases,
improves the supply of the plants with the aforementioned
nutrients.

The composition and effect of ENTEC® simplifies the
process of nitrogen-fertilization considerably: operations
can be combined without jeopardising the plant’s supply of
nitrogen. Crops that with conventional fertilization require
e.g. three sets of applications now only need two.

The application recommendations for special and agri-
cultural crops on the following pages are examples and
are based on current knowledge. The volumes stated are
expressed in kg N/ha. Depending on the site conditions
(soil conditions, precipitation levels and ability to supply
additional N), the volumes are based on our own experi-
ence and regional recommendations. The criteria for
good professional practice (incl. Nmin) should be followed
and applied during decision-making. When using NP and
NPK fertilizers, the findings of soil analysis with regard to
phosphates and potash are of great importance. ENTEC®
fertilizers can be integrated into all forms of farming and
fertilizer systems.

GENERAL NOTES ON APPLICATION

ENTEC ® – Application recommendations
ENTEC® FOR FRUIT
Nowadays, consumers expect consistently ripened
products of uniform quality. This is both a question of
their appearance and the substances they contain.
ENTEC®-fertilizers promote marketability and ensure high
yields: The rapid start effect and the long-lasting supply
of nitrogen through ammonium, in line with plant growth,
result in compact, uniform plant development. This is
accompanied by a uniform colouring and size of the
harvested vegetables. The content of flavour-bearing ele-
ments, minerals and vitamins increases while the nitrate
content decreases. The size of the N-doses is based on
the requirements of the crop. The quantity of nitrogen
already contained in the soil have to be deducted. The
same also applies to the mineral nitrogen to be expected
from the harvest residues of the previous crop. Fertiliza-
tion occurs during planting or after the growth of sown
vegetables. While two doses are normal, ENTEC® can be
applied in one dose.
Crop management in vineyards is optimised so that the
best grapes can be harvested for the creation of high-
quality wines. A high standard has already been attained
with current cultivation methods for grapes. The challenge
is now to maintain these standards by reducing the amount
of work and protecting nutrients from the fertilizers against
being leached.
The slow release of nitrate nitrogen from ENTEC® fertilizers
when it is needed eliminates the risk of a high, uncontrolled
supply of nitrogen even with a low level of nutrient extrac-
tion. ENTEC® NPK-fertilizers supply the plants with all the
important nutrients harmoniously, in a way that is tailored to
the special needs of grapes.
As the soil is often dry at the time the grapes require the
nitrogen (blossoming – berry touch), the effect of fertilization
measures at this point in time is difficult to evaluate. The
key factor is optimally utilising the relatively small quantities
of nitrogen applied in fertilizer.
With ENTEC®, fertilization already occurs during the 3rd
to 6th leaf stage. Thus the existing moisture in the soil can
be used to dissolve the nutrients. The risk of nitrate being
leached is reduced considerably when ENTEC® is used.
The grape is supplied optimally, in line with growth. After
ENTEC® fertilization, additional fertilization is not needed
with normal growth.
When cultivating fruit, a balanced and adequate supply of
all nutrients to the plants is essential. Harvests with consist-
ent sorting and colouring are required. With the mineral fer-
tilizers from the ENTEC® product family, fertilized products
meet these requirements: the high proportion of stabilised
ammonium nitrogen guarantees yield and promotes qual-
ity. Nitrogen losses due to high levels of precipitation or
frost-protective irrigation are reduced, while the efficiency
of fertilizer application is increased. The nutrient require-
ment in the cultivation of pome and stone fruit is relatively

low and, in most farms, lies between 40 and 80 kg N/ha.
Normally, the required volume of fertilizer can be applied in
a single dose shortly before blossoming. The properties of
varieties, forms of cultivation and the fruit set too should be
taken into consideration when measuring the volume of fer-
tilizer and, in some cases, a second dose may make sense.
As far as the supply of nitrogen is concerned, soft fruit has
special requirements.
When cultivating sugar beet the goal is to achieve a high
sugar content. The level of nitrogen-fertilization is based
on the optimal white sugar yield. Depending on the soil
content and additional supply of nitrogen, the beets receive
between 80 and 120 kg/N. The N-requirement is low dur-
ing the first few weeks after sowing. Most nitrogen is not
absorbed until row closure. The delayed delivery of nitrate
from ENTEC®-fertilizers corresponds to the N-requirement
of beets while no nitrogen losses need be feared.

The level of nitrogen fertilization depends on the variety and
intended use. Potatoes for human consumption, those for
processing or starch potatoes have different requirements.
Depending on the ability to supply the soil additionally,
the recommended volume of nitrogen lies between 80 and
100 kg N/ha. The absorption of nitrogen is restrained at the
start of growth. It only increases following the fourth week
after the start of growth.
ENTEC®-fertilizers are especially beneficial to
potatoes due to their active principle:
Needs-based volumes of nitrogen are available.
reduced nitrate content in the tuber, improved
storage life.
local lowering of the pH value in the root area due to
the absorption of ammonium improves the availability of
phosphates and trace nutrients.
Increased tolerance of scab through improved availability
of manganese.
No reduction in the starch content with increased yields.
More marketable goods since there are fewer oversized
or undersized potatoes.
Thanks to the action principle of ENTEC®-fertilizers, the
entire N-volume can be spread before or after planting or

When cultivating wheat the challenge is to promote those
properties specific to particular varieties that determine
quality and yield (number of ears, number of grains, grain
weight) through targeted crop management. There is no
uniform crop management strategy. This is based on the
intended increase in yield and the characteristics of the site.
With ENTEC®-fertilizers, applied on their own or in combina-
tion with other straight nitrogen-fertilizers, there are a wide
variety of interesting combinations which meet the demands
of particular sites and the cultivation goal.
Additional benefits of the ENTEC®-fertilizer system:
Fewer fertilization measures.

essential. It is recommended that CAN be additionally used
in late fertilization.

The quantity of nitrogen to be supplied from the fertilizer
should be based on the nutrients removed by the harves-
ted crops and the Nmin-content. In farms that keep animals,
the nutrients obtained from livestock manure and the
additional supply from nitrogen that has been enriched in
the soil should be taken into consideration. During the first
few weeks after germination the nitrogen requirement is
extremely low. Until this time the level of root penetration
in the soil is slow and the nitrogen is subject to the danger
of shifting. At the end of May the N requirement increases
sharply with growth: until flag leaf emergence the nutrient
uptake within 4 weeks is about 140 – 160 kg/ha N (approx.
50% of the entire requirement, approx. 5kg/ha/day).
Side-dressing with ENTEC®:
The corn responds positively and develops quickly after
side-dressing with stabilised NP-fertilizers. With side-

ENTEC® FOR SUMMER BARLEY/MALTING BARLEY
The control of nitrogen-fertilization plays a decisive role in obtai-
ning good quality for malting barley and feed barley. Good quality
malting barley is characterised by a high proportion of whole
barley and a lower protein content. This can only be guaranteed
by restrained nitrogen-fertilization, which ensures the lower protein
content demanded by producers. The level of nitrogen-fertilization
is within strict limits. The case is different with feed barley where a
high protein content is desirable. Here higher N-volumes result in a
higher yield with higher protein contents. both cultivation goals can
be achieved easily with ENTEC®.
In the case of ENTEC®-fertilizers it is possible for the entire N-
volume to be spread in one dose shortly before or after sowing.
The N-supply is thus ensured throughout the entire vegetation
period. larger-scale losses due to shifting need not be feared.
regardless of the weather condtions, the nitrogen from the fertilizer
remains in the topsoil and is available to the summer cereal when
it is required. The N-level fluctuates between 60 and 110 kg N/ha,
depending on the cultivation goal, the quality of the soil, the previ-
ous crop and the crop management.

For winter rye, winter barley and triticale, the strategies for
ENTEC®-fertilization are similar to those for winter wheat.
only the level of N-fertilization and the size of the individual
doses have to be tailored to the needs of these varieties of
cereals. The timing of the N-doses, taking into consideration
the development stages of the plants, is the same. on soils
with sufficient water capacity and yield expectations exceed-
ing 80 dt/ha, the N-volume should be applied in two doses.
on lighter soils it is possible to work with a more extensive
fertilization strategy. Here the single dose of 140 – 160 kg N
(in the form of ENTEC®)/ha has proven successful. Fertiliza-
tion should be carried out at a later point in time, 2 – 3 weeks
after the start of vegetation.

The growth of rapeseed commences very early in the
spring. It can be rapid, depending on the temperatures.
With fertilization it is necessary to ensure that at the start
of vegetation enough nitrogen is offered to support this
development. With conventional fertilizers the nitrogen-
fertilization is split for rapeseed. The first dose is applied at
the start of growth. After about 2 – 3 weeks a second dose
is applied during elongation growth.
ENTEC® simplifies the application of fertilizer
to rapeseed:
Fertilizer in one dose at the start of growth.
Ensures the supply of nitrogen and sulphur with
one dose.
Persistent unfavourable weather conditions do
not affect further supply.
The target yield is ensured by a single dose.
Time becomes available for other work due to
the fact that no second dose is needed.
