The
application to the volley of fertilizers (for example super phosphates)
it should be made before the first leveling trail or between the
first one and the second for a good incorporation to the floor of
the fertilizer.
SPECIAL
CARES IN THE PREPARATION OF THE FLOOR
The
actions for the control of the erosions, as the construction of
terraces and curved of level, they should be executed after the
leveling of the floor.
The
application of the lime should be made between 60 and 90 days before
the sowing so that the calcareous one has time of reactivating the
floor.
OBSERVATION
It
is very important to wait that the incorporate vegetable material
to the floor for the plow rots before the sowing. Otherwise, the
seeds will die by reason of the effects of the fermentation of this
material.
SOWING
The
best sowing time is when the rains happen with more frequency (of
April to October in Venezuela). In burnt areas, therefore, the sowing
should be made on the ashes, this means, before the first rains
are presented.
Be
which the chosen method was, the sowing should facilitate the uniform
distribution of the seeds for the whole area that will be formed.
In the case of sowing in it lines or in furrows, the spacing between
them should be the best possible.
A frequent
cause of failures is the sowing of an insufficient quantity of seeds.
The good regulation of the sowing equipment is a form of guaranteeing
that the certain quantity of seeds is sowed. That quantity called
RATE OF SOW varies of agreement with the material type and the lot
of the seed.

So
much the purchase of seeds, as the one calculates of the appropriate
rate of sowing they should be based on the Cultural Value (% of
VC) of the seed to be sowed.
That
value is of the analyses of the seeds in the laboratory and it represents
the percentage of viable pure seeds contained in the lot of seeds
(to see illustration about Cultural Value)
The
seeds should be covered by the floor after their distribution in
the area. The bury excessive of the seeds it is also a frequent
cause of failure in the pastures formation.
Small
seeds as those of the varieties Tanzania, Mombasa, Guinea, Andropogon
and Setaria, they should be buried to not but of 2 centimeters deep,
while those of Brachiarias (brizantha, decumbes and humidicola)
to not but of 4 centimeters (1 and half times the size of the seeds).
In
sows to the volley, made, for examples with a machine fertilizing
or airplane, the seeds are deposited on the surface of the floor
and they need to be buried then. That can be made in the following
way:

sows to the volley, made, for examples with a machine fertilizing

way:
- With

- With
slight, closed trail, this is, regulated so that the disks they
are parallel to the direction of the movement of the tractor,
so that they are not buried the seeds a lot. (Except for panicuns).
- With
a passing of the tires of the tractor for the surface.
- An
enough quantity to tramp the land.
SPECIAL
CARES IN THE SOW
Much
equipment used for the sow (mainly machines to fertilize lime) they
don't allow to regulate inferior quantities to 7 or 8 kilos of seeds
for hectare. If was necessary to sow smaller quantities that these,
sand, phosphoric rock, dry and milled manure, sawdust or it cracked
of rice, rot to be blended with the seeds to increase the volume
to be sowed. Some fertilizers like the chloride of potassium, urea
or ammonium sulfate (nitrogenous fertilizers) they should not be
blended with the seeds, because they interfere directly with their
germination causing their death. On the other hand, the phosphatize
fertilizers (simple or granulated super-phosphate) they rot to be
blended provided the sow occurs in the same day in that the mixture
was prepared.
The
use of the stick compactor immediately after the distribution of
the seeds, it favors their contact with the floor, positioned in
the appropriate depth facilitating a quick and homogeneous birth
of the tiny plants.
Therefore,
the sow should not be made in case it rains after the distribution
of the seeds (because the rain for if alone it promotes the one
buried of most of the seeds), neither in very loamy floors, especially
when they are humid.
During
the sow, the shake of the sowing can be that the seeds are added
and separate (straw, pure seed and fertilizer). To avoid this, we
advise not to fill the box of seeds of the sowing a lot. This will
make that the tractor driver makes reinstatement several times of
seeds, promoting with this the uniformity of the mixture.
ESTIMATING
THE OPPORTUNITIES OF THE SUCCESS
For
a good beginning of the formation of a stable it is necessary that
they are obtained, as minimum 20 born tiny plants (and well distributed)
for square meter in the case of the varieties of the generate Brachiaria;
while 40 tiny plants are necessary in the case of the varieties
of the generate Panicum maximum (Tanzania, Mombasa), Setaria and
Andorpogon.
FIRST
SHEPHERDING
The
first shepherding, when it is made in a correct way, it guarantees
the success of a very established formation. It should be made then
that the plants are grown and covering the whole sowed area. In
this case it is better to use slight, young animals, to hardly make
it blunts of the plants.
In
this phase, if heavy animals were used, the plants could be pulled
up during the shepherding.
If
the first shepherding was made a lot but it takes, many plants will
die by reason of the competition between them.
That
increases the empty spaces in the pasture diminishing the production
of the pasture and it facilitates the growth of harmful herbs.
Starting
from the first shepherding, as the plants are developed, the pasture
normally should be used.
