Lecture 14 : Vermicompost Production Technology (Contd.)


So, welcome to the lecture 14 that is a vermi
that is a same continuing as a vermi vermi compost production technology. So, so we will
dis here we will discuss about the harvesting of Vermicompost after judging the maturity.
Then how can harvest vermicompost and separate the earthworms from the vermicompost.
And forward by the drying to ah have a proper moisture content in the vermicompost and finally,
ah packaging and storing. Ah for the ah harvesting ah and earth and the earthworms separations.
For the harvesting, is generally done manually ah by using a shovels and and and load loaded
on the hand trolley. Ah the separation of earthworms vermicompost is generally done
manually or by mechanical process. So, now you have the harvesting also you ah can go
for the ah mechanical processes so that the there are different type of vermicompost beds.
So, after the maturity so it can be ah plate beds weevil beds also. This can be unloaded
and after that it can move for the separations of the earthworms either the manually ah mechanical
process, then you go for the drying. So, whole process so now we are coming up the automations
in the vermicomposting process. So, that how how a using the ah hi tech ah technological
approach ah we can monitor the ah the the quality parameters in composting process.
And this every all the process can be automated as a mechanical means as a mechanical process.
So, that there will be less inventions of the a human power or man power.
Ah you can say the the manual process by the separation of the earthworm. So, the heap
method by this a vermicompost ah after ah harvest is heap is a gather heaped in a dome
shape in a open space or on cement floors ah under the bright sun lights, at the height
at about 2 to 3 feet’s. So, what happens if you say make a heap them up the in a in a
open space or the over the over the sun, under the sun the worms move to a lower layer or
the worms are light sensitive. Thus first letting harvest of compost from the upper
surface this process is repeated may be 3 or 4 times and all the adult worms migrate
to the base of the heap and can be separated, but this process is time consuming.
As we ah ah low put the vermi compost then a ah under the sun. And heap it as a dome
shape as a as a dome shapes and as the earth worms moves to the bottom layers. Then we
can take away the you can take out the upper layers of the vermi compost by step by step.
And finally, the as the earthworm migrates to the the bottom layers. Those earthworms
can be separated by manually sieving operations. Ah Mechanical process for this earthworm separations.
So, this earthworm separated by a sieving, using a wire net of 2 to ah 3 millimeter size.
In separation process the earthworms remains above the net and the vermicompost fall falls
below the floors and these are collected. The sieving unit may vary in size and its
operational. the sieving frame including the stand and net can be placed either on the
ah simple plat form or the sieving load platform or rum by motorized shaker.
So, ah so there are different type, either you come for the manual sieving that is as
the ah the labors can do by size of the 2 to 3 millimeters heap size or ah mechanically
ah a also will be showing in video as you are seeing. So, how this sieving operation
can be done by the mechanical vibration of the sieving machines.Where the earthworms
is separated on a on one location one points and the vermicompost are collected in another
points. And these are the harvesting ah of heap method
. So, ah as we make a doom steps of the heaps and under the sun’s. So, they with the lights
the earthworms they migrate to the deeper layers. So, by making the heap we can collect
the vermi compost by step by step from the upper layers and the bottom layers can be
used for the manual sieving or the sieving process.
And this also drying will discuss what you can make the you can put the vermicompost
is a plastic sheets. The plastic sheets make a entire maintains of temperatures and can
be vermicompost can be spreads for drying I can go for the sun drying usually for the
air drying. So, this is separation process ah either you
can have the sieving methods. By sieve you can separate the earthworms or this is a mechanical
shaker. So, you put the vermicompost here, load is here, and by the motorized shakers
by shaking we can collect the the vermicompost at one points and the earthworms at the other
other point. And this is the drying cum ah sieving machine
ah so, here we have the ah dryers, where here the hot air blower is there, and the top there
is a sieving machines, this vermicompost loaded on the top. So, this can be a can be conveyor
belt it attach to the systems and the vermi compost is loaded on the through the conveyor
belt. It come to the top loadings. So, after that there is a shaker is there say mechanical
vibrations. So, through this shakers as a as a as a sheet
sieving machine and here the vermicompost falls downs. And this the earth worms their
collected in the on the other ends, while the vermicompost are collected at the at the
bottom of this machines. Here there is hot air blowers and we we provide the hot airs
. So, that the the at the same times the sieving separation from the earth earthworms and also
drying operation can be performed at at one go.
And finally, the vermicompost is collected and that this send for the bagging and this
is also [an/another] another dryers. So, you are the dry the sieving followed by the drying
drying. So, you have the hot air blow blower gives the drying also the sieving machine
is there where the earthworm is separated one points and the vermicompost dryers and
also collect collected. Drying and packaging so for ah ah marketing.
Ah It is packaged at a moisture container label ranging from 25 to 30 percents. Usually
go for the ah sun drying or may be the solar drying systems. So, you do not go for less
than 25 25 to 30 percent moisture content should me main maintained for the [panel]
compost final compost. If you decrease the moisture content in vermicompost live materials.
So, many microbes are presents in this a vermi compost unit the small earthen also maybe
there may present. So, to make them live ah so the moisture content
around 25 percent should be maintained and also higher moisture content is not required
because this is the moisture content convenient for the live of the vermi compost. Because
many micro organs are there ah many growth hormones and many many ah the growth regulators
are there are there in the. And also the body parts of the earthworms
they are. They are present in the ah vermi cocoons also ah may be there. So, they are
all the live things, need some moisture content around 25-30 percent is preferable for this
a final vermicompost. Conventionally ah after separation earthworms
vermicompost dryer in a natural process under this sun lights. Under cloudy whether particularly
during the rainy seasons open house drying becomes as a difficult. So, mechanical drying
as discussing mechanical drying. So, here has a spinning machines that is a 3 meter
in length and 1.5 meter in the width. So, spinning machine is there where the earth
worms and the vermi compost they are separated. So drying chamber then constant of thermo
settable blower and the proton furnace plate, that provide the hot airs ah. So, which can
make the at the on go a one go that is a drying of the compost.
So, we says there is a solar dress, drying systems can be used under the sunny ah sunny
weathers . So, after drying the vermicompost is backed immediately by manually or by the
mechanical device. And the bag should be stored under cool conditions in sets for the transportation.
And the ah and the used in the ah field. So, this are the sum of the drying process
in the video also next we have showing the video . How the ah separations can be done
from earthworm from the ah vermicompost either using the ah manual sieving or using the mechanical
say process by the same process by this mechanical vibrator and this sieving sieving machines.
And followed by the dryings how it can be ah dried in the over the by making the dome
shape ah. So, that the you can be piled together and the and the earthworm. Earthworms migrate
from the to the bottom layers from the top layer to bottom layers and the vermicompost
can be separate from the from the top by step by step. So, these are process will be ah
showing in the video and in few slides. Ah so now, will discuss about the harvesting
of the matured ah compost. So, in harvesting means initially you have to separate the earthworms.
So, from this compost then the put the compost for the drying ah because we will dry. So,
that the moisture content should be maintain around twenty five to thirty percent ah because
the earthworm contains many of the live organisms microbes are there. So, minimum moisture content
content 25 percent has to be maintained. Then go for the packaging of this vermicompost
ah. So, ah as you see here ah this is the matured
vermi compost and you can see the earthworms are there ah in this vermicompost. So, you
have some sieving technology ah by which we can separate the earth worm from the vermi
compost. Of course, the other methods you can make a heap. So, if you make a heaps the
earth worms are discard they do not like the light conditions they can go insides . So,
you can collect the earthworm from the upper layer slowly and slowly.
And the the leftover the ah vermi compost can be screened using the sieving methods.
So, now, they will be a loading this earthworm in the sweep. And will put will run this sweep
by sieving method we can separate the earthworm from this ah vermi compost So, for separation
of the earth worm in the vermi compost we are using the mechanical sieving methods
So, you can see this is the sieve so by vibrations. So, we can the earth the vermicompost can
be collected in one direction. This is the way of collecting vermicompost and the earthworms
can be collected in the other directions. So, now we will show you the load vermicompost
and run the machines. So, you can see ah the ah vermi compost in earthworms are separated.
So, you are now you are loading the vermi compost on this ac . So, by this vibration
you can see here. So, here we are collecting the ah the vermicompost.
This is a ah this is a good quality fine fine compost by the sieving methods. So, here you
can getting the the vermicompost like a [gran] granular shapes. And if you can see here the
here you are collecting collecting the waste materials the larger size particles and also
earthworms. This earth worms are also you can see this is the earth worms are getting
collected ah the . So, these are the earth worms . So, earth worms are collected ah in
one end and the vermicompost at the other end.
So, these are the waste material also we can we can again sieving the earth worm and the
later materials can be used for the composting process. So, this is the final vermi compost
you can see. So, this one we will moisture content is the more than 30 percent so we
will go for the drying . So, after drying ah one the moisture content comes 25 around
25 30 percent. You can go for the packaging of this vermi compost. So, this can be ah
good for drying, either the hot air dryers or this can be dried also ah by the over the
the floors where with the sun signs of sun signs, we can dry these and the moisture content
can be decrees to around 25 to 30 percent. So, this is the for the drying of the vermicompost.
So, we have here hot air dryer . So, hot air is blown for blown here the vermicompost can
be loaded on the top they have this sieves . So, vermi compost dropt here and you have
the hot air blower with hot air vermi compost can be dried.
A vermi compost are loaded on the top is the sieve is there and the from there vibrations.
So, vermi compost at dropt and with that there is a hot air blowers. So, with hot air the
vermi compost can be dried and collected at the bottom. So, after separations of earthworm
from the vermi compost, we can go for the hot air drying. Also we can go for the air
drying you can keep on the floors or on the plastic sheets. We can spread this and we
can allow this vermi compost to dry for certain period.
So, this is the final vermi compost as we have collected for for the separation of earthworm.
This can be spread on the plastic sheets or on the ah cemented floor also. So, after the
air drying when you observe there is a moisture contents are around 25 to 30 percent. Then
you can go for packaging of this vermi compost. After drying , so you can go for the packaging.
So, likewise the vermi compost can be packaged in a corporate goony bag because this is a
lie materials and the microbes are there they do have respirations. So, this is the you
can look with the final vermi compost after ah drying still the moisture content can be
brought around 25 – 30 percent and it can be packaged and this should be labeled also.
So, a means the label means the vermi compost the nutrient content has to be specified and
the producer also has be specified and amount of specially the major nutrients and macronutrients,
micronutrients. And if the vermi compost is prepared for specific crops like your potato
or any vegetables or any ah fuel grains rice or wheat that also to be specified on the
labels this vermi compost is suitable for the this type of the crops.
Now, ah we can show you a small demo. How we can use a vermi compost in vegetable crops?
So, we will go to the field ah How can prepare the fields? How can needs the vermi compost
in the ah before planting or the ah c d or before planting of seedling materials in the
man field? So, well so now we will be discussing about the applications of the vermi compost
or the use of the vermi compost in the ah crop productions either it can vegetables
or the cereal crops. So, this we are showing a integrated farming
system concepts, where we have a pond in pond we are growing fish fish culture. We have
also ah the crops we have the vegetable crops inside the inside the green house and also
we have the crops outside. the The concept of this one so there is a no waste in this
in this systems. So, output of one components is used as a input for the other components.
So, here we have the fish so you do use the freshwater ah in this pond. So, that fish
can grow and also the the water can be recycled back. And this water can be used for growing
ah vegetables or growing field crops ah So, this is a green house I what I feel that every
farm house should have a small greenhouse because this is used as a rain out shelters
or this can be used for the specially growing high value crops. If some farmer has to become
highly reminarity to have a higher higher income.
So, one small greenhouse can give you a throughout year vegetables as a oxygen vegetables or
the cash crops. We can growth the cash crops and can have a better income. So, ah now we
are we are going for the planting of the ah brinjal seedling. So, before planting you
have to prepare the ah soil well and this is a drew period systems. So, after preparing
the soil wells ah you have to make that particular spacing’s ; that means, the spacing between
the rows and spacing between plants in the same row.
So, as for the spacing at particular points so you have to ah put the vermi compost. And
this is this is the region pore system as I have made the regions and this is the pore
area and here the vermi compost are mixed at the point where the plant has to be grown
and this should be mixed well in the soil. So, in the soil and the vermi compost this
should be mixed together . So, likewise so the vermicompost and soils this should be
well mixed. After the proper mixing of the vermi compost in the soils. So, you can ah
go for the the planting of the seedlings. So, there is no need of applying vermi compost
throughout the field because the . So, this is a localized placement which as a banned
placement where the these are the place, where the crop has to be grown only those place
we mix the vermi compost. And we calculate the vermi compost as per the need of the crops.
And the well mixing they Then you can go for planting of this and the seedlings or you
have any cropping. You have the either the ah broccoli or you have the capsicums. This
seedlings can be planted here and this can be made slightly rich. So, that water should
not accumulate to the base of the stems. [FL] Made rich and of course, the deeper lines
we are putting the dripper lines here and as per the need the the dip dripper systems
can provide the water. And the water can be of also excess water can be drain to the pore
area. So, crop can be well protected ah from the excess water conditions.
So, of course, the drip area we are supplying water as per the need of the crops. So, this
is how when you go for the vermi compost applications, the field should prepared as for the need
of the crops we can apply vermi compost and using vermi compost we can grow ah vegetable
crops without any requirement of chemical fertilizers. And by the full amount of vermicompost
applications we can get the same yield as that the chemical fertilizers.
We can show you some of the crops we have grown like a cauliflowers in this summer seasons
like June, July. We are able to have coliflower productions using only vermi compost you can
see the growth of the crops. So, this is the coliflower we are able to grow ah inside this
greenhouse and using ah only vermicompost. In the month of because it was planted in
month of May, and now the crop has come to the ah floating stage.
So, by having this as a high value crops having this greenhouse. So, you can grow so high
value crops throughout the year and this can give you a better remuneration. So, that the
better profits to the farmers of a small farmer or marginal farmers. they can have such type
of the ah vegetable crops inside greenhouse and using only comp vermicompost you can have
you can have clergy or organic products as this has the high nutritional value as compared
to the chemical vermi the products from the chemical fertilizers.
So, it is free from pesticides or insecticides ah also it contains high amounts of this poly
secondary ah metabolites. So, you know the like cauliflower this has a higher glucose
lot contents, antioxidants, that is a good for the health of the crops. So, having the
ah greenhouse and doing the organic way by using vermicompost. The farmer can make the
more remuneration more profit can be self sustainable. It can meet is your own family
requirement at the same time he can sell the produce and can have a better income for his
own own living ok. Thank you very much.
