Engineering HSC and IIT-JEE Mains an

advance videos. Hello students today will
[10]
be studying chapter Miceobes in human
[13]
welfare in that will be studying today
[15]
about biofertilizers when I say
[18]
biofertilizers bio means organic or
[21]
naturally available and fertilizers and
[24]
nothing but manuals which enrich the
[27]
nutrient nutrition content of a soil or
[30]
nutritive value of a soil now there are
[33]
various chemical fertilizers available
[34]
today we will be studying about
[37]
fertilizers which are present organic or
[41]
which are naturally available.
[45]
Biofertilizers Biofertilizers are easily
[49]
available that who knows cause any
[51]
pollution to the soil but what are this
[54]
bio fertilizers made up of bio
[55]
fertilizers are basically made up of
[57]
organisms it could be simple organisms
[61]
like earth moon which enrich the soil
[64]
quality when a bone is added into soil
[68]
it passes to the field and burrows the
[71]
soil or the field and in this process it
[74]
mixes all the nutrients of the soil it
[76]
enriches the soil quantity by the
[79]
biological activity microorganisms
[81]
increase the fertility or the
[83]
effectivity of the soil when you compare
[86]
with chemical fertilizers biofertilizers
[88]
do not cause any harm to the soil an
[90]
example of National bio fertilizers
[93]
which are available on microbial cases
[96]
would be sino bacteria one fungi and
[100]
different kinds of bacteria sino
[102]
bacteria is nothing but blue green agate
[104]
now this blue-green alga is naturally
[106]
present inside rice fields and in rice
[109]
fields it helps to transport nitrogen
[111]
while the rice crop is growing we all
[114]
know that rice crops means a lot of
[116]
water and nitrogen fixation in rice
[118]
lands is done by cyanobacteria while
[122]
adding nutrients this biofertilizers
[125]
increase other phytonutrients like
[128]
nitrogen phosphorus in the soil and the
[131]
crop grows very effectively
[133]
biofertilizers are the cheap source of
[135]
nitrogen fixing and well as phosphorus
[138]
fish fixing ailments available so let us
[141]
see how by for let's help
[144]
[Applause]
[209]
my offer glazes organisms that help to
[213]
enrich soil quantity and increase soil
[216]
fertility by their biological activity
[219]
it means organisms help the plant to
[221]
increase in phosphorus nitrogen content
[224]
naturally without causing any damage to
[227]
the crop of the field a dundas
[229]
biofertilizers main source of
[232]
biofertilizers are bacterium it could be
[235]
symbiotic or symbolic like a nabina not
[239]
stock etc fungi as well as cyanobacteria
[308]
this organisms president biofertilizers
[311]
causes nutritional content of soil to
[315]
increase rapidly this could be nitrogen
[318]
phosphorus and sulfur without causing
[321]
any damage to the crops or without
[323]
having any side effects on crop or crop
[326]
cycle they are cheap source of
[329]
fertilizer secondly they are much
[332]
effective than chemical fertilizers like
[334]
urea which cause a lot of damage to crop
[338]
cause pollution and even it is expensive
[341]
in this part of the chapter we have
[343]
studied how biofertilizers have helped
[346]
humankind and what are the great aspects
[349]
of bio fertilizer as compared to
[351]
chemical fertilizer I hope you all have
[354]
understood till early about this topic
[358]
thank you
