The document discusses the differences between modern and old farming methods. In olden times, farming relied more on manual labor and green manures rather than machines and chemical fertilizers. Seeds were also of lower quality. Now, agriculture utilizes many machines, produces higher yields through improved techniques, and relies more on chemical pesticides, fertilizers, and higher-quality seeds. However, modern farming also causes more pollution and environmental degradation through extensive machine and chemical use.

2.  Agriculture and farming have been the main
occupation of people all over the world throughout
the years in History. But in the olden times, the
farming systems and processes were completely
different from the modern times. Technology were
not improved and machines were not utilized much
in the olden times. But to fulfill the needs of modern
world with a huge population, rapid changes have
occurred.
 So in this presentation, we are going to discuss about
the differences in the modern farming methods in
comparison with old methods.

13.  In olden type of agriculture, less chemical
fertilizers were used; instead the green manures
were used much. But now-a-days more chemical
pesticides, weedicides, fertilizers etc. are used.
 In the olden times, Agriculture hugely depended
on human labour and lacked farming techniques.
But as we can see now, agriculture now uses a
lots of machines in almost all works.
 Bad quality seeds were used in farming in the
olden days but now much better quality seeds
are used for resistance to disease or high yield.

14. Due to the improvements of techniques and
ideas in modern agriculture, now the
agricultural yield is very high in the fields. Even
in small land holdings, much produce of crops
can be done due to improved agricultural
methods.
Less human labour is needed in the modern
agriculture.
The use of machines enable the agricultural
processes to be done in a large part of land or in
huge areas of cropland.

15.  As more crops are produced, including surplus
crops, cash crops can be grown by the farmers
which brings extra profit for them as well as will
avail us with other products like jute, tea, coffee
etc.
 The modern pesticides, weedicides, insecticides,
etc. protect the crops from diseases and let them
live longer for right yield. But we have to keep
check on the amount of chemical fertilizers used
in fields.

16.  More and more pollution is occurring in soil, water,
air due to the use of extensive machines that emit
harmful smoke and leave poisonous residues.
 The fossil fuels are also getting used up more quickly
as mostly all machines use up a lot of fuels all over
the world.
 The crops are getting poisoned due to excessive use of
chemical fertilizers that are harmful to us.
 The nature is depleting gradually due to the extensive
use of man made and chemical components.
