Pollution and Soil Fertility
Intro
CI
Stubble Burning
Green Revolution increased
greatly rice and wheat production
simultaneously
increased stubble
post-harvest
However
popular combined
harvesting technique
was not efficacious
machines
left behind one-foot-tall stalks
Prompted
stubble burning
as low-cost and speedy solution
available to farmers
due to limited time period of 20-25 days
btw harvesting crops and sowing another
MB
BP/GE/IS
Impact of Environment
releases harmful gases

nitrogen oxide and
carbon monoxide
into atmosphere
worsen
making lungs weaker and
people more susceptible to disease
impact
recovering from COVID infection
Vast smoke blankets
across the Indo-gangetic plain
and numerous neighbouring states
Exposes
million of people
to air pollution
Impact on soil fertility
destroy organic fertilizers
and reduces ground water levels
threatens food security

Air (Prevention and Control of Pollution) Act of 1981
Way Ahead
Setting up
Custom Hiring Centres
facilitate farmers
removing stubble
by providing machinery on rent
Application
happy seeders and super SMS machines
improve agricultural productivity
by 10% to 15%
allowing
soil to become more fertile
PUSA Decomposer
help paddy straw
to decompose
at faster rate than usual
farmers
shred the straw
spray solution
containing fungai strains
and mix it with soil
for decomposition
Potential to reduce
air pollution and
increase soil fertility
