Agriculture
appears to be the second biggest economic sector releasing greenhouse gasses according
to the 2014 IPCC report. Although there is a perception that organic farming is
more environmentally friendly, many studies claim otherwise and individual
farming techniques influence the emissions more.
In this
study we concentrated on vegetable production in Palas Plain, Kayseri, Turkey. We
made surveys with 14 organic and 18 conventional vegetable producers in 2016.
In this
paper we evaluated the direct and indirect greenhouse emission differences on
conventional and organic farming practices only due to tractor and fertilizer
use.
The amount
of energy per hectare of agricultural land was 468 GJ/ha (SE:
75.78) for organic
farming and 365 GJ/ha (SE: 60.91) for conventional farming due to tractor using. There was no
significant difference between the energy consumed by tractor use (p= 0.55, n=
32) and the amount of fertilizer used (p= 0.087,
n= 32). CO2 equivalent values of emissions from organic and
conventional areas were 97 tons CO2-eq/ha (SE:15.70) and 76 tons CO2-eq/ha
(SE:12.66), respectively.
There was
no difference between the organic and conventional farming on the carbon
emissions levels (p=0.55, n=32) but the difference was on individual practices
including fertilizer type and the amount of time tractor used.
