In general crop rotation reduces the green house gasses, for example corn rotate with soyabean or wheat is found to be very effective in reducing GHG.

Sinciere thanks for answers

Hello Sir, yes, we can find out which crop is tolerant to major air pollutants by some biochemical parameters. These crop can definitely help to reduce the CHG emissions. I have done tolerant plants analysis to combat against air pollutants. Your question made me think to analyse the crop tolerance. Thank you Sir.

Thanks Dr.Asawari, discussion in relation to scientific expertise reavels many more things in future.
