CO2 TO BOOST FARMING OF CROPS

Petroleum companies are converting themselves into energy

companies to become more sustainable. Repsol is one of

these and has several projects going on or completed with

successful results [10]. One completed project is carbon

fertilization, called ‘CO2 Funnels’, developed at Repsol’s

Technology Centre and tested in several greenhouses

installed in the Industrial Complex of Puertollano (near

Ciudad Real). The project has shown that carbon fertilization

improves the yield of non-food plant species, which will then

be used as biomass to produce bioenergy, because these

plants grow faster thanks to higher doses of CO

CO2 en cultivos”, Repsol blog. (http://blogs.repsol.com/web/innovacion/

Respected arvind sir thank you so much for your help. Trees are physiologically large and often need lots of space. Please tell me the plants with short stature. Thanking you sir

Respected Rene aga sir, the words like carbon fertilization and Co2 funnels interested me so o will dig some deep into these topics. Thank you sir

I suggest you to contact the Repsol Technology Centre for more information via the attached link.

SIr how about nerium species is it best Co2 fixer ?

I'm not an expert in botanics, but it seems me that you could find an answer in this book available online:
