Need to understand that till date is there any research has been carried out for soil science of organic farming. What are the soil chemistry, what are the microbial interaction in organic farming soil?
Organic agriculture is a production system that sustains the health of the soil and people......Science to benefit the shared environment and promote fair relationships and a good quality life for all involved. Healthy soils are key to biodiversity , food security and a fundamental role in fighting climate change. Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. The key attribute is improving soil fertility by maintaining and building a fertile living soil through the application frequent organic matter inputs in the form of green manures, compost and farmyard manure and by adapting cover crops and crop rotations and inter-cropping.

yes organic farming its key to reduce Gas emission change
pls read my Msc thesis about organic farming in arid region
Currently, only 1.2% of the world agricultural land is under organic farming. However, because of increasing consumer preference for organic products, organic farming has been increasing steadily. India has 9th largest agricultural land area (1.5 M ha) used for organic farming by in excess of 800,000 producers. The largest land mass used for organic farming is in Australia (27 M ha), much of which is under extensive grassland.
There is plenty of literature available on organic farming soil quality, mostly comparison between soils from conventional farming versus organic farming. One example is Y. Ikemura and Manoj K. Shukla, Journal of Organic Systems – Vol.4 No.1, 2009.
Many studies have also shown, nitrate leaching losses have been lower from organic farming compared to conventional systems. Studies have also found, generally while crop/animal product yields have been lower in the organic systems, it has been offset by the higher product price fetched by the organic systems. Interestingly, it has been found organic systems also emit lower greenhouse gases (GHGs).
To date, organic farming studies have shown, highly improved physical, chemical and biological properties of soils which have resulted in better water holding capacity, soil fertility and lower environmental impacts.
A review on organic farming could help to highlight the above findings (K.S. Lee et al. / Journal of Environmental Management 162 (2015). I suggest you search for more open access papers.
