Dear senoirs friends,
We know that carbon sequestrated as soil organic and inorganic . Several fancy literature reported that IC is high than OC. The organic forms usually labile and available to plants, microbes. SOC maintains soil health and improves fertility status. For example cotton stalks mixed with surface soil (plough) and incorporated to soil. It has both organic and inorganic carbon. Organic forms utilized in further intensive cultivation . However, In semiarid tropics and arid regions non utilized are inorganic carbon, which accumulates in subsoil and also they react with calcium and turns to CaCO3 . It is referred as Pedogenic (Secondary) carbonate. While another few literature suggested that this process cause land degradation. kindly clarify me with your valuable suggestions and inputs.
I would request you to refer to the attached pdf, which addresses this particular issue in details for Indian SAT soils. With best wishes-
Suggested articles were quite helpful for me. Some unanswered personal questions were answered
Organic carbon play a positive role in crop production and restrict the soil degradation. Inorganic carbon play +ev role up to a certain extent but later it may be a cause soil degradation.
