What is total soil carbon (TSC)?Group of answer choicesSum of SOC and SICLiming materialCarbonatesSoil reaction

Total Soil Carbon (TSC) refers to the sum of Soil Organic Carbon (SOC) and Soil Inorganic Carbon (SIC). It represents the total amount of carbon stored in the soil, including both organic and inorganic forms.

Here's a step-by-step breakdown:

1. Soil Organic Carbon (SOC): This is the carbon that is part of organic compounds. It comes from living organisms and plant material in different stages of decomposition.

2. Soil Inorganic Carbon (SIC): This is the carbon that is part of inorganic compounds. It is primarily present as carbonates in the soil.

3. Total Soil Carbon (TSC): This is the sum of SOC and SIC. It represents the total carbon content of the soil.

So, the correct answer to your question is "Sum of SOC and SIC".
