Total organic carbon influences many soil characteristics including colour, nutrient holding capacity (cation and anion exchange capacity), nutrient turnover and stability, which in turn influence water relations, aeration and workability.
In soils with high clay content the contribution to cation exchange from the organic fraction is generally small compared to that from clay. In sandier soils the relative contribution of the organic fraction is higher because there is less clay, even though the amount of total organic carbon present may be similar or less to that in clays.
By providing a food source for micro-organisms, organic carbon can help improve soil stability by micro-organisms binding soil particles together into aggregates or ‘peds’. Bacteria excretions, root exudates, fungal hyphae and plant roots can all contribute to better soil structure.
Moist, hot and well-aerated conditions favour rapid decay of organic additions. If the rate of organic matter addition is greater than the rate of decomposition, the organic fraction in a soil will increase Conversely, if the rate at which organic matter is added to soil is lower than the decomposition rate, the organic fraction will decline.
At a steady state level, the rate of addition is equal to the rate of decomposition. Large organic additions can temporarily increase the organic fraction in a soil, but unless additions are maintained, the soil will revert to its steady state equilibrium, which is usually low.
