Decompose during the year multiplied by the amount of fresh residues added (A), or gains = (f)(A). For purposes during one year (the SOM change) can be represented as If you follow the same cropping and residue or follows: SOM change = gains – losses manure addition pattern for a long time, a steady-state situation usually develops in which gains and losses [equation 1] are the same and SOM change = 0. Losses consist of the percentage of organic matter that’s mineralized, or If gains are greater than losses, organic matter accumulates and the SOM change is positive.
