-Most chemical properties of soil organic matter result from the weak acid nature of humus.
-The CEC of organic matter, is due to the negative charges created as hydrogen (H+) is removed from weak acids during neutralization.
-When acids or bases are added to the soil, organic matter reduces or buffers the change in pH. Organic matter may provide nearly all of the CEC and pH buffering in soils low in clay or containing clays with low CEC.
-Organic matter releases plant nutrients as it is broken down in the soil.
