Detailed explanation-1: -Sphagnum peat moss, hypnum peat moss, and reed and sedge peat moss are three types of peat in horticultural classification. Sphagnum peat moss is the most desirable and popular type, as it has higher moisture-holding capacity and does not break down as rapidly as other types of peat.
Detailed explanation-2: -Sphagnum moss is perhaps the most desirable form of organic matter for the preparation of growing media. Drainage and aeration are improved in heavier soils while moisture and nutrient retention are increased in lighter soils.
Detailed explanation-3: -If there are large amounts of straw or sawdust, nitrogen availability to plants may be lowered by increasing the C/N ratio. High carbon relative to nitrogen (greater than 25 /1) will tie up nitrogen.
