Aged Pine bark Fines as soil ammendment...
I have access to bulk "aged" pine bark "fines". While they are not technically composted, They have been aged for 1 year + in piles & kept moist & turned. It's also described as readily rewettable.
sizes of material are as follows:
5-8% greater than 1/2" (but less than 5/8"
25-31% less than 1/2"
64-71% less than 1/4"
Moisture content 25%
Considering using it to add organic matter to my sandy soil by incorporating it into the soil, also possibly as a top dressing/mulch, also possibly as a mulch on my centipede lawn.
Would I need to be concerned about it tying up nitrogen since it has been aged for at least a year? How about it Lowering my already low 5.9PH w/ 7.75 buffer ph?
I've misplaced my notes but seem to remember it being low in nitrogen, very low in phosporous, and relatively high in potassium. My soil currently is low in potassium & high in phosphorous so was thinking this might be the ticket for me.
Any more thoughts on this stuff? Anyone with any experience?
