Pine bark mulch

duajones · February 23, 2011

I have a friend that just tilled for his spring plant out. There was a pretty good layer of pine bark mulch left from his fall garden. I have read that this will tie up available nitrogen. What can he do to counter this?

Shorter term: Add additional slow-feed N.

Longer term: Till in winter cover crops.

The wood will convert to humus eventually so is valuable for soilbuilding.

It depends on the texture, too. The larger pine bark "chips" will take awhile to breakdown. I regularly use pine bark "fines" as a soil amendment to great effect. As ireilly said, adding nitrogen will help overcome any short term issues.

If its all bark I wouldn't worry about a N tie up at all. Its the actual hardwood that will tie up N. I use bark fines as a main ingredient in my container soils with no N problems. JMT

I am making potting mix out of pine bark. The bark breaks down slowly; it should be good for his soil.
