Anyone using urea for blueberries?

riverman1March 17, 2014

I just had a ph test done on my small patch of blueberries and found them to be on the low side, between 3.9 and 4.3. For this reason I don't want to use ammonium sulfate and want to try the Urea form. Anyone else doing this?

I haven't used urea but would in your situation. It is recommended for low pH soils. When applied water in. It will volitalize if left on surface.

Human urea is a concentrated form of nitrogen so if you use too much you'll get lots of leaf and not much berry.

Hi riverman,it's been awhile.I hope things are going well.Still in the Tri-cities?
Ever try the fish/kelp/molasses mix that Blueberry Croft Farm or Backyard Berry Plants uses?I remember talking about that.
Also,I thought your soil test fee was around $10.I'm not sure,but if it was,I'd like to get one done.Who can I contact? Thanks,Brady

Hi Brady, I'm in Walla Walla. I use Unibest Inc. to do my soil tests and ph tests. They use resin technology, its cutting edge stuff, check em out. I think a soil test with them is about $30. I haven't been using the fish kelp mix lately. My ph is too low so trying to watch it this summer, no ammonia and no sulfur. I applied a small amount of urea to each of the plants yesterday.
