Chicken Sh1t pH

Ive experimenting with some new nutrients. Ive read in a few places about people using chicken manure - so i got some and gave it a try. To start it seemed OK. I will keep using it on the lawn and vegetable beds.

BUT. A magnolia i was rescuing died suddenly midway through opening its flowers. I was not pleased.

I added some pH test drops to rain water. The London rainwater is strongly acidic. This yellow color is the most acidic color that the kit measures indicating 6.0 or less.

I then dropped a small piece of chicken manure pellet in and observed.

As the manure pellet dissolved it made the solution strongly alkaline. The light wasn't good - but the pH is towards the high end of the scale. So in the region of 7.6 which is a substantial swing.

The lesson learnt is that i must test new additives before i put them on to avoid unexpected results.

For species that like alkaline conditions this is fine. There are plenty of trees down south grow in the chalk. I would recommend avoiding this for acid lovers like pines and magnolias / azaleas.
