炭同灰

請問用炭同用灰係咪可以中和泥土ph 值?

如果點檀香粒o既灰....有無呢個功用? 用得嗎?

找張pH紙來試下就知啦

如果土壤係鹼性呢？

用白灰得唔得呀？

最有效係石灰~~
檀香粒o既灰有毒O架咩?

I use universal pH paper too.
It is more accurate.

I burn all sort of plant to get ash and charcoal.
After that, I put them into the soil.

Hopefully, it will help.

Where do you buy the universal pH paper?

Buy it from chemical store. you want?
But they have a scale that need to go with it to use. Otherwise I can give you some.
