How much fertiliser can a plant tolerate?
« on: 25/05/2008 09:35:33 »
Jay Patel  asked the Naked Scientists:

I am a avid student that has to do a independent study project for my environmental science club and I was wondering if you could help me out with a question i had in mind.

Is there a certain limit of fertilizer a plant such as grass can take in and would it cell membrane take in too much fertilizer (overflow/breach) when it's just trying to get a little bit to supply itself?

A environmentally concerned student,
Jay Patel

What do you think?

You can definitely poison plants by overfeeding them.

This is particularly the case with plants that have evolved to grow in very nutrient-poor environments and therefore have very efficient scavenging systems to obtain the trace elements they require. If you come along and fertilise one of those it can be a case of death by excess...
