[edit] Added stuff

Added stuff because there was just a ton of stuff on the rest of wikipedia that needed to be linked to. Perhaps this needs a more complex description of the symptoms of each, but if they need it, they'll get it eventually. 128.101.70.246 16:26, 14 November 2005 (UTC)lotusduck

[edit] Nickel

My biology textbook says Nickel is also an essential micronutrient. If anyone knows more about this maybe it should be added. —Preceding unsigned comment added by 128.255.202.132 (talk) 00:37, December 13, 2005 (UTC)

I'll put something on about nickel. It's involved in nitrogen metabolism according to my biology textbook (by Kent). Feel free to delete or challenge! Ahezhara 20:11, 8 February 2007 (UTC)

[edit] look

this is a great page, lots of good information although its not all consistent...

e.g. the minor nutrients list has chlorine although the 'plant uses for essential nutrients' does not describe why it is necessary. also, the latter list decribes why nickel is essential but nickel is not presently listed under the minor nutrients category.

so, yeah. im not going to change anything because i wouldn't have a clue, just thought i should put this all out there...

someone vandalized sulfur and calcium!!!!

[edit] Mnemonic... things

Why are there two mnemonic things on this same page? It seems to me that only one would be necessary.206.74.172.254 23:47, 26 November 2006 (UTC)

How strange. Which one do we want to keep? They're both slightly different Ahezhara 20:11, 8 February 2007 (UTC)

This really should be merged with the "micronutrients" article. —Preceding unsigned comment added by 24.8.154.100 (talk) 22:23, 27 October 2007 (UTC)

[edit] Number of essential plant nutrients, is it 16?

I want to know the number of essential plant nutrient with the year of discovery and scientest. —Preceding unsigned comment added by 59.176.104.198 (talk) 11:27, May 28, 2007 (UTC)

[edit] Macronutrients

I think alternative names for nutrients should be given major nutrients = macronutrients, further divided into primary (NPK) and secondary macronutrients. minor nutrients = micronutrients

also more information about mechanisms of nutrient uptake...cation exchange is mentioned, but doesn't anion exchange take place too? also passive uptake of nutrients through transpiration of water? Tugela tony 11:23, 30 May 2007 (UTC)

Very valid point. Someone correct it 59.183.143.98 18:35, 24 August 2007 (UTC)

I like having this topic on a separate page. It would be good to note somewhere, for those of us less science-oriented, that several supplements have boron (types) in them and whether too much can be taken in a day's time. thanks for all you do. —Preceding unsigned comment added by 70.43.134.76 (talk) 15:52, 26 November 2007 (UTC)

[edit] Vandalism

This page has been vandalised, so can someone please revert it back to the unvandalised version?Don Black 18:22, 28 October 2007 (UTC)

[edit] Concentrations

The ppm concentrations for the nutrients appear to be average concentrations in plants, but are not explained. Nor is a reference given. Drbillellis (talk) 16:42, 16 March 2008 (UTC)

[edit] Tables to be incorporated

There are two nice tables at Plant physiology#Constituent elements that should probably be incorporated into this article. -- HiEv 18:29, 27 April 2008 (UTC)
