Re: CULT:Micronutrients--was Boron

<< Quick looks into a few plant physiology books show that Boron (an element
 with the symbol B) is required by plants as a micronutrient.  It is usually
 found in plants at a concentration of about 5-75 parts per million dry
 weight.  Most plants get enough boron from the soil; boron deficiency is
 said to be rare. >>

Thank you. That was interesting. Especially that bit about loss of apical
dominance.

Anyone know anything micronutrient deficiencies to which irises of whatever
sort are  particularly sensitive, of any? And what about excess rain in this
connection?
