(Fwd) Re: Re: CULT: mulch (was TB: Mariah)

Oops, I didn't recognize that the article was sent to me only until yawl mentioned not 
receiving it.  After not finding it in the archives, I looked at the message again, so 
here it is.  The 'To' and 'Subject' lines are as John sent them.  This is a forward.  I 
hope the table stays in line.

Now yawl can sleep in peace with visions of sugarplums and not wonder if you 
missed a 'rare' iris message.

The arrticle appeared in Vol 209 pg 52  - April '73 (thank you to the
online index)

I scanned it, fixed up the formatting, and copied it below.

Just FYI, the scanning, optical character recognition and reformatting
took about a 20 minutes. The time could be shortened by tuning the
OCR, but things like charts do not capture well. This should give you
some idea of what it would take to get all the historical text on
line.

There is a reference to a footnote that does not appear in the
bulletin.


B. Y. MORRISON RESEARCH PROJECT

Bed Preparation for Bearded Iris

The second of the B. Y. Morrison Research Projects, done at
Mississippi State University, is off the press, and the report,
prepared by J. H. Perry and C. O. Box, sheds some light on a cultural
procedure. The research was sponsored jointly by the American Iris
Society and by Region 24 of the American Iris Society.

Materials and Methods

"Uniform rhizomes of Iris germanica PINNACLE were used for this study,
which was begun in the fall of 1969. The outdoor planting areas were
established to simulate slightly elevated home garden flower beds.
Three feet by six feet frame of 1" x 6" rough lumber were built on a
leveled area. A Kaufman sandy loam soil was then put in the frames and
allowed to settle. After it was settled, the top 2- to 4-inch layer
was replaced with the following materials as treatments: 2 inches of
sand; 4 inches of sand; 4 inches of sawdust; and 4 inches of perlite
and soil (mixed 1 part to 4 parts, respectively). For example, where
the treatment was two inches of sand, an equal amount of soil was
removed from the frame and there the 2-inch layer of sand was added.
In this manner, the level of the media was consistent throughout the
design plat. After the treatments were made, the rhizomes were planted
in the various media. The treatments were compared to a Control of
Kaufman sandy loam soil. There were 30 rhizomes per treatment in the
test. Data was recorded at the time of flowering in the spring of
1971."
