RE: Calcium Nitrate Benefits?
Nutrient percentages don't vary by bag weight, only the total nutrient
pounds (i.e., a cup of fertilizer from a 25 pound bag of 10-10-10 is
identical to a cup from a 50 pound bag of 10-10-10).

Wayne: I seem to remember that calcium nitrate was 15.5 % nitrogen
and 19%
calcium but don't quote me on that! as for the 32-0-0 I believe it
all
hinges on the bag weight and all we are looking at is the percentage
of
nitrogen vs. the bag weight?
to calculate percentages of fertilizer in a given bag.
i.e.. 10-10-10 50 lb bag would be 50X.10=5 (50lbs X fertilizer
number =
nutrient percentage.
there-fore a 50lb bag of 10-10-10 will have 5% nitrogen 5%
phosphorus and 5%
potassium
or 5 lbs of nitrogen 5 lbs of phosphorus and 5 lbs of potassium
what do you think?

Lets see,my error?.....it says (12) foot circle...it doesn't say
(12) foot
diameter circle. Judging by my notes from last year,as a second
year
newbie,
I interpreted "(12) foot circle" as a circle with a six foot
radius...6
feet
to the left and six feet to the right,making in the end a circle
about 12
feet ....perhaps my interpretation was wrong..........but it says
"12 foot
circle." In any case,Wayne, it may be a waste of nitrogen . Perhaps
it was
the calcium he was after...maybe,as a beginner it was more
important to get
the calcium up than wasting the nitrogen.
I also have written in my notes that the calcium nitrate I used
was
32-0-0....this would indicate twice as much as Wayne's calculations
!
I would definitely go with Waynes warning Gang.....but it didn't
hurt me
at
all,probably due to my sandy soil.....G

G,
Calcium Nitrate is 15% Nitrogen. I was assuming a 12 foot
diameter circle
when I came up with the 108 Square feet where he applied the 10
pounds. Its
not so much the wasting of nitrogen, that amount of nitrogen is not
good for
a pumpkin plant. Creates an excessive jungle of foliage and could
create
fruit set problems. Sometimes on a CaNO3 label you may see a 4th
number
expressing the % available calcium. I couldn't find my label in the
file
cabinet, but I think the Calcium level is around 20%. Not sure what
the 32
number is. Sandy soil will leach out the nitrogen quicker, but that
is still
a big jolt.
