Re: Soil Ammendment Questions

Jordan,
The heavy hitters told me to either disperse 3-5 lbs. of Calcium Nitrate or
5 lbs. of bloodmeal within a 6-10 ft. circle around the plant. I presume
that means the radius would be 6-10 ft. Therefore the formula is
A=(pi)r(squared)
A=3.1416 x 10 squared; A= 3.1416 x 100=314.16 or A=3.1416 x 6=113
So spread either of these between 113 to 314 sq.ft. around the transplant
area. I use 5 # per 100 sq.ft. of blood meal or 3# of calcium nitrate per
100 sq. ft. Blood meal is slow release and shouldn't burn the plant at the
rates I've recommended.I was a little off suggesting 100 sq.ft. as the area
but one heavy hitter I know does the 5 lbs. over a 100 sq.ft. area but be
careful as his soil may be different and N requirements may be way
different. The earlier dierection would probably be safer, although you do
need some N. The reason they suggest that 5#/1000 sq. ft. is that they mean
5 lbs. of pure N. If you used urea which is very strong at 46-0-0 you would
need like 10# of it over a 1000 sq.ft. area since it is 46% N. Bloodmeal is
12-0-0 so you would need about 4x as much as the urea so about 40 lbs. per
1000 sq. ft. or about 4 lbs. per 100 sq.ft. around the transplant area. That
area is where you really need it when the plant starts to run from the 4
leaf stage to about an 8 ft. plant. N leaches quickly from the soil as P and
K don't. If you spread it over the whole patch it may leach some before the
plant really gets to use it and also you don't want much N after the 8 ft
vining stage. I personally don't spread it past the 10' radius around the
transplant.  I cant remember what % N there is in Ca Nitrate.    Hope this
helps.  Don
