Garden Math
I just put 5# of 12-0-0 blood meal out. I -think- that this means that I
applied (5 pounds of blood meal) * (.12 percent Nitrogen) = .6 pounds of actual nitrogen. Is this correct or am I doing the math wrong? My last chemistry lab was 34 years ago so I am a little rusty. :-) Bill -- http://cannaday.us (genealogy) http://organic-earth.com (organic gardening) Uptimes below for the machines that created / host these sites. 01:00:00 up 3 days, 8:44, 2 users, load average: 0.04, 0.08, 0.08 00:55:00 up 104 days, 4:07, 1 user, load average: 1.63, 1.78, 1.80 |

Is this correct or am I doing the math wrong? My last chemistry lab was 34 years ago so I am a little rusty. :-) You did the math right (5 * .12 = 0.6) but just for the sake of clarity the 12 in 12-0-0 is 12 percent, not .12 percent. 12 percent is 12/100 or 0.12. So, either (5lb blood meal) * (.12 N) = (0.6lb N) or (5lb blood meal) * (12% N) = (0.6lb N) -- Henry |
