Re: Soil Ammendment Questions
List
Most of you are awair of the N.P.K recommendations but for those of you that don't here is a reminder when they say 5 lbs of nitrogen etc, they are referring to ACTUAL nitrogen the N.P.K on a fertilizer label is based on a 100 lb bag so to make this easy lets use the big numbers. if you had a 50 lb bag of urea 46-0-0 you would have 23 lbs of actual nitrogen in that bag so you would apply almost twice the amount of actual weight in fertalizer to gain the ACTUAL amount of fertalizer. here is where it gets tricky if you had a 100 lb bag of 50-50-50 if there was such a thing you would have only 13.75-13.75-13.75 of fertalizer since in a 100 lb bag you can not have 150 lbs of fertalizer in 100 lb sack. i am pretty sure i am correct on my numbers but it has been a few years since i got out of college.. take care all and have a wonderful 2007 season

Do you mean 1000 sqft? The recommendations said 5 lbs per 1000, not 100.
Just want to make sure. 10 times the needed N would be a problem (not saying
you are wrong, just that 10x would be bad). Vigoro has some 12-0-0
bloodmeal, and bonemeal 1-11-0, would these be fine for that? As for the two
weeks, I suppose I could just put in in most of the garden (except where I
am starting the plants) since I want to plant next weekend. Should they be
tilled in, or is spreading and watering enough?
Thanks
