Gardening Tips: [MittleiderMethodGardening] NPK Blend

Wow! Thanks for the quick reply :) I am anticipating that I will also
have to add 100lbs of magnesium sulfate and the requisite quantity of trace elements?

Also I have a little more than half an acre divided up into 132 soil grow-beds. Would I be correct in thinking that the quantity of fertilizer I calculated would be able to feed all 132 beds for 5 weeks (5.6 times)?

I have 18" by 30' grow beds, and I am a bit confused with the planting densities for tomatoes... is it 2 rows of 41 plants spaced at 8" or just one row that is used?

Thank you again for your assistance. Rick

Rick & Group:

You only plant one row per bed of all vertically-grown crops. And you need to be diligent and consistent in your pruning and removing suckers on the tomato plants at 8" apart.

I figure you need the following additional ingredients:
Magnesium sulfate - - - - - - - 105#
Boron - - - - - - - - - - - - - 6# 3 ounces
Zinc - - - - - - - - - - - - - - 6# 3 ounces
Manganese - - - - - - - - - - - 3# 8 ounces
Iron - - - - - - - - - - - - - - 1# 3 ounces
Copper - - - - - - - - - - - - - 1# 3 ounces
Molybdenum - - - - - - - - - - - 9 ounces
Granular gypsum or lime - - - - - 11#

You have 750# of fertilizer, which will feed 132 beds 5.7 times.

It appears that you are really beginning to "get" the fertilizing. Congratulations.

You DO what you are planning, and you will have a tremendously successful garden.

can't very well take part of the phosphate out of the 13-13-21 that's
as close as you can get it. And that will work fine.
