Mark,
When I need to spread small amounts of fertilizer over my 1.5 acres, I
mix it with sand and use a Whirlybird Broadcast Spreader to spread it.
Without the sand, I put too much on part of the garden and nothing on the
rest.
You mentioned that one of your ingredients was a powder while the rest
was granules. That can be problematic because by the time the fertilizer
spreader moves even 10', all of the powder can settle to the bottom and the
end of the row doesn't get any of it. I mix my fertilizer in a cement mixer
and if the powdered fertilizer doesn't become saturated throughout in the
first try, I use the whirlybird to spread the powder and the broadcast
spreader for the granules. This means two fertilizer spreading passes down
every row. I need the exercise anyway.
My soil recommendations for peaches indicated I needed 65 lbs. of N; 100
lbs. of phosphate; 95 lbs. of potash; 2.5 lbs. of zinc; 1 lb. of boron per
acre.
