The figure seen for young trees is 12 N, plus smaller quantities of P and K.
Hence why we take the lawn fertiliser to 1/3 strength into moist soil [ watered once the night before ]
once a week.
Thanks
@Andrew Robson,
Will test 1/4 Lawn Fertiliser next year.
Our use of 12 N is to help the trees withstand our Dry season and the the two months where we can hit
low 90's deg.F for half an hour to ten minutes.
.
Been doing this for many years. Works, growth is slow and bitter [ insects won't chew save for 4" grasshoppers
and leaf cutter ants trying to survive. ] and the leaves stay a deep healthy green.
The sun also keeps the leaves small so no need to depend on defoliation.
Our compost is a blend of materials with weeds for micro nutrients so the fertiliser stays basic.
Main ingredient gives 2 N and reads as rabbit manure.
Try getting Dyna anything down here, even Miracle Gro is rare. You see the lawn fertiliser you buy several
containers.
Not so the liquid stuff, so old it's reacting on itself and forming solids.
Got heavy showers last week, and yup the tamarinds responded and so did the leaf cutter ants.
Got servings of citrus peel with chemical x. Nests are dead now. Waiting for more arrivals from the
neighbour's yards.
Rains are coming and temps will drop to 80's and cloud cover, so little or no fertiliser.
By Autumn, the rains will hit 9" for August and around October so no fertiliser as the moisture in
the air, bright light and extra water will keep things growing.
Found out compost holds 20 times it's weight in water [ or fertiliser in solution ] and some of the
trees use an inorganic that can hold moisture, but will only break in the soil after maybe thousands of
years. So fertilising is really only for 5 months.
We did test an osmocote type [ it was recommended again to us by Michael ] but gave it up and may
test it again on a few trees.
For faster growth we use the grow trough [ ground grow ] and the over sized boxes for refinement.
So you don't really need much fertiliser.
We seldom hit 90's for any length of time so growth is mostly constant.
Oil cake meals are around 6N and lower P and K.
Good Day
Anthony
