N: 198 - 339
P2O5: 68 - 114
K2O:734 - 1268
CaO: 165 - 273
MgO: 92 - 155
Their suggestion for fertilization is (kg/ha):
N = 190 (22%)
P2O5 = 91 (10%)
K2O = 454 (52%)
CaO = 67 (8%)
MgO = 76 (9%)
8% and 9% are pretty far from 0,3% and 0,15%... that's why I'm asking. Maybe I'm missing something (this is not at all my expertise). If so, please explain (in a frieldy tone please).
I'm using Fruit Fuel, bought from Richard a few years back. So my question is releated to Fruit fuel. |
Thank you for being a loyal Fruit Fuel user.
And thank you for the clarification as Banana Fuel (this what you were asking in your post #40) manufactured by a different company and Fruit Fuel manufactured by "Grow More" are two different products.
Do you have a concern with the Fruit Fuel? Are your plants not performing well?
This is what to look for:
Magnesium is contained in Chlorophyll and is vital to the green shade of a plant and its capacity to produce nourishment from sunlight. It is needed for sugar development, but it is also needed for the uptake of other nutrient, especially phosphorus. A lack of magnesium would result in mottled yellowing leaves, they may turn dark and die.
It is my understanding that too much magnesium does not directly affect plant production, but it can cause deficiencies in other nutrients like calcium or potassium causing limited fruit production or poor root development.
Calcium is needed for new root development and new suckers. It also assembles cell walls. An insufficiency of calcium can be seen if new leaves emerge deformed or start to shrivel at their tips.
Forgive me, I am just reading your link on my lunch break on a limited sized phone screen, but Table 25 shows Calcium percentage range 0.4% to 1.0%,
Magnesium percentage rate 0.2% to 0.36%. Both are close to the 0.3% Calcium and 0.15% Magnesium in the Fruit Fuel.
I have seen the Haifa studies before and they are referring to field grown commercial banana plantations under (almost) ideal growing conditions and not to growing "a" plant in a pot or plants I grow as a hobby gardener in a marginal climate.
Having said that, I highly recommend any gardener to do a soil analysis to take the guess work out of the game.
If you look at Table 23 of your link, it shows some significant differences in soil analysis between the Caribbean, Costa Rica, Martinique and Australia.
