@will I only recently started working with the ammonium sulfate the last couple of months. I have not used it extensively but utilizing it as I see issues. I initially started looking into it as a means of increasing alkaloid production . I started thinking that since Kratom is so closely related to the coffee plant what is the coffee industry to change caffeine production in the plant. Caffeine is an alkaloid. Just thinking out loud here
I’ve been sprinkling a little blood meal for some extra nitrogen, but it doesn’t have quite that much. But I also do nitrogen rich liquid fertilizer at least twice a week.
My interior leaves are slowly yellowing and dropping, but the new growth looks very green and healthy. You guys think that’s lack of nitrogen, or normal for growing in our climate?
Great question and discussion. i haven't treated or fed mine with anything and most of the new growth on the trees I've looked at so far are putting out nice deep green growth. No doubt they all need something good to eat. I have some bone meal left, how's the blood meal working out?
I have a half thought thru theory that during the winter the soil pH increases due to reduced rain water and replacing it well mineral ridden well water. Then in the summer the rain water begins to neutralize whatever salts built up etc. Unleashing these beasts we know of as trees.
Heyey rk when did you start working with the nitrate?? Whatever is going on I hope it continues.
Great report! Yes, the ammonium sulfate is slightly acidifying the soil, lowering the pH, and allowing more minerals to be absorbed. This can relieve leaf conditions such as low iron, magnesium, manganese, and boron absorption. The pH of the water really matters. The new leaves do look happy.
we've all had to deal with yellowing leaves. Well I finally found a solution. You can see the yellow leaves with green veins and then the new growth which is the lovely deep green we all desire. This was accomplished by my new secret weapon, ammonium sulfate. Which has an NPK number of 21-0-0 this is a 7ft tree and I sprinkled 3 tablespoons ammonium sulfate around it halfway between the trunk and the drip line. As you can see the new growth now looks like it's supposed to. I'm in the middle of trying this on some javanika and I expect the same results
