I think its actually N that's locked up.Apparently mag is locked with low calcium.
I presume both locked, one to the other.I think its actually N that's locked up.
According to how I understand it from @Gee64 , without adequate Ca, the Mg binds up the N and locks it up. So, it looks like an N deficiency, when in reality it is Ca. Once the Ca is supplied, the binding releases and a flood of N can give a temporary excess.I presume both locked, one to the other.
Thank you! That's a very understandable explanation Gee, so it might not be necessary to slurry test and give it a dose of calcium first and watch what happens in general?Its actually possible for both to get locked.
Think the platters of food. Theres a platter with all cations on it, including magnesium. Ready for the plant to eat it. Thats the food. Ready to go.
Theres also soil structure that relies on calcium to restrict magnesium's electrical stickiness, so when cal gets low in the soil magnesium gets stickier and attracts and bonds to things. It likes nitrogen the best.
(Excess magnesium is said to be able to bind 1 for 1 mag to nitro. I don't know if its true but I have read it more than once.)
So if its bonded to nitrogen a nitrogen deficiency appears. Nitrogen is called Locked Out.
Now back to the platter of food.
The plant wants the magnesium but in order for a magnesium to come off, another, or a different cation of the same charge must hop onto the platter. If the platter can't recognize new magnesium because it has nitrogen attached to it, then there may be no recognizable magnesium for the Cation Exchange to supply to the plant so...
In some situations adding calcium to the soil relaxes magnesiums grip unlocking nitrogen, the nitrogen deficiency goes away PLUS magnesium is now recognizable to the Cation Exchange and food flows again, including magnesium.
Or you could be low on nitrogen, or magnesium, or calcium.
Start with calcium.
Usually you add a nitro fert like fish or a tea, and it doesn't work so your thinking wtf? The nitrogen is there, just locked.
If adding calcium works it unlocks that nitrogen plus all atmospheric nitrogen so quite often adding cal actually causes nitrogen toxicity, but short lived. 1 or 2 sets of leaves get clawed. Then it corrects and grows good.
Thats why your Dad always limed the lawn. Limestone is calcium. Makes grass greener.
Four guaranteed beasts is what you'll make!
Yes I will! Try my best!Four guaranteed beasts is what you'll make!
That's how locked up my brain can get Azi. I will get this!I think its actually N that's locked up.
Yes it's got 6 or 8 grows in it and has been amended each time. It's full of what makes the world a fertile place! I just need to find the balance there. @Gee has been a patient tutor to a pretty thick student. I always did have a problem trusting my tools until I got to a tipping point of knowledge. Electrical theory(including tube theory) was one that took a while to apply. This is another little bump I'll get over.Otter, didn't you say you were growing in well used soil plus amendment? Your aggrie, do they do a test for you?
Thanks GEE!Its actually possible for both to get locked.

I don't know much about Rosemary but I always start with calcium.Thank you! That's a very understandable explanation Gee, so it might not be necessary to slurry test and give it a dose of calcium first and watch what happens in general?
Otter, didn't you say you were growing in well used soil plus amendment? Your aggrie, do they do a test for you?
Gee, my Rosemary is yellow and so I have been putting her through wet and dry cycles to see if she was droughting or drowning, and this morning I gave her some fish fert. Do you think that might fix it, or should I add a shot of calcium?
Its not a guarantee that its actually calcium causing it. But there is a really good reason that CalMg works so well. It can fix cal,mag,iron,or nitrogen def's.Yes I will! Try my best!

I would think it's a good idea to rebalance it with a soil test at this time. They haven't gotten back to me with what test I should order yet.
Thanks GEE!
Never synthetics far as I know. Things are starting to make sense. I'm going to try cal/mag in the SIP. These 4 I don't know yet. I've always fixed it with epsom once or twice and they have a real good showing. I'm less than a week from having calcium leached into vinegar from oyster shell flour. I could maybe use that for a drench add?Its not a guarantee that its actually calcium causing it. But there is a really good reason that CalMg works so well.

The problem is you never know which def you really had.
High mag, for most growers never happens, but mag needs to be ratioed with calcium properly, so low calcium can easily become a mag or nitro problem.
If your soil is really dusty and fine when dry then mag is low. If its crusty its high. But possibly only high or low on the ratio, so sometimes adding the one that isn't the problem fixes the ratio.
Thats for organics tho, if you are using synthetics then I have no idea.
Hopefully that makes sense lol. Watch the soil when its dry. Can you easily stick a finger in all the way?
I would start with spraying it to test. Calcium drenching works well but just a bit to strong can really hurt the plants.Never synthetics far as I know. Things are starting to make sense.

This mix I tried some malted barley and insect frass in it. It was the first time I can say it became hard crusty in the barrel. There were thick smelly white streaks through the barrel too that may have disappeared over time after I re mixed it. Now that I'm thinking, this was a tester soil for those inputs. They didn't work out! The barrel lost inches of soil loft during cooking.Wood chips or bark mulch mixed into the global mix, or too many dried leaves, cause it most often.
Sawdust is a bad one too. Its an excellent carbon, but if it clumps up it takes forever to cook.
So make a calcium vinegar/water mix and spray the soil surface? Keep it ? ppm?I would start with spraying it to test. Calcium drenching works well but just a bit to strong can really hurt the plants.
Quite often low cal is the culprit tho. Do you use adequate amounts of dolomite when you rebuild? Does adding nitrogen fix the deficit or does it only start to fix it and the deficit returns quickly?
If its returning quickly chances are its getting locked. Calcium will fix that but it WILL immediately make available all the extra nitro you added trying to fix the deficiency so add calcium slowly to release excess nitro not all at once.
If you add calcium and see some dark green leaf clawing, the calcium is working.
Thats good info! Go look back at exactly what you did and how that strayed from your usual inputs.This mix I tried some malted barley and insect frass in it.

Talk to Azi about this one for ppm's and stuff. He has been trying it for a week or so. Check his progress to find a starting point.So make a calcium vinegar/water mix and spray the soil surface? Keep it ? ppm?
