Ok, how about this?
Off the top of my head I'd guess that the order things would disolve would be K, N, P; but I'd be completely unwilling to wager any of my own money on that.
I say that because most potassium salts are highly soluble (then there are a few that are completely insoluble), you could engineer something that is slow release for it but off the top of my head I can't think of a good one.
Some common forms of nitrogent are ammonium nitrate and urea, both highly soluble.
"super phosphate" I have often found is moderately soluble in water and takes a while to disolve.

Say, is there going to be some Ridley Scott movie about this fruit?

People land on a planet and find that a giant intelligent kumquat may have seeded life on different planets?

'Its fruits are yellow-colored and are known as "Gold Apple". They have a strong fragrant smell and have medicinal value.'

Looks like someone needs to update wikipedia....

'It is so good I once carried a fruit around in my pocket, and now and then I would pick it up and smell it, and each time praise it. The flavour is like the fragrance.'

That sounds pretty impressive (well- "the flavor is the fragrance").  I'm not sure I get why one takes a fruit out of ones pocket and praises it, unless you're trying to make an empty seat on public transportation.

I'm becoming interested in it already just by reading the name "Cinnamon Apple". I like cinnamon apple. 

I think the person who gave it that common name was seriously deranged... possibly high on nutmeg.

The few times I've had it I didn't taste cinnamon or apple notes....

Can someone describe the flavor? (or better yet send me a fruit )

hahaha!

Now I found the picture I was looking for to enter!  It's a baby pic of my first guanabana fruit.
It was lost in my computer in a random folder!

Oh, well.  At least I can still choose it as my wall paper when guanabanas are in season near me again.

You're already ready for the next photo contest... nice shot BTW

This rugged little tree has performed phenomenally for me.

Its about 12 yrs old, and was given to me by a good friend in FL.

I found out that this is a special hybrid, but it has seeds? and apparently my tree came true from seed?  Maybe I'm mistaken?  But I've tasted fruits from a tree labeled as Procimequat, and mine are the same, and the person who gave me the tree, planted the seed (so it's not grafted or a cutting).

The tree seems resistant to greening, and bugs!  Maybe because it's a whacky hybrid, or because it's to short to be noticed!

The fruits can be eaten skin and all, and they taste like.........hmmmm......

celery, lemon, and orange.

I've really grown to like them, but I haven't found too many kumquats that I will eat skin and all.  These fruits are of a different nature, and would probably be good as a garnish, or candied, or cooked somehow. 

The trees flower and fruit for a good portion of the year. 

Anyone else growing this one?

here is a fabulous link I found about this plant...makes me happy to have one.

and here are a few pics of my little old tree, in 3 gal pot.

Procimequat, the genetic remix?  Is the genome spoonerized?

Surprised you don't like kumquats out of hand, I always enjoy them (well the common ones).

Some Syzygizium outside Buttatingit

your picture is beautiful, to the max.

but I have trouble believing this is a true syzigium.

Thanks...  my stomach was angrily growling since there were no fully developed fruits on it!

An inexpensive handheld tester that claims to test nitrate levels is probably not terribly accurate.  Its better than nothing but I imagine it would have lots of false positives (readings higher than actual) as well as negatives.  It probably uses an Ion Selective Electrode (ISE) if you are lucky.  Such sensors are better than a lot of other quick/cheap alternatives but they can be fooled and their results can drift over time.  Also just sticking it into a fruit or vegetable seems like poor sample preparation.

Okay i should not write poisonous but i mean "safe" fruit.

The reason why i want to test it myself is that nobody can be trusted in this. If you were the guy who has to check meat-farms in Holland for used hormones then you better wear a bulletproof vest that's how the meat-business works there.

In Thailand there is no inspection as far as we know and if there is then they might be corrupt or just sleeping during worktime. I would not trust on that and that is also for chinese fruits.

I heard about some fluid that you can soak your bought vegy's in and it will become very slimy when it takes the chemicals out of the vegy's. Maybe we can use something like that?

We always peel our fruits but it would be great if we can be sure that our fruit is healthy by doing a small test. Tests are also not 100% trustfull (see Lance Armstrong) but at least we can get some info then.

Anyway thanks for the reply's.

Well you can do your own tests but currently to do so you need a lot of expensive lab equipment, proper training, and good procedures.

Hopefully someday "lab-on-a-chip" will realize its full potential and people will be able to cheaply buy detectors.  Even when this does finally happen (probably 10-20 years from now) sample preparation might be somewhat of an issue, and you'll only be testing for the substances that chip "knows" about.

In the meantime your best bet would be making some kind of "consumers union", collecting small fees from the members and pooling that money to do lab tests.  You could even send the samples to some lab in Japan if you are worried about the growers/distributors bribing or intimidating the lab staff in Thailand.

You also mentioned a substance for removing contaminants from fruits and vegetables.  I see things sold in this country for such a purpose and am highly skeptical about them.  The one you describe sounds even more suspicious to me.  I suspect it is no better than water at removing harmful substances and imagine that the change in viscosity (going from standard fluid to slimy) is just a gimmick to make you think it is doing something useful.

Your best bet for chemical decontamination is washing in water and then peeling.  Numerous things aren't easily dissolved by water BUT you don't want to wash things you eat with other solvents (because then you'd probably end up eating some solvent residues)

If a flight is transiting the USA and you are not leaving the airport, do you need to have USDA permits for your plants?

I can't see why you'd need a permit for transiting.
If you leave the airport you would need a permit...

This is for LAX: All passengers including transfers (to Puerto Rico, Dominican Republic, wherever) must retrieve their luggage before reloading the luggage for the transfer flight. I came back to LA from a recent trip and this was the announcement. Apparently some foreign countries, maybe Philippines, told passengers that their luggage would be automatically transferred. I don't remember whether they had to go through the full customs and agricultural inspections.

Having to pickup and recheck luggage is a big nuisance but it happens occasionally in various airports.  If you have to go through full inspections you would know about it because you have to fill out forms, make statements,.... which is more involved than picking up and rechecking.

I cringe when I have seen the speculative and over application of pesticides in Thailand.At least here it is regulated and monitored . You can't test for it yourself.Poisonous does imply toxic fruit and there are a few native ones around here that are toxic.

I think some Thai growers are actually very careful and methodical.  I saw groves of wax jambu where they bagged the fruit (a labor intensive way of making sure they don't become grub mush).  I'd worry more about the stuff imported from China where food safety is pretty poor (melamine in formula for babies, oil skimmed from the sewer sold as cooking oil,...).
