Sand = Dirt

There's already oxygen, why would we need a gas for nitrogen, they're basically the same

we do not need nitrogen at all

Both of these are useless

NTGN will only be made if the LN2 has a tmp of 1 (made by condensing NTGN, tmp also carries over to NICE) so that saves that use nitrogen based elements don't break. Also NTGN could act as an easier to use RFRG maybe? NTGN combined with HYGN at 500 degrees will make AMNI (ammonia), which is toxic to stickmen and when added to DSTW makes WATR (really don't need the ammonia as dstw is converted to watr when touching watr but this is the only way to make fertilizer without adding another element, tell me if yall want another element).

AMNI will also break back down into NTGN and HYGN at 550 degrees, so you need to be careful about that.

DIRT would still act like sand, and it would absorb at most 10 pixels of WATR (saved in the life value like SPNG) and help PLNT grow a bit faster by travelling through the plant (you can just steal the lith charge spread code here, the value is stored in life or tmp3) and going to an area that is exposed to air. Tell me if you want anything else in this

I feel like these are a good idea that can be used for nitrogen how about a grill type thing using nitrogen (if what I think nitrogen is is correct I'm not going to look it up) also dirt would have different properties than sand such as being able to get wet it could make mud  or it when it's wet it can act like a spongy substance causing some powders to slowly fall through it or slowly fall down using like a weight or something 

An easier way to make gaseous nitrogen feasible in tpt is to rename LN2 into coolant and NICE into solid coolant; there are many abbreviations proposed for both elements.
