Not all the matter in farming fields come from fertilizer. A lot of it comes from CO2 in the air, which will eventually go into some plant that we can eat. Also, all those ways that matter is lost, therefore not being 100% efficient doesn’t make matter disappear. Burning turns it into CO2 -> it will reach a plant. Excrements going into water streams -> plants will pick them up, or ocean wildlife will pick them up. Buried corpses -> microbes and plants will pick them up. The only way to “lose” matter is for it to leave the atmosphere into space or to be buried so deep that no life can reach it.
The atmosphere loses matter at a rate that is (presumably) not affected by human actions.
Matter buried too deep is compensated by matter coming out from volcanic eruptions.
As long as the earth’s core is hot enough for volcanic activity and the sun doesn’t run out of fuel, the cycle keeps going.

Thanks for letting me know you suck at chemistry. I appreciate you.
I appreciate your comment, such good feedback. I don’t know what I said that hurt you but I’m sorry.
