- dragontamer 5y agoAnd the next most significant macronutrient is nitrogen/potassium. Aka: typical fertilizer.
- Ma8ee 5y agoThe right plants catches nitrogen from the air. Fungus and microorganisms make minerals, like potassium, available from sand and rocks. This works great until someone destroys the soil by killing all microorganisms with pesticides or fertilisers. Forests are very good at producing a lot of biomass without help fertilisers, even when a lot of trees are "harvested".

- riffraff 5y agolikewise, took me years to internalize that when you're losing weight, you're breathing and pissing most of it: you burn C+H+O compounds, and expel CO2 and H20.
- Cthulhu_ 5y agoYeah I mean, there's barely any solid residue when you burn fuel in your car when you think about it. There's some (carbon), but most is converted to CO2 and H2O.
