Modern industrial fertilisers are made from fossil hydrocarbons. In future we can't use that. But, although I am prejudiced in favour of #organic agriculture, I'd be interested to know whether it would be possible to synthesise fertiliser from widely available resources without using fossil hydrocarbon.
Anyone got any pointers?

Spatially distributed complex #organic matter detected in an ancient river valley in #Jezero crater, #Mars: #Raman spectrometer onboard the #Perseverance rover, we report the heterogeneous distribution of organic carbon within mudstones located in an ancient river valley on Mars. Measurements of two mudstones show hundreds of organic detections, making this the most robust organic detection in Jezero crater thus far, and, to our knowledge, the only detection of macromolecular carbon on a natural rock surface on Mars."

I did find some phone pics of the process. The most interesting steps are missing, but it's better than nothing.

Brass cast little sculpture of a wood cube showing tunnels carved by a woodworm. Of course the tree was already firewood when I found it, I only cut it into a rough cube. And the woodworm was long gone: Wherever you are, I hope you're OK, it was nice making this collab with you.
