Who is still uncultured?
Most soil diversity is DNA-only.
Metagenomes keep finding lineages with no isolate. Functions are guessed from genes.
Climate models need better numbers on soil respiration and mycorrhizal carbon.
Open questions
How much carbon do soils store?
Budgets are being rewritten with new field methods.
Can we farm with fewer biocides?
Allies already work. Replacement is agronomy, not a home pathogen lab.
What do soil viruses do?
They likely regulate bacteria. Magnitudes are still debated.
How do cities rebuild soil life?
Compost, less compaction, less contamination.
The frontier is mapping jobs, not inventing a more dangerous spore.
