Yard-waste compost, vermicompost, biochar, gypsum to amend caliche/sandy soils
Key Questions
How do biochar and compost improve caliche or sandy soils?
Biochar and yard-waste compost increase organic matter, enhance microbial activity, and improve water infiltration in challenging soils.
What soil amendments are recommended for container tomatoes?
Container tomatoes benefit from compost, sand, perlite mixes, and 12-inch drip placement to support intensive planting and root health.
How does mulch contribute to soil health during heat waves?
Mulch conserves moisture, moderates soil temperature, and supports microbiome activity aligned with EC and bicarbonate testing.
CA farms biochar/agave + Sicily mulch yields/Schipanski microbiomes align with EC/bicarb tests and Rio Puerco no-till. New: Container tomato specifics and intensive planting/mulch caveats; soil health for OM/infiltration; quince NV soil prep (compost/sand/perlite) + 12in drip. Aligns with heat-prep mulch emphasis.
