Save Soil
Podcast Description
A podcast dedicated to exploring the silent crisis threatening the foundation of our existence: soil degradation. In each episode, we delve into the problems facing our soils around the world and, most importantly, the practical solutions that we can all implement.
From erosion and desertification to the loss of nutrients and biodiversity, our conversations with experts, farmers, and activists reveal the urgency to act now. You'll discover why the Save Soil movement is crucial for global food security, the climate crisis, and the health of our ecosystems.
But this isn't just a podcast about problems: it's a call to action. We share regenerative techniques, effective policies, and lifestyle changes that can transform the health of our soils. You'll learn practical solutions that you can implement in your garden, community, or through your power as a consumer and citizen.
Join us on this essential journey to understand and protect our planet's most precious and undervalued resource. Because when we save the soil, we save our future.

Summary:
– The episode explains that saline soils arise when irrigation leaves salts in the soil, reducing root water uptake and harming soil structure, chemistry, and biology. Salt makes the “living sponge” (the soil) harder, with fewer pores, leading to wilting and lower productivity.
– Diagnosis and immediates: measure soil electrical conductivity (EC), look for surface crusts, and review irrigation/drainage history. Midday wilting suggests salinity issues. Start by checking drainage and use data to plan leaching or crop-management actions.
– Practical steps to restore saline soils (in order):
1) Improve drainage to prevent salts from moving toward roots and to wash them away.
2) Leach salts carefully with controlled irrigation (drip or micro-sprinklers) without wasting water or nutrients.
3) Add organic matter (compost, manure, cover crops) to improve soil structure and moisture retention; consider dedicating part of the plot to cover crops.
4) Use selective amendments when needed (e.g., gypsum in sodic soils) only after proper diagnosis.
5) Choose salt-tolerant crops and rotate with legumes to boost organic matter and soil biology.
6) Keep the soil covered year-round (mulch or cover crops) to reduce evaporation and salt rise.
7) Protect soil biodiversity with beneficial microbes and inoculants; avoid excessive saline fertilizers.
– Recovery timeline: soil recovery is gradual, taking months or years depending on salinity levels and water availability; consistent drainage, water management, and organic matter buildup are key.
– Framing the process as a project: start with diagnosis, followed by a drainage plan, an irrigation/amendment plan, small-plot testing, and scaling based on results.
– Engagement: listener prompts about which step to start this week; encouragement to share plans and results.
– Additional insights: salinity also harms soil microbiology; modest compost can help reverse compaction; cover crops can boost biodiversity; if soil is viewed as a bank, organic matter compounds over time.
– Quick fact: salt management depends on the balance between salinity and sodicity; gypsum helps displace sodium only after proper diagnosis.
– Goal and next steps: provide concrete tools for evaluation and improvement, with a proposed 60-day plan for the next episode; invites deeper study of efficient irrigation, amendments, and cover-crop rotations.
