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 microplastics in agricultural soil: tiny plastic fragments from degraded plastics, textile fibers, and farming materials, arriving also via contaminated irrigation water and compost or manure. They’re not inert and can accumulate in topsoil or spread deeper.
– Effects on the soil and harvest: microplastics alter soil structure, porosity, water retention, and air flow, which affects nutrient availability and the activity of beneficial soil microbes. This can lead to less stable soil, more water stress, and sometimes lower or less uniform yields.
– How microplastics interact with the field: some stay in the topsoil for years, while others penetrate deeper and interact with soil water and microbiota. They can release chemical additives and attract contaminants like heavy metals, influencing fungi, nutrient uptake, and overall plant health.
– Two main impact pathways: (1) physical/structural changes to soil aggregation and water retention; (2) biochemical changes due to additives and contaminants affecting microbiota and nutrient availability. Readers are encouraged to reflect on their own field observations regarding germination and growth.
– Considerations for exposure: heavy use of plastic mulch leads to fragmentation and persistent microplastics, which can affect harvest quality, texture, and plant health.
– Practical steps to gain control: simple surface soil sampling to estimate plastics; assess the origin of agricultural plastics (e.g., disposable mulches or nets); prioritize waste management and consider reusable mulch options; promote soil-building practices such as cover crops, crop rotation, and adding high-quality organic matter.
– Prevention and ongoing management: opt for more durable mulches, better management of sludges and compost to avoid contaminants, and promote soil biodiversity to help break down plastics and trap fewer-mobile particles.
– Additional context: mentions resources on desertification (sav esou1.org) and presents Sadhguru’s view of soil as a living organism, advocating less tillage, more crop diversity, cover crops, and organic matter to nourish soil life.
– Three-phase action plan:
– Phase 1 – Diagnosis: root-zone soil sampling.
– Phase 2 – Reduce inputs: identify and replace key plastic-entry points on the farm.
– Phase 3 – Soil strengthening: use cover crops and certified compost to support microbial life.
– Yield considerations: there is no universal answer; effects depend on plastic load, crop type, and soil conditions. Proper practices can minimize negative effects and maintain a viable harvest.
– Monitoring guidance: use a simple log of rainfall, temperature, waste management, and visible plant stress; correlate data with productivity to gauge microplastic impact and adjust practices.
– Call to action: commit to small, sustainable changes in soil management to reduce plastic load and improve soil health; healthy soil supports harvest and food security.
– Closing invitation: subscribe, share, or provide feedback; contact details are given for further discussion.
