Why care about soil?
"The care of the earth is our most ancient and most worthy and, after all, our most pleasing responsibility. To cherish what remains of it, and to foster its renewal, is our only legitimate hope."
Ecosystem and landscape health
Biodiversity Support
Healthy soil fosters a diverse community of microorganisms, fungi, and insects, enhancing nutrient cycling and supporting various species.
Water Filtration
Soil acts as a natural filter, absorbing and purifying rainwater, preventing contaminants from entering groundwater and nearby water bodies.
Habitat Preservation
Soil is a vital habitat for flora and fauna, and its health is crucial for preserving biodiversity and ecological balance.
Erosion Prevention
Maintaining healthy soil structure through practices like cover cropping helps prevent soil erosion, ensuring the stability of ecosystems.
Aesthetic Value
Well-maintained soil contributes to the aesthetic appeal of landscapes, supporting recreational and cultural activities.
Health of our gardens and farms
Plant Health
Proper soil management practices promote optimal plant health, reducing susceptibility to diseases and pests. Healthy soil structure enhances root development and nutrient uptake, contributing to robust plant growth.
Contamination/Toxicity
Soil care includes measures to prevent contamination, ensuring that crops grown in the soil are free from harmful substances. Regular soil testing helps monitor and address potential toxic elements, safeguarding the health of plants and the safety of agricultural products.
Nutrient Density
Nutrient-dense soil, achieved through proper management, translates to nutrient-dense crops, promoting human health through the consumption of nutritious food. Soil amendments and organic matter incorporation enhance nutrient availability, contributing to the nutritional quality of harvested produce.
Food Sovereignty
Soil health is essential for ensuring food sovereignty by maintaining fertile land for local food production. Sustainable agricultural practices empower local communities to have control over their food systems, promoting self-sufficiency and resilience.
Climate change mitigation
Carbon Sequestration
Soil is a crucial carbon sink, and regenerative soil practices enhance carbon sequestration, mitigating climate change.
Water Retention and Drought Resilience
Improving soil structure and organic matter content enhances water retention, reducing the impacts of drought and supporting resilient ecosystems.
