What makes soil come alive?
Healthy soil is full of tiny living organisms that recycle leaves, roots and organic matter into nutrients for plants. This theme explores how microbes, earthworms and fungi work together to build fertile soils, recycle nutrients naturally and store carbon. By studying regenerative farming, children can discover how healthy soils support healthy ecosystems.
🍂 Comparing local leaf decomposition: for example; you may investigate how locally available leaves or plant materials decompose in your soil. You may also compare decomposition rates and soil life with teams using different plant materials or soils from other regions/ branches/ climatic conditions.
🌿 Biochar & Soil Health: for example; children in teams may study how biochar or other natural soil amendments affect soil moisture, plant growth and soil organisms. They can also compare whether their benefits vary under different soils or climatic conditions.
🪱 Soil Biodiversity Survey: for example; children may observe and record earthworms, insects, fungi and other soil organisms in your local soil. They may also compare biodiversity across farms, schools or regions to understand how climate and land use influence soil life.
♻️ Natural Nutrient Recycling: for example; children could explore how compost, leaf litter or crop residues improve soil health in your community. Compare nutrient recycling practices used in different regions and identify the most sustainable approaches.
