  • Reduce environmental impact: Composting helps farmers achieve better waste management and reduces dependency on external chemical fertilizers.
  • Stimulate microbial activity: High-quality compost supports microbial life critical for nutrient cycling and overall soil health.

This approach is perfectly suited for mixed farming systems, where multiple types of organic waste can be combined for maximum benefit. In 2025, composting with cassava leaves is not only a best practice for sustainability—it’s an essential step in integrated soil fertility management.

4. Mulching to Conserve Moisture & Prevent Soil Erosion

Among the 10 uses of cassava leaf, applying leaves as mulch around crops is a primary way to conserve moisture, protect soil, and support healthy root development, particularly important for semi-arid and erosion-prone landscapes across tropical regions.

  • Suppresses weed growth, reducing the need for manual weeding or chemical herbicides.
  • Prevents soil moisture loss; cassava leaf mulch reduces evaporative water loss, allowing crops to thrive under drought conditions.
  • Prevents soil erosion during heavy rainfall events, minimizing nutrient leaching and keeping topsoil in place.
  • Improves soil structure over time, as leaf mulch decomposes and is incorporated into the soil profile.

Spread cassava leaf mulch 3–5 cm thick around the base of crops or across bare soil between plantings. This builds resilience in cropping systems and greatly enhances soil fertility through continuous organic matter input.

5. Biopesticidal Properties: Natural Crop Protection & Integrated Pest Management

Cassava leaves contain biologically active compounds like cyanogenic glycosides, which have biopesticidal properties. In the context of sustainable 2025 agriculture, these natural compounds are being harnessed for:

  • Reducing pest populations (e.g., aphids, caterpillars) when cassava leaf extract or mulch is applied in targeted ways.
  • Supporting Integrated Pest Management (IPM) strategies by reducing reliance on synthetic chemical pesticides.
  • Enhancing soil health—biopesticidal leaf residues break down naturally, causing no harm to beneficial soil organisms.
  • Promoting ecosystem balance within agro-ecosystems, protecting biodiversity while managing crop pests.

To make a cassava leaf biopesticide, leaves can be crushed and soaked in water, and the extract can be sprayed on crops—always following regional safety guidelines for application concentrations.

6. Source of Organic Fertilizer in Agroforestry Systems

In agroforestry systems, the strategic integration of cassava leaves provides a natural source of organic fertilizer to surrounding trees and companion crops. The cyclical process of harvesting cassava leaves, returning organic matter to the soil, and planting diverse crops helps to:

  • Maintain system fertility by continuous input of nutrients from leaf litter decomposition.
  • Enhance biodiversity, as different crops and trees benefit from a shared, nutrient-rich soil environment.
  • Support sustainability, reducing need for external nutrient inputs and enhancing resilience against climate variability.
  • Promote circular agriculture—nothing is wasted, and cassava leaves serve as a valuable resource for the whole farm system.

Regular pruning and application cycles ensure that both cassava crops and the broader agroforest benefit equally. This method has gained significant traction in contemporary soil fertility management.

7. Human Nutrition Supplement: Diversifying Diet and Fighting Deficiency

Although cassava roots are the best known for their high-calorie content, cassava leaves serve as an essential source of nutrition for human populations in many tropical regions. When properly prepared (to remove natural toxins), cassava leaves become a highly effective:
