Kenyan Farmers Turn to Insect-Based Fertiliser to Restore Degraded Soil

Kenyan farmers are using fertiliser made from insects to restore degraded soil, improve crop production and promote more sustainable agriculture.

The fertiliser is produced from insect waste and organic materials. It contains nutrients that can improve soil fertility while reducing dependence on chemical fertilisers, which may become less effective or damage soil health when overused.

Soil degradation remains a major challenge for farmers in Kenya and across Africa. Erosion, repeated cultivation, deforestation, drought and poor land-management practices have reduced the productivity of farmland and increased pressure on rural communities.

Insect-based fertiliser offers a practical way to address both soil degradation and waste management. Insects can be raised on organic waste, while their residue is processed into a natural soil amendment for use on farms.

Farmers using the product say healthier soil can improve plant growth, strengthen crops and support better harvests over time. The approach may also help reduce farming costs by providing a locally produced alternative to expensive imported inputs.

The initiative forms part of a wider effort to promote circular agriculture, in which waste is converted into useful resources. It could create additional income opportunities for young people and small businesses involved in insect farming, processing and distribution.

However, wider adoption will depend on affordability, reliable supply and farmer education. Producers will also need to demonstrate the fertiliser’s quality and effectiveness across different crops and soil conditions.

Climate change is increasing the urgency of restoring African soils. Healthy soil retains more water, supports biodiversity and helps farms withstand drought and unpredictable rainfall.

Kenya’s experience shows how agricultural innovation can combine environmental protection with economic opportunity. If expanded responsibly, insect-based fertiliser could help farmers restore their land while building more resilient and sustainable food systems.
