This program is about the pivotal role of soil biology and biodiversity in the maintenance and regeneration of soil fertility. It highlights the pressing issue of low soil fertility and the scarcity of resources in the Solomon Islands. Encouraging the proliferation of soil organisms and biodiversity emerges as a strategic approach to bolster or restore soil fertility and promote plant health in rural areas where farmers lack access to, or cannot afford, inputs like fertilizers. This program strongly advocates for the promotion of soil organisms within agro-ecosystems as an essential nature-based and ecosystem-based solution to tackle soil fertility challenges.
