Fertilizer trees are defined as nitrogen-fixing woody perennials used for soil fertility improvement in arable lands and pastures. Although such trees have played a significant role in traditional and improved crop and livestock production systems, their contributions have not received adequate attention in the debate on food security. This article suggests that diversification of agro-ecosystems with fertilizer trees can increase soil N supply, soil organic matter content, and initiate the restoration of agroecological function thereby increasing the productivity of degraded land. They are also an important component of multifunctional agriculture that provides timber, fodder, shade, watershed management, and resilience to climate change. The contributions they can make toward greater food production and the provision of ecosystem services are described in this article. |
