Chapter 18: Enhancement of Soil Fertility and Nutrients Sustainability on Arable Crops Production in Agroforestry Ecosystem Nsien, I. B., Okonkwo, H. O., Akpan, U. F. and Eric, E. E.

CONCLUSION
Soil fertility and nutrients status anchored on natural phenomenon like nutrient cycling, nitrogen-fixing plants through nodulations, bush fallow system and also through soil amendments like organic manures, mineral fertilizers and leaf litters decomposition. The paper highlighted precipitation pathways in which nutrients accrued to the soil through agroforestry ecosystem. Soil fertility enhancement and nutrients status could be maintained and sustained through application of manures (organic and inorganic fertilizers); practiced of traditional bush fallow system, improved bush fallow, mixed cropping system, crops rotation, shifting cultivation and nitrogen-fixing plants. The paper also emphasized that agroforestry system have the potential to address a number of land-use problems such as low soil fertility, fodder, fuelwood and small timber shortages and soil water erosion, if designed appropriately. Restoration, sustainability and productive land-use systems via agroforestry system have been proven to enhanced soil fertility, increased crops performance and yields; and also maintained ecological balance.BOOK CHAPTERS 2026 READY.docx 18
