Effect of Organic Matter on Soil Chemistry of Composted Mounds under Sweet Potato Production in the Highlands of Papua New Guinea

Topas M. Peter & Patrick S. Michael · International Journal of Plant & Soil Science · 2026

The reduced fallow period and continuous cultivation of sweet potato on the same land have resulted in the depletion of soil nutrients and poor yields in Papua New Guinea (PNG) highlands, necessitating improved soil fertility management practices. In this study, we conducted a fi...
