The short-term effect of coffee husk biochar application in acidic soils on soil properties, root mycorrhization, pest, and disease management and yields in Robusta coffee and black pepper plantations in Gia Lai province, Vietnam(09/12/2025)
Abstract Vietnam is the world’s leading exporter of Robusta coffee and black pepper. However, the widespread use of intensive cultivation practices has contributed to progressive soil acidification and an increasing incidence of soilborne diseases, threatening the long-term sustainability of these high-value crops. This study evaluated the short-term effects of applying coffee husk-derived biochar (2.5 t ha−1) on soil quality, pathogen suppression, and crop performance in acidic soils of coffee and…
