Soil Chemical Properties and Agronomic Response of Sugarcane (Saccharum officinarum L.) Affected by Long Term No-Tillage Practice and Bagasse Mulch Application
Zaqyah, Irene, Niswati, Ainin, Evizal, Rusdi
Intensive tillage will continuously reduce soil quality, characterized by decreased soil organic-C. Low soil organic-C indicates the disturbance of soil fertility. More conservative soil management experiments have been done for seven years to restore the soil quality for sugarcane (Saccharum offici...
