With the objectives of assessing variations in soil physical and chemical properties, two tillage types: Agroforestry based Conservation Tillage (AFCST) and Maize (Zea mays) based Conventional Tillage (MCVT) under three age categories (5,10 and 15-years) were selected in Chichu and Haroresa Kebels, Dilla Zuria, Ethiopia. A total of 48 composite soil samples (4 replication 2 tillage types 3 age categories 2 soil depth layers: 0-10 cm and 10-20 cm) and additional undisturbed core samples were used to determine soil bulk density (g cm-3).
