Soil quality improvements provide an environment for plant nutrients uptake that influences the development and yield of the crop. This study evaluated the effect of applied composted poultry manure (CPM) on selected soil physical attributes and soil organic carbon content (SOC) under two tomatoes (UC82B and BESKE) varieties planted in succession. Three rates: 0, 10, and 20 t/ha of CPM was applied to two tomato varieties. The treatments were arranged in a randomized complete block design. The parameters considered are soil physical properties - bulk density, aggregate stability, total porosity, water retention capacity, and SOC. It was observed that the application of CPM increased SOC, total porosity, saturated hydraulic conductivity, aggregate stability and decreased bulk density in the tomato cropped area. Water retention did not show any significant difference (P<0.05) between depth at different suctions (0, 30,100 kPa). The SOC was highest in 10 ton/ha of CPM. Application of 10 ton/ha compost is adequate to improve carbon content and soil physical properties for studied soil.
