Abstract
Soil amendments e.g., manures and biochar improve the soil physical, chemical, and biological properties and enhance soil organic matter content. Despite their positive effects on soil health and crop production, soil amendments are lost as CO2, in gaseous and liquid formats. Thus, there is need to study the effects of soil amendments (manure and biochar) on CO2 emission under specific climatic conditions, soil characteristics, and crop management practices. This study investigates the effects of the application of different soil amendment types (chicken and dairy manures) at three rates (0, 224, 448 kg total N ha-1) and biochar at two rates (2.5 t ha-1 and 5.0 t ha-1) on soil carbon dioxide (CO2) emission under a sweet corn crop. The experimental design was a factorial design with three replications and experimental 39 plots. The size of each plot is 3.04 m x 2.44 m. Soil amendment was applied and mixed manually into the top 15cm- soil depth. Carbon dioxide fluxes were measured twice a week for the duration of the cropping season. Irrigation, rainfall, soil moisture content, and soil temperature were also periodically monitored from each plot.
