Nitrogen Dynamics of Vermicompost Use in Sustainable Agriculture

Vermicomposting is a process where worms are used to transform organic waste products into fertilizers for agricultural use and as soil amendments to improve soil health. Vermicompost is used in agriculture as both an organic fertilizer and a soil amendment due to its large biological component and abundant nutrient concentrations, in particular nitrogen (N). Vermicomposts promote soil microbial biodiversity by...

Characterization of problem soils in and around the south central Ethiopian Rift Valley

Some soils in Ethiopia reduce plant productivity due to physical and/or chemical limitations. The morphological, physical and chemical properties of problem soils, including sodic, acidic, and saline soils, around southern Ethiopia were characterized and are described in this chapter. The intention is to characterize the soils and better understand the specific nature of the limitations. Sodic soils of Alage, acid soils...
