Fertility status of soils under selected land use types in Orlu, Imo State, Southeastern Nigeria

The study evaluated the fertility status of some land use types in Orlu area of Imo State using elemental ratio. Soil samples were collected from three land use types namely; plantain plantation, oil palm plantation and cassava. A total of 18 samples were collected. Six soil samples were randomly collected from each land use at depths of 0 - 15 cm and 15 - 30 cm. Routine analyses were conducted and Ca/Mg and K/Mg were...

Impact of land use types and soil depths on selected soil physicochemical properties in Fasha District, Konso Zone, Southern Ethiopia

Agricultural activities such as deforestation, continuous cultivation and intensive grazing cause deterioration of soil properties. This study was conducted with the objective to investigate the influence of land use types (cultivated, grazing and forest lands) and soil depths (0-15 and 15-30 cm) on soil properties. Eighteen composite soil samples were collected and analyzed using standard procedures and the data was...

Soil properties and maize (Zea mays L.) growth and yield response to water hyacinth (Eichhornia crassipes) compost application in Lake Victoria Basin, Kenya

The decline in organic matter (OM) content and fertility of soils often contribute to losses in agricultural production. This research determined the effects of water hyacinth compost application on selected soil properties and maize growth and yield during a field experiment conducted between February 2020 and August 2020 in Lake Victoria basin, Kenya. The experiment was conducted in a randomized complete block design...
