Abstract

This research paper examined the soil fertility and capability potentials of derived savanna landscapes in Delta State: implication on suitability for food security. The derived savannas of Delta State are vegetation with peculiar land cover because they are adjudged as alien vegetation that exists within the rainforest which is outside the domain of “savanna” grasslands which occurs in the middle belt as Guinea savanna Sudan and Sahel savanna in northern Nigeria. They are termed derived savannas because they are environmental derivatives of anthropogenic disturbances and other factors of nature within the rainforest. Over the years, the derived savannas have either been marginalized, idle or underutilized, as they are either touched by wild bush fires, during the dry seasons or flooded during the wet seasons. The assessment of the soil fertility and capability status of the derived savanna therefore confirmed that they are rich in major soil parameters such as organic carbon content, nitrogen, potassium and others. They are also suitable for hydrotolerant plants. The study justified the derived savanna of Delta State as having the fertility and capability potential to support sustainable ventures for arable farming and general agricultural land use. This is especially true for short-term crops that can mature before the annual flood regime. Also, their usage for arable farming practices will ameliorate food insecurity in the area based on the recommendation of the soil suitability for arable farming.

Abstract

Organic carbon availability is crucial for effective soil capability, suitability, and fertility potentials, which makes it a serious consideration among all soil parameters in the evaluation of soil nutrient availability and general carbon sequestration. This research article explored an appraisal of soil organic carbon content availability across diverse vegetation covers in Delta State, Southern Nigeria, including lowland rainforests, secondary regrowth, and wet grasslands. The study aimed to establish whether significant differences exist in organic carbon availability across the landscapes to determine soil suitability for functional utilitarian purposes. The methodology adopted was strictly a field survey where soil samples were collected in situ across the three different landscapes at depths of 0-15 cm (not meters), which is the zone of nutrient uptake and activity. A total of 90 samples, with 30 collected from each landscape, were drawn based on systematic stratification. The one-way ANOVA revealed no significant difference in soil organic carbon content across the studied landscapes (p = 0.54, p > 0.05), leading to the acceptance of the null hypothesis. This indicates that the landscapes share similar soil fertility and nutrient availability, supporting their equal suitability for agricultural uses, particularly for arable crop production and precision farming in wet grasslands.
