Soil structure stability and organic carbon distribution along the toposequence of Orumba North in derived savannah of the South-East, Nigeria

Chika Jidera*, Ezeokoye, C.S., Sunday Ewele OBALUM, Ukaegbu E.P.

In high-rainfall zones with severe water erosion problems, soil structure stability as promoted by soil organic carbon (SOC) should be prioritized. Landscape positions and land use influence soil properties and nutrient distribution. This study assessed soil structure stability and SOC content at top-slope, mid-slope and low-slope positions of a to...

Influence of Tillage - Seedbed and Manure - Npk - Micronutrient Management Options on Selected Soil Properties of Sandy - Loam Ultisols Evaluated Using Sweet Potato

Sunday Ewele OBALUM*, , Ogumba P.O., Uzoh I .N

This study assessed the effects of tillage and nutrient management practices on selected soil properties of degraded coarse-textured Ultisols and responses of sweet potato in Nsukka, southeastern Nigeria. It involved three tillage-seedbed types viz zero-tilled flatbed (ZT-FB), conventionally tilled-flatbed (CT-FB) and conventionally tilled tie-ridg...

Influence of Granulometric Composition and Organic Matter Management on Soil Stability Against Water Erosion in Southeastern Nigeria

V. I. Ezeaku*, Sunday Ewele OBALUM, Peter I. Ezeaku, Igwe, C.A

The study investigated the influence of granulometric composition and organic matter on soil stability and eroded sediment under simulated rainfall for some soils from southeastern Nigeria. The experiment was conducted at the Glasshouse of the Department of Soil Science, University of Nigeria Nsukka (UNN). The experimental design was a 3 x 3 factor...

Effect of Land Use Type on Organic C, Physical Properties and Stability Indices of Soils in Nanka Area, Southeast Nigeria

Uzoh I .N*, Igwenagu C.M, Sunday Ewele OBALUM

This study was conducted in Ifite-Nanka, Orumba North L.G.A. in Anambra state, Nigeria. The aim of the research was to evaluate the effect of three land use types on soil organic carbon (SOC) and physical properties and to determine the factors that contributed to the stability of the eroded sites. Horizon variability of these soil parameters was a...
