Characterization and Classification of the Soils of Bukuru - Jos, North Central Nigeria

Kwaghe, E.J.*, Akamigbo, F.O.R., Igwe, C.L

Twelve profile pits were sunk, four in each of the three locations of Bukuru, the study area. Proper soil profile description was done and recorded to obtain field characterization data after which thirty-six soil samples were collected from all the genetic horizons for soil characterization. Bukuru soils showed higher sand fraction (71%) than silt (12%) and clay (17%) at the topsoil but showed in...

Effect of Phosphate Rock Addition on Soil Organic Matter

O. O. Adesanwo*, Adetunji M. T, S. Diatta

The fertilizer treatments consisted of four rates of Ogun phosphate rock (0, 30, 60 and 90 kg P ha-1) and triple super-phosphate at 40 kg P ha-1. Legume treatment consisted of Mucuna and cowpea and were planted as pre-rice crop. Soil samples were collected and analyzed for organic carbon. Four pellets of Ogun phosphorites labeled OG1, OG2, OG3 and OG4 was randomly selected and subjected to X- ray ...

Effect of Tillage and Crop Residue on Soil Chemical Properties and Rice Yields on an Acid Ultisol at Abakaliki Southeastern Nigeria

Ogbodo E. N*, P. A. Nnabude

A study was conducted in 2008 and 2009 raining seasons, to evaluate the possibility of alleviating the degraded soil conditions at Abakaliki. The measures employed were combination(s) of different tillage methods [No-Tillage (NT), Hoe Tillage (HT), Ploughing (PL) and Ploughing and Harrowing (PH)] and crop residues [No Residue (NR), Rice Straw (RS), Burnt Rice Straw (BRS) and Legume Residue (LR)] t...

Use of Point - Based Pedotransfer Function to Predict Field Capacity of the Soil in Nsukka Area, Southeast Nigeria

Obidike-Ugwu E. O.*, Obi Martins Eze, Anikwe M. A. N

Point-based pedotransfer functions are attractive for modelling soil water content, however, they have not been widely applied to predict field capacity (FC) of weathered tropical ultisols. Determination of field capacity at Nsukka area, was carried out using field and laboratory methods. Soils in the location were gravelly (Plots E and F) while others (Plots A, B, C and D) were deep and permeable...

Characterization and Identification of Contemporary Diagnostic (b) Horizons of Some Soils in Ideato North Local Government Area of Imo State Southeastern Nigeria

Onyekanne, C. F.*, Uzoh I .N, Peter I. Ezeaku, Akamigbo, F.O.R.

Most soils in Nigeria have not been characterized and classified based on diag- nostic B horizon and identification of diagnostic B horizon is essential in the study of soils. As a result, this study was carried out to characterize and classify these soils with special emphasis on the identification of diagnostic B- horizons. A free survey method was employed to locate the representative profiles....

Structural Dynamics and Productivity of a Paleudult Amended with Agro - Wastes in Abakaliki, Southeast Nigeria

Nwite, J.N, Njoku C.*, Nwogbaga, A.C

This research was conducted in 2015, 2016 and 2017 cropping seasons in the Department of Soil Science and Environmental Management, Ebonyi State University Research Farm to determine the effect of agro-wastes on soil structural dynamics, productivity and maize grain yield. Treatments were laid out in Randomized Complete Block Design (RCBD) with four treatments replicated five times. The treatments...

Effect of Groundnut (arachis Hypogea )residues on Soil Chemical Properties in the Sub - Humid Southern Guinea Savanna Zone of Nigeria

Achor O.I.*, S.A. Ayuba, A. Ali

This study was conducted at the University of Agriculture Makurdi Research Farm in the Sub- Humid Southern Guinea Savanna zone of Nigeria during 2008 and 2009 cropping seasons to determine the effect of groundnut (Arachus hypogea) residues on the growth and yield of maize (Zea mays). Five treatments (0.4, 6.8 and 10 t ha-1) groundnut biomass were laid in Randomized Complete Block Design (RCBD) and...

Characterization, Taxonomic and Fertility Capability Classification of Some Soils in the Teaching and Research Farm of Taraba State University, Jalingo

Peter I. Ezeaku*, Kefas, P. K, Hashim, S.A.,, Ali I J, Gisilanbe Solomon Adamu, Kussy J J, Garpiya B. T, Yusuf B, Udoh S, V. I. Ezeaku

Result-oriented and competitive agricultural production system requires soil characterization and land evaluation. The soils of the Teaching and Research Farm of Taraba State University were characterized, taxonomically classified and evaluated for fertility capability classification. Three mapping units were delineated using a semi-detailed survey method, and profile pits were dug in the mapping ...

Local Soil Classification [Soil Association/Soil Slope–Soil Series], World Reference Base, and Usda Soil Taxonomy: Roles in Soil Survey Execution.

Okusami, Temitope A.*

The objective was to do a comparative assessment of the best roles of three classification systems, [the “USDA-Soil Taxonomy”, the “World Reference Base (WRB)”, and the presumably Soil Association/Soil Series Concept of Nigeria] in the Soil Survey execution from Soil Mapping through to Soil Survey Report. In this instance, the concern of this paper is mostly what is best applicable when mapping le...

Effect of Nypa Fruticans and Mangrove Species on Soil Properties in Eastern Obolo, Akwa Ibom State

Ogban P. I.*, Dickson, U. S, Ebong, U. P

The study was conducted to evaluate the effect of nypa and mangrove on soil properties to determine whether nypa in displacing mangrove was degrading or aggrading the underlying soil, in Okorombokho Community in Eastern Obolo Area of Akwa Ibom State. The study was carried out in three contiguous loca- tions, namely, mangrove (M) forest, nypa and mangrove (N&M) forest, and bare plot with neither ma...
