Changes in a Tropical Ultisol Under Different Management Systems in Southeastern Nigeria: 1. Soil Physical and Hydrological Properties

Omenihu A. A.*, Opara-Nadi O.A

Five soil management practices were compared to evaluate their effects on soil physical and hydrological properties in a cassava/maize intercrop. The management practices compared over four years (2003 – 2006) at Umudike in the rainforest zone of southeastern Nigeria were fallow-grazing-cropping (FGC), traditional farming (TF), no-tillage (NT), minimum tillage (MT) and conventional tillage (CT). T...

Fertility Status of Fadama Soils in Asaba, Delta State, Nigeria

Ojobor Smart*, Aimufia, Precious Nosakhare

An experiment investigated the fertility status of fadama soils in the Asaba environment, Delta State. The study area was divided into twelve blocks, and ten representative soil samples were taken from each block to form one composite sample that was air-dried at room temperature and sieved with a 2 mm sieve. Particle size distribution, soil pH, organic carbon, total N, available P, exchangeable b...

Characterization and Classification of Soils of Jalingo Metropolis, North - East, Nigeria

Osujieke D.N.*, Obasi N.S., Imadojemu P.E., Ekawa M., Angyu M.D.

The study was aimed at the characterizing and the classifying of soils of Jalingo metropolis in Taraba State, North-East Nigeria. Profile pit was dug on each of the three different sites of the study area as identified using free survey. The profile pits were described and sampled bases on horizon differentiation for laboratory analyses. A total of 10 samples were collected. Data generated were an...

Yield of Sorghum and Millet as Affected by Rice Husk – Mulch on a Sandy Loam Soil in Maiduguri, Semi-Arid North-East Nigeria

EZE P. C.*, ALHASSAN2, A. B., Samson Joshua Kwari, DADA Y. M.., TSADO P. A., LAWAN A. N..

A split-plot experiment with four replications was conducted at two sites in Maiduguri, Semi-arid North-East Nigeria to evaluate the influence of three rates of rice husk-mulch on the growth and yield of sorghum and millet on sandy loam soil. Rice husk was uniformly applied on the soil surface of plots measuring 8 m x 4 m. Crop husbandry was carried out. After crop harvest, grain yield, stover yie...

Occurrence of multi-class pesticide residues in soils of selected farmlands and farmer’s household surroundings in the southwestern part of Oyo State, Nigeria

Shade Akinsete*, Ibiwumi K. Saliu

The indiscriminate use of pesticides for crop production in Nigeria has led to contamination of the environment. Specifically, soil contamination from pesticide residues, including banned compounds raises serious public and environmental health concerns. However, very little is known about the occurrence of pesticides in Nigerian soils. Therefore, this study investigated the occurrence and concent...

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.*, M.E. Obi, 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, , Ezeaku, P.I., 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....
