Magnetic Susceptibility and Heavy Metal Contamination in Farmland Soils of Mangu Area, Plateau State, Nigeria

Akanbi, E.S.*, Godfrey B.T, Izam M.M.

Magnetic susceptibility measurements of soil samples collected at depths 0, 15, 30, and 45cm from thirty-three different farmlands within the study area were made using MS2G Sensor connected to Bartington MS 2 susceptibility meter. The concentration of heavy metals in thirty-three soil samples and most used fertilizers in the study area was determined using a flame atomic absorption spec- trophoto...

Response of Soil Sustainability Indicators to the Changing Weather Patterns in Calabar, Southern Nigeria

Okon, P. B.*, Nwosu, N. J., Isong, I. A.

The response of soil properties to changing weather variables revealed soil-environment functionality that is used to know whether soil quality is improving, remain constant or declining. This paper investigates the effects of weather variables (temperature, relative humidity, and rainfall) on soil quality and sustainability and its agro-meteorological implications. Soil samples were collected fro...

Influence of Drying Condition on Decomposition and Nitrogen Mineralization of Legume Leaves

Akintan C.I.*, Ighodaro B.U., Akintan A.O., Ajayi O.K.

The influence of drying condition on the rate of decomposition and nitrogen mineralization of Gliricidia sepium and Acacia auriculiformis leaves were studied when fresh, air dried and sun dried. These were packaged at 50 g/bag in polyvinyl bags and deposited on the field for decomposition. After 4, 8, 16, 32, 64 and 92 days, three bags of each treatment per species were collected at interval from ...

Response of Extra - Early Maize Variety (zea Mays ) to Different Organic Manures in the Drier Sub - Region of Northern Nigeria

Wapa J. M*, OJENIYI STEPHEN OLUSOLA, Samson Joshua Kwari

This work was carried out to study effect of different organic manures on yield of maize in the study area. Field trials were carried out in 2008 and 2009 cropping seasons at the Teaching and Research Farm of the Department of Soil Science, University of Maiduguri, Maiduguri. The treatments consisted of three organic manures (cow dung, city refuse and poultry droppings) applied at four rates of ea...

Evaluation of Integrated Application of Urea and Animal Manure

W. B. Bello*, I. O. Adekunle

A study was carried out at Igboora, South-western Nigeria from 2010-2011 to examine the effect of sole use of poultry and pig manures and their fortification with N fertilizer on performance of maize. The treatments were poultry manure (P) 5 t/ha, Swine manure (S) 5 t/ha, P 2.5 t/ha + 0.2 t urea/ha, S 2.5 t/ha + 0.2 t urea/ha and control. Poultry manure was higher in nutrients than Swine manure. T...

Nutrient Availability to Soybean (glycine Max (l) Merr.) from Ogun Phosphate Rock and Zinc Application in Some South-Western Nigerian Alfisols

Shokalu A. O*, Shokalu O, Adetunji M. T, Jamiu Oladipupo Azeez

The response of soybean (Glycine max (L) Merr.) to phosphorus from beneficiated Ogun phosphate rock (OPR) and zinc application (as ZnO; 80 % Zn) was studied in both pot and field experiments. Pot experiment was conducted with six surface soils collected from 0-20 cm depth of different land uses within Ogun State, Nigeria while the most representative of the locations was used for the field trial. ...

Synergistic effects of poultry manure and 2,4-epibrassinolide on soil properties and performance of groundnut in the rainforest of Nigeria

Victoria Otie*

The growth and yield response of groundnut (Arachis hypogaea L.) to fertilizer and other crop management inputs on Nigerian soils derived from coastal plain sands has been little studied. This greenhouse evaluation was aimed to determine the impact of chicken manure (CM) and 2,4-epibrassinolide (BR) on the growth and yield of groundnut. Four levels of CM: 0, 5, 10 and 15 tons/ha denoted as CM0, C...

Sustainability of Crop Production in Relation to Landscape Position and Soil Properties in Isiama, Abia State

Adesemuyi E.A*, Iroha J. N, Chukwu, G. O.

The research was carried out at Isiama in Umuahia North Local Government Area of Abia State, Nigeria to examine the relationship between landscape positions and some selected soil properties. The soil units studied occupied different landscape positions and were identified as the summit (EJ-1), upper (EJ-2), middle (EJ-3) and foot (EJ-4) slope classes, on 3%, 7%, 2.5% and 1% slopes respectively. O...

Comparison of the Characteristics of Soils of Isolated Forests and Adjacent Grasslands in Nsukka Area of Enugu State, Nigeria

Asadu, C.L.A*, Odugu C.

The soils of isolated forests on hilltops and the surrounding grasslands in three locations at Ashor Hill, AttabaHill, and Umuowo Hill, all in Nsukka area were comparatively characterized. Two auger samples were collected (0-20 and 20-40cm) from each vegetation type per location giving a total of 12 auger samples while two profiles pit each were dug, described and sampled. In all, 24 samples were ...
