Fertility Capability Classification of Acid Sands (Soils) as Influenced by Parent Materials in Akwa Ibom State, Nigeria

B. T. Udoh^*, Ogunkunle A. O., U. S. Akpan

Fertility capability classification (FCC) was carried out using data obtained from a field survey of acid sands soils in the Niger Delta area of Akwa Ibom State. The soils were studied on the basis of their parent materials, namely, coastal plain sands (CPS), beach ridge sands (BRS), sandstone/shale (SSS) and alluvial deposits (ALD). The result showed that most (60%) of the pedons from CPS had san...

The Effect of Rice Husk Dusts Treated with Urine on Soil Fertility Status and Yield of Upland Rice in Abakaliki, Southeastern, Nigeria

Igboji P O^*, Onyibe, C.E

To enhance nutrient release by rice husk dust, it was treated with human urine, swine slurry and water, with an untreated rice husk dust and control (no rice husk dust) as standards. These treatments were laid out in the field in a Randomized Complete Block Design (RCBD) replicated four times. The result shows that human urine decomposed material recorded pH of 5.89 (medium acid), total organic ca...

Effects of Application of Compost and Inorganic P on Soil Chemical Properties and Maize (zea Mays L.) Growth in an Ultisol.

Ekundayo R . A.^*, Olayinka A.

The aim of this study was to assess the effects of separate and combined applications of composted poultry droppings and inorganic P on soil chemical properties and maize (Zea mays L.) growth in an Ultisol. The study was carried out in the screenhouse at Obafemi Awolowo University, Ile-Ife (latitude 70 321 N and 70 331 N and longitudes 40 321 E and 40 401 E). Bulk top soil (0-15 cm) sample was col...

Profile Distribution of Crystalline and Amorphous Sesquioxides in Talc Overburden Soils of Southern Guinea Savanna Ecology in Nigeria

AJIBOYE G. A.^*, Ogunwale J. A., Aduloju M. O.

The stage of development of soils developed over talc overburden in two locations (Ejiba and Odo- Ogbe) within the Southern Guinea Savanna Agro-ecology of Kogi State, Nigeria, were evaluated using the dithionite and oxalate extractable Fe, Al oxides and the ratios of silt: clay and silt: silt +clay of the soils. Soil samples collected from the pedogenic horizons of nine profile pits dug in the two...

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, CM...

Forms of Zinc, Cobalt, and Chromium in Soils Cultivated to Oil Palm and Rubber in the Rainforest

EMOMU Adams^*, Ehis- Iyoha E.

The study aimed to determine the status of six forms of Zinc (Zn), Cobalt (Co), and Chromium (Cr) in soils cultivated for Oil palm and Rubber in the rainforest belt of Nigeria. Soils were collected from 2 (Oil palm and Rubber) plantations using a Randomized complete block design from 4 depths in 3 replications to make a total of 24 soil samples. A Laboratory experiment was conducted in the soil an...

Effects of Rice Bran-Mulch on the Growth of Sorghum and Millet in Maiduguri, Semi-Arid North-East Nigeria.

EZE P. C.^*, ALHASSAN, A. B., TSADO P. A., Onyekwere I N, Samson Joshua Kwari, DADA Y. M..

In 2009, an experiment was carried out under rain-fed conditions at two sites to evaluate the influence of three rates of rice bran-mulch on the growth of sorghum and millet on a sandy loam soil in Maiduguri, Semi-arid North-east Nigeria. The study comprised six treatments replicated four times and laid out in a split-plot design. Following land preparation, rice bran was uniformly applied on the ...

Quantitative Analysis of Humic Substances in Soils Treated with Different Organic Manures in Sudano - Sahelian Savanna, Northeast Nigeria

Wapa J. M^*, OJENIYI STEPHEN OLUSOLA, Sandabe M.K

This work was carried out to study the effect of organic manures on different fractions of soil organic matter. 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 types of organic manures (cow dung, city refuse and poultry droppings) applied at thr...
