Phosphorus Availability from Thermally Altered Phosphate Rock

O. O. Adesanwo^*, A. A. Lasisi, O. B. Ojewande

Several studies have shown that the effectiveness of phosphate rock (PR) as phosphorus source for direct application is largely determined by the extent of its dissolution in moist soil. An incubation experiment was carried out in the Soil Science laboratory of Obafemi Awolowo University to monitor the rate of P release from thermally altered Ogun phosphate rocks (OPR) and mineral P fertilizers (S...

Remediation of petroleum polluted soils with organic manures and inorganic fertilizer and its effect on fluted pumpkin (Telefeira occidentalis) in Bayelsa State

Teknikio, J. B^*, Diri, K. H, Unabor, E.

Growth parameters of fluted pumpkin (Telefeira occidentalis) were examined to assess the effectiveness of remediating crude oil-polluted soils on application of organic manures and inorganic fertilizer in enhancing hydrocarbon-degrading bacteria (HDB) used in the bioremediation process in Bayelsa State. Two locations, Imiringi and Koloama, in Ogbia and Southern Ijaw Local Government Areas, respect...

Effects of Different Organic Amendment Sources on the Physico Chemical Properties of a Nutrient Depleted Vertisol

Moji K.T^*, Jibrin M. J., Umar F. G., Bashir A.Y

The decline in soil organic matter, nutrient depletion, and loss of soil fertility due to soil degradation contribute to low agricultural productivity. Organic amend- ments (OAs) have the potentials to reverse soil degradation processes by improv- ing the soil's physical and chemical properties and consequently improve crop growth and yield performance. At Cranfield University, United Kingdom, a g...

Soil Health, Our Health: Effect of Paint Effluent Contaminated Soil on the Heavy Metal Content

Igwe, C.A, Nwachukwu O. I.^*

A study was conducted at Michael Okpara University of Agriculture, Umudike to evaluate the growth and tissue metal content of Abelmoschus esculentus in soil which had been subjected to long term dumping of paint factory waste. Agronomic parameters stem girth, leaf length and plant height of Okra plant were measured at two week intervals, and after 12 weeks of growth, the soil, roots, leaves and fr...

Erodibility and Gully Erosion in Relation to Soil Properties in Akwa Ibom State, South Eastern, Nigeria

Ogban P. I.^*, Edoho, I. J

This study was conducted to evaluate soil physical and chemical properties in relation to erodibility and gully erosion in Akwa Ibom State, South eastern Nigeria. The locations of study were three gully erosion sites/ types, namely, active and meta-stable (ms-1 and ms-2) gullies. Results of the study showed that coarse sand (CS) particles averaged 863, 710 and 800 gkg-1 in the active and ms-1 and ...

Different Forms of Potassium and Their Contributions Toward Potassium Uptake Under Ginger (zingiber Officinale Roscoe) Production in an Ultisol of Umudike, Southeastern Nigeria

Okeke V. N.^*

To identify the quantity of optimal rates of zinc fertilizer needed for maximizing Vigna radiata yield, a greenhouse and field studies were conducted in two cropping seasons. For the greenhouse, zinc sulphate was applied at five dosages (0, 5, 15, and 20 kg ha-1) and at seven dosages (0, 3, 6, 9, 12, 15, and 18 kg ha-1) for field study. The sandy loam (SL) soil samples had modest levels of OC (1.0...

Characterization and Classification of Rice - Growing Soils on Igbaku Sandstones Residua and Current Suitability for Rice Production in Anambra State, Eastern Nigeria

Asadu Charles Livinus^*, Onyeme E

"The soils on Igbaku sandstones residua were sample at Ifite Ogwari in Anambra state Nigeria to characterize, classify and evaluate their current suitability for rice production. Following several auger borings, a modal profile was sited dug, de- scribed and sampled. Data from it and representative auger points are presented. The soils generally belong to loamy textural classes or finer, especiall...

Impact of Land Use on Spatial Distribution of Soil Nutrients in Akure North and Akure South Local Government Areas of Ondo State, South West Nigeria

Dada B. F^*, Ewulo Babatunde Sunday, Awodun M.A., Ajayi S.O., Olajire O.O.

Land use has great impacts on the distribution of nutrients in soils, Anthropogen- ic activities and recorded increase in population density in the study area is ex- pected to lead to great changes in the soil spatial nutrients distribution, data on the spatial distribution of nutrients in Akure North and South Local Government Area (LGA) of Ondo state is scarce, therefore it is important to fill ...

Micronutrient Distribution in Soils of Ethiope Region of Delta State, Nigeria

Ojobor, Smart. A.^*

Investigation was carried out in Ethiope Region of Delta state, Nigeria to evalu- ate the distribution of micronutrients contents of oxisols. Ten farming communi- ties were purposely selected in the region, and a total of 60 composite samples were collected with the aid of augers at a depth of 0 - 30 cm. The samples were air-dried at room temperature, sieved with 2 mm sieve mess before subjecting ...

Variability of Some Soil Properties Along a Toposequence in a Basaltic Parent Material of Vom, Plateau State Nigeria

Mahmud A.T^*, Hassan I.M, Shehu B.M, Samndi M. A.

Topography influences the distribution of some soil physical and chemical properties. This study assessed some variation in soil properties resulting from the topographic effect on Basaltic parent material at Vom Jos Plateau State in the Southern Guinea zone of Nigeria. Soil samples were collected at an interval of 20 m and at depths of 0 to 15cm and 15 to 30 cm, parceled, labeled and taken to the...
