Characterization, Classification and Agricultural Potentials of Some Coastal Plain Sand Derived Soils in Lagos State

Orimoloye Julius^*, Okpoitari Simeone

Detailed soil surveys were carried out on a total of 194.5 hectares of the land at Igbokuta and Ibomwon areas in Ikorodu and Epe local government areas of Lagos state. Grid survey method was employed, and mapping units were delineated based on soil morphological characteristics examined at an interval of 70m along transects that were laid 100m apart. The soils were classified according to local so...

Micro - Aggregate Indices and Structural Stability of Soils Under Different Management

Udom B. E.^*, Anozie H.

Low water stability of soil micro-aggregates accentuated by increased intensity of cultivation and soil degradation are among the significant issues that draw the attention of Soil Scientists due to their effects on soil physical conditions. The study was carried out to quantify changes in micro-aggregate stability indices of soils on coastal plain sands under contrasting land use and management. ...

Assessment of Some Soil Quality Indicators in Benue State

Adaikwu A.O^*, A. Ali

A study was carried out in 2009 to assess some soil quality indicators. These indicators include the soil pH, organic matter (OM) content, total nitrogen, available phosphorus, exchangeable cations, cation exchange capacity (CEC), saturated hydraulic conductivity and base saturation. The areas included SIWES farm, University of Agriculture Makurdi, Obarike in Oju, National Root Crops Research Inst...

Land Adaptation Strategies Across the Rain - Fed Agricultural States as Climate Change Persists

Towolawi, A.T.^*, Oguntoke, O., Bada, B.S, Adejuwon, J.O.

Acquisition of land for farming activities is hitting hard on the interested small\u0002scale farmers in Nigeria while the available land faces climate change influenced degradation. This current research verified how farmers are coping across four rain-fed (Benue, Edo, Ondo and Niger) states using 1600 copies of pretested questionnaire administered through the multistage procedure. The retrieved ...

Phosphorus Availability from Thermally Altered Phosphate Rock

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

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

Terngu Kenneth Moji^*, Jibrin Muhammad Jibrin, 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...

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 ...
