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*

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 Bello Muhammad, 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...

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 S. N., 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.*, ALHASSAN, A. B., Samson Joshua Kwari, DADA Y. M.., TSADO P. A., Ngala Adam Lawan

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...
