Soil Vulnerability and Degradation Assessment of Mountainous Area in Ekoli - Edda, South - East Nigeria

Ekpe, I I*, Oludare C. G,, Oti, N.N, Ishiusah O. W,, Egboka, N.T, Amarachi Orji, Nwankwo V.C.

Soil vulnerability and degradation assessment of the mountainous area in Ekoli-Edda, South-East Nigeria was carried out on four experimental sites namely Egu, Ugwuelu 1, Ugwuelu 2, and Ocha. The slope of each study site was divided into three namely summit, mid-slope, and foot slope, and slope attributes were measured. Two profile pits were sunk equidistance apart at each of the slope positions an...

Influence of Forms of Iron and Manganese Oxides on the Physical and Chemical Properties of Soils Formed Over Mica - Schist in a Northern Guinea Savanna, Nigeria

Kefas, P. K*, Abdulrashid Shobayo Babatunde, Ofem, K.I, Akwoga, J.A, Asadu Charles Livinus, Peter I. Ezeaku

Three forms of oxides of iron and manganese were evaluated on soils developed in mica-schist lithology within the basement complex formation of Taraba State, North-eastern Nigeria. The results from the three oxide forms namely, pyrophos- phate extractable (Mnp/Fep), oxalate extractable (Mnox/Feox) and citrate- bicarbonate-dithionite extractable (Mnd/Fed) examined were subjected to both descriptive...

Genotypic Effect of Groundnut on Nodulation, N Fixation and N Balance in the Two Savannahs of Nigeria

Terngu Kenneth Moji*, Jibrin Muhammad Jibrin, Umar F. G., Abubakar U. D

Identification of high N-fixing groundnut genotypes and integrating them into the prevailing cereal-based cropping systems can reduce the need for nitrogen (N) fertilizers, thus minimizing their high cost and associated environmental consequences. This study was conducted to estimate the amount of symbiotically fixed N by groundnut genotypes and its contribution to soil N and yield of groundnut. T...

Effects of Rice - Bran Compost on Growth and Yield of Soybean (glycine Max) on an Alfisol in Ibadan, Nigeria.

Adegoke J.O*, Abel O. O., Joseph-Adekunle T.T.

Farmers in the tropical environment face the acute problem of sing mineral fertilizers due to their unsustainable attributes ranging from scarcity and high cost of the material to the adverse effects on tropical soil which resulted to soil acidity and pollution of underground water. This study evaluated the effects of rice-bran compost on the growth and yield of improved variety of soybean on an A...

Geochemistry of Major Elemental Oxides on a Lithosequence in Kaduna State Nigeria

Lemuel Musa Maniyunda*, Bashiru Ademola Raji, Odunze Azubuike Chidowe, MALGWI W.B.

Geochemistry of major elemental oxides of soils developed on basement complex rocks namely: older granite (OG), migmatite gneiss (MG), mica schist (MS) and quartzites (QZ) was studied in Kaduna State. The contents of major elemental oxides were similar in the soils, except for K2O and TiO2 that varied significantly between the soils. Relative weathering intensity showed significant variation in al...

Using Urea Intercalated Biochar and Organic Fertilizer as Soil Management Option Part 1: Main Effects on Soil Properties and Carbon Implication

Tijani F. O.*, Adewumi T. M., Abdulraman O. A., Oyebola O. K., Adebayo A. A., Amosun E. O., Oyedele D. J.

The study evaluated the effect of application of some fertilizers on soil carbon dioxide evolution and unsaturated hydraulic conductivity (Kunsat) at daily time scale, while other soil properties were assessed at the end of the experiment. The factorial experimental design was based on completely randomized design replicated three times. 4 kg of the prepared soil was weighed into each pot and trea...

Water Characteristics of Soils Under Different Rates of Poultry Manure in an Ultisol of Southeastern Nigeria

Enyioko C. O*, Akande S. O, Okon, A. B

The effect of different rates of poultry manure application on water characteris-tics of Oforola soils was studied. The different poultry manure rates were 0, 10, 20, and 30 t/ha, while the soil properties studied were particle size distribution, bulk density, porosity, organic matter, saturated hydraulic conductivity, volumet-ric water content, volumetric infiltration rate, sorptivity and water r...

Enhancing Maize (zea Mays L.) Growth and Nutrient Uptake Via Application of Water Hyacinth (eichornia Crassipes [mart.] Solms) Compost and Inorganic Nutrients

Atere C. T.*, Olayinka A.

A soil culture experiment was conducted in the screenhouse to assess the growth response of maize to water hyacinth compost application rates and their residual effects. Water hyacinth (Eichhornia crassipes [Mart.] Solms) compost, namely, 2.5 t ha-1(W1) and 5.0 t ha-1 (W2) with and without fortification with fertilizer, F [N (25 kg ha-1 as urea) and P (26 kg ha-1 as SSP)] were mixed with portions ...

Soil Structural and Chemical Conditions After Disposal of Fabric Dye on a Loamy Sand Soil in Southwestern Nigeria

Fadare F. J., F. K. Salako, ADESODUN Johnson Kayode*

The indiscriminate disposition of dye waste water from the age-long “Adire” industry of Abeokuta, southwest Nigeria is a major concern as the movement of such contaminants in the soil needs to be monitored. This study investigated the effect of fabric dye on soil physical and chemical properties. Treatments were local concentration, spent local-concentration, half local- concentration and twice lo...

The Relevance of Biochar Technology to Sustainable Soil Productivity and Crop Production in Organic Farming Systems

Fagbenro J. A.*, O. A. Onawumi

The desire for sustainable and productive agriculture is universal but the means to progress towards it remains elusive. This is why organic farming, as a more sustainable form of agriculture than the conventional type, is being advocated by various organizations the world over. However, the organic farming system, as it is currently practised, is not necessarily, truly sustainable in terms of soi...
