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...

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 ...

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...

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

Fadare F. J., Salako F. K, 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...

Impact of Soil Erosion on Land Degradation in Uga Southeastern Nigeria

Obiageli Patience Umeugochukwu*, Ezeaku P, V O Chude, G U NNAJI

This study was to investigate the causes and hazards of soil erosion in Uga, Anambra State as the area is always having the problem of erosion. This study was carried out in some selected erosion sites in Uga. The study investigated the impact of soil erosion on land degradation and its environmental hazards in Uga Southeastern Nigeria. Two profile pits were prepared, one on severely degraded (ero...

Sole and combined effects of Mexican sunflower, cabbage residue, and poultry manure on soil chemical properties, growth, and yield of golden melon (Cucumis melo L.) in a derived savanna ecology of Nigeria

Adekiya, A.O*, Aboyeji, C. M, Gbadamosi, A.

Hitherto, the knowledge about the effect of mexican sunflower, cabbage residue, and poultry manure residues in the soil chemical conditions is still limited. Hence, a field experiment was carried out in 2020 to assess the effects of sole and combined applications of mexican sunflower (Tithonia diversifolia) leaves, cabbage (Brassica oleracea) residue and poultry manure on soil chemical properties ...

Effects of Land Use on Forms of Phosphorus in Coastal Plain Sands of Nigeria

Obi J. C.,*, Ibia, T. O, Ikott, I. E.

This research studied the effect of land uses changes on the forms of phosphorus within the coastal plain sands landscape of southeastern Nigeria. Satellite imageries and soil data including phosphorus fractions were used for the study. Spatial coverage of forest and agricultural (fallow and farmland) land uses, accompanying soil properties and forms of phosphorus were estimated. There was progres...

Tillage and Residual Effect of Some Organic Amendments on Aggregate Associated Soil Carbon of an Ultisol, Growth and Yield of Maize and Cowpea Intercrop

Onunwa A.O.*, Igwe C. A, Mbonu O. A

associated soil carbon (C WSA) and yield of maize and cowpea intercrop in an Ultisol, Southeastern Nigeria. A land area of 0.1125 ha was planted to sole cowpea, sole maize and maize-cowpea intercrop using minimum tillage (NT) and conventional tillage (CT) with poultry droppings (PD), pig waste (PW), and Cassava peels (CP) as amendments at the rates of 20, 90, 100 t/ha respectively and a co...

Phosphorus Status in Some Soils of Mid - Western Agro - Ecological Zone of Nigeria

Orhue, Ehi Robert*, John Kingsley

The trial was carried out to determine the status of various forms of P in soils formed on 3 types of parent materials in Southern Nigeria. Soil samples were obtained from3 ha area in each of the locations at 0-15 cm and 15-30 cm depth and then subjected to routine physical and chemical analysis. Results revealed that the sand component of the soils which ranged from 771 gkg-1 to 892 gkg-1 decreas...
