Effect of Tillage and Maize - Cowpea Intercrop on Fractal Features of Particle and Aggregate Size Distribution on a Tropical Sandy Loam Soil in Southwest Nigeria

ADESODUN Johnson Kayode*, Udom B. E., Adekunle A. O, Adejuyigbe C. O.,, Atayese M. O., Olowokere F. A., Mbila M., Oyegoke, C.O,

The effects of tillage and cropping pattern on soil aggregation, fractal dimensions and distribution of organic carbon fractions were studied. Treatments were no- tillage (NT), conventional tillage (CT), and four cropping patterns viz: sole maize, sole cowpea, maize-cowpea intercrops and control (no crop). Soil samples were analysed for particle size distribution (PSD), aggregation ratio (AR), mea...

Physicochemical Properties of an Alfisol Under Fallow and Adjacent Forest Lands and Their Suitability for Cocoyam, Pigeon Pea and Sweet Potato Production in Nsukka, Southeastern Nigeria

Ugadu, M.E*, Asadu, C.L.A

Forest land provides a wide range of ecosystem services such as reducing the impact of raindrops on the soil and maintenance of soil fertility, whereas fallowing is one method used in restoring the fertility status of degraded farmlands. This study evaluated the physicochemical properties of an Alfisol under fallow and adjacent forestland, and their suitability for cocoyam, pigeon pea, and sweet p...

Effect of Solid and Liquid Tea Compost on the Growth , Yield of Amaranthus Cruentus and Soil Properties in Ekpoma, Delta State.

Dania S. O.*, Oshokhayamhe B. I, B. I and Uche, A, L.

Improvement of soil nutrient and organic matter contents is essential to enhance the growth and yield of crops. Two seasons experiments were conducted to evaluate the effect of solid and liquid compost on the growth, yield of Amaranthus and soil properties in Ambrose Alli University Teaching and Research Farm, Ekpoma. The treatments (control, compost tea, solid compost) were laid out in Randomized...

Soil Boron and Bio - Accumulation in Raphia Palm

Aghimien A.E.*

Total and available Boron were determined in surface soils from 56 locations on 5 different parent materials in Southern Nigeria. Boron concentrations in leaves of Raphia palms growing in the were also determined. Total, available and plant Boron ranged from 16.0 to 87.0; 0.08 to 2.31; 3.0 to 25.0mg/kg respectively in crystalline metamorphic and igneous rock soils; 22.3 to 69.4; 0.01 to 1.20; 6.0 ...

Heavy Metals Status of Soil and Their Uptake by Fluted Pumpkin (telfairia Occidentalis Hook F) Cultivated Along Ikpoba River Bank, Benin City

Orhue E. R.*, Izunwanne C. L.

This study was carried out to assess the status of heavy metals in the soil and fluted pumpkin cultivated on the bank of Ikpoba River at Benin City. The sample area was 9000 m2. Soil samples were collected at 0-30 cm and 30-60 cm depths at 30 locations giving a total of 60 samples. The plants were also sampled along with the sampling of the soils giving a total of 30 plant samples. Similar numbers...

Spatial Variability of Micronutrients in Termite Infested Soil Formed on Nupe Sandstone in the Guinea Savanna Region of Nigeria

Obi J. C.*, Ogunkunle A. O.

Soil micronutrients are nutrients required by plants in small quantity. They affect plant growth either directly or indirectly. Availability of these elements for crop growth and development may be affected by their distribution on the landscape. Variability in crop yield may indirectly be attributable to soil micronutrient variability. Termites have been implicated through their feeding habit, co...

Influence of Granulometric Composition and Organic Matter Management on Soil Stability Against Water Erosion in Southeastern Nigeria

Ezeaku, V. I*, Sunday Ewele OBALUM, , Ezeaku, P.I., Igwe, C.A

The study investigated the influence of granulometric composition and organic matter on soil stability and eroded sediment under simulated rainfall for some soils from southeastern Nigeria. The experiment was conducted at the Glasshouse of the Department of Soil Science, University of Nigeria Nsukka (UNN). The experimental design was a 3 x 3 factorial in CRD replicated three times and involved thr...

Response of Soybean (glycine Max L. ) to Cow Dung and Wood Ash Application in Tropical Acid Soils of South - Western Nigeria

Soretire A. A.*, Olayinka A.

The study examined the effect of cow dung (beef cattle manure) and wood ash on the growth and yield of soybean in two acid soils (Typic dystrudepts) of south-western Nigeria. The experiment was conducted under field conditions at two different locations, namely, Epe and Ibiade (Ijebu- waterside) of Lagos and Ogun States, Nigeria, respectively. It was a 3 x 3 factorial experiment arranged in a rand...

BIOACCUMULATION OF HEAVY METALS IN SOILS, Talinum triangulare and Celosia argentea LEAVES GROWN AROUND TEMBOGA RIVERBANK, BENIN CITY NIGERIA

EMOMU Adams*, OGBE Victor Etunim

Heavy metal levels in soils may result in heavy metal entry into the food chain, the study aimed at accessing concentration of heavy metals (Cd, Ni, Pb) in soils, Talinium triangulare and C. argentea leaf grown along Temboga Riverbank. Surface (0-15 cm) soil, T. triangulare and C. argentea leaf samples were collected randomly from Temboga Riverbank (RB), 60 meters from RB (60MRB) and 120 meters fr...
