Effects of Parent Material and Land Use on the Variability of Available Cu in a Wetland Soil Under Long - Term Farming System

Eteng, E.U.*

The study was carried out in the dry season to evaluate the variation in available Cu in wetland soil under long-term farming systems. Twenty four surface (0-20 cm) composite soil samples of acidic nature were obtained and analyzed for available Cu in the soils using five extractants (0.01M HCl, Coca-cola, 0.05M EDTA, 0.05M DTPA, and 1N NH4OAc) respectively. Some important soil char-acteristics li...

Appraisal and Mapping of Soil Salinity and Sodicity Problems in Sector One of Watari Irrigation Scheme, Kano State.

Bashir A.Y*, Samndi A. M., Adam M.A, Moji K.T, Auwal M.

One of the main reasons for the loss of productive land in irrigated fields is the buildup of salinity in the soil. In the watari irrigation Scheme, no systematic ap-praisal and mapping have been made before within the sector. The study area was selected after a reconnaissance survey based on the farmer's complaint about the low production. Global positioning system (GPS) was used to record the co...

Comparative Effect of Groundnut (arachis Hypogea L.) Genotypes on Yield and N Fixation in Sudan and Northern Guinea Savannahs of Nigeria

Moji K.T*, Jibrin M. J., Umar F. G., Bashir A.Y

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero Univer...

Effects of Different Organic Amendment Sources on the Physico Chemical Properties of a Nutrient Depleted Vertisol

Moji K.T*, Jibrin M. J., 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...

Characterization and Classification of the Soils of Bukuru - Jos, North Central Nigeria

Kwaghe, E.J.*, Akamigbo, F.O.R., Igwe, C.L

Twelve profile pits were sunk, four in each of the three locations of Bukuru, the study area. Proper soil profile description was done and recorded to obtain field characterization data after which thirty-six soil samples were collected from all the genetic horizons for soil characterization. Bukuru soils showed higher sand fraction (71%) than silt (12%) and clay (17%) at the topsoil but showed in...

Evaluation and Classification of Soil Fertility Potentials of Gombi Area of Adamawa State, Northeastern Nigeria

Johnson, A., Saddiq A. M., Solomon, R. I*, Ibrahim, A., Waizah, Y

A study was conducted to evaluate the soil fertility potential of Gombi area of Adamawa State, Nigeria. A total of eighty (80) soil samples composite from 0-20 and 20-50cm depths were collected from selected representative locations from the ten (10) wards of the study area and analyzed using standard laboratory procedures. Results obtained revealed that the texture of the soil ranged from sandy l...

Short - Term Effect of Soil Tillage and Npk Fertilization Rates on Soil Carbon Sequestration and Yield of Colocasia Esculenta Schott in Two Micro - Environments in Se, Nigeria

ANIKWE M.A.N*, Ikengannyia E. E

Quantification of soil organic carbon cycling as impacted by soil and crop man- agement practices is required for C storage and soil quality improvement investi- gations. This study assessed the short-term effect of conventional tillage (CT) and No-Tillage (NT) practices on SOC sequestration and yield of cocoyam (Colocasia esculenta). The experiment was conducted simultaneously at two lo- cations ...

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...

Nwagbara, M.O*, Irondi, A.O., Uzoma, K.C, Adesemuyi E.A

In this study, predictive model for estimating the soil thermal conductivity and diffusivity from fourteen different sample points around a horizontal gas flaring site was employed in two depths (0 – 15 cm and 15 – 30 cm). Seven of these points were within the gas flare bond wall. In contrast, other points were located outside the bond wall at varying distances in the direction of the flaring. Soi...
