Municipal sewage sludge from wastewater treatment is an important nutritional source for sustainable agriculture. Here, we report on the assessment of the accumulation of heavy metals in Nile tilapia Oreochromis niloticus (Trewavas 1983) fed on earthworms Eisenia fetida reared on soil treated with different concentrations of sewage sludge (25% and...

Problem statement: Sudan is the largest (2.5 million km2) country most seriously affected by desertification in Africa. The arid and semi-arid lands cover an area of 1.78 million km2, which represents about 72% of the country’s total area1. Sudan has collaborated with and contributed to the International efforts to combat desertification. It is one...

The paper focused on the achievement and challenges of the Sudanese women working in research institutions in Sudan

Purpose – A laboratory experiment was conducted in the soil laboratory in the Department of Environment and Environmental Pollution, Environment and Natural Resources Research Institute, National Centre for Research. The purpose of this paper is to study the movement of crude oil through soil column. Design/methodology/approach – Polyvinyl chlorid...

Purpose – The purpose of this paper is to investigate the influence of two decomposition processes, namely, composting and vermicomposting, on the chemical composition of the finished products of a mixture of: cotton residues; soil and cotton residues; farmyard; soil. Design/methodology/approach – Composting experiments were done over six months t...

This study focused on impact of sediment laden water of the Nile - especially during flood season - on viscosity, rheological properties and flow characteristics of water within water network and piping systems. Laboratory experiments, performed at the National Research Centre Laboratories at Khartoum, were conducted on water samples collected from...

Abstract Purpose: The aim of this study was to investigate the biodegradation of petroleum hydrocarbons in crude oil when added to Shambat soil in Sudan. Design/methodology/approach: A laboratory experiment was conducted in the Soil Science Unit laboratories at the Department of Environment and Environmental Pollution, ENRRI, National Center for Re...

Organic fertilizer was produced using organic manure amended with soil samples with different mixing ratios. The soil served as reservoir of the minerals produced during decomposition e.g. Nitrate; which helped in improving compost quality and reduce the loss of minerals as nitrate and carbon dioxide gases. Also the temperature during decomposition...

Purpose: The effort were made to study the effect of organic fertilization (compost and vermicompost) produced from cotton residues and farmyard manure as well as to compare between the effects of organic fertilizer in comparison with inorganic fertilizers on Teff grass (Eragrostis tef Zucc.Trotter) as a test crop. Design: Two pot experiments were...
