Save Disposal of Wastewater in Irrigation and its Effect on Soil Properties under Khartoum Conditions
Ali Widaa Mohammed Elamin, Amir Bakheit Saeed
The objective of this study is to investigate the effect of disposal of wastewater in irrigation on soil properties. Samples of treated wastewater were analyzed for pH, SAR, EC in dS/m, while, Na, Cl, NH4-N, HCO3, CO3 and heavy metals in mg/l. The soil samples were taken from three depths D1(0-20), D2 (20-40) and D3 (40-60) and analyzed for fore mention parameters. The results showed that the conc
Performance Study of Fins and Tube Heat Exchanger with Different Fin Geometry
R. Jegede, J. E. Ogbezodea, and C. J. Diji
In various engineering devices, a considerable amount of thermal energy has to be dissipated through a small area using extended surfaces referred to as fins. The insufficient rate of thermal energy dissipation in heat exchangers has created a high demand for more powerful engines in smaller hood spaces. For this reason, a two- phased study was carried out to examine the relationship between varyi
Performance Evaluation of Small Scale Irrigation Schemes By Using Process and Comparative Indicators: Case Study on Golina and Kokono Small Scale Irrigation Schemes, North Wollo Zone, Amhara Region, Ethiopia
Ketema Feye Ayane
The study was conducted to evaluate the performance of two small scale irrigation schemes at north Wollo zone, Amhara regional state using process and comparative performance indicators. The irrigation schemes were Golina and Kokono with command area of 400ha and 80ha respectively. Primary data collection includes measuring discharge at diversion weir, soil moisture before and after irrigation and
Effect of Inter Spaces and Emitter Types on the Hydraulic Performance of Drip Irrigation System
Ali Widaa Mohammed Elamin , Hassan Awadalla Abdala Ahmed
This study was conducted at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum – Shambat, during May 2011 to February 2012, to investigate the effect of inter-space and emitter type on hydraulic performance of drip irrigation system. The farm lies at E and N and 380 m above mean Sea level. Two types of emitters were used, online pressure compensation (Eo) and inline labyr
Improving Adaptive Water and Nutrient Management in Food Value Chains for Climate Change Adaptation: A Case of Sensor Technology in Malawi
Isaac R. Fandika, Richard Stirzaker, Geoffrey Mwepa, Grivin Chipula, Jonathan Chikankheni, Herbert Kumwenda, Horace Kakhiwa
Soil water and nutrient management for climate-smart agriculture by smallholder farmers have typically been by trial and error. Studies were conducted to adapt the use of sensor farmer–friendly monitoring technology in measuring soil water and nutrients with the aim of improving the efficiency of resources in the food value chain. Simple monitoring tools (chameleon and Wetting Front Detector) whic
