• ELECTROCOAGULATION METHOD FOR COLOUR REMOVAL IN TEA EFFLUENT: A CASE STUDY OF CHEMOMI TEA FACTORY IN RIFT VALLEY, KENYA 

  Justin K. Maghanga; Fred K. Segor; Lazare Etiégni; John Lusweti (Chemical Society of Ethiopia, 2009)

  A simple and efficient electrochemical method that utilizes two steel electrodes and is capable of reducing the colour of tea effluent prior to its discharge into the river system has been developed. The effects of potential ...
• Polycyclic Aromatic Hydrocarbon Gaseous Emissions from Household Cooking Devices: A Kenyan Case Study 

  Chiedza F. Munyeza; Aloys M. Osano; Justin K. Maghanga; Patricia B.C. Forbes (Environmental Toxicology and Chemistry, 2019)

  In developing countries, household energy use is highly variable and complex, yet emissions arising from fuel combustion indoors are typically poorly quantified. Polycyclic aromatic hydrocarbons (PAHs) are emitted during ...
• Phosphorus sorption and lime requirements of maize growing acid soils of Kenya 

  P. O. Kisinyo; C. O. Othieno; SO Gudu; J. R. Okalebo; P. A. Opala; JR Okalebo; PA Opala; J. K. Maghanga; W. K. Ng’etich; J. Agalo; R. W. Opile; J. A. Kisinyo; B. O. Ogola (Sustainable Agriculture Research, 2013)

  In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ...
• Impact of Nitrogen Fertilizer Applications on Surface Water Nitrate Levels within a Kenyan Tea Plantation 

  J. K. Maghanga; J. L. Kituyi; P. O. Kisinyo; W. K. Ng’etich (Journal of Chemistry, 2013)

  Tea production in the Kenyan Ri Valley uses high rates of nitrogenous fertilizer. Nitrates can be discharged to water bodies through leaching and surface run-off. Nitrate levels above 10 mg/L NO3−–N cause methemoglobinemia ...
• Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil 

  P. O. Kisinyo; S. O. Gudu; C. O. Othieno; J. R. Okalebo; P. A. Opala; J. K. Maghanga; J. J. Agalo; W. K. Ng'etich; J. A. Kisinyo; R. J. Osiyo; A. O. Nekesa; E. T. Makatiani; D. W. Odee; B. O. Ogola (African Journal of Agricultural Research, 2012)

  Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania (Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia populations that nodulate ...
