    • Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil 

      Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R.; Opala, P. A.; Maghanga, J. K.; Agalo, Jerry; Ng'etich, W. K.; Kisinyo, Joyce; Osiyo, R. J.; Nekesa, A. O.; Makatiani, E. T.; Odee, D. W.; Ogola, B. O. (2015-07-21)
      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 ...

    • Immediate and residual effects of lime and phosphorus fertilizer on soil acidity and maize production in western Kenya 

      Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R; Opala, P. A.; Ng'etich, W. K.; Nyambati, R.O.; Ouma, Evans Ochieng; Agalo, Jerry; Kebeney, S.J; Too, E.J; Kisinyo, Joyce; Opile, W.R. (2015-08-21)
      Soil acidity and phosphorus (P) deficiency are some of the major causes of low maize yields in Kenya. This study determined the immediate and residual effects of lime and P fertilizer on soil pH, exchangeable aluminium ...

    • Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya 

      Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R.; Opala, P. A.; Maghanga, J. K.; Ng'etich, W. K.; Agalo, Joyce; Opile, R.W.; Kisinyo, Joyce; Ogola, B. O. (2015-08-21)
      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 ...
