The information on analytical techniques that are used for soil and plant analyses in different agricultural laboratories of Kenya was gathered and compiled in table forms. Performance of six laboratories was compaired for different elements and parameters of soil and plant samples. Chemical analysis of identical samples was conducted for parameters/elements according to the participating laboratories\' procedures. The results obtained by these laboratories using the same extraction procedures were compaired. Primary data that was obtained from the six different analytical laboratories appears to be useful in the completed comparative studies on methodologies and quality aspects in Kenyan agricultural laboratories.
