Therefore, this study quantified soil GHG emissions using static chambers for two maize cropping seasons (one full year) of four different soil amendments in the central highlands of Kenya. The four treatments were: (i) animal manure; (ii) inorganic fertiliser; (iii) combined animal manure and inorganic fertiliser; and (iv) a no N-control (no amendment) laid out in a randomised complete block design.
