Mooriit arap Sang, a resident of Ainamoi Constituency, Kericho County, informs Public Eye that for a long time, multinational tea estates in his county were used to the rather labour-intensive application of NPK fertiliser on their tea plantations.
In order to cut costs, Arap Sang says, most of the tea firms have now embraced the more cost-effective method of aerial application of the fertiliser. This method involves spreading of fertiliser on farms from an agricultural aircraft.
