Small holder farmers in Africa do not currently have access to fast and reliable soil testing services, and as a result lack the necessary soil information to purchase the correct inputs for increasing their yields. To meet this need in Kenya, we have developed a professional Soil Testing and SMS Fertilizer Use advisory service, called Daktari wa Udongo (Soil Doctor), specifically for small holder farmers.

The main objective of the Daktari wa Udongo service is to deliver timely and integrated fertilizer recommendations to the smallholder farmer by SMS, which gives them the knowledge and advice to improve their crop yields through building soil health and improving fertilizer management. By utilizing this service and following through with the recommendations given, small holder farmers are able toimprove the productivity, profitability and sustainability of their farms.


This service is supported and implemented by appointed and professionally trained agent network distributed throughout all agricultural productive counties in Kenya.The service utilizes ICT and mobile phone solutions which combine innovation, science and technology to communicate with these farmers.

Daktari wa Udongo Service, through its many years’ experience and expertise in soil testing, can competently supply farmers with soil amendments inputs and fertilizer management recommendations based on the soil results. As a service, do not sell any farm inputs, so our advice is always independent.

Through the Daktari wa Udongo Service, we are bringing world class laboratory and soil fertility advisory services to small holder farmers who have, in the past been marginalised from getting such agronomic services.
