Inades-Formation Burkina organized on October 26, 2022 in Korsimoro a restitution session of the results of an experiment concerning the effects of biofertilizer commonly called “liquid compost” on tomato and onion crops. This experiment was conducted in Korsimoro, Sanmatenga Province, North Central Region of Burkina Faso, with support from Brooke West Africa.

To scientifically evaluate and document the agronomic and economic performance of liquid compost ” is the mission entrusted to Dr Hamadou Sigué by Inades-Formation Burkina. ” After a number of years of promoting liquid compost to growers, we wanted to take a break to scientifically evaluate and document the yield effects and economic benefits of this local natural fertilizer. “said Isidore Della, Director of Inades-Formation Burkina. The experiment was carried out in a farming environment for three months on tomato and onion plants with the participation of six market gardeners. The plot used for the experiment is located in a market gardening area east of the commune of Korsimoro. Dr. Hamadou Sigué was assisted in the experimentation process by the local agricultural officer and two endogenous facilitators from Inades-Formation Burkina.

The President of the special delegation of the commune of Korsimoro was present to set the tone for the workshop on the results of the experiment

The experiment consisted in putting liquid fertilizer in competition with three other levels of fertilization: NPK, solid compost and zero fertilizer. Three blocks were formed for testing onion and tomato crops. Each of the blocks was subjected to five levels of fertilization. For level 1, the liquid biofertilizer was diluted to 10%; it was diluted to 15% for level 2. At level 3, solid compost was used. As for level 4, the test was carried out with the chemical fertilizer NPK. Level 5 was without fertilizer application

Dr. Sigué’s presentation at the Korsimoro restitution showed that the cost/benefit analysis distinguished the liquid biofertilizer diluted at 15% as the formula that gave the best result in terms of fertilization compared to the other fertilizers used in the experiment. And Dr. Sigué concludes: “the liquid biofertilizer is likely to be recommended to market gardeners producing tomatoes and onions.

A farmer who has already used liquid compost in her field and who was present at the feedback session was already convinced when she said: ” Liquid compost is a very useful product for producers. Its production does not require money. It is made of elements that are easily available to us, such as tree leaves, animal droppings, etc. “She adds: ” We thank Inades-Formation Burkina for having put us on this path. The feedback session brought together producers, representatives of the local agricultural and environmental technical services, and the president of the special delegation of the commune of Korsimoro.

Inades-Formation Burkina initiated the experimentation on “liquid compost” in the perspective of promoting the scaling up of the use of liquid compost as an alternative to chemical inputs. This will be done with producers who, once convinced of the benefits of this fertilizer, will produce and market it. ” We hope that this experimentation will not only be an addition to the existing documentation, but that it will serve the cause of agroecology in a concrete way,” said the Director of Inades-Formation Burkina.
