Background

Agriculture in Burkina Faso is an important sector in terms of development of national economy and ensuring employment, which is contributing 22% of the national GDP and more than 80% of people in Burkina Faso engaged in agriculture. The agricultural productivity has been stagnant because Burkina Faso is located under the severe climate condition in Sahel area where rainfall pattern is unstable and soil fertility is low. In order to increase the agricultural productivity, agricultural inputs such as fertilizer is necessary at some level. However, most of the farmers cultivate without using fertilizer, and one of the main reasons is that price of chemical fertilizer, mostly imported, is quite high. Phosphorus is extremely important as one of the main nutrients of plant nutrition for crop cultivation, but it is pointed out that 80% of soil in Africa is deficient in phosphorus which causes critical limitation of agricultural productivity. In recent years, a depletion of phosphorus is a deep international concern and the price of phosphorus is on the upward trend. On the other hand, Burkina Faso has phosphate resources, and it is estimated the resource amount is 100 million tons. The country's expectation on development and utilization of phosphate resources is high, and it started to consider construction of a plant to fabricate phosphate fertilizer using phosphate rock. It is expected to reduce the price only by replacing imported phosphorus compounds with indigenous one. In this way, it is expected to increase the country's stable agricultural production by manufacturing phosphate fertilizer which has high fertilizing effect and compound fertilizer from it, then by providing cheaper fertilizer than imported one to farmers. Accordingly, it has to-be established a technology for manufacturing phosphate and compound fertilizer from phosphate resources of Burkina Faso.

Project Purpose

To establish an applicable "model for fertilizing cultivation promotion" with use of Burkina Faso phosphate rock (BPR) in consultation with Ministry of Agriculture and Hydraulic Layouts (MAAH) and other stakeholders.

Subjects and Activities

The project is constituted with 4 major subjects as follows:

 

Subject 1   Development of regionally adapted compound fertilizers using national phosphate rock (Development of national fertilizers)
Subject 2   Evaluation of fertilizing effect on the major crop, and improvement and dissemination of fertilization (Enhancement of fertilizing cultivation)
Subject 3   Development direct utilization technology of phosphate rock (Rock phosphate direct application)
Subject 4   Proposal of comprehensive utilization methods of rock phosphate to realize sustainable crop production (Rock phosphate comprehensive use)
