Impact of biochars and local fertilizers on the production of the three crops (okra, eggplant and yam)

Description

For an integrated management of the fertility of this sandy soil of Kinshasa, the use of mineral fertilizers should be accompanied by an adequate application of organic matter. Biochar is very important to improve the problem of water retention and nutrients to be brought to this type of soil. Since the price of fertilizers and biochar is not always affordable for small farmers, the use of castor leaves, which are accessible and easy to collect at no cost, is economically profitable. In addition, the yield obtained, compared to that of the combination of fertilizer and biochar, there is no difference.
Faced with the exacerbated pressures on soil and water resources currently, the use of biochar in agriculture is a solution not only to solve the problem of soil fertility but also to fight against the harmful effects of climate change by sequestering carbon. in the ground.
The current climate change must push farmers to change the way they use the soil and give it an amendment that will allow it to maintain its fertility for a long time to finally ensure food security.
