Where it is realized
Summary description of agroecological practice
The practice I'd like to map is the use of biochars in agriculture, through the valorization of crop residues.
Type of agroecological practice
It's an agricultural production cooperative.
We adopted this practice based on the use of biochar because our soil in Kinshasa is very sandy and acidic.
By using biochar, we can combat the acidity of these soils thanks to biochar's neutralizing power, and reduce watering time because biochar increases the soil's water and nutrient retention capacity.
Biochar is a promising tool for carbon sequestration because of its ability to remain stable in the soil for hundreds or even thousands of years. In fact, biochar produced from agricultural waste is estimated to sequester up to 1.2 t C ha-1 year-1.
Implementing the practice
We put this practice into practice by experimenting in the field.
Why you use and what you expect from this practice?
We use this practice because it is very promising and better adapted to Kinshasa's acid sandy soil conditions.
Land size
Substitution of less ecological alternative
Details
But sometimes we use chemical fertilizers in microdose form.
