What is it about?
Declining soil fertility is a major constraint for vegetable crops like lettuce in sub-Saharan Africa. With the purpose of contributing to enhancing crop yields and soil productivity, while safeguarding the environment, this study aims to assess the effect of composts made from chicken droppings (CCD) and horse dung (CHD) on soil quality after lettuce growing.

Why is it important?
The results of the phytotoxicity test showed that the lowest germination percentages were obtained at V1C2100%Ster+ (48.33±6.01%) and V2C2100%Ster+ (53.33±6.01%). These values were around the standard (50%), showing that these composts were non-toxic. The results showed that overall, the composts improved soil properties, with significant increases in P and Ca content. So, soil Ca contents of C0, C1, C2 and C3 were respectively 2, 3, 2 and 2 times that of Ct. CCD and CHD can be therefore recommended for growing lettuce and maintaining soil quality.
Perspectives
Writing this article was a great pleasure because it was co-authored by co-authors with whom I have had long-standing collaborations. This article led to the development of organic fertilizers improving soil quality.
