The aim of our study was to find an
alternative to the use of chemical fertilizers which not only
degrade the soil but cause global warming. To achieve this, seven
composts were made from three domestic waste (plantain peelings,
cassava peelings, and yam peelings at 100% and also their mixtures
two to two at 50% then at three 1/3). These different composts were
characterized and their chemical properties were determined and then
compared to those of the six others, to the ENPRO compost (made in
Togo) and also to those of the soil from the Akouédo landfill. The
analysis of the results of the mineral composition of the composts
showed that the C7 compost is the richest in minerals and has the
same amount of nitrogen as the ENPRO compost. It has also been
demonstrated that the compost of crushed plantain peels (C3) used
alone or in mixtures with the compost of yam and/ or cassava peels
(C5, C6 and C7) mineralizes and rapidly releases nutrients to make
them available to plants. These organicfertilizers (elaborated
composts C3, C5, C6, and C7) could, therefore, constitute an
alternative to the use of chemical fertilizers and be recommended to
farmers, because they are rich in minerals, accessible, cheap, and
easy to produce. |
