Mining sites occupy vast areas of arable land. After extraction, soils of these sites become poor and can’t improve plants yields. Mining activities destroy natural habitats, deracinate many plants and kill some animals. However, these sites are an important biological value if they are well maintained. Sika-Kondji mining site is not exempt from these problems. For this, we suggest to contribute to restoration of soil site fertility and it's biodiversity using free available wastes materials from the plant and career. With the wastes (green, food, limestone and clay wastes) composting, we will attract animals and fertilize soils. On soils amended with composts, various plants such as food crops (Z. mays, G. max, A. esculentus) will grow to attract insect by their flowers and leaves. For the profit of company and society, these crops will produce food and citronella will produce essential oil for local soaps improving and as bioinsecticid. At the end of this project, Sika-kondji quarry soil and surrounding villages are fertilized and their biodiversity is restored. Mining site of Sika-Kondji generates profits for the company and surrounding villages. Key words: wastes, composts, Insects, Plants, quarry, biodiversity improvment, economic.

Maize and citronella yields

C2 (food wastes compost) and C4 (food wastes + green wastes + limestones and clay) are the best for maize Production on the top soil! C1 (green wastes compost) is the best for essential oil produduction on the topsoil! Nature is the winner!

Data collection!

It's been over an month since we started our work! The objective of this part is to attract animals from the composting process! Research question is what type of waste can better attract animals and fertilize the topsoil SiKa Kondji career. For this we made the composts by free materials more available, natural habitats (Cases with clay and limestone waste mre available), pond with clay and feeders using PVC box.

Types de composts

4 types de composts avec la méthode en tas pour répondre à 2 questions de recherche: - Quel est le meilleur type de matériaux putrescibles qui attire la faune pendant le compostage? - Quel est le meilleur type de compost qui fertilise le top sol, améliore la production et la qualité des cultures?
