Effects of a municipal solid waste compost and mineral fertilization on plant growth in two tropical agricultural soils of Mali.

摘要: Abstract A pot experiment was conducted to compare the effects of compost and mineral fertilization on growth chemical composition ryegrass ( Lolium perenne L.) in two Malian agricultural soils (Baguineda, abbreviated as Bgda, 12°23 ′ S, 7°45 W Gao, 16°18 N, 0° GM). Treatments included: control, NPK alone, NPK+C 25 , 50 100 PK+C NK+C NP+C K+C P+C N+C C where represents non-modified Hoagland’s solution (corresponding 271, 95 172 kg/ha P K respectively) different rates (25, T/ha) compost. Compost significantly increased dry matter production. The application T/ha alone yield by 10% 17.5% while 69.7% 65% for Gao Bgda soils, respectively. combination (NPK+C Bgda) showed highest crop yields. Increases soil organic carbon, available P, Fe, Mn, Zn, Cu, pH were observed treatments with Therefore, appeared be a good supplier nutrients tropical soils.
