Fertilizer and residue quality effects on organic matter stabilization in soil aggregates por Fonte, Steven J., Yeboah, E., Ofori, P, Quansah, GW, Vanlauwe, Bernard, Six, Johan

“…This study examined the influence of organic residue quality and N fertilizer on aggregate-associated SOM in maize cropping systems of southern Ghana. Six residue treatments of differing quality (Crotalaria juncea, Leucaena leucocephala, maize stover, sawdust, cattle manure and a control with no residues added) were applied at 4 Mg C ha-1 yr-1 both with and without fertilizer N additions (120 kg N ha-1 season-1). …”

Genetic diversity of some Ghanaian pigs based on microsatellite markers por Ayizanga, R.A., Kayang, B.B., Adomako, K., Adenyo, C., Inoue-Murayama, M., Asamoah, L.

“…To this end, the genetic diversity of some local pigswas assessed by genotyping 86 unrelated pigs in four regions of Ghana namely Northern (Tingoli = 9), Upper West (Papu = 31 and Babile = 32) and Upper East (Gia = 14) using 12 microsatellite markers.The number of alleles (Na), number of effective alleles (Ne), observed heterozygosity (Ho), expected heterozygosity (He) and inbreeding coefficient (FIS) were used to assess the level of genetic differentiation among the five populations in this study. …”
