Borrero, GonzaloFriesen, Dennis K.Oberson, AstridRodríguez, M.Rao, Idupulapati M.[Destinos de fósforo aplicado como fertilizante en oxisoles de los Llanos Orientales de Colombia: fraccionamiento secuencial]Destinos de fósforo aplicado como fertilizante en oxisoles de los Llanos Orientales de Colombia: fraccionamiento secuencial

Earthworms are considered soil ecosystem engineers that play an important role in soil organic matter dynamics and physical structure. Due to both their size and activities these organisms can accelerate the decomposition and mineralization of organic matter by reducing the size of residues to pa...
