Manejo de Suelos - Fertilización, Compostado, Nutrición vegetal

Respuesta del cultivo de papa a la combinación de diferentes fuentes de fertilización nitrogenada: Evaluando la hipótesis de la sincronización.

  Se ha propuesto que combinando enmiendas orgánicas de diferente calidad con fertilizantes minerales puede mejorarse la utilización del nitrógeno por los cultivos al sincronizar la demanda de N con su disponibilidad en el suelo. El objetivo fue evaluar si bajo este...
