Abstract
Different fertilizers, ammonia sulfate and urea (MIN), Fertil 12.5 (ORG) and Azoslow (ORG-MIN) were compared in a silage corn crop. Total biomass yield was above 55.0 t ha-1 for all fertilizers. Azoslow showed the highest dry matter content (40.8%). No differences among the fertilizers were found in protein content (4.9% on average) at waxy ripening, with the control showing the lowest value (3.9%). There were also no differences in silage quality among the fertilizers. The N budget was estimated in order to quantify the residual nitrogen amounts at harvest and the efficiency of fertilizers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
