METHOD OF PRODUCING HIGH NITROGEN TYPE CHICKEN DROPPING FERTILIZER

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a high nitrogen type chicken droppings fertilizer having nitrogen content stable throughout the year and having high nitrogen content. SOLUTION: The method of producing the high nitrogen type chicken droppings fertilizer includes: a separation bleeding step of separating a chick of egg-collecting chicken from an adult chicken starting egg-collection and bleeding them; a transportation step of separating the droppings excreted from the chick and the droppings excreted from the adult chicken which are separated and bled and transporting the droppings from a hen house; and a fertilizer making step of making the chicken droppings fertilizer using the chicken droppings. In the fertilizer making step, the nitrogen-containing chemical fertilizer is mixed with the chicken droppings fertilizer and rice bran is added to the mixed chicken droppings fertilizer and formed into pellets.
