Abstract
A pellet made of dried, unfermented livestock manure has N, P and K values in the range of N: 3 to 7 g/kg, as ammoniac and organic nitrogen, P: 2 to 6 g/kg as phosphorus pentoxide and K: 2 to 6 g/kg as potassium oxide (g/kg). The pellet has a hardness exceeding 10 kg and has a shell composed of manure-base lignin. A press roll, including a hollow rotatable drum with a perforated screen, may be used in combination with an endless belt and a scraper to produce the pellet.
