This paper provides the research results of beef cattle granular organic compost fertilizers use and spread by centrifugal spread machinery. For research were used beef cattle granular organic compost fertilizers. For granules making was used matrix with 6 mm and 4 mm holes. There were investigated particle geometrical parameters and aerodynamic features of granular organic compost fertilizers, estimated critical particle speed, coefficient of flutter and others parameters. There were valued influences of geometrical parameters to particle aerodynamic features. Spread equal distributions of granular fertilizers were investigated using fertilizers spreaders “Amazon ZA-M-1201”, fertilizers rate – 750 kg.ha-1 and 1000 kg.ha-1, harvest site – 14 m.
