A seed distribution system comprising: at least one first row unit (110) and a second row unit (120) adapted to distribute seeds and arranged adjacent to each other or in a staggered configuration or both, each row unit including : a seed distribution device (26) adapted to provide a distribution action for a plurality of seeds (30)； a drive assembly (112, 122) configured to drive the seed distribution device； a sensor (116, 126) adapted to detect at least one seed passage and generate a signal corresponding to the seed passage； and an individual row controller (102) operatively coupled to the drive assembly of each row unit and configured to receive the sensor signals, assign distance labels for each seed related to a seed position in a groove below each of the first and second row units, and to determine if the seed separation is at a desired level, characterized in that the individual row controller is further configured to store signals from the sensors of each row unit until a first row unit sample size and a second row unit sample size； and to combine the first and second sample size to generate a third sample size that simulates a single row seed separation configuration.Un sistema de distribución de semillas que comprende: al menos una unidad de primera fila (110) y una unidad de segunda fila (120) adaptadas para distribuir semillas y dispuestas adyacentes entre sí o en una configuración escalonada o ambas, cada unidad de fila incluyendo: un dispositivo de distribución de semillas (26) adaptado para proporcionar una acción de distribución para una pluralidad de semillas (30)； un conjunto de accionamiento (112, 122) configurado para accionar el dispositivo de distribución de semillas； un sensor (116, 126) adaptado para detectar al menos el paso de una semilla y generar una señal correspondiente al paso de semillas； y un controlador de fila individual (102) acoplado operativamente al conjunto de accionamiento de cada unidad de fila y configurado para recibir l
