Precision seeders place single seeds at predetermined intervals in evenly spaced rows to provide an optimum plant population using pretreated seeds suited to mechanical metering under gravity and with high germination and establishment potential. Plants with lesser germination potential or those requiring an earlier growing date (rice, tomatoes, cabbage, lettuce, tobacco) may be transplanted typically in biodegradable containers in which the seedling has been established in greenhouses.
During the nineteenth century many attempts were made to develop harvesting machinery in Europe and the United States.
