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.
The pace of mechanization is influenced by three other economic factors: capital scarcity and energy costs, farm size, and subsidies. Capital scarcity and energy costs. Poor societies have smaller capital stocks than rich ones, and the cost of capital (in terms of labor) is higher. High capital costs retard mechanization in several ways.
