There is a long history of agricultural mechanization that has been human and animal powered rather than engine powered. The difference in scale is quite staggering and is a measure of the economic gulf between the rich and the poor on this planet. For example, an average horse plowing the soil at an average rate will perform work at a rate of one horsepower (hp). In contrast, a 100 hp (75 kW) tractor could work (e.g. plowing the soil) at a rate one hundred times faster than the horse.
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.
