Concept:A broadcast crop planter is a sowing machine that distributes seeds over a large area of land without planting them in rows.
Explanation:Broadcast planting works by randomly scattering seeds across the soil surface.
It does not form ridges, furrows, or planting holes.
The seeds are simply thrown or dropped over the whole field in an even but unorganized pattern.
This method is different from row crop planters, which sow seeds along ridges.
It is also different from precision planters, which place an exact number of seeds in holes with regular spacing.
Furthermore, grain drill planters sow seeds in straight rows with spacing between rows.
Therefore, the main purpose of a broadcast crop planter is to scatter seeds randomly about the field.
After scattering, the seeds are often covered lightly by harrowing or rolling.
Answer:Option C: to plant seeds by random scattering of seeds about the field.
