These are pea seeds ready to plant. As you can see the planter has a white circle plate wheel that rotates around picking up one pea seed in each opening which is then dropped below it and the planter has cut a row which the seed is dropped into and then covered up. The seeds do have a pink seed inoculant on them. Inoculation is a farming practice that helps farmers give their crops a productive start to the season, improving plant vigor and return-per-acre potential each year. noculants encourage the formation of high-nitrogen nodules on plant roots for richer soil, bigger plants, and better yields.
