Seed threshing: by prolonged stomping on a burlap sack filled with seeds the seed coats came loose (nobody liked this job).	Now the seeds go into the winnowing mill.	How the winnowing mill works.
Cleaned and with their coats removed they roll out.	Pine seed for sale.	Here the seeds have been sown in beds. To the right newly sown beds, to the left 2 beds with 1-year-old plants (in the background the pressure roller).
2-year-old plants now planted out in rows.		Analysis results.
