"Electrodyne" bench.Forestry Commission,Corris,Wales. Used for applying an electrostatically charged spray of persistent insecticide to forestry plants prior to planting.The conveyor is earthed and thus ensures that the spray only attaches to the plants. Efforts to minimise chemical use as well as the withdrawl of many insecticides have encouraged research into other methods of control of Hylobius and Hylastes. Field scale use of nematodes and stump removal have given promising results. |

seeding or sowing |
|
After the seedbeds are formed, the seed is sown. Some nurseries sow in the fall so that the seeds can undergo natural stratification. Spring sowing is more common, however, and begins as soon as soil temperatures are warm enough. Larger nurseries use seed drills which sow the seed in 6 to 8 rows per seedbed. Some seed drills automatically cover the seed with soil, whereas others leave the seed exposed so that it can be covered with a mulch. The number of seeds that are sown per area of seedbed is determined by a ‘sowing factor’ that includes information on seed germination, desired seedling growing density, expected seedling survival etc |

root pruning |
|
The lateral roots between the seed rows are also pruned with a vertical root pruner. This piece of equipment is sometimes "belly-mounted" under the tractor which allows precise placement by the tractor operator. |

lifting, grading, & storage |
|
Lifting consists of drawing an inclined, vibrating blade under the seedlings, usually at a depth of about one foot. The inclined blade lifts the seedlings out of the seedbed and the vibrating action loosens the soil from around the roots. |

lifting, grading, & storage |
|
Storage containers are transported to a cooler where they are kept at temperatures near freezing to maintain dormancy and cold hardiness. Each box is marked with the proper seed source code which describes the origin of the seedlot. |
