Drill and Broadcast Seeding
Drill Seeding
Drillseeding is the method of mechanically pressing seed into the ground. As in agriculture a tractor mounted machine moves across prepaired soils and presses seed from a hopper into the ground at a set depth of 0.1 to 25 mm. No harrowing of further soil preparation is required after drillseeding is completed. However, this process still leaves your site with exposed soils, and some form of mulch for erosion control is recommended such as straw or hydromulch.
Broadcast Seeding

Broadcast seeding is the method of spreading seed on the ground with a cyclone spreader. It is usually accompanied by mixing the seed into the soil with harrows. It is the most economical method of applying seed to large scale areas of land, or to areas which will be covered with erosion control blankets.
