Tillage
Site preparation is critical for successful revegetation projects. Preparation can include land scraping followed by tilling to remove compacted layers, improving soil tilth, destroying weeds, and providing a firm, friable seedbed with safe sites for seeded species. Tillage implements are classified as primary and secondary.
Primary tillage refers to the first and often most aggressive type of soil preparation resulting in a rough seedbed requiring additional tillage or finishing before being ready to seed or plant.
Secondary tillage typically follows primary tillage to produce finer soil particles.
There are many pieces of equipment used to level, create water catchment, or improve seed soil contact in loose soils.
