The process in which water, grass seed, fertilizer, cellulose fiber, and a glue type material are mixed together and sprayed onto the soil to establish turf is called_____________.

1. Hydroseeding

2. Top dressing

3. Pressure spray

4. Seed Injection

The correct answer is: Hydroseeding

Hydroseeding is a method that involves mixing water, grass seed, fertilizer, cellulose fiber, and a glue-like material to create a slurry that is then sprayed onto the soil. This process allows for an efficient and effective way to establish turf over large areas. The cellulose fiber acts as a mulch to aid in moisture retention and provide a protective layer that encourages seed germination. The glue helps to bind the mixture together, promoting uniform coverage and improving the adhesion of the seed to the soil. In contrast, top dressing generally refers to the application of a thin layer of material such as soil or compost over existing turf to improve its health and appearance, rather than starting a new lawn. Pressure spray is a broader term that does not specifically indicate the inclusion of seeds or fertilizers in its application. Seed injection typically refers to inserting seeds directly into the ground rather than applying a slurry mixture, which is another method distinct from hydroseeding. Thus, hydroseeding is the most appropriate term describing this specific mixture and application for establishing new turf.
