Hydroseeding and hydromulching have emerged as powerful tools in the business of vegetation establishment.
Invented in the 1940s, hydroseeding introduced the idea of mixing seed and water together. The mixture could easily be sprayed over steep slopes, providing seed dispersal and irrigation at the same time.
Over time, these mixtures became increasing complex, including mulch to assist with surface erosion control, nutrient additives, and much more. This course covers how the hydro-mulching industry provides powerful solutions for effective erosion control and vegetation establishment.
Upon successful completion of this course, learners should be able to:
- Describe how hydroseeding and hydro-mulching technology have added value to the important business of vegetation establishment
- Describe the best management practices and the important role this emerging technology is playing in revegetation
- Explain how design tools and testing can assist in making the best choices for site specific solutions
- List several of the principle industry changing innovations and improvements that have fueled the rapid expansion and growth of hydraulically applied vegetative solutions
